在年龄<70岁的确诊为急性心肌梗塞(AMI)的患者中:205例于平均66(2～162)个月前曾作搭桥术者,作为术后组;另选配对的205例未作搭桥术者,作为对照组。所有患者入院后24h 内记录12导联心电图3次,第2和3天各1次,7～10天内至少复查一次。血清 CK 及其 MB 在入院后24h 内按规定时间采血测定。术后组130例(63%)和对照组119例(58%)出院前冠(状动)脉和移植血管造影复查。梗塞范围的依据为:(1)CK 及其 MB 的峰值;(2)心电图 ST 段抬高程度(在 J 点后60ms 处 ST 段抬高的最多导联数和12导联上 ST 段抬高总和);(3)
Among patients diagnosed with acute myocardial infarction (AMI) <70 years of age, 205 had an average of 66 (2 to 162) months prior to being on-site as a postoperative group, and 205 matched patients For bypass surgery, as a control group. All patients recorded 12-lead electrocardiogram three times within 24 hours after admission, one each on days 2 and 3, and at least one review within 7-10 days. Serum CK and MB in blood within 24 hours after admission by blood sampling. One hundred and thirty-three patients (63%) in the postoperative group and 119 patients (58%) in the control group underwent coronary angiography and coronary angiography before discharge. The extent of the infarct was based on: (1) the peak of CK and its MB; (2) the extent of ST segment elevation in the ECG (the maximum number of ST segment elevation leads at 60 ms and the ST segment elevation at 12 leads Sum); (3)
