To assess the benefits of regular participation in a medically supervised cardiac rehabilitation program, 22 patients who had undergone coronary artery bypass (2 groups of 11 each) were studied retrospectively. Group I (mean age 53 years) was currently enrolled in the rehabilitation program. Group II (mean age 56 years) had begun but had discontinued the program. The stated reasons for discontinuation were not medical. There was no difference in entry exercise tests, and presurgical catheterization data in both groups were comparable. Mean peak oxygen consumption (VO2) by modified Douglas bag technique, heart rate X systolic blood pressure product, and treadmill duration time were recorded in a single testing period. Results revealed that Group I had higher peak VO2 (30 ml/kg/min) than Group II (24) (p less than 0.005) and greater treadmill time (11 minutes) than Group II (8) (p less than 0.01). Nine of 11 subjects in Group I were fully employed, versus 4 of 11 in Group II (p less than 0.01). One of 11 subjects in Group I had been rehospitalized versus 5 in Group II. None in Group I but 4 of 11 subjects in Group II smoked. Thus, based on the sampling and methodology of this study, it is concluded that coronary artery bypass patients in rehabilitation programs have greater peak VO2 and treadmill test time, smoke less, are less often rehospitalized, and are more often fully employed than those who are not in such programs.
为评估定期参加医学监督下的心脏康复计划的益处，对22例接受冠状动脉搭桥手术的患者（分为两组，每组11例）进行了回顾性研究。第一组（平均年龄53岁）目前正在参加康复计划。第二组（平均年龄56岁）已开始但中断了该计划。中断的既定原因并非医疗方面的。两组的入院运动测试无差异，术前导管插入术数据具有可比性。在单个测试期间记录了通过改良道格拉斯袋技术测得的平均峰值耗氧量（VO2）、心率×收缩压乘积以及跑步机运动时间。结果显示，第一组的峰值VO2（30毫升/千克/分钟）高于第二组（24）（p<0.005），跑步机运动时间（11分钟）长于第二组（8分钟）（p<0.01）。第一组11名受试者中有9名全职工作，而第二组11名受试者中只有4名（p<0.01）。第一组11名受试者中有1名再次住院，而第二组有5名。第一组无人吸烟，而第二组11名受试者中有4名吸烟。因此，基于本研究的抽样和方法，得出结论：参加康复计划的冠状动脉搭桥患者比未参加此类计划的患者具有更高的峰值VO2和跑步机测试时间，吸烟更少，再次住院的频率更低，全职工作的频率更高。
