    心力衰竭是老年人常见疾病，是多种心血管疾病的最终转归。按照左心室射血分数(left ventricular ejection fraction，LVEF)水平可分为射血分数降低心力衰竭(heart failure with reduced left ventricular ejection fraction，HFrEF)、射血分数保留心力衰竭(heart failure and preserved ejection fraction，HFpEF)以及射血分数中间值的心力衰竭(heart failure with mid-range ejection fraction，HFmrEF)。其中，HFpEF在老年人中最为常见 ......
