摘　　要：对85例左室射血分数正常心力衰竭患者（HFNEF组）与89例左室射血分数减低心力衰竭患者（HFREF组）的危险因素、临床特征以及肺CT表现进行比较分析.结果显示,HFNEF组患者较HFREF组患者既往有高血压、糖尿病、肥胖者比例高;咳嗽、呼吸困难常见;肺部CT表现以肺纹理增多、增重,出现胸膜下线、克氏线以及肺实质磨玻璃样变等间质性肺水肿改变为主.而HFREF患者中冠心病者比例较高,临床以急性左心衰表现为主,肺CT表现以肺泡性肺水肿为主.提示HFNEF组患者临床病史较长,症状隐匿,肺部CT表现有别于HFREF组患者.The clinical features and lung CT findings of 174 heart failure patients,including 85 cases with normal left ventricular ejection fraction （LVEF） and 89 cases with reduced LVEF were reviewed.Patients with normal LVEF had a higher proportion of hypertension,diabetes and obesity than patients with normal LVEF; and cough and dyspnea were more common.The lung CT findings in patients with normal LVEF were frequently presented as interstitial lung edema,increased pulmonary texture,subpleural line,Kerley lines and diffuse ground-glass opacity.Patients with reduced LVEF had a higher proportion of coronary heart disease and clinical manifestations of acute left heart failure,and central alveolar edema presented in lung CT images.Results suggest that heart failure patients with normal LVEF usually have longer clinical history and occult symptoms,and have a different lung CT imaging features from those in heart failure patients with reduced LVEF.
