Heart Failure With Improved Ejection Fraction: Clinical Characteristics, Correlates of Recovery, and Survival
نویسندگان
چکیده
Current guidelines for the management of heart failure (HF) divide patients with HF into 2 categories: those with reduced ejection fraction (EF of ≤40%; HFrEF) and those with preserved ejection fraction (>40%; HFpEF). It has been recognized that a subset of patients with HFpEF previously had HFrEF. These patients with recovery or improvement in EF (HFiEF) may be clinically distinct from those with persistently preserved or reduced EF.

Effect of Exercise Training on Heart Rate Variability in Patients with Heart Failure After Percutaneous Coronary Intervention
Background: This study aims to evaluate the effect of exercise training on heart rate variability (HRV) and to determine the correlation between parameters of HRV and the ejection fraction in patients with heart failure after percutaneous coronary intervention.Material and Methods: Fifty patients with left ventricular ejection fraction ≤ 40% undergone percutaneous coronary intervention were r...

BACKGROUND Heart failure with recovered or improved ejection fraction (HFiEF) has been proposed as a new category of HF. Whether HFiEF is clinically distinct from HF with persistently reduced ejection fraction remains to be validated. METHODS AND RESULTS Of the 5010 subjects enrolled in the Valsartan Heart Failure Trial (Val-HeFT), 3519 had a baseline left ventricular EF of <35% and a follow-...

Background & Aim: Intra-aortic ballon pump(IABP) is a mechanical device that has become an accepted treatment modality for patients with severely compromised hemodynamics. The present retrospective study was undertaken to identify the major survival and nonsurvival determinants of patients who were in need of intra-aortic ballon pump support after cardiac surgery. Patients & Methods: Th...

Kawasaki disease is an acute inflammatory disorder of medium-sized arteries that predominantly affects cardiac coronary arteries and children under the age of 5 years. Cardiac involvement usually happens later than 10 days after the onset of illness. Most of cardiac complications are coronary artery abnormalities (ectasia or aneurysms) and subclinical myocarditis. Clinical myocarditis (symptoma...
