Background With aging population, the prevalence and incidence of heart failure (HF) have been increasing worldwide. However, the characteristics and outcomes of patients with HF in an era of aging are not well established in Japan.Methods and Results:The Japanese Registry Of Acute Decompensated Heart Failure (JROADHF), a retrospective, multicenter, nationwide registry, was designed to study the clinical characteristics and outcomes of patients hospitalized with HF throughout Japan in 2013. One hundred and twenty-eight hospitals were selected by cluster random sampling and 13,238 hospitalized patients with HF were identified by medical record review. Demographics, medical history, severity, treatment, and in-hospital and long-term outcome data were collected from the Diagnostic Procedure Combination and medical charts. Data were analyzed using univariate and multivariate logistic regression or Cox regression analysis. The mean age of registered patients was 78.0±12.5 years and 52.8% were male. Elderly patients (age >75 years) accounted for 68.9%, and HF with preserved ejection fraction (HFpEF) accounted for 45.1%. Median length of hospital stay was 18 days and in-hospital mortality was 7.7%. The median follow-up period was 4.3 years, and the incidence rates for cardiovascular death and rehospitalization for HF were 7.1 and 21.1 per 100 person-years, respectively. Conclusions A contemporary nationwide registry demonstrated that hospitalized HF patients were very elderly, HFpEF was common, and their prognosis was still poor in Japan.

BACKGROUND Prognosis after acute decompensated heart failure (ADHF) is poor. An appropriate risk score that would allow for improved care and treatment of ADHF patients after discharge, however, is lacking. Methods and Results: We used 2 HF cohorts, the NARA-HF study and JCARE-CARD, as derivation and validation cohorts, respectively. The primary endpoint was all-cause death during the 2-year follow-up, excluding in-hospital death. Age, hemoglobin (Hb), and brain natriuretic peptide (BNP) at discharge were identified as independent risk factors. We determined 3 categorizations on the basis of these parameters, termed A2B score: age (

Background: Implantable cardioverter-defibrillator (ICD) has improved prognosis in fatal arrhythmia and the number of ICD implantations has increased. ICD-related psychological problems and impaired quality of life (QOL), however, have been observed. This study examined whether gender differences exist in QOL and psychological disturbances in ICD patients. Methods and Results: Consecutive outpatients (n=179; mean age, 60.5±15.9 years; 81% male) with ICD implantations completed questionnaires consisting of the Short Form-8 (SF-8), Beck Depression Inventory, Impact of Event Scale-Revised (IES-R), State-Trait Anxiety Inventory, and Worries about ICD. One-way multivariate analysis of variance (MANOVA) showed women to have impaired QOL on the role physical functioning (F15,157=4.57, P

Background: A disease management program can reduce mortality and rehospitalization of patients with heart failure (HF), but little is known about whether it can improve psychological status. The purpose of this study was to determine the effects of home-based disease management on the psychological status of patients with HF. Methods and Results: We randomly assigned patients hospitalized for HF to undergo either home-based disease management (n=79) or usual care (n=82). The mean age of the study patients was 76 years, 30% were female, and 93% were in NYHA class I or II. Home-based disease management was delivered by nurses via home visit and telephone follow-up to monitor symptoms and body weight and to educate patients. The primary endpoint was psychological status, including depression and anxiety assessed by the Hospital Anxiety and Depression Scale during follow-up of 1 year. Secondary endpoints included quality of life, all-cause death and hospitalization for HF. The intervention group had significantly lower depression (P=0.043) and anxiety (P=0.029) scores than the usual-care group. There were no significant differences in all-cause death [hazard ratio (HR) 1.02, 95% confidence interval (CI) 0.37–2.61, P=0.967]. However, hospitalization for HF was significantly lower in the intervention group than in the usual-care group (HR 0.52, 95% CI 0.27–0.96, P=0.037). Conclusions: Home-based disease management improved psychological status and also reduced rehospitalization for HF in patients with HF. (Circ J 2013; 77: 926–933)

Background: The mode of death has not been investigated in the registry data of patients with heart failure and reduced ejection fraction (HFREF) vs. preserved ejection fraction (HFPEF). The aim of the present study was therefore to carry out this comparison. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) prospectively studied the characteristics and treatments in a broad sample of 2,675 patients hospitalized with worsening HF, and followed them for an average of 2.1 years. This study included 323 patients in whom information on both the mode of death and left ventricular EF on echocardiography could be obtained. The mode of death was cardiovascular (CV) in 63% (including 17% sudden, 36% HF, 3% myocardial infarction, and 3% stroke), non-CV in 23%, and unknown in 14%. The prevalence of CV death including sudden death was high in patients with HFREF compared to HFPEF (68% vs. 58%, P=0.020). HF death, the most common mode of death, was similar between groups (37% vs. 35%, P=0.694). In contrast, non-CV mortality was significantly higher in HFPEF than those with HFREF (28% vs. 18%, P=0.021). Conclusions: In 60-70% of deaths the mode was CV, and HF death was the most common mode of death in either HFREF or HFPEF. The prevalence of sudden death was lower, and that of non-CV death higher, in HFPEF compared with HFREF. (Circ J 2012; 76: 1662–1669)

Background: Loop diuretics are commonly used in patients with heart failure (HF) to remove retained fluid and improve symptoms. However, they may potentially worsen outcomes in HF. It remains unknown whether the use of loop diuretics is associated with adverse HF outcomes in routine clinical practice. We thus determined the effects of loop diuretic use at discharge on long-term mortality and rehospitalization among patients hospitalized with HF. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) prospectively studied the characteristics and treatments of a broad sample of patients hospitalized with worsening HF and followed for 2.1 years. Among a total of 2,549 HF patients, loop diuretics were used by 2,015 patients (79%), but not 534 patients (21%). The mean age was 70.7 years and 60% were male. Etiology was ischemic in 32% and mean left ventricular ejection fraction was 42%. After adjustment for covariates, discharge use of loop diuretics was associated with significant adverse risks of cardiac death (adjusted hazard ratio [HR] 2.348, 95% confidence interval [CI] 1.246-4.423, P=0.008) and rehospitalization (adjusted HR 1.427, 95% CI 1.040-1.959, P=0.027). Conclusions: Among patients hospitalized with worsening HF, loop diuretic use at discharge was associated with long-term adverse outcomes, which suggests that routine chronic use of loop diuretics may be harmful for patients with HF.

Background: Aging is associated with adverse outcomes in patients with cardiac diseases. Whether elderly patients hospitalized with heart failure (HF) had increased risks for mortality and rehospitalization compared with younger patients during the long-term follow-up was examined. The predictors of these adverse outcomes were also identified. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) studied prospectively the characteristics and treatments in a broad sample of 2,675 patients hospitalized with worsening HF and the outcomes were followed up. The majority of elderly patients were female, had lower body mass index (BMI), a higher rate of ischemic, valvular, and hypertensive heart disease as etiologies of HF, a lower estimated glomerular filtration rate (eGFR), lower hemoglobin, and higher left ventricular ejection fraction values. Even after adjustment for covariates, the elderly patients were associated with higher risks of adverse outcomes. The predictors for all-cause death were: lower eGFR, lower BMI, male sex, sustained ventricular tachycardia or fibrillation (VT/VF), and the use of diuretics at discharge. Conclusions: Among patients hospitalized with HF, elderly patients had a worse prognosis than younger patients. Lower eGFR, lower BMI, male sex, sustained VT/VF, and diuretic use were independent predictors for all-cause death in these patients with higher risk. (Circ J 2011; 75: 2403-2410)

Background: Obesity is a risk factor for cardiovascular disease (CVD) and is also associated with an increased risk of death in subjects without CVD. However, in heart failure (HF), elevated body mass index (BMI) has been shown to be associated with better prognosis, but it is unknown whether this is the case in unselected HF patients encountered in routine clinical practice in Japan. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) studied prospectively the characteristics and treatments in a broad sample of patients hospitalized with worsening HF and the outcomes were followed for 2.1 years. Study cohort (n=2,488) was classified into 3 groups according to baseline BMI

Background: Previous studies demonstrated that β-blocker use at the time of hospital discharge significantly increased postdischarge treatment rates, associated with an early (60- to 90-day) survival benefit in patients with heart failure (HF). However, it is unknown whether this therapeutic approach can also improve the long-term survival. We thus examined the long-term effects of β-blocker use at discharge on outcomes in patients hospitalized for HF and left ventricular systolic dysfunction (LVSD) (ejection fraction

Background The impact of psychosocial states, such as depression or anxiety, and social support on the outcomes of stable outpatients with mild heart failure (HF) has not been evaluated in the "real world" clinical practice. Methods and Results In the present study, 139 patients with a prior history of admission for HF provided the baseline demographic, clinical, socio-environmental, and psychosocial information. Cardiac death or re-admission because of worsening of HF was monitored during the follow-up period of 1 year. The prevalence of depression and anxiety were 37% and 37%, respectively, in HF patients. Depression was independently associated with male (sβ=-0.36, P=0.01), social ties (sβ=0.22, P=0.04) and low social support (sβ=-0.39, P

Background: Anemia is common in patients with heart failure (HF) and is associated with worse outcomes. However, the effects of anemia are unknown in an unselected group of HF patients encountered in routine clinical practice in Japan. The impact of anemia on long-term outcomes including mortality and rehospitalization among patients hospitalized with HF was thus assessed. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) prospectively studied the characteristics and treatments in a broad sample of patients hospitalized with worsening HF and the outcomes were followed. Study cohorts (n=1,960) were classified into 4 groups by discharge hemoglobin quartiles

Background: Previous studies have demonstrated that renal dysfunction is common in patients with heart failure (HF), but it is not known whether chronic kidney disease (CKD) is associated with increased risks of long-term adverse outcomes in unselected HF patients encountered in current routine clinical practice in Japan. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) prospectively studied a broad sample of patients hospitalized with worsening HF and their outcomes with an average of 2.4 years of follow-up. The study cohort (n=2,013) were classified into 3 groups by estimated glomerular filtration rate (eGFR): ≥60 (n=579), 30-59 (n=1,025), and

Background: Atrial fibrillation (AF) is a common arrhythmia in patients with heart failure (HF), but its prognostic importance is controversial. The effect of AF on long-term outcomes, including mortality and rehospitalization, among unselected HF patients hospitalized with HF in routine clinical practice in Japan was assessed in the present study. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) prospectively studied the characteristics and treatment strategies of a broad sample of patients hospitalized with worsening HF and the outcomes were followed with an average of 2.4 years of follow-up. The study cohort (n=2,659) was grouped according to the presence (n=937; 35.2%) or absence (n=1,722; 64.8%) of AF at baseline. After multivariable adjustment, patients with and without AF had a comparable risk for all-cause death (adjusted hazard ratio (HR) 0.931, 95% confidence interval (CI) 0.690-1.258, P=0.643), cardiac death (adjusted HR 0.949, 95%CI 0.655-1.377, P=0.784), rehospitalization because of the worsening HF (adjusted HR 1.028, 95%CI 0.816-1.295, P=0.816), and all-cause death or rehospitalization (adjusted HR 1.039, 95%CI 0.842-1.281, P=0.722). Conclusions: Among patients hospitalized for HF in Japan, AF was common, but was not an independent risk for long-term adverse outcomes, including death or rehospitalization, in routine clinical practice.

Background: Heart failure (HF) with preserved ejection fraction (EF) is common. We compared the characteristics, treatments, and outcomes in HF patients with reduced vs preserved EF by using the national registry database in Japan. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) is a prospective observational study in a broad sample of patients hospitalized with worsening HF. The study enrolled 2,675 patients from 164 hospitals with an average of 2.4 years of follow-up. Patients with preserved EF (EF ≥50% by echocardiography; n=429) were more likely to be older, female, have hypertension and atrial fibrillation, and less likely to have ischemic etiology compared with those with reduced EF (EF

Background The characteristics and outcomes of patients discharged from hospitals with a diagnosis of heart failure (HF) have been described by a number of previous epidemiological studies. However, very little information is available on this issue in general practice in Japan. Methods and Results The Japanese Cardiac Registry of Heart Failure in General Practice (JCARE-GENERAL) is designed to study the characteristics, treatment and outcomes prospectively in a broad sample of outpatients with HF who were managed by cardiologists in hospital (Hospital-HF) and primary care physicians in general practice (GP-HF). Out of 2,685 patients with HF, 1,280 patients were Hospital-HF and 1,405 GP-HF. Compared to the Hospital-HF patients, GP-HF patients were more likely to be elderly and female, and they had a higher prevalence of hypertensive heart disease as a cause of HF. Angiotensin-converting enzyme inhibitors, angiotensin receptor blockers and β-blockers were more prescribed to Hospital-HF than GP-HF patients. At the follow-up of 1.2 year, after adjustment, the mortality was comparable between the Hospital-HF and GP-HF groups, whereas HF-related admission was higher in the Hospital-HF group than in in the GP-HF group. Conclusions Based on the JCARE-GENERAL, the characteristics, treatment and outcomes of GP-HF patients differed from those of Hospital-HFpatients in Japan. (Circ J 2007; 71: 449 - 454)

Background Heart failure (HF), defined as a complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood, is a leading cause of mortality and hospitalization for adults older than 65 years in the industrialized countries. The characteristics and outcome of patients with HF have been described by several epidemiological studies and large scale clinical trials, performed mainly in the United States and Europe. Very little information is available on this issue in Japan. Methods and Results The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) is designed to prospectively study the characteristics, treatment, and outcomes of a broad sample of patients hospitalized with HF at teaching hospitals throughout Japan between January 2004 to June 2005 and the outcomes, including death and hospital readmission, will be followed through 2006 (mean follow-up at least 1 year). Participating cardiologists identify patients admitted for worsening of HF symptoms. Demographics, medical history, severity, treatment, and outcome data are collected and entered into a database via secure web browser technology. As of June 2005, baseline data for 2,676 patients with HF have been registered from 164 participating hospitals. Conclusions The JCARE-CARD will provide important insights into the management of patients with HF in routine clinical practice in Japan, thus providing the framework for improved management strategies for these patients.
