【摘要】 射血分数保留型心力衰竭(HFpEF)被定义为左心室射血分数(LVEF)≥50%,同时伴有钠尿肽(BNP)水平升高或其他充血证据。HFpEF有高发病率及高致死率的特点，现已超过射血分数减少型心力衰竭(HFrEF),成为心力衰竭的主流。本文对HFpEF的定义、流行病学、分类、诊断、病理、合并症及其治疗予以综述，旨在为临床研究提供证据。更多还原

【Abstract】 Heart failure with preserved ejection fraction(HFpEF) is defined as having a left ventricular ejection fraction(LVEF) of ≥50% accompanied by elevated natriuretic peptide(BNP) levels or other evidence of congestion. HFpEF is characterized by high morbidity and mortality rates and has surpassed heart failure with reduced ejection fraction(HFrEF) to become the predominant form of heart failure. This article reviewed the definition, epidemiology, classification, diagnosis, pathology, comorbidities, and treatment of HFpEF, providing evidence for clinical research.更多还原
