In 52 patients with previous myocardial infraction, 49 men and 3 women (mean age 56 +/- 7.1 years) the significance of ST-segment elevation during the stress-test, was evaluated. Of the 52 patients 15 (29%) showed St-segment elevation and 37(71%), showed no alteration of the ST-segment. Extension of coronary disease, degree of obstruction, wall motion abnormalities and the presence of residual ischemia were evaluated by coronary angiography, technetium-99M pyrophosphate imaging and exercise TL-201 scintigraphy. From the results of the study one may conclude that, in patients with previous myocardial infraction exercise, ST-segment elevation is a consequence of sub-occlusion of the left anterior descending coronary artery with severe ventricular dysfunction either in patients with one or multiple vessel disease.
在52例曾有心肌梗死的患者中（49例男性，3例女性，平均年龄56±7.1岁），对负荷试验期间ST段抬高的意义进行了评估。52例患者中，15例（29%）出现ST段抬高，37例（71%）ST段无改变。通过冠状动脉造影、99m锝焦磷酸盐显像和运动铊-201闪烁扫描评估冠状动脉疾病的范围、阻塞程度、室壁运动异常和残余缺血的存在情况。从研究结果可以得出结论，在曾有心肌梗死的患者中，运动时ST段抬高是左前降支冠状动脉次全闭塞伴严重心室功能障碍的结果，无论患者是单支血管病变还是多支血管病变。
