基层医院急诊冠状动脉介入治疗急性心肌梗死的临床应用研究

目的 分析急诊行经皮冠状动脉介入治疗(PCI)急性ST段抬高心肌梗死(STEMI)患者的即刻和随访结果,以评价在具备条件的基层医院开展急诊PCI的可行性.方法 1998年6月至2005年12月对122例STEMI患者经股动脉行急诊PCI治疗,其中119例直接PCI,3例补救PCI.结果 血管造影成功率95.1%,操作成功率93.4%.5例应用了主动脉球囊反搏术,2例发生支架内亚急性血栓形成,住院死亡5/122例(4.1%),术后1周内行超声心动图检查测左心室射血分数(LVEF):(0.55±0.16).平均住院天数(9.5±5.8(1～36)d.6个月死亡7/122例(死亡率5.7%).结论 直接PCI可迅速使梗死相关动脉开通并恢复正常血流,扩大了治疗STEMI的适应证,高危患者术后存活率高,住院时间缩短.补救性PCI是静脉溶栓治疗失败后的一种有效补救措施.在具备条件的基层医院开展急诊PCI安全、可行.

Clinical application of emergency percutanous coronary intervention in the treatment of acute myocardial infarction

Objective To analyze the immediate and following up result of 122 patients with acute myocardlal infarction(AMI)which underwent emergency percutaneous coronary interventlon(PCI).Methods 122 cases of AMI patients underwent the emergency PCI by transfemoral artery approach during June 1998 to December 2005.119 casea performed primary PCI,3 performed rescue PCI.Results The successful rate of vessel visualization and operation were 95.1%.93.4%.respectively.5 eases were with the help of intra-aortic balloon pumping.Subacute instent thrombosis occurred in 2 patients.In-hopital mortality was 4.1% (5/122).The left ventricular ejection fraction in echocardiography one after week was(0.55±0.16).Average hospital day is(9.5±5.8)(1～36).6-month mortality was 5.7%(7/122).Conclusion Primary PCI expanded the indication for the treatment of STEMI patients wlth establishment of patent infarct related artery and normal blood flow,increased tlle survival of high-risk patients,and shortened the hospitalization.Rescue PCI was an effective measure for the patients failing to intravenous thrombolysis.
