We investigated the changes of an 8-week cardiac rehabilitation (CR) program on physiological outcomes and health-related quality of life (HRQL) in Japanese cardiac surgery patients. Subjects were 47 consecutive outpatients (32 men, 15 women; mean age 59.4 ± 12.6 years) recovering from cardiac surgery. Patients performed both aerobic exercise on a treadmill at anaerobic threshold intensity and moderate resistance training 2 days per week, 60 min per session, from 1 to 3 months after cardiac surgery. Differences in the eight SF-36 subscale scores and physiological outcomes within the patient group at 1 month and at 3 months after cardiac surgery were analyzed. Peak oxygen uptake, handgrip strength, and knee extension strength were used as physiological outcome measures. HRQL was assessed with the Japanese version Medical Outcome Study Short Form 36 (SF-36). Significant change in overall physiological outcome from 1 month to 3 months was observed. There was also significant change in seven of the eight SF-36 health status subscale scores (physical functioning, role-physical, bodily pain, general health, vitality, role-emotional, and mental health). However, with the exception of physical functioning and mental health scores, values did not reach those of the average healthy Japanese. In conclusion, we found that CR exercise training for Japanese cardiac surgery patients during the recovery phase changes not only physiological outcomes but also HRQL as assessed by the SF-36.
我们调查了一项为期8周的心脏康复（CR）计划对日本心脏手术患者生理指标和健康相关生活质量（HRQL）的影响。研究对象为47例连续的心脏手术后门诊患者（男性32例，女性15例；平均年龄59.4±12.6岁）。患者在心脏手术后1至3个月，每周进行2天有氧运动，在跑步机上以无氧阈值强度进行，每次60分钟，同时进行中度抗阻训练。分析了患者组在心脏手术后1个月和3个月时八个SF-36子量表得分和生理指标的差异。峰值摄氧量、握力和膝关节伸展力量用作生理指标。HRQL采用日本版医学结局研究简明健康调查量表（SF-36）进行评估。观察到从1个月到3个月总体生理指标有显著变化。八个SF-36健康状况子量表得分中的七个（身体功能、身体角色、身体疼痛、总体健康、活力、情感角色和心理健康）也有显著变化。然而，除了身体功能和心理健康得分外，其他数值未达到日本健康人群的平均水平。总之，我们发现日本心脏手术患者在康复阶段进行CR运动训练不仅会改变生理指标，还会改变通过SF-36评估的HRQL。
