目的探讨直接经皮冠状动脉介入(PCI)与择期PCI后治疗急性心肌梗死的疗效。方法90例AMI患者中48例于12小时内直接行PCI,42例择期行PCI,术后1周行彩色超声心动图检查,对比左心室射血分数(LVEF),评价心功能。结果直接PCI组不稳定性心绞痛,泵功能衰竭较择期PCI组明显降低,直接PCI组LVEF优于择期PCI组,直接PCI组发生恶性心律失常高于择期PCI组。结论AMI患者PCI能更早地开通梗死相关动脉,能更好地保护心功能。
Objective To investigate the efficacy of direct percutaneous coronary intervention (PCI) and elective PCI in the treatment of acute myocardial infarction. Methods Forty-eight AMI patients underwent PCI within 12 hours and 42 patients underwent PCI. Color Echocardiography was performed one week after operation. Left ventricular ejection fraction (LVEF) was compared to evaluate cardiac function. Results The unstable angina pectoris and pump failure in the direct PCI group were significantly lower than those in the elective PCI group. The LVEF in the direct PCI group was better than that in the elective PCI group. The incidence of malignant arrhythmia in the direct PCI group was higher than that in the elective PCI group. Conclusion PCI in AMI patients can open the infarct-related artery earlier and can better protect the heart function.
