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 investigate the effect of delayed percutaneous coronary intervention on the prognosis of patients with acute myocardial infarction. Methods A total of 98 AMI patients who missed the optimal PCI duration were randomly divided into two groups: the delayed PCI group and the drug-treated group. Cardiac adverse events and echocardiographic changes during and after hospitalization were observed. Results In the PCI group, the incidence of unstable angina pectoris, heart failure, death and composite end point was significantly lower than that of the drug-treated group. Left ventricular ejection fraction increased; left ventricular end diastolic diameter was significantly reduced. Conclusion Delayed PCI can reduce the incidence of cardiovascular events in patients with AMI and improve their prognosis.
