目的：探讨冠状动脉内支架置入治疗急性心肌梗塞（ＡＭＩ）的可行性和安全性。方法：对４３例ＡＭＩ患者行冠脉内支架置入。其中男３５例，女８例，年龄４０～８８岁，年均（６０．９±１０．１）岁。结果：４３例患者经置入冠脉内支架后阻塞血管均复通，恢复血流ＴＩＭＩ３级。４３例患者住院５～４９ ｄ，平均（１８．１±９．１）ｄ。其中１例前壁ＡＭＩ患者术后１周再发侧壁ＡＭＩ并急性心衰死亡，１例３支血管病变患者术后２个月在家中突然死亡。５例在术后３～８个月再发劳力性胸痛，其中２例再行冠脉造影示支架内再狭窄并再次支架内ＰＴＣＡ。全组随访４～２０个月，平均（１３．９±５．４）个月。结论：冠脉内支架置入是ＡＭＩ患者一个安全、有效和可行的治疗方法。
Objective: To investigate the feasibility and safety of intracoronary stenting in the treatment of acute myocardial infarction (AMI). Methods: Thirty-three patients with AMI underwent coronary stenting. Including 35 males and 8 females, aged 40 to 88 years, with an average annual (60.9 ± 10.1) years. Results: After implantation of coronary stent in 43 patients, the occluded vessels were both recanalized and the blood flow was restored to TIMI level 3. 43 patients were hospitalized for 5 to 49 days, with an average of (18.1 ± 9.1) days. One patient with AMI in the anterior wall had AMI and acute heart failure one week after operation, and one patient with 3-vessel disease died suddenly at home two months after operation. Five patients underwent recurrence of exertional chest pain 3 to 8 months after surgery. Among them, 2 patients underwent coronary angiography and again within stent restenosis. The whole group was followed up for 4 to 20 months, with an average of (13.9 ± 5.4) months. Conclusion: Coronary stenting is a safe, effective and feasible treatment for patients with AMI.
