急诊经皮冠状动脉介入治疗急性心肌梗死的临床疗效评估

目的探讨地市级中心城市医院急诊经皮冠状动脉介入（percutaneous coronary intervention,PCI）治疗急性心肌梗死（acute myocardial infarction,AMI）的临床疗效及安全性。方法 45例发病12h以内AMI患者行直接PCI共置入支架49枚,观察梗死相关动脉（infarct related artery,IRA）再通率,住院病死率及主要不良心脏事件（major adverse cardiac event,MACE）发生率。结果支架置入成功率100%;达TIMIⅢ级血流IRA再通率88.9%;住院病死率2.2%;MACE发生率4.4%。结论地市级中心城市医院开展急诊PCI血管再通率高、病死率低、安全有效,能为更多基层AMI患者实行早期PCI治疗。

To discuss the efficacy and safety of emergent percutaneous coronary intervention in treatment of cases of acute myocardial infarction

Objective To discuss the efficacy and safety of emergency percutaneous coronary interventional in treatment of acute myocardial infarction in municipal hospital.Methods Forty-five cases of acute myocardial infarction patients within 12 hours of onset with direct coronary artery angiography and interventional treatment of infarct-related artery and insertion forty-nine stents.The patients were observed reperfusion rate of infarct related artery,hospital mortality and the incidence of major adverse cardiac events.Results The coronary recanalization rate was higher in emergency PCI group;Rate of success stent implantation was 100%.Reached TIMI Ⅲ grade flow IRA recanalization rate was 88.9%;hospital mortality was 2.2%;MACE rate was 4.4%.Conclusion Treated with emergency intervention in acute myocardial infarction had higher vascular recanalization,lower mortality,and was safe and effective in municipal hospital.More AMI patients in primary areas would be treated with early PCI.
