缺血性心肌病的临床特点(附28例分析)

Clinic features of is chemic cardiomyopathy

目的 探讨缺血性心肌病的临床特点。方法 对诊断缺血性心肌病 2 8例患者的临床资料进行回顾性分析。结果 大多数患者是老年人 ,均有心绞痛、心肌梗死病史 ;心脏扩大 ,心力衰竭和心律失常为主要临床表现 ;U CG呈现左室扩大 ,室壁节段性运动异常 ,左心室射血分数 (L VEF) <4 5 % ;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 缺血性心肌病多见于老年人 ,以心脏扩大 ,充血性心力衰竭为特征 ,酷似扩张型心肌病 ,冠状动脉造影是可靠的鉴别诊断方法。必要时可考虑冠状动脉搭桥或心脏移植术。

Objective To explore the clinic features of ischemic cardiomyopathy.Method Analyses of clinical material were performed in 28 cases with is chemic cardiomyopath.Resulf most patients were the senile pelple;All patients has a history of angina pectoris or myocardial infarction;the main clinical manifestations were heart dilation,various kinds of cardioarrhy thmia and heart failure;UCG vevealed left ventricle dalation segmental abnormality of ventricular wall motion and declining in left ventricular ejection fraction (<45%);coronary angiography demonstrated 1-vessel or more than 1-vessel diseases,coronary stenoses>75%,even complete occlusion.Conclusion this illness ususlly occurs in the senile pelple,the clinical characteristics were heart dilation and congestive heart failure and similar to dilated cardiomyopathy;coonary angiography is a reliable mothod for its differential diagnosis,and angioplasty is an effective treatment means at present.When necessar,coronary arery hypass grafring and cardiac transplantation my be considered.
