Seventeen patients with positive maximal or submaximal bicycle-exercise test accompanied by painlessness and 14 patients with susceptible coronary heart disease with negative exercise test were studied and traced for 36 months. The patients underwent repeated bicycle-exercise test of the same stress and compared with those before 36 months. The results showed that 7/17 patients (41.2%) had an increase in the depressed level of ischemic type ST segment induced by exercise test. 3 of them developed effort angina pectoris: 1 suffered from myocardial infarction, 1 had recurrent atrial flutter and left heart failure, and 1 suddenly died from cardiac disease. The cardiac event rate was 3/17 (17.6%) in this group. While 14 patients with negative exercise test had no cardiac events. It seems to mean that silent myocardial ischemia detected by exercise test might have potential danger of cardiac events.
对17例最大或次最大运动试验阳性且无症状的患者以及14例运动试验阴性的易患冠心病患者进行了研究，并随访36个月。这些患者接受了相同应激水平的重复运动试验，并与36个月前的情况进行比较。结果显示，17例患者中有7例（41.2%）运动试验诱发的缺血型ST段压低程度增加。其中3例发生劳力性心绞痛，1例发生心肌梗死，1例发生复发性心房扑动和左心衰竭，1例突然死于心脏病。该组心脏事件发生率为3/17（17.6%）。而14例运动试验阴性的患者未发生心脏事件。这似乎意味着运动试验检测到的无症状心肌缺血可能存在心脏事件的潜在危险。
