急性心肌梗死并左心室功能减低的临床特征分析

Clinical features analysis of reduced left ventricular function complicated with acute myocardial infarction

目的分析急性心肌梗死(AMI)并左心室功能减低的临床特征,为AMI的救治提供依据。方法116例患者,分为心功能正常组(69例)与异常组(47例),对比分析2组患者一般情况、既往史及临床特征。结果2组患者性别比、吸烟、高血压病、高脂血症、冠心病病史差异无统计学意义,心功能异常组年龄高于正常组,心功能异常组中糖尿病患者明显多于心功能正常组。2组心肌梗死部位比较,心功能异常组前壁心肌梗死比正常组更常见,心功能异常组CK峰值及CK-MB峰值均显著高于心功能正常组。心功能异常组急性肺水肿、心原性休克、心律失常和病死率均明显高于心功能正常组。结论AMI患者如年龄大、有糖尿病病史,前壁心肌梗死且梗死面积大者,易并发左心功能异常,心功能异常患者并发症发生率及病死率增高,应引起高度重视。

Objective To analyse clinical features of reduced left ventficular function complicated with acute myocardial infarction （AMI）for guiding the treatment of AMI. Methods One hundred and sixteen patients with AMI were divided into two groups：normal cardiac function group（69 eases）and abnormal cardiac function （47 eases）for comparing their clinical features. Results There were no difference of gender, smoking, the history of hypertention, hyperlipemia, coronary heart disease between the two groups. The age and the incidence of diabetes in abnormal group were higher than that in normal group. Anterior infarction was more common in abnormal group. CK peak and CK-MB peak were more higher in abnormal group. The incidence of acute pulmonary edema,eardiogenie shock,arrhythmia,and mortality were more higher in annormal group. Conclusions AMI patients with older age, diabetes history, anterior wall AMI, a large size infarction are related to reduced left ventricular function, and the incidence of complication and the mortality are more higher, therefore more attention must be payed.
