目的　探讨溶栓治疗急性心肌梗死 (AMI)开始时间对疗效和预后的影响 .方法　将 99名AMI患者分为急诊组 (30例 )、内科病房组 (36例 )和对照组 (33例 ) ,比较栓塞冠状动脉再通率 ,住院期间心脏及其它并发症 .结果　溶栓后再通率急诊组为 86 .7%、病房组为 6 6 .7% ;心脏性死亡率急诊组为 3 .3%、内科病房组为 8.3 % ,明显低于对照组 (18 2 % ) .结论　急诊溶栓治疗能显著提高AMI患者的急性期疗效和改善预后 Objective To investigate the effect of thrombolytic therapy on the curative effect and prognosis of acute myocardial infarction (AMI) .Methods 99 AMI patients were divided into emergency group (30 cases), medical ward group (36 cases) and control group (33 cases) The rate of recanalization of coronary artery during embolization and heart and other complications during hospitalization were compared.Results The rate of recanalization after thrombolysis was 86.7% in the emergency department and 6.6% in the ward and 6.3% in the cardiac emergency group %, 8.3% in the medical ward group, significantly lower than that in the control group (18.2%) .Conclusion Emergency thrombolytic therapy can significantly improve the acute phase of AMI patients and improve prognosis
