目的 :评价链激酶溶栓治疗老年急性心肌梗塞 (AMI)对左心室功能的影响.方法 :应用二维超声心动图对 2 9例 AMI接受链激酶溶栓治疗和 2 1例未溶栓的 AMI患者 ,分别在急性期及 6个月后随访时测量并计算左心室容积 (EDV和 ESV) ,射血分数 (EF)等参数.结果 :急性各组心功能无差异.随访期再通组 EF值明显增加 ,且明显高于未通组和未溶栓组.结论 :链激酶溶栓能明显减轻老 AMI患者的左心室扩张 ,改善左心室功能和长期预后“,”Objective:The aim of this study was to assess the effects of reperfusion by streptodinase thrombolytic therapy on left ventricular function.Methods:29 elderly patients with first acute myocardial infarction(AMI) receiving thrombolytic therapy were divided into reperfusion group,non reperfusion group according to the clinical characteristics.21cases with AMI not receiving thrombolytic therapy was control group.Results:EF was significantly improved during follow up in reperfusion group and higher than that in non reperfusion( P <0 01).Conclusion:The results suggest that reperfusion with thromblysis after AMI can improve heart function and prognosis.
