梗死前心绞痛对急性心肌梗死溶栓治疗及近期预后的影响

Affection of Angina Pectoris before Infarction to Thrombolytic therapy of Acute Myocardial Infarction in Short Term Prognosis

目的 探讨梗死前心绞痛对急性心肌梗死溶栓治疗及近期预后的影响。方法 本文将 98例急性Q波心肌梗死病人 ,按梗死前 4 8h内心绞痛的有无 ,分为AP( +)和AP( - )组 ,分别观察两组溶栓再通率、CPK峰值、达峰时间、坏死Q波导联数、住院期间心力衰竭、恶性心律失常、心源性休克的发生率、病死率 ,出院时室壁瘤及左室射血分数。结果 两组均有显著性差异。结论 梗死前心绞痛对急性心肌梗死有潜在的治疗意义 ,可影响预后。

Objective: To discuss the affection of angina pectoris (AP) before infarction to thrombolytic therapy of AMI in short terms prognosis. Methods: 98 cases of AMI patient with Q wave were divided into two groups (AP+ and AP-) according to whether there was AP or not within 48h before infarction. The many clinical data were observed (such as CPK peak, leads of pathogenic Q wave, occurrence of cardiac shock, mortality and so on). Results: There were significant differences between two groups. Conclusion: AP before infarction might have latent action of treatment for AMI and could improve the prognosis.
