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。
Objective: To investigate the clinical effect of percutaneous coronary intervention (PCI) in the treatment of acute ST-segment elevation myocardial infarction (STEMI). Methods: The clinical data of 165 patients with acute myocardial infarction (AMI) were summarized. Results: Of the 165 patients with AMI, 45 (27.3%) had single-vessel disease, 49 (29.7%) had double-vessel disease, and 71 (43.0%) had three or more lesions. 165 patients underwent PCI, the success rate of 98.8%, a total of 205 stent placement. There were 90 cases (54.5%) of infarction-related artery with stent placement in 112 cases. LCX was found in 21 cases (12.7%) with stent placement in 23 cases. Right coronary artery (RCA) in 54 cases (32.7%), placed in stent 70. There were 18 patients (10.9%) with cardiogenic shock before PCI, and 2 patients died after operation. Conclusion: Percutaneous coronary stent implantation in acute myocardial infarction is effective.
