射血分数保留的心力衰竭运动康复研究进展

2022年美国心脏协会(American Heart Association,AHA)/美国心脏病学会(American College of Cardiology,ACC)/美国心力衰竭学会(Heart Failure Society of America,HFSA)心力衰竭指南中,根据左室射血分数和病史,将心力衰竭分为射血分数降低的心力衰竭(heart failure with reduced ejection fraction,HFr EF)、射血分数轻度降低的心力衰竭(heart failure with mildly reduced ejection fraction,HFmr EF)、射血分数改善的心力衰竭(heart failure with improved ejection fraction,HFimp EF)和射血分数保留的心力衰竭(heart failure with preserved ejection fraction,HFp EF),其中,HFp EF定义为左室射血分数≥50%的心力衰竭^([1])。
