目的　评价原发性冠脉内支架植入术治疗急性心肌梗塞的临床疗效。方法　 17例急性心肌梗塞患者于症状发作后 2～ 14小时施行冠脉内支架术。结果　所有患者冠脉再通均获成功。TIMI血流均达到 3级 ,无残余狭窄 ,血管再通距症状发作时间平均 5 7小时。所有患者胸痛均在术后 2小时内明显缓解 ;除 2例ST段持续抬高外 ,其余病例均在术后 2小时ST段下降 >5 0 % ;心肌酶峰明显提前。结论　急性心肌梗塞行原发性冠脉内支架术是安全有效的 ,可为梗塞相关血管提供更早期和有效的再通 Objective To evaluate the clinical efficacy of primary coronary stenting in the treatment of acute myocardial infarction. Methods Seventeen patients with acute myocardial infarction underwent coronary stenting 2 to 14 hours after the onset of symptoms. Results All patients had successful coronary recanalization. TIMI blood flow reached grade 3, no residual stenosis, auscultation of recanalization time average of 57 hours. Chest pain in all patients were significantly relieved within 2 hours after operation. Except ST-segment elevation in 2 patients, ST-segment drop was> 50% at 2 hours after operation, and myocardial enzyme peak was significantly advanced. Conclusions Primary coronary stenting in patients with acute myocardial infarction is safe and effective, providing an earlier and more effective recanalization of infarct-related blood vessels
