ST段再抬高对急性心肌梗死溶栓患者近期预后的影响

Influence of ST segment re-elevation on the recent prognosis posterior to acute myocardial infarction

目的:探讨急性心肌梗死(AMI)静脉溶栓治疗后ST段再抬高对患者近期预后的影响。方法:将首发98例患者按静脉溶栓治疗后心电图有无ST段再抬高分为ST段再抬高组(A组)和ST段无再抬高组(B组),比较两组危险因素、再灌注心律失常、心功能、梗死后心绞痛及并存疾病等。结果:两组伴发糖尿病、原发性高血压及吸烟比较,无统计学意义(P>0.05);两组梗死部位、再灌注心律失常、心功能分级、梗死后心绞痛比较,无统计学意义(P>0.05)。结论:AMI静脉溶栓治疗后短暂的ST段再抬高可作为心肌再灌注成功的一种临床表现,对患者近期预后无不良影响。

Objective： To explore the influence of ST segment re-elevation on the recent prognosis posterior to AMI. Methods： 98 patients were divided into two groups： ST segment re-elevation group （A group） and none-ST segment re-elevation group （B group）. Cardiac arrhythmia after reperfusion, heart function, postinfarction angina pectoris and complications were analyzed in two groups. Results： There were no difference of concomitant diabetes mellitus, essential hypertension, smoking rate between two groups （P 〉 0.05）. Cardiac arrhythmia after reperfusion, cardiac function grade, postinfarction angina pectoris were compared in two groups, but there were no difference between two groups （P 〉 0.05）. Conclusion： Transient ST segment re-elevation after intravenous throm-belytic therapy in patients with AMI could be considered as one clinical performance of successful reperfusion of myocardium, which has no negtive influence on the recent prognosis posterior to AMI.
