目的 :评价直接冠脉内支架植入术治疗急性心肌梗死的临床疗效。方法 :17例急性心肌梗死患者于症状发作后 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。 1例左主干病变于术后 1周发生严重泵衰竭死亡 ;术后随访 2～ 18个月 ,有 3例 (18.75 % )复发心绞痛 ,2例再次行经皮冠脉腔内成形术(PTCA) ,无死亡病例。结论 :急性心肌梗死行直接冠脉内支架术是安全有效的 ,可为梗死相关血管提供更早期和有效的再通
Objective: To evaluate the clinical effect of direct 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: Coronary artery recanalization was successful in all patients. TIMI blood flow reached grade 3, no residual stenosis, auscultation of recanalization symptoms average time of 5.7 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. One case of left main disease died of severe pump failure one week after operation. The patients were followed up for 2 to 18 months. Three patients (18.75%) had recurrent angina pectoris, and two patients underwent percutaneous transluminal coronary angioplasty (PTCA) No deaths. CONCLUSIONS: Direct coronary stenting in patients with acute myocardial infarction is safe and effective, providing an earlier and more effective recanalization of infarct-related blood vessels
