血压与慢性心力衰竭预后及管理的研究进展

摘要

慢性心力衰竭(chronic heart failure,CHF)影响全球约2%的成年人口,心力衰竭的患病率与年龄相关,60岁以下人群患病率 10%^([1])。目前依据LVEF,将心力衰竭分为射血分数降低的心力衰竭(heart failure with reduced ejection fraction, HFrEF,LVEF<40%)、射血分数保留的心力衰竭(heart failure with preserved ejection fraction,HFpEF,LVEF≥50%)和射血分数中间值的心力衰竭(heart failure with mid-range ejection fraction, HFmrEF,40%≤LVEF<50%)。
