We aimed to compare the usefulness of plasma levels of B-type natriuretic peptide (BNP) for long-term risk stratification among patients with heart failure (HF) with preserved left ventricular ejection fraction (LVEF) (HFpEF), borderline HFpEF, and HF with reduced LVEF (HFrEF) in the same HF cohort. In the CHART-2 Study (N = 10,219), we categorized 4301 consecutive Stage C/D HF patients (mean age 68.7 years, female 32.

In addition, it is still unclear whether patients benefit from statins regardless of low-density lipoprotein cholesterol levels.
Methods And Results: We examined 2444 consecutive stage C or D HF patients with ischemic heart disease registered in CHART-2 (Chronic Heart Failure Registry and Analysis in the Tohoku District 2), a multicenter, prospective, observational cohort study in Japan.
Aims: The temporal changes and sex differences in post-traumatic stress disorder (PTSD) after natural disasters remain unclear. Therefore, we examined the prevalence, prognostic impacts, and determinant factors of PTSD after the Great East Japan Earthquake (GEJE) of 11 March 2011 in cardiovascular (CV) patients registered in the Chronic Heart Failure Analysis and Registry in the Tohoku District (CHART)-2 Study (n = 10 219), with a special reference to sex.
Methods And Results: By self-completion questionnaires of the Japanese-language version of the Impact of Event Scale-Revised (IES-R-J), the prevalence of PTSD, defined as IES-R-J score ≥25, was 14.
Background: The new category of heart failure (HF), HF with mid-range left ventricular ejection fraction (LVEF) (HFmrEF), has recently been proposed. However, the clinical features of HFmrEF, with reference to HF with preserved LVEF (HFpEF) and HF with reduced LVEF (HFrEF) in the same HF cohort, remain to be fully examined.
Methods And Results: In the Chronic Heart Failure Analysis and Registry in the Tohoku District-2 Study, we examined 3480 consecutive HF patients with echocardiography data consisting of 2154 HFpEF (LVEF ≥50%), 596 HFmrEF (LVEF 40-49%) and 730 HFrEF (LVEF <40%).
Background: We and others have previously reported that the Great East Japan Earthquake (GEJE) caused a significant but transient increase in cardiovascular diseases and deaths in the disaster area. However, it remains to be examined whether the GEJE had a long-term prognostic influence in large-scale cohort studies. This point is important when analyzing the data before and after the GEJE in the cohort studies in the disaster area.

Methods and results: The present study included 5,382 consecutive patients at high risk of HF enrolled in the CHART-2 Study (n=10,219).
Background: It remains to be elucidated whether addition of renin-angiotensin-aldosterone system (RAAS) inhibitors and/or β-blockers to loop diuretics has a beneficial prognostic impact on chronic heart failure (CHF) patients.
Methods and results: From the Chronic Heart failure Analysis and Registry in the Tohoku district 2 (CHART-2) Study (n=10,219), we enrolled 4,134 consecutive patients with symptomatic stage C/D CHF (mean age, 69.3 years, 67.
Background: The prognostic impact of new-onset atrial fibrillation (AF) is not fully elucidated.
Methods And Results: We examined 4,818 consecutive stage C/D chronic heart failure (CHF) patients in the Chronic Heart Failure Analysis and Registry in the Tohoku District-2 (CHART-2) Study (n=10,219). At enrollment, 1,859 (38.
Background: Temporal trends in clinical characteristics, management and prognosis of patients with symptomatic heart failure (HF) remain to be elucidated in Japan.
Methods and results: From the Chronic Heart Failure Analysis and Registry in the Tohoku District-1 (CHART-1; 2000-2005, n=1,278) and CHART-2 (2006-present, n=10,219) Studies, we enrolled 1,006 and 3,676 consecutive symptomatic stage C/D HF patients, respectively. As compared with the patients in the CHART-1 Study, those in the CHART-2 Study had similar age and sex prevalence, and were characterized by lower brain natriuretic peptide, higher prevalence of preserved left ventricular ejection fraction (LVEF) and higher prevalence of hypertension, diabetes mellitus and ischemic heart disease (IHD), particularly IHD with LVEF ≥50%.
Background: We aimed to elucidate the prognostic impact of anemia with special reference to the clinical background of patients with chronic heart failure (CHF).
Methods and results: We examined 4,646 consecutive patients with Stage C/D CHF registered in the Chronic Heart Failure Analysis and Registry in the Tohoku District-2 (CHART-2) Study (n=10,219). Among them, 1,627 (35%) had anemia and were characterized by higher age (74 vs.
Background: It is unclear whether the prognostic impact of diabetes mellitus (DM) in chronic heart failure (CHF) is influenced by ischemic heart disease (IHD) and/or nephropathy.
Methods And Results: We enrolled 4,065 consecutive patients with stage C/D CHF (mean age, 69.0 years; 68.
Background: The risk of patients with aortic stenosis (AS) should be stratified not only by AS severity but also by comorbidities.
Methods And Results: We aimed to develop a risk score for mortality in 412 patients with AS (pressure gradient ≥30 mmHg, mean age 74.9 years, male 52.
Background: Recent trends in the clinical characteristics, management and prognosis of dilated cardiomyopathy (DCM) remain to be examined in Japan.
Methods And Results: We compared 306 and 710 DCM patients in the Chronic Heart Failure Analysis and Registry in the Tohoku District (CHART)-1 (2000-2005, n=1,278) and the CHART-2 (2006-present, n=10,219) Studies, respectively. Between the 2 groups of DCM patients, there were no significant differences in baseline characteristics.
Background: We examined the prevalence, predictors and prognostic impact of post-traumatic stress disorder (PTSD) after the Great East Japan Earthquake in patients with cardiovascular disease (CVD) in the CHART-2 study. METHODS AND RESULTS: The prevalence of PTSD was 14.7% at 6 months after the Earthquake.
