AIMS Heart failure patients with reduced and preserved left ventricular (LV) ejection fraction (EF) show reduced exercise capacity. We explored the relationship between exercise capacity and systolic and diastolic myocardial function in heart failure patients. METHODS AND RESULTS Exercise capacity, by peak oxygen uptake (VO2), was assessed in 100 patients (56 ± 12 years, NYHA functional class...
BACKGROUND AND OBJECTIVES The burden of heart failure has increased in Korea. This registry aims to evaluate demographics, clinical characteristics, management, and long-term outcomes in patients hospitalized for acute heart failure (AHF). SUBJECTS AND METHODS We prospectively enrolled a total of 5625 consecutive subjects hospitalized for AHF in one of 10 tertiary university hospitals from Ma...
Abstract Background Acute heart failure (AHF) with left ventricle (LV) dysfunction is characterized by a condition of afterload mismatch without preload reserve. LV ejection fraction (LVEF) and stroke volume (SV) become thus dependent on the afterload. Owing to its arteriolar vasodilator properties, sodium nitroprusside (SNP) may reduce result particularly beneficial in this setting, improving ...
Background—Heart failure with preserved ejection fraction (EF) is a common syndrome, but trends in treatments and outcomes are lacking. the proportion of hospitalizations for HF–preserved EF increased from 33% to 39% (PϽ0.0001). In multivariable analyses, use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers at discharge decreased in all EF groups, and -blocker use incr...
INTRODUCTION AND OBJECTIVES Little is known about how prognosis is influenced by readmission for acute heart failure (AHF) following non-ST-segment elevation acute coronary syndrome (NSTEACS). The aim of this study was to determine the prognostic effect of a first admission for AHF on the risk of acute myocardial infarction (AMI) or death in patients who survived an episode of high-risk NSTEACS...
In patients with acute decompensated heart failure (ADHF), sex differences considering clinical and pathophysiologic features are not fully understood. We investigated sex differences in left ventricular (LV) ejection fraction (LVEF), plasma B-type natriuretic peptide (BNP) levels, and prognostic factors in patients with ADHF in Japan. We studied 748 consecutive ADHF patients of 821 patients re...
PURPOSE OF REVIEW The purpose of this review is to describe the extent and scope of acute heart failure (AHF), place it within its clinical context and highlight some of the difficulties in defining it as a pathophysiological entity. RECENT FINDINGS A diagnosis of AHF is made when patients present acutely with signs and symptoms of heart failure, often with decompensation of pre-existing card...
AIMS Data on the prognostic role of left and right bundle branch blocks (LBBB and RBBB), and nonspecific intraventricular conduction delay (IVCD; QRS ≥ 110 ms, no BBB) in acute heart failure (AHF) are controversial. Our aim was to investigate electrocardiographic predictors of long-term survival in patients with de novo AHF and acutely decompensated chronic heart failure (ADCHF). METHODS AND ...
Heart failure and preserved ejection fraction (HFpEF) is defined as heart failure symptoms and signs with a normal or near-normal ejection fraction (EF) with evidence of diastolic dysfunction. The few Middle Eastern studies that have been conducted were designed to compare patients with heart failure reduced ejection fraction (HFrEF) and HFpEF.The aim of this study was to study Saudi patients w...
Over the past few decades, research on the peptide hormone, relaxin, has significantly improved our understanding of its biological actions under physiological and diseased conditions. This has facilitated the conducting of clinical trials to explore the use of serelaxin (human recombinant relaxin). Acute heart failure (AHF) is a very difficult to treat clinical entity, with limited success so ...
