延迟PCI治疗心肌梗死患者的临床观察

Clinical observation of acute myocardial infarction patients who undertaken delayed percutaneous coronary intervention

目的探讨延迟经皮冠状动脉介入治疗对急性心肌梗死患者预后的影响。方法对98例AMI错过最佳PCI治疗时间的患者随机分为延迟PCI治疗组和药物治疗组。观察住院期间和随访期间的心血管不良事件和超声心电图变化。结果延迟PCI组较药物治疗组不稳定型心绞痛、心力衰竭、死亡和复合终点事件明显下降。左室射血分数增加;左室舒张末内径明显减小。结论延迟PCI治疗可以减少AMI患者心血管事件的发生,改善其预后。

Objective To analysis if delayed percutaneous coronary intervention （PCI） can improve clinical outcome of patients with acute myocardial infarction（AMI）. Methods 98 patients with AMI were ran- domly divideded into delayed PCI grope and medication grope. To compared major adverse cardiovascular events and the cardiac change by eehocardiography [ left ventricular ejection fraction（ LVEF）, left ventricular end-di- astolic dimension（LVEDD） ] after 6 months follow-up. Results Compared with the medication grope, delayed PCI can reduce unstable angina pectoris, heart failure, mortality, composite events, LVEDD and improve LVEF. Conclusion Delayed PCI can decrease cardiovascular composite events and improve prognosis of the patients with AMI.
