Out of 636 patients with acute myocardial infarction (AMI) admitted to our institution, 183 patients enrolled in our non-supervised home exercise program immediately after their discharge from the hospital. The first 40 patients were randomized to control and training group, while the remaining 143 patients were included in the training group. Before and after the trial, all patients underwent cardiopulmonary exercise testing; submaximal graded treadmill exercise test with the application of expiratory gas analysis. In the training group, patients performed 2 km walk-jog exercise everyday for 1 month, keeping their heart rate (HR) at 90-100% of that in the anaerobic threshold. HR during exercise was monitored by patients themselves, using HR-meter. The anaerobic threshold significantly increased in the training group; while control group had no significant changes. VO2 and HR significantly increased at the same Borg's indices. Psychological improvement was also obtained in the training group compared to control group. It is concluded that non-supervised home exercise program is effective and easily applicable in the convalescent phase of AMI.
在我院收治的636例急性心肌梗死（AMI）患者中，183例在出院后立即参加了我们的非监督式家庭锻炼计划。前40例患者被随机分为对照组和训练组，其余143例患者被纳入训练组。试验前后，所有患者均接受了心肺运动测试；采用呼气气体分析进行次极量递增平板运动试验。在训练组中，患者每天进行2公里的步行-慢跑运动，持续1个月，将心率（HR）保持在无氧阈心率的90-100%。运动期间的心率由患者本人使用心率计进行监测。训练组的无氧阈显著增加；而对照组无显著变化。在相同的伯格指数下，VO2和HR显著增加。与对照组相比，训练组的心理状况也有所改善。结论是非监督式家庭锻炼计划在AMI恢复期有效且易于实施。
