射血分数保留的心力衰竭患者临床特点及治疗方法探讨

目的探讨射血分数正常的心力衰竭（HFNEF）患者的临床特点及治疗。方法采取抽样的方法选择我院心内科2005～2010年1240例心力衰竭患者，筛选出572例分为LVEF≥50％组及LVEF〈50％组。结果LVEF≥50％与LVEF〈50％的患者相比，HFPEF患者年龄更大，女性及高血压更多；陈旧性心梗、扩张性心肌病、房颤及急性心力衰竭比例均低于对照组，有统计学差异。结论HFPEF存在收缩功能减低，不完全等同于舒张功能下降的心力衰竭（DHF）。早期干预对延缓及阻止HFPEF的发生进展至关重要。

Clinical Characteristics and Treatment of Heart Failure Patients with Preserved Ejection Fraction

Objective To investigate clinical characteristics and management in patients with heart failure with preserved ejection fraction （ HFPEF ） in China. Method There were 1240 patients with heart failure from 2005 to 2010 using the cluster sampling method. According to the selected conditions, the clinical data of 572 patients with heart failure （ NYHA Class Ⅲ-Ⅳ）were analyzed retrospectively. And according to EF derived from echocardiography. Result To compare with patients with systolic dysfunction （ EF 〈： 50% ）, patients with HFPEF were more likely to be older, more women and hypertensive. Conclusion The patients with HFNEF exist systolic function to decrease, are not completely equal to diastolic function decline of heart failure （ DHF ）. So HFPEF incidence of may increase the risk factors for early intervention, in order to delay or prevent the occurrence of HFPEF.
