目的探讨急诊冠脉介入治疗(PCI)急性心肌梗死的临床效果及安全性。方法对急诊入住我院的40例急性心肌梗死患者(发病6小时内或不超过12小时仍有胸痛及心电图ST段抬高)行急诊PCI术,观察梗死相关血管(IRA)开通成功率、(TIMI)级血流及无复流现象的发生率、住院病死率。结果IRA开通成功率为98.7%,达TIMI级血流37例(92.5%),无复流者1例(2.5%),1例术中死亡,1例前降支开口病变择日行了搭桥术。出院时左心室排血分数平均58%。住院病死率2.5%。结论急性心肌梗死时行急诊PCI,成功率高,能够降低病死率,疗效显著且安全。 Objective To investigate the clinical effect and safety of emergency percutaneous coronary intervention (PCI) in acute myocardial infarction. Methods Forty patients with acute myocardial infarction admitted to our hospital underwent emergency PCI during 6 hours or no more than 12 hours after onset of chest pain and electrocardiogram ST segment elevation. The success rate of IRA was observed. TIMI) grade blood flow and no-reflow phenomenon, in-hospital mortality. Results The success rate of IRA was 98.7%, TIMI grade blood flow was 37 (92.5%), no recurrence was found in 1 case (2.5%), one case died and one case of anterior descending artery open Surgery. Left ventricular ejection fraction average 58%. In-hospital mortality was 2.5%. Conclusions Emergency PCI during acute myocardial infarction has a high success rate and can reduce the mortality rate. The curative effect is significant and safe.
