目的:对缺血性心肌病(ICM)的临床特征进行分析和探讨。方法:对确诊的ICM 16例患者的临床进行分析总结。结果:患者年龄大,部分有心绞痛,心肌梗死病史;慢性心力衰竭为主要临床表现;心脏扩大明显,并可伴发各种心律失常;超声心动图呈现左心扩大,室壁节段性运动异常,左心室射血分数减少(<35%);选择性冠状动脉造影显示多支血管病变,血管狭窄平均>75%,甚至完全闭塞。结论:老年缺血性心肌病以心脏扩大、慢性顽固性心力衰竭为特征。酷似扩张型心肌病。冠状动脉造影是可靠的鉴别诊断方法。目前药物治疗只能缓解和改善症状,心脏介入治疗有一定效果,许多治疗方法值得关注。
Objective: To analyze and discuss the clinical features of ischemic cardiomyopathy (ICM). Methods: The clinical data of 16 patients diagnosed with ICM were analyzed and summarized. Results: The patients were older, partially angina and had a history of myocardial infarction. Chronic heart failure was the main clinical manifestation. The heart enlarged obviously and could be associated with various arrhythmia. Echocardiography showed left ventricular enlargement and segmental wall motion abnormalities , Left ventricular ejection fraction decreased (<35%); selective coronary angiography showed multivessel disease, vascular stenosis averaged> 75%, or even completely occluded. Conclusion: Elderly ischemic cardiomyopathy is characterized by enlarged heart and chronic refractory heart failure. Similar to dilated cardiomyopathy. Coronary angiography is a reliable differential diagnosis. The current drug treatment can only alleviate and improve symptoms, cardiac interventional therapy has some effect, many treatments deserve attention.
