The incidence of myocardial infarction, acute ischemic injury, and associated serum enzyme abnormalities has been evaluated in four operations involving the coronary circulation. The highest incidence of infarction was associated with internal mammary implantation (Vineberg procedure). There was no significant difference in the incidence of infarction, ischemic injury, or abnormal enzyme levels between patients with stable angina and those with unstable angina who had vein bypass surgery. In operations involving combined vein bypass grafting and valve replacement surgery, the incidence of abnormal serum enzyme elevations was higher than in any other procedure. The incidence of infarction and acute ischemic injury in combined operations was similar to that in other procedures but this may have been due to the difficulty in the ECG diagnosis of infarction in this group of patients, most of whom had abnormal preoperative ECGs.
在四项涉及冠状动脉循环的手术中，对心肌梗死、急性缺血性损伤及相关血清酶异常的发生率进行了评估。梗死发生率最高的是胸廓内动脉植入术（ Vineberg手术）。接受静脉搭桥手术的稳定型心绞痛患者和不稳定型心绞痛患者在梗死、缺血性损伤或酶水平异常的发生率上没有显著差异。在涉及静脉搭桥联合瓣膜置换手术中，血清酶异常升高的发生率高于其他任何手术。联合手术中的梗死和急性缺血性损伤发生率与其他手术相似，但这可能是由于该组患者中大多数术前心电图异常，给心电图诊断梗死带来困难所致。
