１６例急性心肌梗（ＡＭＩ）患者发病后恢复期（２～４周）行及冠状动脉内支架术治疗。分为两组，梗塞后心绞痛组６例，梗塞后心功能不全组１０例。经冠脉造影证实其梗塞相关冠状动脉均处于完全闭塞及次全闭塞状态。１５例为单支，１例为双支。术前平均狭窄度（９２．５±５．１）％，平均狭窄长度（１９．５±５．３）ｍｍ。共植入１９枚支架。手术成功率１００％，１例术后３天发生亚急性血栓形成。术后造影显示平均狭窄度为０～１０％，梗塞后心绞痛组临床症状消失，梗塞后心功能不全组的超声心动图提示左房内径（３６．８±３．４）ｍｍ，左室内径（５５．１０±３．７３）ｍｍ，左室射血分数０．６１±０．０８，优于术前的左房内径（３９．４０±４．１２）ｍｍ，左室内径（５９．６０±５．２５）ｍｍ，左室射血分数０．５２±０．１０。随访１～２０个月无１例死亡，无再梗塞，心功能均在Ⅰ～Ⅱ级。本文说明ＡＭＩ恢复期冠脉再通是增加冠脉血流，维持正常心功能和降低死亡率的一个有效方法。
16 patients with acute myocardial infarction (AMI) recovery after onset (2 to 4 weeks) and coronary stenting. Divided into two groups, 6 cases of post-infarction angina group, 10 cases of post-infarction heart failure group. Coronary angiography confirmed its infarct-related coronary arteries were in complete occlusion and subtotal occlusion. Fifteen were single and one was double. The average preoperative stenosis (92.5 ± 5.1%), the average length of stenosis (19.5 ± 5.3) mm. A total of 19 stents were implanted. Surgical success rate was 100%, 1 case of subacute thrombosis occurred 3 days after surgery. Postoperative angiography showed that the average stenosis ranged from 0 to 10%. The clinical symptoms disappeared in the post-infarction angina group. The echocardiogram of the left ventricular dysfunction group after infarction showed that the left atrium diameter (36.8 ± 3.4) mm, the left ventricular internal diameter 55.10 ± 3.73) mm, left ventricular ejection fraction 0.61 ± 0.08, better than preoperative left atrium diameter (39.40 ± 4.12) mm, left ventricular internal diameter (59.60 ± 5.25) mm, left ventricular ejection fraction 0.52 ± 0.10. No follow-up of 1 to 20 months of death, no further infarction, heart function are in Ⅰ ~ Ⅱ grade. This article shows that AMI convalescent coronary recanalization is an effective way to increase coronary blood flow, maintain normal cardiac function and reduce mortality.
