目的：评价冠状动脉内支架治疗急性心肌梗死（ＡＭＩ）的效果。方法：对４８例植入支架的ＡＭＩ连续病例进行回顾性分析。结果：心肌梗死相关血管为：前降支３３例，右冠状动脉８例，回旋支４例，左主干１例以及大隐静脉桥２例。４８例患者共植入５７只支架，其中３４例因球囊扩张后结果不理想，１２例因非闭塞性夹层，２例因闭塞性夹层。支架植入成功率为９３８％，术后残余狭窄降至（２４±７１）％。院内严重并发症３例，其中１例（２１％）死亡，２例（４２％）行急诊冠状动脉旁路移植术。对无院内并发症的４５例患者随访１０．１±７２个月，其中３例失访，出院后２例发生再狭窄和１例有慢性充血性心力衰竭，无其它心脏事件发生。结论：本研究结果表明ＡＭＩ时冠状动脉内植入支架成功率高，并发症少，短期预后良好 Objective: To evaluate the effect of intracoronary stents in the treatment of acute myocardial infarction (AMI). Methods: A retrospective analysis of 48 consecutive cases of AMI with stent implantation. Results: The blood vessels related to myocardial infarction were: anterior descending branch in 33 cases, right coronary artery in 8 cases, circumflex artery in 4 cases, left main trunk in 1 case and saphenous vein bridge in 2 cases. Forty-seven stents were implanted in 48 patients, 34 of whom had unsatisfactory results due to balloon dilatation, 12 due to non-occlusive dissection and 2 due to occlusive dissection. The successful rate of stent implantation was 93.8%, and the residual stenosis decreased to (24 ± 71)%. There were 3 severe complications in the hospital, of which 1 died (21%) and 2 cases (42%) underwent emergency coronary artery bypass grafting. Forty-five patients without nosocomial complications were followed up for 10.1 ± 7.2 months, of whom 3 were lost to follow-up, 2 had restenosis after discharge and 1 had chronic congestive heart failure. No other cardiac events occurred. CONCLUSIONS: The results of this study indicate that AMI has a high success rate of coronary stent implantation with fewer complications and a good short-term prognosis
