经皮冠状动脉内支架置入术治疗急性心肌梗死165例的效果

目的：探讨经皮冠状动脉内支架置入术（PCI）治疗急性ST段抬高型心肌梗死（STEMI）的临床疗效。方法：总结165例急性心肌梗死（AMI）患者的PCI临床资料。结果：入选的165例AMI患者中单支病变45例（27．3％），双支病变49例（29．7％），三支或三支以上病变71例（43．0％）。165例患者行PCI，成功率98．8％，共置入支架205枚。梗死相关血管为前降支（LAD）90例（54．5％），置入支架112枚；左回旋支（LCX）21例（12．7％），置入支架23枚；右冠脉（RCA）54例（32．7％），置入支架70枚。PCI术前出现心源性休克者18例（10．9％），2例于术后死亡。结论：急性心肌梗死行经皮冠状动脉内支架置入术疗效肯定。

Effect of percutaneous coronary intervention in 165 patients with acute myocardial infarction

Objective:To study clinical effects of percutaneous coronary intervention(PCI) in patients with acute ST elevation myocardial infarction(STEMI).Methods:The clinical data of 165 cases with acute myocardial infarction(AMI) undergoing PCI were annlyzed.Results:Among 165 patients,there were 45 patients(27.3%) with single vessel coronary disease,49 patients(29.7%) with double vessel coronary disease and 71 patients(43.0%) with triple or more vessel coronary disease.A total of 165 patients were performed PCI and success rate was 98.8%.For infarct-related artery,90 cases(54.5%) were left anterior descending artery(LAD) and 112 stents were implanted;21 cases(12.7%) were left circumflex coronary artery(LCX) and 23 stents were implanted;54 cases(32.7%) were right coronary artery(RCA) and 70 stents were implanted.A total of 18 patients(10.9%) occurred cardiogenic shock before PCI and in which two patient died because treatment failure.Conclusion:Percutaneous coronary intervention is safe,effective for patients with acute myocardial infarction.
