【摘要】 目的：探讨急性前壁Q波型心肌梗死（AMI）患者左心室重塑（LVRM）和左心室收缩功能（LVSF）。方法：将140例AMI患者随机分为静脉溶栓组和非溶栓组。采用Doppler超声心动图仪进行监测。结果：140例AMI患者LVRM总发生率为42．1％。溶栓组LVRM发生率明显低于非溶栓组（P＜0．05）。LVRM对LVSF产生明显影响。溶栓再通组LVRM发生率明显低于未再通组（P＜0．01），且LVSF明显得到改善（P＜0．01）。结论：AMI患者的LVRM发生率高，对LVSF有明显的影响。早期实施静脉溶栓治疗能减少LVRM发生，改善LVSF。更多还原

【Abstract】 Aim: To study the left ventricular remodeling (LVRM) and left ventrivcular systolic function (LVSF) in patients with acute myocardial infarction(AMI). Method: 140 patients with acute Q-type anterior myocardial infarction≤6 hours were randomly divided into thrombolysis group and non-thrombolysis group. LVRM and LVSF were studied and analysed using Doppler echocardiography. Results: The incidence of LVRM was 42.1% in 140 patients with AMI. The effect of LVRM on LVSF was obviously. In comparision with non-thrombolysis group, the incidence of LVRM was significantly decreased in thrombolysis group (p<0.05); in comparision with non-reperfusion group, the incidence of LVRM was significantly decreased (p<0.01) and LVSF was significantly improved (p<0.01) in reperfusion group. Conclusions: The incidence of LVRM high developed after AMI can affect LVSF markedly. The early intravenous thrombolysis can reduce LVRM and improve LVSF.[更多还原
