    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.

    BACKGROUND: An inter-arm difference in blood pressure (IADBP) is characteristic of acute aortic dissection (AAD), but the importance of which arm exhibits lower blood pressure (BP) and the mechanism underlying IADBP are not well understood. METHODS: We identified consecutive patients with chest and/or back pain and suspected acute cardiovascular disease whose BP had been measured in both arms. We retrospectively compared the characteristics of such patients with AAD (n=93) to those without AAD (non-AAD group, n=122). Additionally, we separately compared patients with type A AAD (TAAD group, n=58) or type B AAD (TBAD group, n=35) to the non-AAD group. The characteristics analyzed were patient background and IADBP-related factors, including systolic BP (SBP) in the right arm (R) and left arm (L), and R-L or L-R as IADBP. Computed tomography (CT) findings of AD extending to the brachiocephalic artery (BCA) and/or left subclavian artery (LSCA) were examined in patients with an IADBP. RESULTS: In a comparison of the TAAD group and non-AAD group, the prevalences of R <130 mm Hg (38% vs. 19%, p=0.009), L-R >15 mm Hg (19% vs. 8%, p=0.047), L-R >20 mm Hg (14% vs. 4%, p=0.029) were higher in the TAAD group. Multivariate analysis showed that L-R >15 mm Hg with R <130 mm Hg was independently associated with TAAD (OR 25.97, 95% CI 2.45-275.67, p=0.007). However, IADBP-related factors were not associated with TBAD. AAD patients with L-R >20 mm Hg all had TAAD, and all aortic dissection extended to the BCA just before the right common carotid artery on CT. CONCLUSIONS: IADBP was characterized by R<L with low R in TAAD but was not associated with TBAD.
