【摘 要】目的：急性心梗后早期血运重建是挽救缺血心肌最有效的治疗方法，评价直接冠状动脉介入术(PCI)后再灌注指标与AMI患者心功能及预后的关系对临床有指导意义。心电图演变是常用的再灌注指标，直接PCI术可加速ST段和T波演变。本研究是为明确对急性ST段抬高型心肌梗死患者行急诊PCI术后ST段回落程度及T波早期倒置与心功能及预后的关系。结果：A组(PCI术后1小时ST段回落≥50%组)和C组(24小时T波倒置组)患者6月内左心功能恢复优于B组(PCI术后1小时ST段回落<50%组)、D组(24小时T波未倒置组)，(P<0.05)。结论：急性心肌梗死患者PCI再灌注治疗后对ST段和T波的分析是一种简便、实用的预测心肌水平有效再灌注的方法。

    【Abstract】Objective：Early revascularization after acute myocardial infarction(AMI) is the effective way to save ischemic myocardium. Evaluation of myocardial reperfusion sign after direct coronary intervention (PCI) in patients with AMI, then compare with accordingly patients’ left ventricular function and prognosis, which make sence of clinical work. Electrocardiogram evolution is a common to evaluate myocardial reperfusion, direct PCI can accelerate ST-segment and T-wave evolution. This study is to find the relation ship between ST-segment level, T-wave early inversion and patients’ left ventricular function, prognosis specifically for ST-segment elevation acute myocardial infarction patients, which undergoing emergency PCI. Results：Group A (PCI after one hour ST segment ≥ 50%) and group C (24-hour T-wave inversion) , after 6 months, we found these patients left ventricular function recovery better than group B (PCI ST segment after one hour <50 %)and group D (24 hours without T wave inversion), (P <0.05).Conclusion：The analysis of ST segment and T wave are simple, practical and effective methods to predict myocardial reperfusion, expecially for PCI therapy in patients with acute myocardial infarction. ......
