A series of 89 surgical patients (111 operations) with preoperative myocardial infarction (MI) was analysed for factors predisposing to the development of a postoperative reinfarction. Six of them suffered postoperative MI, and three of these patients died. In the statistical analysis the following risk factors emerged: age over 60 years, anaemia, hypertension, and the fact that the previous MI had been posterior. Abdominal operations were more dangerous concerning reinfarction than other operations. In the other series of 11 deceased patients with postoperative reinfarction collected from the autopsy material, about the same risk factors were found. The most important factor seemed to be hypotension, which complicated the surgery. All 11 patients had arrhythmias in their preoperative electrocardiogram. Previously treated heart failure was present in five of these patients. Postoperative symptoms analysed in the first series suggest that if a patient with preoperative MI has arrhythmias, hypotension, dyspnoea, diffuse unlocalized pain or chest pain after surgery, he is very likely to have a reinfarction.
对89例有术前心肌梗死（MI）的外科手术患者（111例手术）进行了分析，以确定易导致术后再梗死的因素。其中6例发生了术后心肌梗死，3例患者死亡。在统计分析中出现了以下危险因素：年龄超过60岁、贫血、高血压以及既往心肌梗死为下壁梗死。腹部手术相对于其他手术而言，发生再梗死的危险性更高。在从尸检材料中收集的另一组11例术后再梗死死亡患者中，发现了大致相同的危险因素。最重要的因素似乎是低血压，它使手术变得复杂。所有11例患者术前心电图均有心律失常。其中5例患者既往有心力衰竭病史且接受过治疗。在第一组中分析的术后症状表明，如果术前心肌梗死患者术后出现心律失常、低血压、呼吸困难、弥漫性无定位疼痛或胸痛，那么他很可能发生再梗死。
