直接冠状动脉内支架置入治疗急性心肌梗塞31例临床报告

摘要

Objective To evaluate the efficacyand safety of primary intracoronary stenting in acute myocardial infarction(AMI).Methods 31 AMI patients(24 males and 7 females, mean age 64.9 years) who underwent primary intracoronary stenting were analyzed. Results After operation, all 31 patients' blood flow wer successfully restored from TIMI 0 grade to TIMI 3 grade. Residual stenosis decreased to 5％～10％ . No death occurred amgong the 9 patients whose age was over 70. Among the 6patients with cardiogenic shock, only one patient had irreversible heart failure and died. During the 1～21 monhts follow－up period of the other 30 patients, no death or heart event happened. Conclusion Primary intracornary stenting was an efficient therapeutic procedure to AMI patients, especially to those with high risks.%目的探讨直接冠状动脉内支架治疗急性心肌梗塞的疗效和安全性。方法对31例急性心肌梗塞（AMI）行直接冠状动脉内支架置入病例进行分析。其中男24例，女7例，平均年龄为64.9岁。结果31例患者术前梗塞相关血管均为TIMI0级血流，经置入冠脉内支架后梗塞相关血管均恢复TIMIⅢ级，残余狭窄为5％～10％，血管开通率为100％。9例年龄超过70岁患者无一死亡，并且没发生严重的并发症；6例心源性休克除1例心源性休克不可逆转而发生电机械分离抢救无效死亡外，其余5例顺利恢复。30例患者在1～21月随访中均未发生死亡，无心脏事件发生。结论冠脉内支架置入是治疗急性心肌梗塞安全有效的方法，能明显降低高危患者的死亡率。
