Background: There is a scarcity of reports on the clinical characteristics and management practice in contemporary all-comer patients with acute decompensated heart failure (ADHF). Methods and ...Results: The Kyoto Congestive Heart Failure (KCHF) registry is a prospective observational cohort study enrolling 4,056 consecutive patients who had hospital admission due to ADHF without any exclusion criteria between October 2014 and March 2016 in the 19 participating hospitals in Japan. Baseline characteristics, clinical presentations, management, and in-hospital outcomes were compared between heart failure (HF) with reduced left ventricular ejection fraction (LVEF; HFrEF, LVEF <40%), HF with mid-range LVEF (HFmrEF, LVEF 40–49%), and HF with preserved LVEF (HFpEF, LVEF ≥50%). Of the 4,041 patients with documented LVEF, 1,744 (43%) had HFpEF; 746 (19%), HFmrEF; and 1,551 (38%), HFrEF. The median age was 80 years (IQR, 72–86 years) in the entire population, and was higher with increasing LVEF (P<0.001). The in-hospital mortality rate was higher in the HFrEF than in the HFmrEF and HFpEF groups (9.2%, 4.8%, and 5.1%, respectively, P<0.001). Conclusions: This registry elucidated the clinical features and clinically relevant in-hospital outcomes in contemporary consecutive patients with ADHF in real-world clinical practice in Japan. When classified by LVEF, significant differences in characteristics and in-hospital outcomes existed between patients with HFrEF, HFmrEF, and HFpEF.
Background:The prevalence of and expected bleeding event rate in patients with the Japanese version of high bleeding risk (J-HBR) criteria are currently unknown in real-world percutaneous coronary ...intervention (PCI) practice.Methods and Results:We applied the J-HBR criteria in the multicenter CREDO-Kyoto registry cohort-3 that enrolled 13,258 consecutive patients who underwent first PCI. The J-HBR criteria included Japanese-specific major criteria such as heart failure, low body weight, peripheral artery disease and frailty in addition to the Academic Research Consortium (ARC)-HBR criteria. There were 8,496 patients with J-HBR, and 4,762 patients without J-HBR. The J-HBR criteria identified a greater proportion of patients with HBR than did ARC-HBR (64% and 48%, respectively). Cumulative incidence of the Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding was significantly higher in the J-HBR group than in the no-HBR group (14.0% vs. 4.1% at 1 year; 23.1% vs. 8.4% at 5 years, P<0.0001). Cumulative 5-year incidence of BARC 3/5 bleeding was 25.1% in patients with ARC-HBR, and 23.1% in patients with J-HBR. Cumulative incidence of myocardial infarction or ischemic stroke was also significantly higher in the J-HBR group than in the no-HBR group (6.9% vs. 3.6% at 1 year; 13.2% vs. 7.1% at 5 years, P<0.0001).Conclusions:The J-HBR criteria successfully identified those patients with very high bleeding risk after PCI, who represented 64% of patients in this all-comers registry.
The high controlling nutritional status (CONUT) score that represents poor nutritional status has been acknowledged to have prognostic implications in chronic heart failure. We aimed to investigate ...its role in acute decompensated heart failure (ADHF). Using the data from an multicenter registry that enrolled 4056 consecutive patients hospitalized for ADHF in Japan between 2014 and 2016, we analyzed 2466 patients in whom data on the components of the CONUT score at hospital presentation were available. The decrease of lymphocyte count and total cholesterol was assigned with 0, 1, 2, and 3 points and the decrease of albumin was assigned with 0, 2, 4, and 6 points according to the severity. We defined low CONUT score as 0-4 (N = 1568) and high CONUT score as 5-9 (N = 898). The patients in the high CONUT score group were older and more likely to have a smaller body mass index than those in the low CONUT score group. The high CONUT score group was associated with higher rate of death and infection during the index hospitalization compared to the low CONUT score group (9.0% versus 4.4%, and 21.9% versus 12.7%, respectively). After adjusting for confounders, the excess risk of high relative to low CONUT score for mortality and infection was significant (OR: 1.61, 95%CI: 1.05-2.44, and OR: 1.66, 95%CI: 1.30-2.12, respectively). The effect was incremental according to the score. High CONUT score was associated with higher risk for in-hospital mortality and infection in an incremental manner in patients hospitalized for ADHF.
Background:Patients with cancer-associated venous thromboembolism (VTE) are at high risk for recurrent VTE and are recommended to receive prolonged anticoagulation therapy if they are at a low risk ...for bleeding. However, there are no established risk factors for bleeding during anticoagulation therapy.Methods and Results:The COMMAND VTE Registry is a multicenter retrospective registry enrolling 3,027 consecutive patients with acute symptomatic VTE among 29 Japanese centers. The present study population consisted of 592 cancer-associated VTE patients with anticoagulation therapy. We constructed a multivariable Cox proportional hazard model to estimate the hazard ratio (HR) and 95% confidence interval (CI) of the potential risk factors for major bleeding. During a median follow-up period of 199 days, major bleeding occurred in 72 patients. The cumulative incidence of major bleeding was 5.8% at 3 months, 13.8% at 1 year, 17.5% at 2 years, and 28.1% at 5 years. The most frequent major bleeding site was gastrointestinal tract (47%). Terminal cancer (adjusted HR, 4.17; 95% CI, 2.22–7.85, P<0.001), chronic kidney disease (adjusted HR, 1.89; 95% CI 1.06–3.37, P=0.031), and gastrointestinal cancer (adjusted HR, 1.78; 95% CI, 1.04–3.04, P=0.037) were independently associated with an increased risk of major bleeding.Conclusions:Major bleeding events were common during anticoagulation therapy in real-world cancer-associated VTE patients. Terminal cancer, chronic kidney disease, and gastrointestinal cancer were the independent risk factors for major bleeding.
Background:The purpose of this study was to clarify the implementation rate of multidisciplinary heart failure (HF) care and cardiac rehabilitation (CR) in Japan, as well as the relationship between ...implementation rates and characteristics of the facility.Methods and Results:Survey participants were cardiologists who are members of the Japan Heart Failure Society and belonged to 1 of 845 medical institutions that are members of the Japan Heart Failure Society, as of April 2016. A total of 288 institutions (34.1%) returned the questionnaire. The percentages of hospitals implementing multidisciplinary HF care were 78.5% for inpatients and 32.6% for outpatients with HF. Inpatient and outpatient CR for HF had implementation rates of 80.4% and 56.5%, respectively. In addition, very few HF patients (7.3%, 3,741/51,323 patients) received outpatient CR. Both the presence of nurses certified in chronic HF care and registered CR instructors on staff were consistently associated with implementation of multidisciplinary HF care, and Japanese Circulation Society training hospitals, lower number of hospital beds, and presence of registered CR instructors on staff were consistently associated with implementation of CR.Conclusions:This first nationwide survey demonstrated that the implementation rates of multidisciplinary care and CR for HF, especially for outpatients, are low in Japan. Skilled healthcare professionals are expected to play important roles in the widespread implementation of this type of HF care in Japan.
Background: There is a scarcity of studies comparing the clinical outcomes after percutaneous coronary intervention (PCI) for women and men stratified by the presentation of acute coronary syndromes ...(ACS) or stable coronary artery disease (CAD).Methods and Results: The study population included 26,316 patients who underwent PCI (ACS: n=11,119, stable CAD: n=15,197) from the CREDO-Kyoto PCI/CABG registry Cohort-2 and Cohort-3. The primary outcome was all-cause death. Among patients with ACS, women as compared with men were much older. Among patients with stable CAD, women were also older than men, but with smaller difference. The cumulative 5-year incidence of all-cause death was significantly higher in women than in men in the ACS group (26.2% and 17.9%, log rank P<0.001). In contrast, it was significantly lower in women than in men in the stable CAD group (14.2% and 15.8%, log rank P=0.005). After adjusting confounders, women as compared with men were associated with significantly lower long-term mortality risk with stable CAD but not with ACS (hazard ratio HR: 0.75, 95% confidence interval CI: 0.69–0.82, P<0.001, and HR: 0.92, 95% CI: 0.84–1.01, P=0.07, respectively). There was a significant interaction between the clinical presentation and the mortality risk of women relative to men (interaction P=0.002).Conclusions: Compared with men, women had significantly lower adjusted mortality risk after PCI among patients with stable CAD, but not among those with ACS.
The Japanese population is rapidly aging because of its long life expectancy and low birth rate; additionally, the number of patients with heart failure (HF) is increasing to the extent that HF is ...now considered a pandemic. According to a recent HF registry study, Japanese patients with HF have both medical and care-related problems. Although hospitalization is used to provide medical services, and institutionalization is used to provide care for frail older adults, it can be difficult to distinguish between them. In this context, multidisciplinary management of HF has become increasingly important in preventing hospital readmissions and maintaining a patient’s quality of life. Academia has promoted an increase in the number of certified HF nurses and educators. Researchers have issued numerous guidelines or statements on topics such as cardiac rehabilitation, nutrition, and palliative care, in addition to the diagnosis and treatment of acute and chronic HF. Moreover, the Japanese government has created incentives through various medical and long-term care systems adjustments to increase collaboration between these two fields. This review summarizes current epidemiological registries that focus not only on medical but also care-related problems and the 10 years of multidisciplinary management experience in Japanese medical and long-term care systems.
Background:Data evaluating the effects of acute coronary syndrome (ACS) relative to stable coronary artery disease (CAD) on bleeding risk after percutaneous coronary intervention (PCI) are ...scarce.Methods and Results:From the CREDO-Kyoto Registry Cohort-3, 13,258 patients undergoing first PCI (5,521 ACS; 7,737 stable CAD) were identified. Patients were further stratified according to ACS presentation and Academic Research Consortium High Bleeding Risk (HBR): ACS/HBR: n=2,502; ACS/no-HBR: n=3,019; stable CAD/HBR: n=3,905; and stable CAD/no-HBR: n=3,832. The primary bleeding endpoint was Bleeding Academic Research Consortium 3/5 bleeding, whereas the primary ischemic endpoint was myocardial infarction (MI)/ischemic stroke. Compared with stable CAD, ACS was associated with a significantly higher adjusted risk for bleeding (hazard ratio HR 1.85; 95% confidence interval CI 1.68–2.03; P<0.0001), with a markedly higher risk within 30 days (HR 4.24; 95% CI 3.56–5.06; P<0.0001). Compared with the stable CAD/no-HBR group, the ACS/HBR, no-ACS/HBR, and ACS/no-HBR groups were associated with significantly higher adjusted risks for bleeding, with HRs of 3.05 (95% CI 2.64–3.54; P<0.0001), 1.89 (95% CI 1.66–2.15; P<0.0001), and 1.69 (95% CI 1.45–1.98; P<0.0001), respectively. There was no excess adjusted risk of the ACS relative to stable CAD group for MI/ischemic stroke (HR 1.07; 95% CI 0.94–1.22; P=0.33).Conclusions:Bleeding risk after PCI depended on both ACS presentation and HBR, with a significant effect of ACS within 30 days.
Background:The Hyogo Prefectural Government has been enforcing a smoking ban ordinance since April 2013. The present survey was conducted to determine the extent to which the smoking ban has been ...successfully implemented in eating establishments in Kobe City and Amagasaki City.Methods and Results:The Health and Welfare Department of the Hyogo Prefectural Government provided a list of eating establishments in Kobe and Amagasaki City. From these, we chose 1,300 from each city using random number generation. Responses were obtained from 310 establishments in Kobe City (response rate: 23.8%) and 297 in Amagasaki City (22.8%). Overall, 58.1% of the establishments surveyed in Kobe City were aware of the ordinance, a recognition rate significantly higher than that of Amagasaki City, where only 45.5% of eateries were aware of the ordinance (P=0.003). Of the Kobe City eateries, 31.7% had succeeded in implementing a complete ban on smoking. In Amagasaki City, the rate was significantly lower, at just 13.4% (P<0.001). A logistic regression analysis showed that coffee shops, Japanese-style taverns, bars, and eating establishments that served alcohol were the independent significant predictors of low compliance. Kobe City restaurants, women, and families were the independent significant predictors of high compliance with the complete smoking ban.Conclusions:The rates of recognition and implementation of the complete smoking ban were significantly lower in Amagasaki City than in Kobe City. There needs to be a strong and continuous socialization campaign to promote the ordinance.
