Plasma xanthine oxidoreductase (XOR) activity in patients with cardiopulmonary arrest (CPA) has not yet been studied.A total of 1,158 patients who required intensive care and 231 control patients who attended a cardiovascular outpatient clinic were prospectively analyzed. Blood samples were collected within 15 minutes of admission from patients in intensive care patients, which were divided into a CPA group (n = 1,053) and a no-CPA group (n = 105). Plasma XOR activity was compared between the 3 groups and factors independently associated with extremely elevated XOR activity were identified using a multivariate logistic regression model. Plasma XOR activity in the CPA group (median, 1,030.0 pmol/hour/mL; range, 233.0-4,240.0 pmol/hour/mL) was significantly higher than in the no-CPA group (median, 60.2 pmol/hour/mL; range, 22.5-205.0 pmol/hour/mL) and control group (median, 45.2 pmol/hour/mL; range, 19.3-98.8 pmol/hour/mL). The regression model showed that out-of-hospital cardiac arrest (OHCA) (yes, odds ratio [OR]: 2.548; 95% confidence interval [CI]: 1.098-5.914; P = 0.029) and lactate levels (per 1.0 mmol/L increase, OR: 1.127; 95% CI: 1.031-1.232; P = 0.009) were independently associated with high plasma XOR activity (≥ 1,000 pmol/hour/mL). Kaplan-Meier curve analysis indicated that the prognosis, including all-cause death within 30 days, was significantly poorer in high-XOR patients (XOR ≥ 6,670 pmol/hour/mL) than in the other patients.Plasma XOR activity was extremely high in patients with CPA, especially in OHCA. This would be associated with a high lactate value and expected to eventually lead to adverse outcome in patients with CPA.

The time-dependent changes in the simultaneous evaluation of B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP) levels during hospitalization for acute heart failure (AHF) remain obscure.A total of 356 AHF patients were analyzed. Blood samples were collected within 15 minutes of admission (Day 1), 48-120 hours (Day 2-5) and between days 7 and 21 (Before-discharge). Plasma BNP and serum NT-proBNP were significantly decreased on Days 2-5 and Before-discharge in comparison to Day 1, but the NT-proBNP/BNP ratio was not changed. Patients were divided into 2 groups according to the median NT-proBNP/BNP (N/B) ratio on Day 2-5 (Low-N/B versus High-N/B). A multivariate logistic regression model showed that age (per 1-year increase), serum creatinine (per 1.0-mg/dL increase), and serum albumin (per 1.0-mg/dL decrease) were independently associated with High-N/B (odds ratio [OR]: 1.071, 95%confidence interval [CI]: 1.036-1.108, OR: 1.190, 95%CI: 1.121-1.264 and OR: 2.410, 95%CI: 1.121-5.155, respectively). Kaplan-Meier curve analysis showed that the High-N/B group had a significantly poorer prognosis than the Low-N/B group, and a multivariate Cox regression model revealed that High-N/B was an independent predictor of 365-day mortality (hazard ratio [HR]: 1.796, 95%CI: 1.041-3.100) and HF events (HR: 1.509, 95%CI: 1.007-2.263). The same trend in prognostic impact was significantly observed in both low and high delta-BNP cohorts (< 55% and ≥ 55% BNP value on the start date/BNP value at 2-5-days).A high NT-proBNP/BNP ratio on Day 2-5 was associated with non-cardiac conditions and was associated with adverse outcomes even if BNP was adequately decreased by the treatment of AHF.

Few studies on sudden death (SD) after admission for acute heart failure (AHF) have been published. A total of 1,664 patients with AHF were enrolled in this study, and 1,261 patients who were successfully followed up during the first year after admission were analyzed. The primary end point was SD, which was defined as out-of-hospital cardiac arrest. The median follow-up period from admission was 1,008 days (range 408 to 2,132). In total, 505 patients (40.0%) died: 341 (67.5%) died of cardiovascular causes and 55 (10.9%) died of other causes. Of the 505 who died, 80 (15.8%) experienced SD. The proportion of SDs increased in the later phases of follow-up (0 to 1 year, 10.3%; 1 to 2 years, 18.0%; 2 to 5 years, 18.8%; ≥5 years, 28.2%; p &lt;0.001). A multivariate logistic regression model showed that younger age was independently associated with SD (60 to 69 years: odds ratio 2.249, 95% confidence interval 1.060 to 4.722; &lt;60 years: odds ratio 3.863, 95% confidence interval 1.676 to 8.905). Kaplan-Meier curves showed that the incidence of cardiovascular death was highest during the acute phase, whereas the incidence of SD increased gradually over the entire follow-up period. In conclusion, the incidence of SD was surprisingly high in patients with AHF, accounting for 16% of long-term mortality. The proportion of SDs increased during the very late follow-up phases.

AIM: The role of serum type III procollagen peptide (P3P) level in the acute phase of acute heart failure (AHF) requires clarification. We hypothesized that serum P3P level is temporarily higher during the acute phase, reflecting liver dysfunction due to congestion. METHODS AND RESULTS: A total of 800 AHF patients were screened, and data from 643 patients were analysed. Heart failure was diagnosed by the treating physician according to the European Society of Cardiology (ESC) guidelines, and included patients being treated with high-concentration oxygen inhalation (including mechanical support) for orthopnea, inotrope administration, or mechanical support for low blood pressure, and various types of diuretics for peripheral or pulmonary oedema. In all cases, diuretics or vasodilators were administered to treat AHF. The patients were divided into three groups according to their quartile (Q) serum P3P level: low-P3P (Q1, P3P ≤ 0.6 U/mL), mid-P3P (Q2/Q3, 0.6 < P3P <1.2 U/mL), and high-P3P (Q4, P3P ≥ 1.2 U/mL). The plasma volume status (PVS) was calculated using the following formula: ([actual PV - ideal PV]/ideal PV) × 100 (%). The primary endpoint was 365 day mortality. A Kaplan-Meier curve analysis showed that prognoses, including all-cause mortality and heart failure events within 365 days, were significantly (P < 0.001) worse in the high-P3P group when compared with the mid-P3P and low-P3P groups. A multivariate logistic regression analysis showed that high PVS (Q4, odds ratio [OR]: 4.702, 95% CI: 2.012-20.989, P < 0.001), high fibrosis-4 index (Q4, OR: 2.627, 95% CI: 1.311-5.261, P = 0.006), and low estimated glomerular filtration rate per 10 mL/min/1.73 m2 decrease (OR: 1.996, 95% CI: 1.718-2.326, P < 0.001) were associated with high P3P values. The Kaplan-Meier curve analysis demonstrated a significantly lower survival rate, as well as a higher rate of heart failure events, in the high-P3P and high-PVS groups when compared with the other groups. A multivariate Cox regression model identified high P3P level and high PVS as an independent predictor of 365 day all-cause mortality (hazard ratio [HR]: 2.249; 95% CI: 1.081-3.356; P = 0.026) and heart failure events (HR: 1.586, 95% CI: 1.005-2.503, P = 0.048). CONCLUSION: A high P3P level during the acute phase of AHF served as a comprehensive biomarker of liver dysfunction with volume overload (i.e. liver congestion) and renal dysfunction. A high P3P level at admission may be able to predict adverse outcomes in AHF patients.

A 25-year-old woman diagnosed as having a non-massive pulmonary embolism and deep vein thrombosis from the right superficial femoral to the right common iliac vein was treated by deployment of a DENALI® Vena Cava Filter. Filter retrieval was attempted 6 months later using a BARD snare retrieval kit. However, the conventional technique was unsuccessful because of a tilt and attachment of the filter head to the vessel wall. Hence, we passed an EN Snare Endovascular Snare System through an Amplatz Left 1 guiding catheter to successfully penetrate the attached portion of the filter hook and vessel wall. This combination provided controlled direction and a strong backup force that helped capture and retrieve the filter. This technique could be an alternative method to retrieve inferior vena cava filter with severe tilt and tight attachment to the vena cava wall when the conventional technique is unsuccessful.

Background: Low-triiodothyronine (T3) syndrome is a known complication in intensive care unit (ICU) patients, but the underlying mechanisms and prognostic impact are unclear. Methods and Results: This study retrospectively enrolled 2,976 patients who required care in the ICU. Of these patients, 2,425 were euthyroid and were divided into normal (n=1,666; free T3 [FT3] ≥1.88 µIU/L) and low-FT3 (n=759; FT3 <1.88 µIU/L) groups. Multivariate logistic regression analysis revealed that prognostic nutritional index >46.03 (odds ratio [OR] 2.392; 95% confidence interval [CI] 1.904-3.005), age (per 1-year increase; OR 1.022; 95% CI 1.013-1.031), creatinine (per 0.1-mg/dL increase; OR 1.019; 95% CI 1.014-1.024), and C-reactive protein (per 1-mg/dL increase; OR 1.123; 95% CI 1.095-1.151) were independently associated with low FT3. Survival rates (within 365 days) were significantly lower in the low-FT3 group. A multivariate Cox regression model showed that low FT3 was an independent predictor of 365-day mortality (hazard ratio 1.785; 95% CI 1.387-2.297). Low-T3 syndrome was significantly more frequent in patients with non-cardiovascular than cardiovascular diseases (73.5% vs. 25.8%). Prognosis was significantly poorer in the low-FT3 than normal group for patients with cardiovascular disease, particularly those with acute coronary syndrome and acute heart failure. Conclusions: Low-T3 syndrome was associated with aging, inflammatory reaction, malnutrition, and renal insufficiency and could lead to adverse outcomes in patients admitted to a non-surgical ICU.

AIMS: Serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP) levels are rarely evaluated simultaneously in the acute phase of acute heart failure (AHF). METHOD AND RESULTS: A total of 1207 AHF patients were enrolled, and 1002 patients were analysed. Blood samples were collected within 15 min of admission. Patients were divided into two groups according to the median value of the NT-proBNP/BNP ratio [low-NT-proBNP/BNP group (Group L) vs. high-NT-proBNP/BNP group (Group H)]. A multivariate logistic regression model showed that the C-reactive protein level (per 1-mg/dL increase), Controlling Nutrition Status score (per 1-point increase), and estimated glomerular filtration rate (eGFR, per 10-mL/min/1.73 m2 increase) were independently associated with Group H [odds ratio (OR) 1.049, 95% confidence interval (CI) 1.009-1.090, OR 1.219, 95% CI 1.140-1.304, and OR 1.543, 95% CI 1.401-1.698, respectively]. A Kaplan-Meier curve analysis showed that the prognosis was significantly poorer in Group H than in Group L, and a multivariate Cox regression model revealed Group H to be an independent predictor of 180-day mortality [hazard ratio (HR) 3.084, 95% CI 1.838-5.175] and HF events (HR 1.963, 95% CI 1.340-2.876). The same trend in the prognostic impact was significantly observed in the low-BNP (<810 pg/mL, n = 501), high-BNP (≥810 pg/mL, n = 501), and low-eGFR (<60 mL/min/1.73 m2, n = 765) cohorts, and tended to be observed in normal-eGFR (≥60 mL/min/1.73 m2, n = 237) cohort. CONCLUSION: A high NT-proBNP/BNP ratio was associated with a non-cardiac condition (e.g. inflammatory reaction, nutritional status, and renal dysfunction) and is independently associated with adverse outcomes in AHF.

The Fibrosis-4 (FIB4) index could indicate the liver fibrosis in patients with chronic hepatic diseases. It was calculated using the following formula: (age × aspartate aminotransferase [U/L]) / (platelet count [103/μL] × √alanine aminotransferase [U/L]). However, the clinical impact of the FIB4 index in the acute phase of acute heart failure (AHF) has not been sufficiently investigated.A total 1,468 AHF patients were analyzed. The median FIB4 index was 2.71 [1.85-4.22]. The patients were divided into three groups according to the quartiles of their FIB4 index (low-FIB4 [Q1, ≤ 1.847], middle-FIB4 [Q2/Q3, 1.848-4.216], and high-FIB4 [Q4, ≥ 4.216] groups). A Kaplan-Meier curve analysis showed that the prognosis, such as all-cause mortality and HF events within 365 days, was significantly poorer in the high-FIB4 group than in the middle-FIB4 and low-FIB4 groups. A multivariate Cox regression model identified high FIB4 index as an independent predictor of 365-day all-cause death (hazard ratio (HR): 1.660, 95% CI: 1.136-2.427) and HF events (HR: 1.505, 95% CI: 1.145-1.978). The multivariate logistic regression analysis showed that the high plasma volume status (PVS) (Q4, odds ratio [OR]: 2.099, 95% CI: 1.429-3.082), low systolic blood pressure (SBP) (< 100 mmHg, OR: 3.825, 95% CI: 2.504-5.840), and low left ventricular ejection fraction (< 40%, OR: 1.321, 95% CI: 1.002-1.741) were associated with a high FIB4 index.A high FIB4 index can predict adverse outcomes in AHF patients, which indicate that congestive liver and liver hypoperfusion occur due to low cardiac output in the acute phase of AHF.

Ongoing myocardial damage at the acme of the sepsis status has not been sufficiently evaluated. The clinical data of 160 sepsis patients who require intensive care and 127 outpatients with chronic heart failure (HF) were compared as a retrospective cohort study. Thereafter, the sepsis patients were divided into 3 groups according to the serum heart-type fatty acid-binding protein (H-FABP) quartiles [low H-FABP = Q1 (n = 39), middle H-FABP = Q2/Q3 (n = 81), and high H-FABP = Q4 group (n = 40)]. The H-FABP level was measured within 15 min of admission. The serum H-FABP levels in the sepsis patients [26.6 (9.3-79.0) ng/ml] were significantly higher than in the choric HF patients [6.6 (4.6-9.7) ng/ml]. A Kaplan-Meier curve showed that the survival rate of the high-H-FABP group was significantly lower than that of the middle- and low-H-FABP groups. The multivariate Cox regression analysis for the 365-day mortality showed that the high-H-FABP group (hazard ratio: 6.544, 95% confidence interval [CI] 2.026-21.140; p = 0.002) was an independent predictor of the 365-day mortality. The same trend in the prognostic impact was significantly (p = 0.015) observed in the cohort that had not been suffering from the cardiac disease before admission. The serum H-FABP level was an independent predictor of the 365-day mortality in the patients who were emergently hospitalized in the intensive-care unit due to sepsis. Ongoing myocardial damage was detected in the majority of patients with sepsis, suggesting that ongoing myocardial damage might be a candidate predictor of adverse outcomes in sepsis patients.

AIMS: The aim of present study is to evaluate the clinical significance of the time-dependent changes in xanthine oxidoreductase (XOR) activity during hospitalization for acute heart failure (AHF). METHODS AND RESULTS: A total of 229 AHF patients who visited to emergency room were prospectively enrolled, and 187 patients were analysed. Blood samples were collected within 15 min of admission (Day 1), after 48-72 h (Day 3), and between Days 7 and 21 (Day 14). The AHF patients were divided into two groups according to the XOR activity on Day 1: the high-XOR group (≥100 pmol/h/mL, n = 85) and the low-XOR group (<100 pmol/h/mL, n = 102). The high-XOR patients were assigned to two groups according to the rate of change in XOR from Day 1 to Day 14: the decreased group (≥50% decrease; n = 70) and the non-decreased group (<50% decrease; n = 15). The plasma XOR activity significantly decreased on Days 3 and 14 [23.6 (9.1 to 63.1) pmol/h/mL and 32.5 (10.2 to 87.8) pmol/h/mL, respectively] in comparison with Day 1 [78.5 (16.9 to 340.5) pmol/h/mL]. A Kaplan-Meier curve indicated that the prognosis, including heart failure (HF) events (all-cause death and readmission by HF) within 365 days, was significantly poorer in the low-XOR patients than in the high-XOR patients and was also significantly poorer in the non-decreased group than in the decreased group. CONCLUSIONS: The plasma XOR activity was rapidly decreased by the appropriate treatment of AHF. Although high-XOR activity on admission was not associated with increased HF events in AHF, high-XOR activity that was not sufficiently reduced during appropriate treatment was associated with increased HF events.

Novel biomarkers of rheumatoid arthritis (RA), in addition to antibodies against cyclic citrullinated peptides, are required. Metabolome analysis is a promising approach to identify metabolite biomarkers for clinical diagnosis. We adopted a comprehensive non-targeted metabolomics approach combining capillary electrophoresis time-of-flight mass spectrometry (TOFMS) and liquid chromatography TOFMS. We constructed metabolomics profiling of 286 plasma samples of a Japanese population [92 RA patients, 13 systemic lupus erythematosus (SLE) patients and 181 healthy controls). RA case-control association tests showed that seven metabolites exhibited significantly increased levels in RA samples compared with controls (P < 1.0 × 10-4; UTP, ethanolamine phosphate, ATP, GDP, ADP, 6-aminohexanoic acid and taurine), whereas one exhibited a decreased level (xanthine). The plasma levels of these eight metabolites were not significantly different between seropositive and seronegative RA patients (P > 0.05; n = 68 and 24, respectively). The four nucleotide levels (UTP, ATP, GDP and ADP) were significantly higher in the non-treatment patients in comparison between patients with and without treatment (P < 0.014; n = 57 and 35, respectively). Furthermore, we found that none of the four nucleotide levels showed significant differences in SLE case-control association tests (P > 0.2; 13 patients with SLE and the 181 shared controls) and psoriatic arthritis (PsA) case-control association tests (P > 0.11; 42 patients with PsA and 38 healthy controls), indicating disease specificity in RA. In conclusion, our large-scale metabolome analysis demonstrated the increased plasma nucleotide levels in RA patients, which could be used as potential clinical biomarkers of RA, especially for seronegative RA.

BACKGROUND AND AIMS: Peripheral artery disease (PAD), intermittent claudication, and impaired mobility contribute to the loss of skeletal muscle. This study investigated the impact of endovascular treatment (EVT) in patients suffering from PAD above the knee and its relation to baseline glycemic control. METHODS AND RESULTS: Mid-thigh muscle volume was measured before EVT, 3 months after EVT and 6 months after EVT. Mid-thigh muscle volumes of ipsilateral PAD patients with ischemic and non-ischemic legs were compared. Correlations between total thigh muscle volume and clinical characteristics were analyzed using univariable and multivariable analysis. Overall, thigh muscle volume increased after EVT. The mid-thigh muscle volume was significantly lower in patients with ipsilateral lesions and in those with ischemic lower limbs. The thigh muscle volume of those with ischemic lower limbs increased after EVT. Baseline glycated hemoglobin was the only factor that was negatively correlated with changes in the muscle volume after EVT. Muscle volume significantly increased in normoglycemic HbA1c<6.5% (47 mmol/mol) patients. There was no significant alteration in the muscle volume of hyperglycemic HbA1c ≥ 6.5% patients. CONCLUSION: Ischemic muscle atrophy was ameliorated after EVT in normoglycemic patients. There is a need for a large-scale trial to investigate whether EVT can protect or delay skeletal muscle loss.

The prognostic impact of transfer to another hospital among acute heart failure (AHF) patients has not been well elucidated.Of the 800 AHF patients analyzed, 682 patients were enrolled in this study for analysis. The subjects were divided into two groups according to their discharge location: discharge home (Group-H, n = 589) or transfer to another hospital for rehabilitation (Group-T, n = 93). The Kaplan-Meier curves revealed a poorer prognosis, including all-cause death and heart failure (HF) events (death, readmission-HF), in Group-T than that in Group-H (P < 0.001, respectively). A multivariate Cox regression model showed that Group-T was an independent predictor of 365-day all-cause death (hazard ratio: 2.618, 95% confidence interval [CI]: 1.510-4.538, P = 0.001). The multivariate logistic regression analysis showed that aging (per 1-year-old increase, odds ratio [OR]: 1.056, 95% CI: 1.028-1.085, P < 0.001), female gender (OR: 2.128, 95% CI: 1.287-3.521, P = 0.003), endotracheal intubation during hospitalization (OR: 2.074, 95% CI: 1.093-3.936, P = 0.026), and increased Controlling Nutritional Status score on admission (per 1.0-point increase, OR: 1.247, 95% CI: 1.131-1.475, P < 0.001) were associated with transfer to another hospital after AHF admission. The prognosis, including all-cause death, was determined to be significantly poorer in patients who were transferred to another hospital, as their activities of daily living were noted to lessen before discharge (n = 11) compared to others (n = 82).Elderly AHF patients suffering from malnutrition were difficult to discharge home after AHF admission, and transfer to another hospital only led to adverse outcomes. Appropriate rehabilitation during definitive hospitalization appears necessary for managing elderly patients in the HF pandemic era.

Background: Serum calcium (Ca) concentrations in the acute phase of acute heart failure (AHF) have not been not sufficiently investigated. Methods and Results: This study enrolled 1,291 AHF patients and divided them into 3 groups based on original and corrected Ca concentrations: (1) hypocalcemia (both original and corrected Ca ≤8.7 mg/dL; n=651); (2) pseudo-hypocalcemia (original and corrected Ca ≤8.7 and >8.7 mg/dL, respectively; n=300); and (3) normal/hypercalcemia (both original and corrected Ca >8.7 mg/dL; n=340). AHF patients were also divided into 2 groups based on corrected Ca concentrations: (1) corrected hypocalcemia (corrected Ca ≤8.7 mg/dL; n=651); and (2) corrected normal/hypercalcemia (corrected Ca >8.7 mg/dL; n=640). Of the 951 patients with original hypocalcemia (≤8.7 mg/dL), 300 (31.5%) were classified as corrected normal/hypercalcemia after correction of Ca concentrations by serum albumin. The prognoses in the pseudo-hypocalcemia, low albumin, and corrected normal/hypercalcemia groups, including all-cause death within 730 days, were significantly poorer than in the other groups. Multivariate Cox regression analysis showed that classification into the pseudo-hypocalcemia, hypoalbumin, and corrected normal/hypercalcemia groups independently predicted 730-day all-cause death (hazard ratios [95% confidence intervals] of 1.497 [1.153-1.943], 2.392 [1.664-3.437], and 1.294 [1.009-1.659], respectively). Conclusions: Corrected normal/hypercalcemia was an independent predictor of prognosis because this group included patients with pseudo-hypocalcemia, which was affected by the serum albumin concentration.

A 79-year-old man, with a history of atrial fibrillation, presented with a sudden onset of intermittent claudication of the left lower limb. The angiogram revealed a thrombotic total occlusion in the left superficial femoral artery (SFA). A 10-Fr sheath was antegradely inserted into the left common femoral artery (CFA), and the guidewire penetrated the lesion. Thrombo-aspiration using the 8-Fr long sheath into the 10-Fr short sheath was performed repeatedly. Intravenous anticoagulant was administrated immediately after the endovascular treatment. Follow-up angiogram performed 12 days after the procedure confirmed the absence of any residual thrombus in the SFA. Thrombo-aspiration, using a large-diameter catheter, is a feasible strategy for the treatment of acute and subacute limb ischemia, and is cost-effective.

Hyperuricemia is known to be associated with adverse outcomes in cardiovascular intensive care patients, but its mechanisms are unknown. A total of 569 emergency department patients were prospectively analyzed and assigned to intensive care (ICU group, n = 431) or other departments (n = 138). Uric acid (UA) levels were significantly higher in the intensive care patients (6.3 [5.1-7.6] mg/dl vs. 5.8 [4.6-6.8] mg/dL). The plasma xanthine oxidoreductase (XOR) activity in the ICU group (68.3 [21.2-359.5] pmol/h/mL) was also significantly higher than that in other departments (37.2 [15.1-93.6] pmol/h/mL). Intensive care patients were divided into three groups according to plasma XOR quartiles (Q1, low-XOR, Q2/Q3, normal-XOR, and Q4, high-XOR group). A multivariate logistic regression model showed that lactate (per 1.0 mmol/L increase, OR 1.326; 95%, CI 1.166-1.508, p < 0.001) and the Acute Physiology and Chronic Health Evaluation II score (per 1.0 point increase, OR 1.095, 95% CI 1.034-1.160, p = 0.002) were independently associated with the high-XOR group. In-hospital mortality was significantly higher in the high-XOR group (n = 28, 26.2%) than in the normal- (n = 11, 5.1%) and low- (n = 9, 8.3%) XOR groups. The high-XOR group (vs. normal-XOR group) was independently associated with the in-hospital mortality (OR 2.934; 95% CI 1.170-7.358; p = 0.022). Serum UA levels and plasma XOR activity were high in patients admitted to intensive care. The enhanced XOR activity may be one of the mechanisms under which hyperuricemia was associated with adverse outcomes in patients requiring cardiovascular intensive care.

Background: Whether the dose of loop diuretics can be decreased by administration of a sodium-glucose cotransporter 2 (SGLT2) inhibitor in diabetic outpatients with compensated heart failure (HF) is unclear. Methods and Results: This study prospectively enrolled 60 diabetic outpatients with compensated HF. Patients were randomly divided into 2 groups: those administered the SGLT2 inhibitor empagliflozin (n=28) and those not (n=30). Changes in the daily dose of loop diuretics, blood sampling data, and urinary renal tubular biomarkers were evaluated 6 months after the intervention. The median (interquartile range) furosemide dose decreased significantly over the 6-month follow-up period in the empagliflozin group (from 40 [20-40] to 20 [10-20] mg), but not in the non-empagliflozin group (from 23 [20-40] to 40 [20-40] mg). Hemoglobin levels increased significantly in the empagliflozin group (from 13.2 [11.9-14.6] to 14.0 [12.7-15.0] g/dL). In addition, excretion of acetyl-β-D-glucosaminidase decreased significantly over the 6-month follow-up in the empagliflozin group (from 4.8 [2.6-11.7] to 3.3 [2.1-5.4] IU/L), especially in the group in which the dose of loop diuretics decreased (from 4.7 [2.5-14.8] to 3.3 [2.1-4.5] IU/L). Conclusions: Empagliflozin administration decreased the dose of loop diuretics and increased the production of erythropoietin, which may help prevent renal tubular injury in diabetic outpatients with HF.

BACKGROUND: The factors associated with a low plasma xanthine oxidoreductase (XOR) activity were not elucidated in patients with acute heart failure (AHF). METHODS: Two-hundred and twenty-nine AHF patients who visited the emergency department were prospectively analyzed. AHF patients were divided into 3 groups according to the plasma XOR quartiles (Q1 = low-XOR group [n = 57], Q2/Q3 = middle-XOR group [n = 115], and Q4 = high-XOR group [n = 57]). The prognostic nutritional index (PNI) and the controlling nutritional status (CONUT) score were evaluated. RESULTS: The multivariate logistic regression model showed that the nutritional status (PNI: OR 1.044, 95% CI 1.000-1.088; CONUT: OR 3.805, 95% CI 1.158-12.498), age, and serum creatinine level were independently associated with a low plasma XOR activity. The Kaplan-Meier curve showed a significantly lower incidence of heart failure events in the low-XOR group than in the middle + high-XOR group (hazard ratio, HR 1.648, 95% CI 1.061-2.559). In particular, a low XOR activity with an increased serum creatinine level (>1.21 mg/dL) was independently associated with heart failure events (HR 1.937, 95% CI 1.199-3.130). CONCLUSION: A low plasma XOR activity was associated with malnutrition, renal dysfunction, and aging in AHF. A low XOR activity complicated with renal dysfunction leads to adverse long-term outcomes.

The mechanisms of urgently presenting acute heart failure (AHF) are not clear. We evaluated the serum catecholamine values of AHF patients immediately after admission. A total of 1,475 AHF patients were screened, and 484 who were admitted from their homes and in whom serum catecholamine could be evaluated immediately after admission were analyzed. The patients were divided into three groups according to the time interval from the onset of symptoms to admission (OA): < 3 hours (early-OA group; n = 283), 3-24 hours (middle-OA group; n = 142), and ≥24 hours (late-OA group; n = 59). In the early-OA group, the systolic blood pressure (SBP) was significantly higher, orthopnea was more frequent, the pH value was significantly decreased, and the use of noninvasive positive-pressure ventilation was required significantly more often than in the other groups. The serum noradrenaline level was significantly increased in the early-OA group (1.96 [1.02-3.60] ng/mL) than in the middle-OA (1.49 [0.73-3.41] ng/mL) and late-OA (1.40 [0.91-2.42] ng/mL) groups, and the adrenaline level was significantly increased in the early-OA group (0.36 [0.13-1.17] ng/mL) than in the late-OA (0.22 [0.09-0.52] ng/mL) group. A multivariate logistic regression model indicated the early-OA group was independently associated with the SBP > 140 mmHg (odds ratio [OR]: 2.219, 95% CI: 1.375-3.581), midnight/early morning admission (OR: 3.158, 95% CI: 2.048-4.868), and high serum catecholamine value (adrenaline > 0.96 ng/mL, noradrenaline > 3.39 ng/mL, and dopamine > 0.21 ng/mL) (OR 2.091, 95% CI: 1.161-3.767). In conclusion, urgently presented AHF might be induced by an endogenous catecholamine surge, which causes an excessive rise in blood pressure leading to increased after-overload and volume-shift lung congestion.

BACKGROUNDS: The prevalence of atrial fibrillation (AF) has been increasing in aging societies. The prognostic impact of AF associated with worsening heart failure (HF) remains obscure. METHODS AND RESULTS: We analyzed 1170 acute heart failure (AHF) patients who required intensive care. Patients were assigned to two groups according to the prevalence of AF: no episode of AF (n = 940) and pre-existing AF (Group-1, n = 230). Patients with no episode of AF (n = 940) were further divided into two groups according to presence of new-onset of AF after admission (Group-2a, n = 258) or not (Group-2b, n = 682). Kaplan-Meier curve analysis showed that prognosis, including all-cause mortality and HF-events within 1000 days, was significantly poorer in the Group-1 compared to the Group-2b. However, a multivariate Cox regression model showed that the Group-1 was not an independent predictor of 1000-day mortality and HF-events. Furthermore, Kaplan-Meier curve analysis showed that prognosis, including all-cause mortality and HF-events within 1000 days, was significantly poorer in the Group-2a than in the Group-2b. A multivariate Cox regression model revealed that the Group-2a was an independent predictor of 1000-day mortality (HR: 1.403, 95% CI: 1.018-1.934) and HF-events (HR: 1.352, 95% CI: 1.071-1.708). A multivariate logistic regression model showed that only age (≥75 years old) was independently associated with new-onset of AF after admission (odds ratio: 1.556, 95% CI: 1.130-2.143). CONCLUSIONS: New-onset AF associated with worsening HF increases with age and is independently-associated with adverse outcome in patients with AHF.

Low triiodothyronine (T3) syndrome has recently been evaluated as a prognostic marker of acute heart failure (AHF). However, in which cases low T3 syndrome typically leads to adverse outcomes remain unclear. Of 1,432 AHF patients screened, 1,190 were enrolled. Euthyroidism was present in 956 patients (80.3%), who were divided into 2 groups: the normal group (n = 445, FT3 ≥1.88 µIU/L) and low-FT3 group (n = 511, FT3 <1.88 µIU/L). The survival rates and event-free rates within 365 days were significantly lower in the low-FT3 group than in the normal group. A multivariate Cox regression model showed that the low-FT3 group was an independent predictor of 365-day mortality (hazard ratio [HR] 1.429, 95% confidence interval [CI] 1.013 to 2.015) and HF events (HR 1.349, 95% CI 1.047 to 1.739). The multivariate logistic regression analysis revealed that age (per 10-year old increase, odds ratio [OR]: 1.186, 95% CI: 1.046 to 1.345) and prognostic nutritional index (PNI; per 1-point increase, OR: 1.067, 95% CI: 1.046 to 1.089) were independently associated with the low-FT3 group. The prognosis in patients with a low PNI and over 75 years old, including all-cause death within 365 days, was significantly poorer in the low-FT3 group than in the normal group. In conclusion, adverse outcomes were predicted by the presence of low T3. AHF patients with low T3 syndrome are strongly associated with aging and malnutrition. Low T3 syndrome complicated with older age and malnutrition is likely to lead to adverse outcomes in patients with AHF.

Background: Plasma volume status (PVS) has been evaluated recently as a prognostic marker of acute heart failure (AHF). However, whether evaluating PVS alone is sufficient remains unclear. Methods: Of 675 patients with AHF screened, 601 were enrolled. The PVS, prognostic nutritional index (PNI) (lower = worse), and Controlling Nutritional Status (CONUT) score (higher = worse) were evaluated. Patients were divided into 2 groups according to PVS value (low- or high-PVS group) and were further subdivided into 4 groups (low- or high-PVS/CONUT group and low- or high-PVS/PNI group). Results: A Kaplan-Meier curve showed a significantly lower survival rate in the high-PVS group than in the low-PVS group, the high-PVS/high-CONUT group than in the high-PVS/low-CONUT group, and the high-PVS/low-PNI group than in the high-PVS/high-PNI group. A multivariate Cox regression model showed that high PVS (hazard ratio [HR], 1.642; 95% confidence interval [CI], 1.049-2.570) and high PVS/high CONUT (HR, 2.076; 95% CI, 1.147-3.757) and high PVS/low PNI (HR, 2.094; 95% CI, 1.166-3.761) were independent predictors of 365-day mortality. Conclusions: An adverse outcome was predicted by the evaluation of PVS; furthermore, a malnutrition status with a high PVS leads to an adverse outcome. The simultaneous evaluation of nutrition status and PVS is essential to predict an AHF outcome.

Background:
The features of sleep-associated acute heart failure (AHF) patients admitted at midnight or early morning (M/E) are unclear.
Methods and Results:
Of 1,268 AHF patients screened, 932 were analyzed, and divided into 2 groups by admission time (M/E group, 23:00-06:59, n=399; daytime group, 07:00-22:59, n=533). Those in the M/E group were further divided by the presence of a prodrome: with (n=176; prodrome group) or without (n=223; sudden onset group). The median time from symptom onset to hospitalization was significantly shorter in the M/E group (98 min; range, 65-170 min) than in the daytime group (123 min; range, 68-246 min). The 365-day HF event rate in the M/E group was significantly lower than that of the daytime group. On multivariate logistic regression modeling the M/E group was independently associated with a better outcome than the daytime group (OR, 0.673; 95% CI: 0.500-0.905). In the M/E group, the 365-day HF event rate was significantly lower in the prodrome group than in the sudden onset group. On multivariate logistic regression modeling, inclusion in the prodrome group was independently associated with a better outcome (OR, 0.544; 95% CI: 0.338-0.877).
Conclusions:
AHF patients admitted during sleeping hours were not sicker than those admitted during the daytime. The absence of a prodrome, however, might be associated with future repeated HF events.

AIMS: Coronary angioscopy (CAS) is a robust imaging methodology for evaluation of vascular healing response after stenting. However, the procedure requires a guiding catheter with a diameter of more than 6 Fr, which is rather invasive at follow-up angiography. Recently, coronary angioscopes of a smaller diameter have been able to pass through a 4 Fr guiding catheter. This study aimed to investigate the feasibility and safety of slender CAS observation using a 4 Fr guiding catheter. METHODS AND RESULTS: Thirty-three consecutive patients who underwent follow-up angiography were evaluated. Following usual angiography via the radial artery, the stent segment was observed by non-occlusive CAS through a 4 Fr guiding catheter. Low molecular weight dextran-L (4 mL/sec) was flushed from a guiding catheter to replace coronary blood. The success rate, anatomical or procedural factors related to the success, and incidence of adverse events were examined. The success rate was 84.8% (n=28/33). The luminal diameter at the orifice of the target vessel was larger in the successful than in the failed group (4.03±0.61 mm vs. 3.39±0.61 mm, respectively; p=0.009). The presence of deep engagement of the guiding catheter into the target vessel was a key factor for sufficient observation (100% in the successful group vs. 0% in the failed group; p<0.0001). No adverse events, such as dissection or acute coronary syndrome, were reported. CONCLUSIONS: The new method of CAS through a 4 Fr guiding catheter demonstrated high feasibility and safety. This less invasive observation via CAS may be useful for stent follow-up.

Background: The association between social factors and the long-term prognosis of acute heart failure (AHF) remains unclear. Methods and results: One thousand fifty-one AHF patients were screened, and 915 were enrolled. Four hundred forty-two AHF patients ≥75 years of age (the elderly cohort) were also included in a sub-analysis. Participants who fulfilled one of the three marital status-, offspring-, and living status-related criteria were considered socially vulnerable. On this basis they were classified into the socially vulnerable (n = 396) and non-socially vulnerable (n = 519) groups in the overall cohort, and the socially vulnerable (n = 219) and non-socially vulnerable (n = 223) groups in the elderly cohort. Kaplan–Meier curves showed that the survival rate of the socially vulnerable group was significantly poorer than that of the non-socially vulnerable group in the overall (p = 0.049) and elderly (p = 0.004) cohorts. A multivariate Cox regression model revealed that social vulnerability was an independent predictor of 1000-day mortality in the overall [hazard ratio (HR): 1.340, 95% confidence interval (CI): 1.003–1.043, p = 0.048] and elderly cohort (HR: 1.531, 95% CI: 1.027–2.280, p = 0.036). Regarding the components of social vulnerability, the marital status was an independent factor in the elderly cohort (HR: 1.500, 95% CI 1.043–2.157, p = 0.029). Conclusion: Social vulnerability was independently associated with long-term outcomes in AHF patients, especially in the elderly cohort. Organization of the social structure of AHF patients might be able to improve their prognosis.

Atherosclerotic diseases sometimes contribute to acute heart failure (AHF). The aim of the present study is to elucidate the prognostic impact of AHF with atherosclerosis. A total of 1226 AHF patients admitted to the intensive care unit were analyzed. AHF associated with atherosclerosis was defined by the etiology: atherosclerosis-AHF group (n = 708) (patients whose etiologies were ischemic heart disease or hypertensive heart disease) or AHF not associated with atherosclerosis (non-atherosclerosis-AHF) group (n = 518). Kaplan–Meier curves showed that the survival rate of the atherosclerosis-AHF group was significantly better than that of the non-atherosclerosis-AHF group within 730 days of follow-up. Regarding pre-hospital medications, atherosclerosis-AHF patients were more likely to be administered nitroglycerin (20.3 vs. 13.7%, p = 0.003), nicorandil (18.8 vs. 7.5%, p &lt
0.001), angiotensin-converting enzyme inhibitor (ACE-I) or angiotensin II receptor blocker (ARB) (46.5 vs. 38.6%, p = 0.006), β-blocker (33.2 vs. 26.6%, p = 0.014) and statin (30.1 vs. 22.4%, p = 0.003) because of a previous coronary event or atherosclerotic diseases. In sub-group analysis of medication including administered ≥ 3 drugs within 5 medications and ACE-I/ARB, atherosclerosis-AHF significantly decreased the rate of all-cause death within 180 days (hazard ratio (HR) 0.215, 95% CI 0.078–0.593 and HR 0.395, 95% CI 0.244–0.641, respectively) with a significant interaction (p value for interaction 0.022 and 0.005, respectively). Kaplan–Meier curves showed that the 180-days survival rate of the atherosclerosis-AHF group with ACE-I/ARB and ≥ 3 drugs were significantly better than other groups. The AHF patients associated with atherosclerosis lead to be a good long-term outcome. A relationship may exist between efficient treatment including ACE-Is before admission and a good outcome in mid-term.

The prognostic impact of a decreased blood glucose level in acute heart failure (AHF) has not been sufficiently clarified. The data from 1234 AHF patients were examined in the present study. The blood glucose (BG) levels were evaluated at admission. The patients were divided into groups based on the following: with or without diabetes mellitus (DM), and BG level ≥ 200 mg/dl (elevated BG) or &lt
200 mg/dl (decreased BG). The elevated and decreased BG patients were further divided into another three groups: 200 mg/ml ≤ BG &lt
300 mg/dl (mild-elevated), 300 mg/ml ≤ BG &lt
400 mg/dl (moderate-elevated) and BG ≥ 400 mg/ml (severe-elevated)
and 150 mg/ml ≤ BG &lt
200 mg/dl (mild-decreased), 100 mg/ml ≤ BG &lt
150 mg/dl (moderate-decreased) and BG &lt
100 mg/ml (severe-decreased), respectively. The DM patients had a significantly poorer mortality than the non-DM patients. The prognosis was different between patients with elevated or decreased BG. In DM patients with elevated BG, the severe-elevated patients had a significantly poorer prognosis than moderate- and mild-elevated patients. In the DM patients with decreased BG, the severe-decreased patients had a significantly poorer prognosis than those moderate- and mild-decreased patients. The multivariate Cox regression model showed that a severe-decreased [hazard ratio (HR) 3.245, 95% confidence interval (CI) 1.271–8.282] and severe-elevated (HR 2.300, 95% CI 1.143–4.628) status were independent predictors of 365-day mortality in AHF patients with DM. The mortality was high among AHF patients with DM. Furthermore, both severe hyperglycemia and hypoglycemia were independent predictors of the mortality in patients with AHF complicated with DM.

The optimum method of managing anemia during the acute phase of acute heart failure (AHF) remains to be elucidated. The data from 1109 AHF patients were enrolled in present study. The hemoglobin (Hb) levels were evaluated in all patients at admission (day 1) and 3 days after admission (day 3), and in survival discharge patients (n = 998) before discharge (pre-discharge). The serum hemoglobin levels were significantly lower on day 3 (11.2 (9.6–12.9) g/dl) than on day 1 (12.4 (10.4–14.2) g/dl) and at pre-discharge (11.6 (10.1–13.2) g/dl). A multivariate Cox regression model showed that mild anemia (11.0 ≤ Hb ≤ 12.9 g/dl, n = 316) and severe anemia (Hb ≤ 10.9 g/dl, n = 517) on day 3 were independent predictors of HF event (hazard ratio (HR) 1.542, 95% confidence interval (CI)1.070–2.221, HR 2.026, 95% CI 1.439–2.853), and severe anemia on day 3 were independent predictors of 365-day mortality (HR 2.247, 95% CI 1.376–3.670). The prognosis, including all-cause death and HF events, in patients with non-anemia on day 1 was significantly poorer in severe new-anemia patients on day 3 (n = 44) than in mild new-anemia patients on day 3 (n = 153) and non-anemia patients on day 3 (n = 252). In patients with anemia on day 1, the prognosis was significantly poorer in patients with severe anemia on day 3 (n = 190) than in those with non-anemia or mild anemia on day 3 (n = 482). The hemoglobin level after the initial treatment might be easily influenced by clinical decongestion. Successfully treated decongestion can help maintain the hemoglobin levels. It, therefore, leads to a prognostic benefit in patients with AHF. These findings might underscore the importance of hemoglobin management of the acute phase of AHF.

Patients with heart failure (HF) are sometimes classified as malnourished, but the prognostic value of nutritional status in acute HF (AHF) remains largely unstudied. 1214 patients who were admitted to the intensive care unit between January 2000 and June 2016 were screened based on their serum albumin, lymphocyte count, and total cholesterol measures. A total of 458 HF patients were enrolled in this study. The Prognostic Nutritional Index (PNI) is calculated as 10 × serum albumin (g/dL) + 0.005 × lymphocyte count (per mm3) (lower = worse). The Controlling Nutritional Status (CONUT) score is points based, and is calculated using serum albumin, total cholesterol, and lymphocyte count (range 0–12, higher = worse). Patients were divided into three groups according to PNI: high-PNI (PNI &lt
 35, n = 331), middle-PNI (35 ≤ PNI &lt
 38, n = 50), and low-PNI (PNI ≥ 38, n = 77). They were also divided into four groups according to CONUT score: normal-CONUT (0–1, n = 128), mild-CONUT (2–4, n = 179), moderate-CONUT (5–8, n = 127), and severe-CONUT (≥9, n = 24). The PNI, which exhibited a good balance between sensitivity and specificity for predicting in-hospital mortality [66.1 and 68.4%, respectively
area under the curve (AUC) 0.716
95% confidence interval (CI) 0.638–0.793), was 39.7 overall, while the CONUT score was 5 overall (61.4 and 68.4%, respectively
AUC 0.697
95% CI 0.618–0.775). A Kaplan–Meier curve indicated that the prognosis, including all-cause death, was significantly (p &lt
 0.001) poorer in low-PNI patients than in high-PNI groups and was also significantly poorer in severe-CONUT patients than in normal-CONUT and mild-CONUT groups. A multivariate Cox regression model showed that the low-PNI and severe-CONUT categories were independent predictors of 365-day mortality [hazard ratio (HR) 2.060, 95% CI 1.302–3.259 and HR 2.238, 95% CI 1.050–4.772, respectively). Malnutrition, as assessed using both the PNI and the CONUT score, has a prognostic impact in patients with severely decompensated AHF.

Purpose: To investigate the 1-year outcomes of transvenous intravascular ultrasound (IVUS)-guided endovascular therapy (EVT) for chronic total occlusion (CTO) of the lower extremity arteries. Methods: Transvenous IVUS-guided EVT was performed in 44 patients (50 limbs) with CTO of the femoropopliteal arteries or tibioperoneal trunk. Treatment involved crossing a guidewire through the CTO under the guidance of both fluoroscopic and IVUS imaging, along with insertion of the IVUS catheter into a vein parallel to the target artery. Primary success rate, complications, and target lesion revascularization (TLR) at 12-month follow-up were investigated. Results: Successful recanalization, defined as grade 3 flow (Thrombolysis in Myocardial Infarction score) and no flow-limiting dissection, was observed in 48 (96%) limbs. Two limbs with failed recanalization had a very long CTO lesion from the superficial femoral artery to below the knee. A bidirectional approach was selected in 11 (22%) limbs. Complications at the access site occurred in only 2 patients. The rate of freedom from TLR at 12 months was 77.9% (95% confidence interval 61.4 to 87.9). Conclusion: Transvenous IVUS-guided EVT is safe and can provide optimal short-term results for EVT of CTO in the infrainguinal arteries. IVUS-guided EVT may be one of the most effective treatment strategies for CTO of the femoropopliteal arteries or tibioperoneal trunk.

Background: The gender differences in the prognosis of Asian patients with acute heart failure (AHF) remain to be elucidated.
Methods and results: One thousand fifty AHF patients were enrolled. The patients were assigned to a female group (n = 354) and a male group (n = 696). A Kaplan-Meier curve showed that the cardiovascular survival rate of the female group was significantly lower than that of the male group (p = 0.005). A multivariate Cox regression model identified female gender [hazard ratio (HR): 1.381, 95% CI: 1.018-1.872] as an independent predictor of 730-day cardiovascular death. In subgroup analysis by age, in patients over 79 years, female gender significantly increased the cardiovascular death (HR: 1.715, 95% CI: 1.088-2.074, p &lt; 0.001) with a significant interaction (p-value for interaction &lt; 0.001). The prognosis, including cardiovascular death, was significantly poorer among elderly female patients (&gt;= 79 years) than among elderly male patients (p = 0.019). The multivariate Cox regression model identified female gender as an independent predictor of 730-day cardiovascular death in patients who were older than 79 years of age (HR, 1.943; 95% CI, 1.192-3.167).
Conclusions: Female gender was associated with poor prognosis in AHF patients. In particular, old age (&gt;= 79 years) was associated with adverse outcomes in female patients with AHF. (C) 2016 Japanese College of Cardiology. Published by Elsevier Ltd. All rights reserved.

Obesity is known to be associated with the development of heart failure (HF). However, the relationship between the body mass index (BMI) and acute HF (AHF) remains to be elucidated. Eight hundred and eight AIIF patients were enrolled in this study. The patients were assigned to four groups according to their BMI values: severely thin (n = 11, BMI &lt;16), normal/underweight (n = 579, 16 = BMI &lt;25), overweight (n = 178, 25 = BMI &lt;30) and obese (n = 40, BMI = 30). The patients in the severely thin group were more likely to be female, have systolic blood pressure (SBP) &lt;100 mmHg and have valvular disease than normal/underweight patients. The patients in the overweight group were significantly younger than those in the normal/underweight, and those in the overweight group were more likely to have SBP = 140 mmHg and hypertensive heart disease and less likely to have valvular disease than the patients in the normal/underweight group. The prognosis, including all-cause death, was significantly poorer among patients who were severely thin than those who were normal/underweight, overweight and significantly better among those who were overweight than those who were normal/underweight, severely thin and obese patients. A multivariate Cox regression model identified that severely thin [HR: 3.372, 95% confidence interval (CI) 1.362-8.351] and overweight ( HR: 0.615, 95% CI 0.391-0.966) were independent predictors of 910-day mortality as the reference of normal/underweight. Overweight patients tended to have SBP &gt;= 140 mmHg and be relatively young, while severely thin patients tended to have SBP &lt;100 mmHg and be female. These factors were associated with a better prognosis of overweight patients and adverse outcomes in severely thin patients. These factors may contribute to the "obesity paradox" in severely decompensated AHF patients.

Atherosclerosis induces the elevation of uric acid (UA), and an elevated UA level is well known to lead to a poor prognosis in patients with acute heart failure (AHF). However, the prognostic value of atherosclerotic risk factors in hyperuricemic AHF patients remains to be elucidated. The data from 928 patients who were admitted to the intensive care unit (ICU) at Nippon Medical School Chiba Hokusoh Hospital between January 2001 and December 2014, and whose serum UA levels were measured were screened. A total of 394 AHF patients with hyperuricemia were enrolled in this study. The patients were assigned to a low-risk group (&lt;= 1 atherosclerosis risk factor) and a high-risk group (&gt;= 2 atherosclerosis risk factors) according to their number of risk factors. The patients in the low-risk group were more likely to have dilated cardiomyopathy, clinical scenario 3 than those in the high-risk group. The serum total bilirubin, blood urea nitrogen, C-reactive protein, and brain-type natriuretic peptide levels were significantly higher in the low-risk group than the high-risk group (p &lt; 0.001, p = 0.005, p = 0.003, and p = 0.008, respectively). A multivariate Cox regression model revealed that the number of risk factors (number = 1, HR (hazard ratio) 0.243, 95 % CI 0.096-0.618, p = 0.003; number = 2, HR 0.253, 95 % CI 0.108-0.593, p = 0.002; number &gt;= 3, HR 0.209, 95 % CI 0.093-0.472, p &lt; 0.001), eGFR (per 1.0 mmol/l increase) (HR 0.977, 95 % CI 0.961-0.994, p = 0.007), and serum UA level (per 1 mg/dl increase) (HR 1.270, 95 % CI 1.123-1.435, p &lt; 0.001) was an independent predictor of 1-year mortality. The prognosis, including all-cause death and HF events, was significantly poorer among the low-risk patients than among the high-risk patients. Atherosclerotic risk factors were not associated with a poor prognosis in patients with hyperuricemic AHF.

Background: The clinical significance of urinary liver fatty acid-binding protein (u-LFABP) in acute heart failure (AHF) patients remains unclear. Methods and Results: The u-LFABP levels on admission of 293 AHF patients were analyzed. The patients were divided into 2 groups according to the u-LFABP quartiles (Q1, Q2, and Q3 = low u-LFABP [L] group vs. Q4 = high u-LFABP [H] group). We evaluated the diagnostic and prognostic value of u-LFABP and compared the findings between the chronic kidney disease (CKD; n = 165) and non-CKD patients (n = 128). Acute kidney injury (AKI) during the first 7 days was evaluated based on the RIFLE criteria. In the non-CKD group, the number of AKI patients during the first 7 days was significantly greater in the H group (70.0%) than in the L group (45.6%). A multivariate logistic regression model indicated that the H group (odds ratio: 3.850, 95% confidence interval [CI] 1.128-13.140) was independently associated with AKI during the first 7 days. The sensitivity and specificity of u-LFABP for predicting AKI were 63.6 and 59.7% (area under the ROC curve 0.631) at 41.9 ng/mg x cre. A Cox regression model identified the H group (hazard ratio: 13.494, 95% CI 1.512-120.415) as an independent predictor of the 60-day mortality. A Kaplan-Meier curve, including all-cause death within 60 days, showed a significantly poorer survival rate in the H group than in the L group (p = 0.036). Conclusions: The u-LFABP level is an effective biomarker for predicting AKI during the first 7 days of hospitalization and an adverse outcome in AHF patients with non-CKD. (C) 2017 S.

複数血管の血管内視鏡検査により、BMIと冠動脈硬化度との関連性について検討した。2000年9月〜2007年7月に複数血管の血管内視鏡検査を施行した冠動脈疾患患者89例を、BMIに基づいて過小体重(<20kg/m2)群7例、正常体重(20〜25kg/m2)群40例、過体重(25〜28kg/m2)群27例、肥満(≧28kg/m2)群15例に分けた。観察した冠動脈で認められた黄色プラーク数(NYP)を数え、各プラークの色をグレード1(淡黄色)、グレード2(黄色)、グレード3(濃い黄色)と定義した。1血管あたりのNYPと最大黄色グレード(MYG)を4群間で比較した。その結果、冠動脈硬化度の重症度(NYP、MYG)は有意に異なっていた。多変量回帰分析により、BMIは1血管あたりのNYPと独立して相関していることが明らかになった。過小体重患者の冠動脈硬化は正常および過体重患者よりも進行しており、低BMIは進行性冠動脈硬化と独立して関連していることが示された。

Contrast media are considered to cause acute kidney injury by activating various factors that induce renal vasoconstriction. We analysed the renal microvascular haemodynamic response using the Doppler flow wire method. Then changes in urinary liver-type fatty acid-binding protein levels following contrast medium administration were compared between groups with or without a micro-injury of the kidney. In the group without renal micro-injury, the average peak velocity (APV) decreased significantly, whereas the renal artery resistance index (RI) increased significantly following contrast medium administration. In contrast, there was no significant change in either the APV or RI in the group with a renal micro-injury. A blunted microvascular response was found in the micro-injury group, whereas microvascular resistance increased in the non-micro-injury group.

Background: The serum level of uric acid (UA) is a well-known prognostic factor for heart failure (HF) patients. However, the prognostic impact of hyperuricemia and the factors that induce hyperuricemia in acute I-IF (AHF) patients are not well understood.
Methods and results: Eight hundred eighty-nine AHF patients were enrolled in this study. The patients were assigned into a low UA group (UA &lt;= 7.0 mg/dl, n = 495) or a high UA group (UA &gt; 7.0 mg/dl, n = 394) according to their UA level on admission. A Kaplan-Meier curve showed that the survival rate of the low UA group was significantly higher than that of the high UA group. A multivariate Cox regression model identified that a high UA level (HR: 1.192, 95%CI 1.112-1.277) was an independent predictor of 180-day mortality. A multivariate logistic regression model for a high serum UA level on admission indicated that chronic kidney disease (CKD) (OR: 2.030, 95%CI: 1.298-3.176, p = 0.002) and the administration of loop diuretics before admission (OR: 1.556, 95%Cl: 1.010-2.397, p = 0.045) were independent factors. The prognosis, including all-cause death and HF events, was significantly poorer among patients who had a high UA level who had previously used loop diuretics and among CKD patients with a high UA level than among other patients.
Conclusions: The serum UA level was an independent predictor in patients who were hospitalized during an emergent situation for AHF. An elevated serum UA level on admission was associated with the presence of CKD and the use of loop diuretics. These factors were also associated with adverse outcomes in hyperuricemic patients with AHF. (C) 2016 Japanese College of Cardiology. Published by Elsevier Ltd. All rights reserved.

Acute coronary syndrome (ACS) could be a precious opportunity for patients to reveal concealed diseases other than conventional risk factors for ACS, such as hypertension, dyslipidemia, diabetes mellitus, etc. In the setting of ACS, the intracoronary and systemic prothrombotic environment has led to an increase in the risk of stent thrombosis of which mortality was higher among patients with ACS, especially with the highest mortality in patients with ST elevation myocardial infarction. The some specific conditions which were concealed beyond the cardiovascular pathophysiology except well-known risk factors for ACS and stent thrombosis might involve the onset of ACS. We describe a case of a 64-year-old man who was admitted to intensive care unit for chest pain. This case found the possibility that polycythemia vera with Janus kinase 2 (JAK2) V617F mutation might be a underlying disease of ACS with stent thrombosis, and highlighted the importance of recognizing polycythemia vera with JAK2 V617F mutation as concealed disease for cardiologists. We would like to report and review the relationship between ACS and polycythemia vera with JAK2 V617F mutation.

Although an association has been reported between the microvascular complications of diabetic patients and their poor prognosis after cardiovascular events related to advanced atherosclerosis, it is not clear whether there is a relation between diabetic retinopathy (DR) and the severity of plaque vulnerability. Fifty-seven diabetic patients with coronary artery disease, classified as non-DR (n = 42) or DR (n = 15), underwent angioscopic observation of at least 1 entire coronary artery. The number of yellow plaques (NYP) through the observed coronary artery was counted and their color grades, defined as 1 (light yellow), 2 (yellow), or 3 (intense yellow), were evaluated. The NYP per vessel and the maximum yellow grade were determined. The association between the presence of DR and incidences of acute coronary syndrome (ACS) was analyzed during the follow-up period (mean 7.1 +/- 3.3 years; range, 0.83 to 11.75 years). Mean NYP per vessel and maximum yellow grade were significantly greater in DR than in non-DR patients (2.08 +/- 1.01 vs 1.26 +/- 0.77, p = 0.002, and 2.40 +/- 0.74 vs 1.90 +/- 0.82, p = 0.044, respectively). The cumulative incidences of ACS were higher in the DR group (p = 0.004), and the age-adjusted hazard ratio for ACS was 6.943 (95% CI 1.267 to 38.054; p = 0.026) for DR compared with non DR patients. Our findings indicate that coronary atherosclerosis and plaque vulnerability are more severe in patients with DR. DR as a microvascular complication may be directly linked with macrovascular plaque vulnerability and fatal cardiovascular events such as ACS. (C) 2016 Elsevier Inc. All rights reserved.

Background: No cardiac biomarkers for detecting acute kidney injury (AKI) on admission in non-surgical intensive care patients have been reported. The aim of the present study is to elucidate the role of cardiac biomarkers for quickly identifying the presence of AKI on admission.
Methods: Data for 1183 patients who underwent the measurement of cardiac biomarkers, including the serum heart-type fatty acid-binding protein (s-HFABP) level, in the emergency department were screened, and 494 nonsurgical intensive care patients were enrolled in this study. Based on the RIFLE classification, which was the ratio of the serum creatinine value recorded on admission to the baseline creatinine value, the patients were assigned to a no-AKI (n = 349) or AKI (Class R [n = 83], Class I [n = 36] and Class F [n = 26]) group on admission. We evaluated the diagnostic value of the s-H-FABP level for detecting AKI and Class I/F. The mid-term prognosis, as all-cause death within 180 days, was also evaluated.
Results: The s-H-FABP levels were significantly higher in the Class F (79.2 [29.9 to 200.3] ng/mL) than in the Class I (41.5 [16.7 to 71.6] ng/mL), the Class R (21.1 [10.2 to 47.9] ng/mL), and no-AKI patients (8.8 [5.4 to 17.7] ng/mL). The most predictive values for detecting AKI were Q2 (odds ratio [OR]: 3.743; 95 % confidence interval [CI]: 1.693-8.274), Q3 (OR: 9.427; 95 % CI: 4.124-21.548), and Q4 (OR: 28.000; 95 % CI: 11.245-69.720), while those for Class I/F were Q3 (OR: 5.155; 95 % CI: 1.030-25.790) and Q4 (OR: 22.978; 95 % CI: 4.814-109.668). The s-HFABP level demonstrating an optimal balance between sensitivity and specificity (70.3 and 72.8 %, respectively; area under the curve: 0.774; 95 % CI: 0.728-0.819) was 15.7 ng/mL for AKI and 20.7 ng/mL for Class I/F (71.0 and 83.1 %, respectively; area under the curve: 0.818; 95 % CI: 0.763-0.873). The prognosis was significantly poorer in the high serum HFABP with AKI group than in the other groups.
Conclusions: The s-H-FABP level is an effective biomarker for detecting AKI in non-surgical intensive care patients.

Contrast-induced nephropathy (CIN) is considered to result from intrarenal vasoconstriction, and occurs more frequently in impaired than in normal kidneys. It was hypothesized that iodinated contrast media would markedly change renal blood flow and vascular resistance in functionally impaired kidneys. Thirty-six patients were enrolled (32 men
mean age, 75.3 ± 7.6 years) undergoing diagnostic coronary angiography and were divided into two groups based on the presence of chronic kidney disease (CKD), defined as an estimated glomerular filtration rate (eGFR) of &lt
60 mL/min per 1.73 m2 (CKD and non-CKD groups, n = 18 in both). Average peak velocity (APV) and renal artery resistance index (RI) were measured by Doppler flow wire before and after administration of the iodinated contrast media.

0.001) and RI (P = 0.002) were significantly changed following contrast media administration in the non-CKD group, but not in the CKD group (APV, P = 0.258
RI, P = 0.707). Although renal arterial resistance was higher in patients with CKD, it was not affected by contrast media administration, suggesting that patients with CKD could have an attenuated response to contrast media.

Contrast-induced nephropathy (CIN) is considered to result from intrarenal vasoconstriction, and occurs more frequently in impaired than in normal kidneys. It was hypothesized that iodinated contrast media would markedly change renal blood flow and vascular resistance in functionally impaired kidneys. Thirty-six patients were enrolled (32 men; mean age, 75.3 +/- 7.6 years) undergoing diagnostic coronary angiography and were divided into two groups based on the presence of chronic kidney disease (CKD), defined as an estimated glomerular filtration rate (eGFR) of &lt; 60 mL/min per 1.73 m(2) (CKD and non-CKD groups, n = 18 in both). Average peak velocity (APV) and renal artery resistance index (RI) were measured by Doppler flow wire before and after administration of the iodinated contrast media. The APV and the RI were positively and inversely correlated with the eGFR at baseline, respectively (APV, R = 0.545, P = 0.001; RI, R = -0.627, P &lt; 0.001). Mean RI was significantly higher (P = 0.015) and APV was significantly lower (P = 0.026) in the CKD than in the non-CKD group. Both APV (P &lt; 0.001) and RI (P = 0.002) were significantly changed following contrast media administration in the non-CKD group, but not in the CKD group (APV, P = 0.258; RI, P = 0.707). Although renal arterial resistance was higher in patients with CKD, it was not affected by contrast media administration, suggesting that patients with CKD could have an attenuated response to contrast media.

There have been few reports discussing the clinical significance of the season of admission of acute heart failure (AHF) patients. The data of 661 patients with AHF admitted to the intensive care unit were analyzed. Patients were assigned to a summer admission (Group-S, n = 113, between July and September), a winter admission (Group-W, n = 214, between December and February), or to the other seasons admission group (Group-O, n = 334). We evaluated the relationships between the seasonal variations and the clinical profiles, and the long-term prognosis. There were significantly more patients with cardiomyopathy and New York Heart Association class 4, and the serum levels of total bilirubin were significantly higher in Group-S (85.8, 24.8 %, and 0.60 [0.50-0.90]) than in Group-W (75.2, 15.4 %, and 0.60 [0.40-0.78]). The left ventricular ejection fraction on admission was significantly reduced and intravenous administration of dobutamine was used more frequently in Group-S (30.0 [25.0-46.0], 31.9 %) than in Group-W (34.4 [25.2-48.0], 20.6 %) and Group-O (35.0 [25.0-46.0], 19.8 %). The multivariate Cox regression model found that summer admission was independently associated with cardiovascular death (HR: 1.58, 95 % CI 1.01-2.48; p = 0.044) and heart failure (HF) events (HR: 1.55, 95 % CI 1.05-2.28; p = 0.028). The Kaplan-Meier curves showed that the cardiovascular death rate was significantly higher in Group-S than in Group-W and Group-O, and the HF events were significantly higher in Group-S than in Group-O. The summer admission AHF patients included sicker patients, and the prognosis in these patients was worse than in the patients admitted at other times.

Background: Different mechanisms of acute kidney injury (AKI) may exist for acute heart failure (AHF) patients compared with other patients.
Methods and Results: We analyzed data from 282 patients with AHF. The biomarkers were measured within 30 min of admission. Patients were assigned to a no-AKI (n=213) or AKI group (Class R (n=49), Class I (n=15) or Class F (n=5)) using the RIFLE classifications on admission. We evaluated the relationships between the biomarkers and AKI, in-hospital mortality, all-cause death and HF events (HF re-admission, all-cause death) within 90 days. The serum heart-type fatty acid-binding protein (s-HFABP) levels were significantly higher in the AKI than in the no-AKI group, and the predictive biomarker for AKI was s-HFABP (odds ratio: 6.709; 95% confidence interval: 3.362-13.391). s-HFABP demonstrated an optimal balance between sensitivity and specificity (71.0%, 79.3%; area under the receiver-operating characteristic curve [AUC]=0.790) at 22.8 ng/ml for AKI, at 22.8 ng/ml for Class I/F (90.0%, 71.4%; AUC=0.836) and at 21.0 ng/ml for in-hospital mortality (74.3%, 70.0%; AUC=0.726). The Kaplan-Meier survival curves showed a significantly poorer prognosis in the high s-HFABP group (&gt;= 22.9 ng/ml) than in other groups.
Conclusions: The s-HFABP level can indicate AKI on admission, and a high s-HFABP level is associated with a poorer prognosis for AHF patients.

Background: No scoring system for assessing acute heart failure (AHF) has been reported.
Methods and results: Data for 824 AHF patients were analyzed. The subjects were divided into an alive (n =750) and a dead group (n= 74). We constructed a predictive scoring system based on eight significant APACHE II factors in the alive group [mean arterial pressure (MAP), pulse, sodium, potassium, hematocrit, creatinine, age, and Glasgow Coma Scale (GCS); giving each one point], defined as the APACHE-HF score. The patients were assigned to five groups by the APACHE-HF score [Group 1: point 0 (n = 70), Group 2: points 1 and 2 (n =343), Group 3: points 3 and 4 (n =294), Group 4: points 5 and 6 (n =106), and Group 5: points 7 and 8 (n =11)]. A higher optimal balance was observed in the APACHE-HF between sensitivity and specificity [87.8%, 63.9%; area under the curve (AUC)= 0.779] at 2.5 points than in the APACHE II (47.3%, 67.3%; AUC= 0.558) at 17.5 points. The multivariate Cox regression model identified belonging to Group 5 [hazard ratio (HR): 7.764, 95% confidence interval (CI) 1.586-38.009], Group 4 (HR: 6.903, 95%CI 1.940-24.568) or Group 3 (HR: 5.335, 95%CI 1.582-17.994) to be an independent predictor of 3-year mortality. The Kaplan-Meier curves revealed a poorer prognosis, including all-cause death and HE events (death, readmission-HE), in Group 5 and Group 4 than in the other groups, in Group 3 than in Group 2 or Group 1, and in Group 2 than in Group 1.
Conclusions: The new scoring system including MAP, pulse, sodium, potassium, hematocrit, creatinine, age, and GCS (APACHE-HF) can be used to predict adverse outcomes of AHF. (C) 2014 Japanese College of Cardiology. Published by Elsevier Ltd. All rights reserved.

Biomarkers predicting adverse outcomes in non-surgical intensive care patients have not been reported.
Data for 1,006 emergency department patients were prospectively analyzed. The serum heart-type fatty acid-binding protein (s-H-FABP) level was measured within 10 min of admission. The patients were assigned to intensive care (n = 835) or other departments (n = 171). The intensive care patients were divided into survivors (n = 745) and non-survivors (n = 90) according to the in-hospital mortality and assigned to four groups according to the quartiles of s-H-FABP (Q1, Q2, Q3 and Q4). The s-H-FABP levels were significantly higher in the intensive care patients (12.7 [6.1-38.8] ng/ml versus 5.3 [3.1-9.4] ng/ml) and in the non-survivors (44.9 [23.2-87.6] ng/ml versus 11.5 [5.6-32.6] ng/ml). A Kaplan-Meier curve showed a significantly higher survival rate in Q3 than in Q1 and Q2 and in Q4 than in the other groups. The multivariate Cox regression model identified Q3 (HR 4.646, 95 % CI 1.526-14.146) and Q4 (HR 9.483, 95 % CI 3.152-28.525) as independent predictors of 90-day mortality. The sensitivity and specificity of H-FABP for in-hospital mortality were 81.1 and 66.0 % (AUC 0.775) at 20.95 ng/ml. The in-hospitality rate was significantly higher in the high s-H-FABP patients than in the low s-H-FABP patients in each etiology group.
The s-H-FABP level is an effective biomarker for risk stratification in non-surgical intensive care patients.

Background: Tolvaptan, an oral selective vasopressin 2 receptor antagonist that acts on the distal nephrons to cause a loss of electrolyte-free water, is rarely used during the acute phase of acute heart failure (AHF).
Methods and Results: We investigated 183 AHF patients admitted to the intensive care unit and administered tolvaptan (7.5 mg) with continuous intravenous furosemide, and then additionally at 12-h intervals until HF was compensated. When intravenous furosemide was changed to peroral use, the administration of tolvaptan was stopped. The patients were assigned to tolvaptan (n=52) or conventional treatment (n=131) groups. The amount of intravenous furosemide was significantly lower (35.4 [16.3-56.0] mg vs. 80.0 [30.4-220.0] mg), the urine volume was significantly higher on days 1 and 2(3,691 [3,109-4,198] ml and 2,953 [2,128-3,592] ml vs. 2,270 [1,535-3,258] ml and 2,129 [1,407-2,906] ml) and the numbers of patients with worsening-AKI (step-up RIFLE Class to I or F) and Class F were significantly fewer (5.8% and 1.9% vs. 19.1% and 16.0%) in the tolvaptan group than in the conventional group, respectively. One of the specific medications indicated worsening-AKI and in-hospital mortality was tolvaptan (odds ratio [OR] 0.155, 95% confidence interval [CI] 0.037-0.657 and OR 0.191, 95% CI 0.037-0.985). The Kaplan-Meier curves showed that the death rate within 6 months was significantly lower in the tolvaptan group. The same result was found after propensity matching of the data.
Conclusions: Early administration of tolvaptan could prevent exacerbation of AKI and improve the prognosis for AHF patients.

Background: The predictive factors for survival after percutaneous cardiopulmonary support (PCPS) are unknown.
Methods and Results: Data for 105 patients with cardiovascular disease requiring PCPS were analyzed. The patients were divided into a survivor (n=21) or a non-survivor group (n=84). The age was significantly lower, and there were more patients with fulminant myocarditis and PCPS attempted before cardiac arrest (CA) in the survivor group. Additionally, there were fewer cases of out-of-hospital CA, and the mean time from CA to PCPS was shorter in the survivor group. On multivariate logistic regression it was found that the age and the time from CA to PCPS were independently associated with survival. A predictive scoring system was constructed that included the following: (1) age &lt;50 years; (2) diagnosis of fulminant myocarditis; (3) no out-of-hospital CA; (4) PCPS attempted before CA; and (5) time from CA to PCPS &lt;45 min. The predictive score was significantly higher in the survivor than in the non-survivor group (2.33+/-1.32 vs. 1.06+/-1.02). The sensitivity and specificity for survival were 85.7% and 66.7% when the score was &gt;= 2. Kaplan-Meier survival analysis showed that any-cause death was significantly higher in patients with PCPS survival score &lt;= 1 than in those with a score &gt;= 2.
Conclusions: PCPS survival score is suitable for clinically predicting survival in patients with cardiovascular disease undergoing PCPS.

Aim of the Study: Cardiopulmonary resuscitation and mild therapeutic hypothermia (MTH) have improved neurological outcomes after sudden cardiac arrest, but the factors affecting favorable neurological outcome remain unclear. The aim of this study was to clarify these factors in patients in cardiac arrest treated with MTH.
Methods: Forty-six consecutive patients (mean age, 59.4 +/- 14.3 years; 37 men and 9 women) who had had cardiogenic cardiac arrest from January 2008 through December 2011, including cases that were and were not shockable, were enrolled in this study, and the factors affecting favorable neurological outcome were retrospectively investigated. The interval from cardiac arrest to cardiopulmonary resuscitation, the return of spontaneous circulation (ROSC), the start of MTH, and the attaining of the target temperature were retrieved from the medical records. The relationship between the neurological outcome and clinical findings, including the causes of cardiac arrest and vital signs before MTH, were also investigated.
Results: Blood pressure and body temperature before MTH were higher, the interval from cardiac arrest to ROSC was shorter, and MTH was started earlier in patients with favorable neurological outcomes than in those with unfavorable outcomes. A multivariate logistic regression model revealed that the presence of prehospital ROSC was predictive of a favorable neurological outcome. In addition, renal failure during MTH occurred more frequently in patients with unfavorable neurological outcomes.
Conclusion: MTH is associated with favorable neurological outcomes after sudden cardiac arrest, including those with non-shockable rhythms, especially in patients with prehospital ROSC.

Aim. The aim of this study is to clarify the clinical significance of acute kidney injury (AKI), evaluated by standard method, in patients with non-surgical type-B acute aortic dissection (AAD). Methods. AKI was evaluated by using the RIFLE (Risk, Injury, Failure, Loss of kidney function and End-stage kidney disease) classification in 94 non-surgical type-B AAD patients. The incidence of AKI during hospitalization, factors associated with the occurrence of AKI, and relationships between AKI and outcomes were analyzed retrospectively. Results. AKI occurred in 59 (62.8%) during hospitalization on hospital day 4.6±5.4. The occurrence of AKI was associated with maximum C-reactive protein, white blood cell count, prolongation of high body temperature, and visceral ischemia including the kidney and the gastrointestinal tract. AKI frequently occurred in non-surgical type-B AAD patients, and it was associated with renal circulation and inflammatory reactions. The renal function recovered in 44% of AKI patients during hospitalization, especially in those without chronic renal insufficiency. The duration of both the stay in the ICU stay and hospital were longer in patients with severe AKI (class F category of AKI) than others. Conclusion. AKI frequently occurred in non-surgical type-B AAD, and it was associated with renal circulation, inflammatory reactions, and poor outcome. And the renal function recovered in 44% of AKI patients during hospitalization, especially in those without chronic renal insufficiency.

Background: There have been few reports about the clinical significance of the time of admission for acute heart failure (AHF). Methods: Five hundred thirty-one patients with AHF admitted to the intensive care unit (ICU) were analyzed. The patients were assigned to either the daytime HF group (n=195, visited from 08:00 to 20:00, Group D) or nighttime HF group (n=336, visited from 20:00 to 08:00, Group N). The clinical findings and outcomes were compared between these groups. Results: The systolic blood pressure (SBP), the number of patients with clinical scenario (CS) 1, and the heart rate (HR) were significantly higher in group N (SBP, 171.0 ± 38.9. mmHg
CS 1, 80.9%
HR, 116.9 ± 28.0. beats/min) than in group D (SBP, 154.2 ± 37.1. mmHg
CS 1, 66.2%
HR, 108.6 ± 31.4. beats/min). The patients in group N were more likely to have orthopnea (91.1%) than those in group D (70.3%). A multivariate logistic regression model identified a SBP ≥164. mmHg [odds ratio (OR): 2.043
95% confidence interval (CI): 1.383-3.109], HR ≥114. beats/min (OR: 1.490
95%CI: 1.001-2.218), and orthopnea (OR: 2.257
95%CI: 1.377-3.701) to be independently associated with Group N. The length of ICU stay was shorter in group N (5.8 ± 10.5 days) than in group D (7.8 ± 11.5 days). Conclusion: The nighttime HF was characterized by high SBP, high HR, and orthopnea, and the length of ICU stay was shorter in the nighttime HF group. © 2012 Japanese College of Cardiology.

Background: The relationship between acute kidney injury (AKI) in the acute phase of acute decompensated heart failure (ADHF) and patient outcome has not yet been reported.
Methods and Results: Data for 625 patients with ADHF admitted to the intensive care unit were analyzed. No AKI occurred in 281 patients (no AKI) during the first 5 days. The AKI patients were assigned to 3 groups based on the timing: AKI present on admission and stable risk, injury, failure, loss, and endstage (RIFLE) class (stable early AKI; n=125), stepped-up RIFLE class (worsening early AKI; n=49), or AKI that occurred after admission (late AKI; n=170). The AKI patients were grouped into another 3 groups based on severity: class R (risk; n=214), class I (injury; n=73), or class F (failure; n=57). A multivariate logistic regression model found class I, class F, late AKI and worsening early AKI to be independently associated with in-hospital mortality. Kaplan-Meier survival curves showed that the survival rate in any-cause death during 2 years was significantly lower in class I, class F and the worsening early-AKI group, and there were significantly more HF events in class F and the worsening early-AKI group. There were significantly more class I and class F patients in the worsening early-AKI group.
Conclusions: The presence of AKI on admission, worsening of AKI, and severe AKI (class I or class F) are associated with a poorer prognosis for ADHF patients. (Circ J 2013; 77: 687-696)

Background and purpose: The role of an arterial blood gas analysis in acute heart failure (AHF) remains unclear. The acid-base balance could help to treat AHF, and it might help to distinguish different types of AHF, while it might be associated with the AHF prognosis. The present study was conducted to determine the relationship between the arterial blood gas sample at the time of hospital admission and clinical findings on admission, outcomes.
Methods and results: Six hundred twenty-one patients with AHF admitted to the intensive care unit were analyzed. Patients were assigned to an alkalosis group (n = 99, pH &gt; 7.45), normal group (n = 178, 7.35 &lt;= pH &lt;= 7.45), and acidosis group (n = 344, pH &lt; 7.35). The clinical findings on admission and outcomes (in-hospital mortality and any-cause death within 2 years) were compared between the three groups. The white blood cell counts (WBC), serum levels of total protein, albumin, and glucose were significantly lower, and the serum levels of C-reactive protein (CRP) and total bilirubin were significantly higher in the alkalosis group. Patients with orthopnea were significantly fewer, and the systolic blood pressure (SBP) and heart rate (HR) were significantly lower in the alkalosis group. The results of a multivariate logistic regression model for in-hospital mortality found that alkalosis was an independent risk factor (p = 0.017, odds ratio: 2.589; 95% confidence interval: 1.186-5.648). The Kaplan-Meier curves showed the prognosis for any-cause death to be significantly poorer in the alkalosis group than in the normal group (p = 0.026).
Conclusions: The factors associated with alkalosis AHF were high CRP, bilirubin, and low WBC, glucose, total protein, and albumin. The patients with alkalosis AHF were less likely to have orthopnea with low SBP and HR. They suggested that the patients with alkalosis AHF might have experienced AHF for a few days and were associated with high mortality. (C) 2012 Japanese College of Cardiology.

The relationship between the short-term prognosis of acute heart failure (AHF) and acute kidney injury (AKI) using the risk, injury, failure, and end stage (RIFLE) criteria has already been reported, however, the relationship between the long-term prognosis and AKI has not. We investigated the relationship between the long-term prognosis after discharge and AKI using the RIFLE criteria. Five hundred patients with AHF admitted to our intensive care unit were analyzed. Patients were assigned to a no AKI (n = 156), Class R (risk; n = 201), Class I (injury; n = 73), or Class F (failure; n = 70) using the most severe RIFLE classifications during hospitalization. We evaluated the relationships between the RIFLE classifications and any-cause death, and HF events including death and readmission for I-IF within I year. A multivariate logistic regression model found that Class I (P = 0.013, OR: 2.768; 95% CI: 1.236-6.199) and Class F (P &lt; 0.001, OR: 7.920; 95% CI: 3.497-17.938) were independently associated with any-cause death, and Class F was associated with HF events (P = 0.001, OR: 3.486; 95% CI: 1.669-7.281). The Kaplan-Meier survival curves showed the prognosis, including death, to be significantly poorer in Class I than in no AKI and Class R, to be significantly poorer in Class F than in no AM, Class R, and Class I, and the prognosis including HF events to be significantly poorer in Class F than in no AKI, Class R, and Class I. The presence of severe AKI (Class I and F) was independently associated with long-term mortality for AHF. (lilt Heart J 2012; 53: 313-319)

Background and purpose: We have reported that matrix metalloproteinase-2 (MMP-2) increased in acute heart failure (AHF) and better prognosis was found in patients with greater reduction in MMP-2. We assessed whether a statin decreased MMP-2 in AHF.
Methods and results: The serum MMP-2 levels were measured on admission (Day 1), Day 3, Day 7, and Day 14 in 50 AHF patients. The patients were randomized to either atorvastatin (n=25) or control group (n=25). Atorvastatin (10-20 mg/day) was started within 12h after their admission and then was continued for two weeks. There were no differences in the serum levels of MMP-2 on Day 1 between atorvastatin group (1400.4 +/- 318.6 ng/ml) and control group (1292.7 +/- 384.7 ng/ml). MMP-2 significantly decreased in both groups on Day 3, 7, and 14. However, the MMP-2 value on Day 3 compared to Day 1 was observed to have decreased significantly in atorvastatin group (561.8 +/- 235.1 ng/ml) compared to control group (272.6 +/- 270.6 ng/ml; p = 0.001). HF events which were defined as death from HF, readmission to hospital for HE or prolonged hospital stay because of uncontrollable HF, occurred more in control group than in atorvastatin group. Kaplan-Meier curves showed that the prognosis of HF was significantly better in atorvastatin group as compared with control group (log-rank test, p = 0.037).
Conclusion: In addition to conventional HF therapy, an early start of atorvastatin caused a great decrease in MMP-2 and also improved HF events in AHF. (C) 2012 Japanese College of Cardiology. Published by Elsevier Ltd. All rights reserved.
