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.
