左心室射血分数(left ventricular ejection fraction,LVEF)保存的心力衰竭(心衰)(heart failure with preserved ejection fraction,HFpEF)是一近年来逐渐受到重视的心衰类型,发病率逐年升高,致死率和致残率居高不下,目前在发病机制、诊断、治疗方面仍然存在很多不确定之处,为当下心衰领域的研究热点。概念20世纪70年代末期开始有报道在肥厚型心肌病、主动脉狭窄、高血压性心脏病导致的心衰中
Heart failure with preserved ejection fraction (LVEF) preserved by left ventricular ejection fraction (LVEF) is a type of heart failure that has been receiving more and more attention in recent years. The incidence of HFPEF is increasing year by year. The rate and the morbidity rate remains high, there are still many uncertainties in the pathogenesis, diagnosis and treatment, which is the hot spot in the field of heart failure at present. The concept of the late 1970s has been reported in hypertrophic cardiomyopathy, aortic stenosis, heart failure caused by hypertensive heart disease
