对69例发病≤12h急性心肌梗塞患者，行静脉溶栓或经皮冠状动脉腔内成形术，使梗塞相关冠状动脉（IRA）再通。以胸痛缓解≥75％、90min抬高ST总和回落≥1/3、90min时CPK升高≥2倍及CPK峰值距发病≤16h为判断IRA再通临床指标，发现以上无创性指标判断IRA再通的敏感性为63％～76％，特异性为69％～80％，阳性预测值为75％～83％。同时，以上无创性指标判断发病≤6h者IRA再通准确性较发病＞6h者高。
69 cases of patients with acute myocardial infarction ≤12h, intravenous thrombolysis or percutaneous transluminal coronary angioplasty, the infarct-related coronary artery (IRA) recanalization. To chest pain relief ≥75%, 90min elevation ST total decline ≥1 / 3,90min CPK increase ≥2times and CPK peak incidence ≤16h To judge the reperfusion of IRA clinical indicators and found that the above noninvasive indicators to determine IRA recanalization The sensitivity was 63% to 76%, the specificity was 69% to 80%, and the positive predictive value was 75% to 83%. At the same time, the above non-invasive indicators to determine the incidence of ≤ 6h IRA recanalization accuracy than the incidence of> 6h high.
