AIM: To investigate the factors associated with favourable neurological outcomes in adult patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR) for out-of-hospital cardiac arrest (OHCA). METHODS: This retrospective observational study used secondary analysis of the SAVE-J II multicentre registry data from 36 institutions in Japan. Between 2013 and 2018, 2157 patients with OHCA who underwent ECPR were enrolled in SAVE-J II. A total of 1823 patients met the study inclusion criteria. Adult patients (aged ≥ 18 years) with OHCA, who underwent ECPR before admission to the intensive care unit, were included in our secondary analysis. The primary outcome was a favourable neurological outcome at hospital discharge, defined as a Cerebral Performance Category score of 1 or 2. We used a multivariate logistic regression model to examine the association between factors measured at the incident scene or upon hospital arrival and favourable neurological outcomes. RESULTS: Multivariable analysis revealed that shockable rhythm at the scene [odds ratio (OR); 2.11; 95% confidence interval (CI), 1.16-3.95] and upon hospital arrival (OR 2.59; 95% CI 1.60-4.30), bystander CPR (OR 1.63; 95% CI 1.03-1.88), body movement during resuscitation (OR 7.10; 95% CI 1.79-32.90), gasping (OR 4.33; 95% CI 2.57-7.28), pupillary reflex on arrival (OR 2.93; 95% CI 1.73-4.95), and male sex (OR 0.43; 95% CI 0.24-0.75) significantly correlated with neurological outcomes. CONCLUSIONS: Shockable rhythm, bystander CPR, body movement during resuscitation, gasping, pupillary reflex, and sex were associated with favourable neurological outcomes in patients with OHCA treated with ECPR.

Cardiogenic shock is a complex and diverse pathological condition characterized by reduced myocardial contractility. The goal of treatment of cardiogenic shock is to improve abnormal hemodynamics and maintain adequate tissue perfusion in organs. If hypotension and insufficient tissue perfusion persist despite initial therapy, temporary mechanical circulatory support (t-MCS) should be initiated. This decade sees the beginning of a new era of cardiogenic shock management using t-MCS through the accumulated experience with use of intra-aortic balloon pump (IABP) and venoarterial extracorporeal membrane oxygenation (VA-ECMO), as well as new revolutionary devices or systems such as transvalvular axial flow pump (Impella) and a combination of VA-ECMO and Impella (ECPELLA) based on the knowledge of circulatory physiology. In this transitional period, we outline the approach to the management of cardiogenic shock by t-MCS. The management strategy involves carefully selecting one or a combination of the t-MCS devices, taking into account the characteristics of each device and the specific pathological condition. This selection is guided by monitoring of hemodynamics, classification of shock stage, risk stratification, and coordinated management by the multidisciplinary shock team.

BACKGROUND: A better understanding of the relative contributions of various factors to patient outcomes is essential for optimal patient selection for extracorporeal cardiopulmonary resuscitation (ECPR) therapy for patients with out-of-hospital cardiac arrest (OHCA). However, evidence on the prognostic comparison based on the etiologies of cardiac arrest is limited. RESEARCH QUESTION: What is the etiology-based prognosis of patients undergoing ECPR for OHCA? STUDY DESIGN AND METHODS: This retrospective multicenter registry study involved 36 institutions in Japan and included all adult patients with OHCA who underwent ECPR between January 2013 and December 2018. The primary etiology for OHCA was determined retrospectively from all hospital-based data at each institution. We performed a multivariable logistic regression model to determine the association between etiology of cardiac arrest and two outcomes: favorable neurological outcomes and survival at hospital discharge. RESULTS: We identified 1,781 eligible patients, of whom 1,405 (78.9%) had cardiac arrest due to the cardiac causes. Multivariable logistic regression analysis for favorable neurological outcomes showed that accidental hypothermia (adjusted OR = 5.12; 95% CI = 2.98-8.80, P < 0.001) was associated with a significantly higher rate of favorable neurological outcomes than cardiac causes. Multivariable logistic regression analysis for survival showed that accidental hypothermia (adjusted OR = 5.19; 95% CI = 3.15-8.56, P < 0.001) had significantly higher rates of survival than cardiac causes. Acute aortic dissection/aneurysm (adjusted OR = 0.07, 95% CI = 0.02-0.28, P < 0.001) and primary cerebral disorders (adjusted OR = 0.12, 95% CI = 0.03-0.50, P = 0.004) had significantly lower rates of survival than cardiac causes. INTERPRETATION: In this retrospective multicenter cohort study, although most OHCA patients underwent ECPR for cardiac causes, accidental hypothermia was associated with favorable neurological outcomes and survival; in contrast, acute aortic dissection/aneurysm and primary cerebral disorders were associated with non-survival than cardiac causes.

Little is known about the impact of the downgrade of guideline recommendations for intra-aortic balloon pump (IABP) use and the approval of the Impella in Japan, where IABPs have been predominantly used. This study aimed to describe the annual trends in the mechanical circulatory support (MCS) use and outcomes in patients with cardiogenic shock (CS) requiring MCS. Using the Japanese Diagnosis Procedure Combination database from July 2010 to March 2021, we identified inpatients with CS requiring MCS. The patients were stratified into 3 groups: (1) IABP alone, (2) Impella alone, and (3) extracorporeal membrane oxygenation (ECMO), regardless of IABP or Impella use. The patient characteristics and outcomes were reported by the fiscal year. Of the 160,559 eligible patients, 117,599 (73.2%) used IABP alone, 1,465 (0.9%) Impella alone, and 41,495 (25.8%) ECMO. The prevalence of the use of an IABP alone significantly decreased from 80.5% in 2010 to 65.3% in 2020 (p for trend <0.001), whereas the prevalence of the use of an Impella alone significantly increased from 0.0% to 5.0% and ECMO from 19.5% to 29.6% (p for trend <0.001 for both). In-hospital mortality significantly increased from 29.3% in 2010 to 32.6% in 2020 in the overall patients with CS requiring MCS but significantly decreased in those requiring ECMO from 73.7% to 64.1% (p for trend <0.001 for both). In conclusion, there were significant annual changes in the patterns of MCS use and clinical outcomes in patients with CS requiring MCS.

Patients with acute myocardial infarction (AMI) triaged as life-threatening are transferred to our emergency medical care center (EMCC). However, data on these patients remain limited. We aimed to compare the characteristics and AMI prognosis of patients transferred to our EMCC with those transferred to our cardiovascular intensive care unit (CICU) using whole and propensity-matched cohorts.We analyzed the data of 256 consecutive AMI patients transferred from the scene to our hospital by ambulance between 2014 and 2017. The EMCC and CICU groups comprised 77 and 179 patients, respectively. There were no significant between-group age or sex differences. Patients in the EMCC group had more disease severity score and had the left main trunk identified as the culprit more frequently (12% versus 0.6%, P < 0.001) than those in the CICU group; however, the number of patients with multiple culprit vessels did not differ. The EMCC group had a longer door-to-reperfusion time (75 [60, 109] minutes versus 60 [40, 86] minutes, P< 0.001) and a higher in-hospital mortality (19% versus 4.5%, P < 0.001), especially from non-cardiac causes (10% versus 0.6%, P < 0.001), than the CICU group. However, peak myocardial creatine phosphokinase did not significantly differ between the groups. The EMCC group had a significantly higher 1-year post-discharge mortality than the CICU group (log-rank, P = 0.032); this trend was maintained after propensity score matching, although the difference was not statistically significant (log-rank, P = 0.094).AMI patients transferred to the EMCC exhibited more severe disease and worse overall in-hospital and non-cardiac mortality than those transferred to the CICU.

Although the primary percutaneous coronary intervention (PCI) is an established treatment for acute ST-elevation myocardial infarction (STEMI), relevant guidelines do not recommend it for recent-STEMI cases with a totally occluded infarcted related artery (IRA). However, PCI is allowed in Japan for recent-STEMI cases, but little is known regarding its outcomes. We aimed to examine the details and outcomes of PCI procedures in recent-STEMI cases with a totally occluded IRA and compared the findings with those in acute-STEMI cases.Among the 903 consecutive patients admitted with acute coronary syndrome, 250 were treated with PCI for type I STEMI with a totally occluded IRA. According to the time between symptom onset and diagnosis, patients were divided into the recent-STEMI (n = 32) and acute-STEMI (n = 218) groups. The background, procedure details, and short-term outcomes were analyzed. No significant differences between the groups were noted regarding patient demographics, acute myocardial infarction severity, or IRA distribution. Although the stent number and type were similar, significant differences were observed among PCI procedures, including the number of guidewires used, rate of microcatheter or double-lumen catheter use, and application rate of thrombus aspiration. The thrombolysis rate in the myocardial infarction flow 3-grade post-PCI did not differ significantly between the groups. Both groups had a low frequency of procedure-related complications. The in-hospital mortality rates were 0% and 4.6% in the recent-STEMI and acute-STEMI groups, respectively (P > 0.05).Although recent-STEMI cases required complicated PCI techniques, their safety, success rate, and in-hospital mortality were comparable to those of acute-STEMI cases.

BACKGROUND: Chronic total occlusion (CTO) is a high-risk factor for stent thrombosis, but little is known about the difference in neointimal healing between CTO and non-CTO lesions regarding implanted stents. We investigated factors affecting neointimal healing after stent implantation for CTO and non-CTO lesions using angioscopy. METHODS: We retrospectively evaluated 106 stents in 85 consecutive patients between March 2016 and July 2020. Their average age was 68 ± 11 years, and participants (73 male and 12 female) underwent follow-up angiography and angioscopy 1 year after percutaneous coronary intervention (PCI). The stents (n = 106) were divided into three groups according to the lesion status at the previous PCI: CTO (n = 17), acute coronary syndrome (ACS) (n = 35), and stable coronary artery disease without CTO or non-CTO (n = 54). RESULTS: The neointimal stent coverage grade was significantly lower in the CTO and ACS groups than in the non-CTO group (0.4 ± 0.5, 0.9 ± 0.8, and 1.4 ± 0.8, respectively, p < 0.001). Thrombi were significantly more frequent in CTO and ACS than in non-CTO (71 %, 51 %, and 15 %, respectively, p < 0.001). The yellow grade in CTO was comparable to that in ACS but significantly higher in CTO than in non-CTO (CTO vs. ACS vs. non-CTO 1.5 ± 0.7, 1.4 ± 0.6, and 0.9 ± 0.7, respectively, p = 0.007). CONCLUSIONS: Delayed healing occurs in stents implanted for CTO lesions. Longer dual-antithrombotic therapy may be beneficial.

Background:

Current practice in cardiogenic shock is guided by expert opinion in guidelines and scientific statements from professional societies with limited high quality randomized trial data to inform optimal patient management. An international panel conducted a modified Delphi process with the intent of identifying aspects of cardiogenic shock care where there was uncertainty regarding optimal patient management.

Methods:

An 18-person multidisciplinary panel comprising international experts was convened. A modified RAND/University of California Los Angeles appropriateness methodology was used. A survey comprising 70 statements was completed. Participants anonymously rated the appropriateness of each statement on a scale of 1 to 9: 1 to 3 inappropriate, 4 to 6 uncertain, and 7 to 9 appropriate. A summary of the results was discussed as a group, and the survey was iterated and completed again before final analysis.

Results:

There was broad alignment with current international guidelines and consensus statements. Overall, 44 statements were rated as appropriate, 19 as uncertain, and 7 as inappropriate. There was no disagreement with a disagreement index &lt;1 for all statements. Routine fluid administration was deemed to be inappropriate. Areas of uncertainty focused panel on pre-PCI interventions, the use of right heart catheterization to guide management, routine use of left ventricular unloading strategies, and markers of futility when considering escalation to mechanical circulatory support.

Conclusions:

While there was broad alignment with current guidance, an expert panel found several aspects of care where there was clinical equipoise, further highlighting the need for randomized controlled trials to better guide patient management and decision making in cardiogenic shock.

BACKGROUND: Because development of acute coronary syndrome (ACS) worsens the prognosis of patients with coronary artery disease, preventing recurrent ACS is crucial. However, the degree to which secondary prevention treatment goals are achieved in patients with recurrent ACS is unknown. METHODS: 214 consecutive ACS patients were classified as having First ACS (n=182) or Recurrent ACS (n=32), and the clinical characteristics of these groups were compared. Fifteen patients died or developed cardiovascular (CV) events during hospitalization, and the remaining 199 patients were followed from the date of hospital discharge to evaluate subsequent CV events. RESULTS: Patients in the Recurrent ACS group were older than those in the First ACS group (76.8±10.8 years vs 68.8±13.4 years, p=0.002) and had a higher rate of diabetes mellitus (DM) (65.6% vs 36.8%, p=0.003). The rate of achieving a low-density lipoprotein cholesterol (LDL-C) level of <70 mg/dL in the Recurrent ACS group was only 28.1%, even though 68.8% of these patients were taking statins. An HbA1c level of <7.0% was achieved in 66.7% of patients with recurrent ACS who had been diagnosed with DM. Overall, 12.5% of patients with recurrent ACS had received optimal treatment for secondary prevention. CV events after hospital discharge were noted in 37.9% of the Recurrent ACS group and 21.2% of the First ACS group (log-rank test: p=0.004). However, recurrent ACS was not an independent risk factor for CV events (adjusted hazard ratio: 2.09, 95% confidence interval: 0.95 to 4.63, p=0.068). CONCLUSION: Optimal treatment for secondary prevention was not achieved in some patients with recurrent ACS, and achievement of the guideline-recommended LDL-C goal for secondary prevention was especially low in this population.

BACKGROUND: Alcohol septal ablation (ASA) is a treatment option in patients with drug-refractory symptomatic hypertrophic obstructive cardiomyopathy (HOCM). In many patients, right bundle branch block (RBBB) develops during ASA because septal branches supply the right bundle branch. However, the clinical significance of procedural RBBB is uncertain.Methods and Results:We retrospectively reviewed 184 consecutive patients with HOCM who underwent ASA. We excluded 40 patients with pre-existing RBBB (n=10), prior pacemaker implantation (n=15), mid-ventricular obstruction type (n=10), and those lost to follow-up (n=5), leaving 144 patients for analysis. Patients were divided into 2 groups according to the development (n=95) or not (n=49) of procedural RBBB. ASA conferred significant decreases in the left ventricular pressure gradient (LVPG) in both the RBBB and no-RBBB group (from 74±48 to 27±27 mmHg [P<0.001] and from 75±45 to 31±33 mmHg [P<0.001], respectively). None of the RBBB patients developed further conduction system disturbances. The percentage reduction in LVPG at 1 year after the procedure was significantly greater in the RBBB than no-RBBB group (66±24% vs. 49±45%; P=0.035). Procedural RBBB was not associated with pacemaker implantation after ASA, but was associated with reduction in repeat ASA (odds ratio 0.34; 95% confidence interval 0.13-0.92; P=0.045). CONCLUSIONS: Although RBBB frequently occurs during the ASA procedure, it does not adversely affect clinical outcomes.

We herein report a case of mitochondrial disease with heart and intestinal tract involvement resulting in hemodynamic collapse. A 66-year-old woman was transferred to our hospital because of cardiogenic shock. Vasopressors were administered, and a circulatory support device was deployed. However, her hemodynamics did not improve sufficiently, and we detected abdominal compartment syndrome caused by the aggravation of chronic intestinal pseudo-obstruction as a complication. Insertion of a colorectal tube immediately decreased the intra-abdominal pressure, improving the hemodynamics. Finally, we diagnosed her with mitochondrial disease, concluding that the resulting combination of acute heart failure and abdominal compartment syndrome had aggravated the hemodynamics.

BACKGROUND: In the modern US cardiovascular intensive care unit (CICU), the incidence of non-cardiovascular disorders has increased and non-cardiovascular disorders are associated with an increase in morbidity and mortality. In Japan, however, data regarding the association between non-cardiovascular disorders and outcomes in the CICU are limited. METHODS: This study examined 490 consecutive admissions to a closed CICU at the Nippon Medical School Hospital from January to December 2017. Characteristics, diagnoses, treatments, and outcomes of admitted patients were identified. RESULTS: The most common primary diagnosis was acute coronary syndrome (50.4%), followed by acute heart failure (20.0%), arrhythmia (6.7%), and non-cardiovascular diseases (3.7%). The mortality rate and median length of stay (LOS) in the CICU were 4.7% and 4 (interquartile range, 2-8) days, respectively. Of all patients, 42.2% (n = 207) developed non-cardiovascular complications such as acute respiratory failure, acute kidney injury, or sepsis during CICU stay. Multivariate logistic regression analysis revealed that acute respiratory failure and sepsis were significantly associated with mortality in the CICU (odds ratio, 11.014 and 25.678, respectively; both p<0.05). The multiple linear regression analysis showed that acute kidney injury was significantly associated with LOS in the CICU (β=0.144, p = 0.002). CONCLUSIONS: Approximately half of patients admitted to the CICU had non-cardiovascular disorders including non-cardiovascular disease and non-cardiovascular complications, which were significantly associated with mortality and LOS in the CICU.

Gastrointestinal (GI) bleeding worsens the outcomes of critically ill patients in the intensive care unit (ICU). Owing to a lack of corresponding data, we aimed to investigate whether GI bleeding during cardiovascular-ICU (C-ICU) admission in acute cardiovascular (CV) disease patients is a risk factor for subsequent CV events. Totally, 492 consecutive C-ICU patients (40.9% acute coronary syndrome, 22.8% heart failure) were grouped into GI bleeding (n = 27; 12 upper GI and 15 lower GI) and non-GI bleeding (n = 465) groups. Thirty-nine patients died or developed CV events during hospitalization, and 453 were followed up from the date of C-ICU discharge to evaluate subsequent major adverse CV events. The GI bleeding group had a higher Acute Physiology and Chronic Health Evaluation II score (20.2 ± 8.2 vs. 15.1 ± 6.8, p < 0.001), higher frequency of mechanical ventilator use (29.6% vs. 13.1%, p = 0.039), and longer C-ICU admission duration (8 [5-16] days vs. 5 [3-8] days, p < 0.001) than the non-GI bleeding group. The in-hospital mortality rate did not differ between the groups. Of those who were followed-up, CV events after C-ICU discharge were identified in 34.6% and 14.3% of patients in the GI and non-GI bleeding groups, respectively, during a median follow-up period of 228 days (log rank, p < 0.001). GI bleeding was an independent risk factor for subsequent CV events (adjusted hazard ratio: 2.23, 95% confidence interval: 1.06-4.71; p = 0.035). GI bleeding during C-ICU admission was independently associated with subsequent CV events in such settings.

© 2020 The Author(s). Background: Protection from lethal ventricular arrhythmias leading to sudden cardiac death (SCD) is a crucial challenge after acute myocardial infarction (AMI). Cardiac sympathetic and parasympathetic activity can be noninvasively assessed using heart rate variability (HRV) and heart rate turbulence (HRT). The EMBODY trial was designed to determine whether the Sodium-glucose cotransporter 2 (SGLT2) inhibitor improves cardiac nerve activity. Methods: This prospective, multicenter, randomized, double-blind, placebo-controlled trial included patients with AMI and type 2 diabetes mellitus (T2DM) in Japan; 105 patients were randomized (1:1) to receive once-daily 10-mg empagliflozin or placebo. The primary endpoints were changes in HRV, e.g., the standard deviation of all 5-min mean normal RR intervals (SDANN) and the low-frequency-to-high-frequency (LF/HF) ratio from baseline to 24 weeks. Secondary endpoints were changes in other sudden cardiac death (SCD) surrogate markers such as HRT. Results: Overall, 96 patients were included (46, empagliflozin group; 50, placebo group). The changes in SDANN were + 11.6 and + 9.1 ms in the empagliflozin (P = 0.02) and placebo groups (P = 0.06), respectively. Change in LF/HF ratio was - 0.57 and - 0.17 in the empagliflozin (P = 0.01) and placebo groups (P = 0.43), respectively. Significant improvement was noted in HRT only in the empagliflozin group (P = 0.01). Whereas intergroup comparison on HRV and HRT showed no significant difference between the empagliflozin and placebo groups. Compared with the placebo group, the empagliflozin group showed significant decreases in body weight, systolic blood pressure, and uric acid. In the empagliflozin group, no adverse events were observed. Conclusions: This is the first randomized clinical data to evaluate the effect of empagliflozin on cardiac sympathetic and parasympathetic activity in patients with T2DM and AMI. Early SGLT2 inhibitor administration in AMI patients with T2DM might be effective in improving cardiac nerve activity without any adverse events. Trial Registration: The EMBODY trial was registered by the UMIN in November 2017 (ID: 000030158). UMIN000030158; https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000034442.

We report two cases of Impella-assisted coronary artery bypass grafting for acute myocardial infarction with cardiogenic shock. The first case involved coronary artery bypass grafting and mitral valve replacement, and the second involved off-pump coronary artery bypass grafting. Emergent Impella-assisted coronary artery bypass grafting was successfully performed in both cases. Our findings highlight the ability of Impella percutaneous left ventricular assist device to provide excellent hemodynamic support during the entire perioperative period.

Objective: To elucidate the current status of use of inferior vena cava filters (IVCFs) in cases of pulmonary embolism at institutions belonging to the Tokyo CCU Network.
Methods: We conducted a retrospective investigation of 832 consecutive cases of pulmonary embolism reported on survey forms to the Tokyo CCU Network between 2005 and 2010.
Results: Of 832 cases of pulmonary embolism, IVCFs were used in 338(40.6%) and not used in 415(49.9%). Their use was unclear in 79(9.5%) cases. The use rate gradually increased each year from 2005 until 2008 but decreased from 2009 onward. Moreover, 68.9% of the IVCFs used in cases were non-permanent types. In terms of pulmonary embolism severity, the rate of use was 37.2% in non-massive cases, 49.4% in sub-massive cases, 46.9% in massive cases, and 31.9% in collapse cases. Thirty-day mortality in cases of collapse in which IVCFs were not used was extremely high at 75.8%, suggesting that in many cases, rapid deterioration may occur with insufficient time for IVCF insertion. The differences in IVCF usage rate among institutions were large in the range of 12.5-90% from 2005 to 2008, which slightly declined to the range of 25.0-72.2% from 2009 to 2010.
Conclusions: We elucidated the current IVCF use status in cases of pulmonary embolism at institutions belonging to the Tokyo CCU Network. Since the status of use differed among institutions, future studies of effective methods of use are required. (c) 2013 Japanese College of Cardiology. Published by Elsevier Ltd. All rights reserved.

集中治療室における、過去5年間の急性心筋梗塞(AMI)患者663例に合併した発作性心房細動(PAF)の臨床背景とその治療選択および成績を後ろ向きに調査した。AMI後に発症したPAFに対するLandiololの使用経験もあわせて報告した。70歳以上が50%を占めており平均年齢は68.5±12.3歳であった。この症例の中で、CCU入院中にPAFは11.1%にあたる72例に認められた。PAF発症は、60・70歳代では10%に増加し、80歳以上では発症頻度が15%を超え、加齢に伴いPAF発症頻度は増加した。Landiolol投与により除細動前の心拍数は低下したが血行動態の悪化は認めなかった。

40歳代男。筋力トレーニング中に胸痛が出現し、嘔吐もきたした。心電図で、急性心筋梗塞と診断した。緊急冠動脈造影を行い、右冠動脈#3と左前下行枝#6において完全閉塞、右冠動脈#1〜#2では再疎通様のびまん性狭窄を認めた。今回の梗塞責任病変である前下行枝#6の完全閉塞に対し、血栓吸引術および冠動脈ステント留置を施行、#6の病変は0%に改善した。広範囲前壁梗塞で、循環補助として大動脈バルンパンピングを4日間、呼吸補助として非侵襲的陽圧換気を2日間行った。第9病日に立位負荷を行い、同日一般病棟へ転室した。なお、未分画ヘパリン持続静注による抗凝固療法は第5病日まで施行した。D-dimerの上昇を認め、第14病日に下肢静脈エコーを施行した。両側後脛骨静脈および左腓骨静脈に静脈血栓を認め、ワルファリンによる抗凝固療法を開始した。第57病日に軽快退院した。
