摘　　要：心力衰竭分为左室射血分数降低的收缩性心力衰竭和左室射血分数正常的心力衰竭(HF-NEF),后者又称收缩功能保留的心力衰竭(HF-PSF)。医学界对收缩性心力衰竭的研究远较HF-NEF的研究深入且透彻。然而,HF-NEF的发病率及病死率(尤其在老年人中)可能远远超过目前人们所认识的水平。因此,对HF-NEF的发病机制、诊断及预后判断成为医学界关注的热点,舒张功能不全病情发展标志的左房功能亦成为目前的主要研究方向。Heart failure has been divided into heart failure with reduced ejection fraction（systolic heart failure）and heart failure with normal ejection fraction（HF-NEF）or heart failure with preserved systolic function（HF-PSF）.Systolic heart failure has been more thoroughly studied than HF-NEF.However,the prevalence and mortality（especially in the elderly）of HF-NEF are much higher than expected.Therefore,the pathogenesis,diagnosis and prognosis of HF-NEF and the left atrial function in HF-NEF correlated with diastolic dysfunction have become the research focus.
