The predictive value of angina pectoris and T wave changes was studied prospectively in 177 consecutive cases with acute myocardial infarction. A total of 21 reinfarctions developed within three months. In 11 of them (52%) at least one electrocardiogram recorded while in hospital showed a steeply ascending limb of the negative T wave, compared with 20 (13%) of those who did not reinfarct. Twenty-one patients had recurrent angina pectoris at rest during the hospital stay, and 10 of them (48%) developed a reinfarction within three months. When combining the electrocardiographic criteria and recurrent angina at rest, 14 of the 21 (67%) reinfarctions were correctly predicted, and 30 of the 156 (19%) patients not developing a reinfarction were falsely predicted.
对177例连续的急性心肌梗死患者进行前瞻性研究，以探讨心绞痛和T波改变的预测价值。在三个月内共发生21次再梗死。其中11例（52%）在住院期间至少有一次心电图记录显示负向T波的上升支陡峭，而未发生再梗死的患者中有20例（13%）出现这种情况。21例患者在住院期间有静息性复发性心绞痛，其中10例（48%）在三个月内发生再梗死。当结合心电图标准和静息性复发性心绞痛时，21例再梗死中有14例（67%）被正确预测，而156例未发生再梗死的患者中有30例（19%）被错误预测。
