摘　　要：目的探讨对急性ST段抬高型心肌梗死（AMI）患者行急诊冠状动脉介入术（PCI）后ST段回落程度、T波早期倒置与心功能及预后的关系。方法ST段抬高型前壁AMI接受PCI患者62例，其中男40例，女22例。按PCI术后1hST段回落程度分两组：ST段回落≥50％组（A组，n=52），ST段回落〈50％组（B组，n=10）；按术后24hT波是否倒置再分为两组：倒置组（C组，n=47），未倒置组（D组，n=15）。观察A、B及c、D组6个月内左心功能改善的差异。结果A组、C组患者6个月内左心功能恢复优于B组、D组（P〈0．05）。结论AMI患者PCI再灌注治疗后对ST段和T波的分析是一种简便、实用的预测心功能的方法。Objective To explore the relationship between ST-segment level,T-wave early inversion and patients＇ left ventricular function, prognosis specifically for ST-segment elevation acute myocardial infarction patients, which underwent emergency PCI. Methods 62 patients （M ：40, F：22） with acute myocardial infarction were randomly divided into groups as follows：according to whether one hour ST segment＇s changes more than 50% after PCI, they were divided into group A and B：group A （PCI after one hour ST segment ≥50% ） ,group B （PCI ST segment after one hour 〈 50% ）. According to whether 24-hour T wave inversion after PCI,they were divided into group C and D： group C （24-hour T-wave inversion）, group D （24 hours without T wave inversion）. After six months, the different LVEF betweeen group A and B, C and D was observed. Results Of group A and group C, after 6 months, the left ventricular function recovery was better than that of group B and group D （P 〈 0.05 ）. Conclusion The analysis of ST segment and T wave are simple, practical and effective methods to predict myocardial reperfusion, especially for PCI therapy in patients with acute myocardial infarction.
