21、部分，代表了一家中心的心脏医疗水平，救治水平和管理水平，更与医疗单位或中心的现代化水平挂钩定义 心力衰竭是由于任何心脏结构或功能异常导致心室充盈或射血功能受损的一组临床综合征，其主要临床表现为呼吸困难和乏力（活动耐量受限），以及液体潴留（肺淤血和外周水肿）。心衰为各种心脏疾病的眼中和终末阶段，发病率高，是当今最重要的心血管病之一。心衰发展分为4个阶段根据心衰发生发展的过程，从心衰的危险因素进展成结构性心脏病，出现心衰症状，直至难治性终末期心衰,可分成4个阶段。前心衰(A)前临床心衰(B)临床心衰(C)难治性终末期心衰(D)这4个阶段不同于纽约心脏协会(NYHA)的心功能分级。心衰阶段的划分正是

22、体现了重在预防的概念，其中预防患者从阶段A进展至阶段B，即防止发生结构性心脏病，以及预防从阶段B进展至阶段C,以至于进展到D阶段。依据左室射血分数(LVEF),心衰可分为 LVEF降低的心衰(heart failure reduced left ventricular ejection fraction,HF-REF)LVEF保留的心衰(heart failure with preserved left ventricular ejection fraction,HF-PEF).LVEF是心衰患者分类的重要指标，也与预后及治疗反应相关。LVEF保留或正常的情况下收缩功能仍可能是异常的。CASE

30、示EF从18%增加到30%左心室血栓消失。下肢水肿消失。心电图仍然房扑。病人出院，门诊随访。静息心肌灌注显像：左室心腔明显扩大，后壁心肌血流灌注轻度减低。随访6个月后病人一般情况稳定，无心悸胸闷，气喘等症状，已经开始正常工作。思考病人的主要病因是肥胖，因此控制体重是主要的，开始阶段对体重控制没有重视，病人症状控制不好，症状反复，从控制体重开始，病情逐步好转并趋于稳定。在之后的随访过程中，继续控制体重，心脏结构与功能明显好转。房扑转为窦律。说明，对于肥胖型心肌病的治疗，预后要比原发性扩张型心肌病要好。Should We Target Obesity in Advanced Heart Failu
