射血分数保留的心力衰竭是射血分数降低的心力衰竭的早期表现

摘要

＜正＞2016年欧洲心脏病学会（European Society of Cardiology,ESC）颁布的急性和慢性心力衰竭（心衰）诊治指南中提出了一个全新的概念,将左心室射血分数（left ventricular ejection fraction,LVEF）介于40%~49%的心衰患者定义为射血分数中等范围的心衰（heart failure with mid-range ejection fraction,HFmrEF）,从而填补了射血分数降低的心衰（heart failure with reduced ejection fraction,HFrEF）和射血分数保留的心衰（heart failure with preserved ejection fraction,HFpEF）之间的空白地带。也就是
