目的:探讨急性心肌梗死(AMI)后冠状动脉自发再灌注(SR)的影响因素及其临床意义。方法:115例首次发作AMI且未经静脉溶栓及其他再灌注治疗的患者,根据选择性冠状动脉造影(CAG)检查结果分成SR组(TIMI≥2级)与无SR组(TIM1 0~1级),分析影响SR的相关因素,并分组比较SR对左室功能和临床转归的影响。结果:①AMI后冠状动脉SR率为42.6%。②SR组患者心功能优于无SR组。③住院期间心脏事件发生率SR组低于无SR组(P<0.05)。④梗死前心绞痛、起病至开始治疗时间和梗死相关动脉部位与SR有关(P<0.05)。结论:未经静脉溶栓及其他再灌注治疗的AMI患者有一定的SR率(42.6%),梗死前心绞痛、起病至开始治疗时间和梗死相关动脉部位是SR的独立影响因素;SR是判断AMI预后良好的预测指标。
Objective: To investigate the influential factors and clinical significance of spontaneous reperfusion (SR) in coronary artery after acute myocardial infarction (AMI). Methods: One hundred and fifteen patients with initial AMI who were not treated with intravenous thrombolysis and other reperfusion were divided into SR group (TIMI≥2 grade) and no SR group (TIM1 0 ~ 1) according to the results of selective coronary angiography (CAG) Grade), analyze the relevant factors affecting the SR, and subgroups compared the effect of SR on left ventricular function and clinical outcome. Results: ① The SR rate of coronary artery after AMI was 42.6%. ②SR patients with heart function better than without SR group. ③ The incidence of cardiac events during hospitalization in SR group was lower than that in SR group (P <0.05). ④ pre-infarction angina, onset and treatment time and infarct-related artery sites and SR (P <0.05). CONCLUSIONS: There was a certain SR rate (42.6%) in patients with AMI without intravenous thrombolysis and other reperfusion. The incidence of pre-infarction angina pectoris, onset to treatment time, and infarct-related artery sites were independent risk factors for SR. AMI prognosis good predictors.
