One hundred and twenty asymptomatic patients underwent a submaximal treadmill exercise 2-3 weeks after an acute myocardial infarction. These patients were subsequently followed from 15 to 54 months (average 2 years). Coronary events (cardiac death or angina) occurred in 14% of the patients with normal response, in 55% of those with ischemic response and in 12% of those with abnormal but non-ischemic response. The incidence of coronary events in patients with ischemic response is significantly higher than in the other two groups. However, among the patients who had a normal response, one out of seven suffered from a coronary event during the follow-up period. More than 25% of our patients with an ischemic response to the early exercise testing showed a non-ischemic response during a second one. On the other hand, more than 25% of our patients with normal early exercise test had an ischemic response when the test was performed at the end the follow-up period. Submaximal exercise testing of asymptomatic patients early after an acute myocardial infarction does not seem to be predictive of future coronary events and its long-term reproducibility is poor.
120例无症状患者在急性心肌梗死后2 - 3周进行了次极量平板运动试验。这些患者随后被随访15至54个月（平均2年）。正常反应的患者中14%发生了冠状动脉事件（心源性死亡或心绞痛），缺血反应的患者中55%发生了冠状动脉事件，异常但非缺血反应的患者中12%发生了冠状动脉事件。缺血反应患者的冠状动脉事件发生率显著高于其他两组。然而，在反应正常的患者中，七分之一在随访期间发生了冠状动脉事件。早期运动试验有缺血反应的患者中，超过25%在第二次试验时显示为非缺血反应。另一方面，早期运动试验正常的患者中，超过25%在随访期末进行试验时出现了缺血反应。急性心肌梗死后早期对无症状患者进行次极量运动试验似乎不能预测未来的冠状动脉事件，且其长期重复性较差。
