急性心肌梗死95例的临床特征

目的 总结分析我科近年收治的急性心肌梗死病人，提高对该病的深入认识及救治水平。方法 收集1998年1月～2001年2月急性心肌梗死病人95例，对其临床特征加以分析。结果 患病年龄在40岁以上者约97％，男女之比约为4．0：1。急性前壁心肌梗死占45％，急性下壁心肌梗死(AIMI)约占38％，急性前间壁心肌梗死占8％。Q波心肌梗死约占91％，非Q波心肌梗死约占9％。80％病人出现胸痛，26％有心力衰竭，15％并有心房纤颤。Ⅲ度AVB在AIMI中的发生率约34％。治愈率约76％，好转率10％，死亡率约7％。结论 急性心梗好发于40岁以上男性，胸痛多见，前壁梗死近半数病人，部分出现并发症，以静脉溶栓为主的综合治疗能获得满意的治愈率。

ClINICAL CHARACTERISTICS OF 95 PATIENTS WITH ACUTE MYOCARDIAL INFARCTION

Objective To summarize and analyze clinical characteristics of patients with acute myocardial infarction（AMI）admitted in the Department of Cardiology from Jan of 1998 to Feb of 2001 as to get much improvement on diagnosis and treatment of AMI.

Ⅲ degree atrioventricular block was about 34%(12/35) in patients with AIMI. There were 86%(83/95) of survival rate and about 7%(7/95) of mortality in 95 patients. Conclusions More patients with AMI occured in male of over 40 years old. Chest pain was main manifestation in most AMI patients and some patients were complicated with heart failure,arrhythmia and other complications.
