摘要
目的:观察急性心肌梗死(AMI)溶栓后心电图早期ST段变化对预后的影响。方法:对70例AMI患者溶栓前及溶栓后2h心电图(ECG)ST段进行分析,根据溶栓前后ST段下降的不同程度分组,观察ST段下降>70%组、下降30%～70%组及下降<30%组的心肌酶(CK-MB)释放规律。结果:ST段下降<30%组,CK-MB峰值时间明显长于其它两组,CK-MB最大含量明显高于ST段下降≥70%组。结论:心电图早期ST段变化可作为AMI患者溶栓治疗预后的重要指标。
Objective： To investigate the effect of early ST-segment analysis to predict the prognosis of patients with acute myocardial infarction treated with venous urokinase.Methods： The ST-segment changes on electrocardiogram were studied in 70 patients with acute myocardial infarction before thrombolysis and 2 hours thereafter.Patients were defined as 3 groups： the resolution of ST-segment≥70%（n=19,group A）,from 30% to 70%（n=27,group B）,and 30%（n=24,group C）by the frequency analysis 2 hours after thrombolytic therapy.Results： In group C,the duration to reach peak creatine kinase（CK-MB）in myocardial origin after the onset of symptoms was significantly longer than that in the rest 2 groups（P0.05）and the maximal CK-MB value was bigger than that of group A.Conclusion： Early ST-segment analysis might be used as a tool for assessing the prognosis of patients with acute myocardial infarction after treatment with venous urokinase.
