目的 为探讨冠状动脉内支架治疗急性心肌梗塞的可行性和安全性。方法 对４６ 例经球囊扩张后效果不理想的急性心肌梗塞（ＡＭＩ）患者行冠脉内支架置入。其中男３８ 例，女８ 例，平均年龄为５６．２ 岁。全部采用球囊扩张法置入支架。结果 ４６ 例患者术前梗塞相关血管均为ＴＩＭＩ３ 级血流，经置入冠脉内支架后梗塞血管均恢复ＴＩＭＩⅢ级血流，血管开通率１００％ 。８ 例球囊扩张后见冠脉内有残余血栓，置入支架后消失，造影未发现血栓进入远端血管；１ 例患者因Ⅲ°ＡＶＢ 给以临时起搏治疗，术后 ６小时因临时起搏电极刺破右室所致心包填塞死亡。其余 ４５ 例患者在４～３８ 个月的随访中均未发生死亡，无梗塞后心绞痛及再次心肌梗塞，６ 例患者于术后４ 周行冠脉造影复查，原支架置入处血流通畅，无管腔再狭窄。结论 冠脉内支架置入是急性心肌梗塞患者一个安全而有效的治疗方法
Objective To investigate the feasibility and safety of coronary stent in the treatment of acute myocardial infarction. Methods 46 patients with acute myocardial infarction (AMI) who did not achieve satisfactory results after balloon dilation were treated with coronary stent implantation. There were 38 males and 8 females, with an average age of 56.2 years. All using balloon dilation method into the stent. Results All 46 patients had TIMI grade 3 blood flow, and TIMI grade Ⅲ blood flow was recovered after implantation of coronary stent. The rate of vascular opening was 100%. 8 cases of balloon dilatation see residual coronary thrombosis, stent disappeared, angiography did not find the thrombus into the distal blood vessels; 1 patient due to Ⅲ ° AVB to temporary pacing treatment, 6 hours after the temporary Electrocardiogram pierced the right ventricle caused by cardiac tamponade. The remaining 45 patients were followed up for 4 to 38 months without death, no post-infarction angina and re-myocardial infarction, 6 patients underwent coronary angiography at 4 weeks postoperatively, the original stent placement blood flow smooth, no tube Restenosis. Conclusion Coronary stenting is a safe and effective treatment for patients with acute myocardial infarction
