摘　　要：目的:探讨急性心肌梗死直接PTCA术后1小时ST段变化对急性期预后的评估意义。方法:观察2001年1月-2003年10月因首次患急性前壁心肌梗死在我院接受直接PTCA的病人54例。比较PTCA术前、术后1小时ST段的高度。按抬高的ST段下移>50%或<50%,分为A组(33例)和B组(21例)。结果:住院期间死亡例数,A组1例,B组2例;心功能Ⅲ-Ⅳ级的病例:A组4例(4/32.12.5%),B组8例(8/19,42.1%).P<0.05。左室射血分数:A组(51.5±8.76)%,B组(44.82±8.04)%,P<0.01。结论:急性心肌梗死直接PTCA术后1小时ST段变化,反映心肌再灌注后的微循环情况,是预测早期临床预后和检出高危患者的简便而可靠的方法。Objective: To study the significance of resolution of ST segment elevation one hour after primary PTCA in acute myocardial infarction (AMI). Methods: Fifty four patients with AMI after primary PTCA were divided into two group by comparing the ST segment elevation before and after primary PTCA one hour: group A (33 cases), the resolution of ST segment elevation>50% ;group B(21 cases), the resolution of ST segment elevation<50%. Results: The number of mortality was 1 case in group A and 2 in group B. The number of patients with Ⅲ-Ⅳ Killip degree was 1 in group A (4/32. 12. 5%) and 8 in group B (8/19. 42. 1%). P<0. 05. LVEF was (51. 5 ±8. 76)% in group A and (44. 82±8.04)% in group B. P<0. 01. Conclusion: The change of ST segment elevation after primary PTCA one hour reflect the macro-circulation condition after reperfusion. It is a convenient and reliable method predicting acute prognosis and discovering the high risk patient.
