目的 探讨缺血性心肌病 (ICM)的临床特点。方法 对诊断为 ICM的 46例患者的临床资料进行回顾性分析。结果 46例患者均有心绞痛、心肌梗死的冠心病史 ;以老年男性多见 (80 .4% ) ;心脏扩大、心力衰竭和心律失常为主要临床表现 ;超声心动图多数显示左心室扩大 ,室壁运动呈节段性运动异常 ,左心室射血分数平均 <45 % ;选择性冠状动脉造影呈 1支或多支血管病变 ,血管狭窄平均 >75 % ,甚至完全闭塞。结论 ICM以老年男性多见 ,临床以心脏扩大 ,充血性心力衰竭为主要表现 ,酷似扩张型心肌病 ,冠状动脉造影是可靠的鉴别诊断方法。介入治疗是目前治疗 ICM较好的方法
Objective To investigate the clinical features of ischemic cardiomyopathy (ICM). Methods The clinical data of 46 patients diagnosed as ICM were retrospectively analyzed. Results All 46 patients had history of angina pectoris and myocardial infarction. Coronary heart disease was common in elderly men (80.4%). Cardiac enlargement, heart failure and arrhythmia were the main clinical manifestations. Most of the echocardiograms showed left ventricular enlargement, Segmental wall motion was segmental abnormalities, left ventricular ejection fraction averaged <45%; selective coronary angiography was 1 or more vascular disease, vascular stenosis averaged> 75%, or even completely occluded. Conclusion ICM is more common in elderly men, the clinical manifestations of heart enlargement, congestive heart failure as the main performance, exactly like dilated cardiomyopathy, coronary angiography is a reliable differential diagnosis. Interventional therapy is currently a better method of treatment of ICM
