心力衰竭是具有多样表现的综合征,可以通过射血分数和心室收缩功能确诊,关于射血分数减少的心力衰竭患者的病理生理及治疗途径已经进行了大量研究,然而心力衰竭及射血分数正常或减少患者心室收缩功能不全的流行及分布未见有系统报道。本研究对社区居民心力衰竭患者的射血分数、 Heart failure is a syndrome with diverse manifestations that can be diagnosed by ejection fraction and ventricular systolic function. Much research has been carried out on the pathophysiology and treatment of heart failure patients with reduced ejection fraction, however, heart failure and ejection fraction are normal Or reduce the prevalence and distribution of ventricular systolic dysfunction in patients no systematic report. This study of community residents with heart failure patients ejection fraction,
