46名年龄在70岁以下的男性，无临床充血性心力衰竭或不稳定型心绞痛，在心肌梗死后3、5、7、9和11周进行了平板运动试验。患者在梗死后第7周和第11周比第3周更常能够进行中度运动（2 mph，14%运动强度;级）。缺血性ST段压低，通常不伴有心绞痛，发生在45%的患者，并与随后的冠状动脉事件的发生率显着增加。运动诱发的心室异位活动的存在提供了很少的独立预后信息。210次检查无严重并发症发生。心肌梗死后不久的运动试验提供了关于恢复体力活动能力的客观信息，包括重返工作岗位。3-5周和7-11周的两项测试似乎提供了在此期间进行的五项测试中包含的大部分信息。
Forty-six men under age 70, without clinical congestive heart failure or unstable angina pectoris, performed treadmill tests 3, 5, 7, 9 and 11 weeks after myocardial infarction. Patients were more frequently able to perform moderate exertion (2 mph, 14%percnt; grade) at 7 and 11 weeks than at 3 weeks following infarction. Ischemic ST-segment depression, usually unaccompanied by angina pectoris, occurred in 45%percnt; of patients and was associated with a significantly increased incidence of subsequent coronary events. The presence of exercise-induced ventricular ectopic activity provided little independent prognostic information. No serious complications occurred in 210 tests. Exercise testing soon after myocardial infarction provides objective information concerning the capacity to resume physical activity, including return to work. Two tests, at 3-5 weeks and at 7-11 weeks, appear to provide most of the information contained in five tests performed during this time.
