ST段再抬高对急性心肌梗死溶栓患者近期预后的影响

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。

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

Objective:To explore the influence of ST segment re-elevation on the recent prognosis posterior to AMI.Metho-ds: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-bolytic 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.
