老年人舒张性心力衰竭

随着人口老龄化的增加，舒张性心力衰竭（DHF）的患病率逐步上升，严重威胁老年人的生命，现有的诊断方法对DHF的诊断有一定局限性，不同国家的心衰指南对于DHF的诊断标准也不完全相同，现有的治疗方案对DHF患者的自然病程和预后改善欠佳，因此成为目前的研究热点。现对老年性DHF最新的发病机制及诊断治疗进展进行阐述。

Diastolic heart failure in the elderly

With the increase in aging population, the prevalence of diastolic heart failure （DHF） is gradually increased, and is a serious threat to the life of the elderly. The current diagnostic methods have certain limitations to the diagnosis of DHF, and its diagnostic criteria are not identical in the heart failure guidelines from different countries. What＇s more, the existing therapeutic regime can not alter the natural course of DHF and improve its prognosis. Therefore, DHF becomes a research focus. This article aimed to introduce the new progress in the pathogenesis, diagnosis and treatment of DHF.
