目的 :观察评价不同时期心肌梗死 (MI)患者经皮冠状动脉介入治疗 (PCI)后即刻疗效及远期疗效 .方法 :对1 988 0 4 / 2 0 0 1 1 2住西京医院的 4 5 5例经PTCA(经皮冠状动脉腔内成形术 )或 (和 )支架术并在术前已明确诊断的MI患者进行 1mo～ 8a的随访 .其中 6 9例为急性MI(AMI)后直接PCI或溶栓后补救性PCI;2 6 3例为AMI后 2mo内择期PCI和 1 2 3例陈旧性MI(OMI,MI时间大于 2mo)后的PCI.结果 :在 6 6例单纯球囊扩张术及 389例结合支架术或直接支架术中 ,手术成功率 98.5 % ,2例术中死亡 ,3例行冠状动脉旁路移植术 .382例随访 1mo ,无症状存活率 87.7% ,死亡 1 2例 .1 2 9例随访 2～ 8a ,无症状存活 5 2 .7% ,死亡 1 0例 .71例有症状复查冠脉造影中 ,30例发生再狭窄 .结论 :MI患者PCI即刻疗效好 ,远期无事件存活率 5 2 .7% ,AMI伴多支病变或心源性休克是术后早期死亡的主要原因 .大于 2mo以上的MI患者也能在PCI中获益
OBJECTIVE: To evaluate the immediate and long-term efficacy of percutaneous coronary intervention (PCI) in patients with myocardial infarction (MI) at different periods.Methods: A total of 985 patients were enrolled in this study, Patients with MI who had undergone PTCA (or percutaneous transluminal coronary angioplasty) or (and) stenting and who had a definite preoperative diagnosis were followed up for 1 to 8 years, of whom 69 were acute PCI (AMI) or PCI PCI after thrombolytic therapy and PCI after 2 6 3 cases of elective PCI and 123 cases of old MI within 2 months after AMI (OMI, MI time> 2 months) .Results: Sixty-six cases of simple balloon dilatation Among 389 patients who underwent stenting or direct stenting, the success rate of operation was 98.5%, 2 patients died during operation and 3 patients underwent coronary artery bypass grafting.3382 patients were followed up for 1 month, with asymptomatic survival rate of 87.7% and 12 deaths. One hundred and twenty-nine patients were followed up for 2 ~ 8 months, survival rate of asymptomatic patients was 52.7%, and death rate was 10% .There were 30 cases of restenosis in 71 cases with symptomatic review of coronary angiography.Conclusion: No incident survival rate of 52.7%, AMI with multiple lesions or cardiogenic shock is the main reason for early postoperative death.Mi patients more than 2mo above also in the PCI Profit
