One hundred fifty-six myocardial infarction patients were randomly assigned to either exercise plus relaxation and breathing therapy (treatment A, n = 76) or to exercise training only (treatment B, n = 80). Effects on exercise testing showed a more pronounced training bradycardia and a remarkable improvement in ST abnormalities in treatment A (p less than 0.005). A model was developed to integrate the various exercise parameters into a single measure for training benefit. Approximately half the patients showed a training success, with a more positive and less negative outcome in treatment A (p = 0.09). The odds for failure were 0.25 for treatment A and 0.51 for treatment B (odds ratio: 2.04; 95% confidence interval, 0.94 to 4.6). Thus the risk of failure was reduced by half when relaxation was added to exercise training. These results indicate that exercise training is not successful in all MI patients and that relaxation therapy enhances training benefit.
156名心肌梗死患者被随机分为两组，一组接受运动加放松及呼吸疗法（治疗A组，n = 76），另一组仅接受运动训练（治疗B组，n = 80）。运动测试结果显示，治疗A组训练性心动过缓更为明显，ST段异常有显著改善（p < 0.005）。建立了一个模型，将各种运动参数整合为一个衡量训练效益的单一指标。约一半患者显示训练成功，治疗A组的结果更积极，消极结果更少（p = 0.09）。治疗A组失败的几率为0.25，治疗B组为0.51（优势比：2.04；95%置信区间，0.94至4.6）。因此，在运动训练中加入放松疗法可使失败风险降低一半。这些结果表明，运动训练并非对所有心肌梗死患者都有效，放松疗法可提高训练效益。
