An increased accumulation of fat in the intra-abdominal cavity is highly correlated with adverse coronary risk profiles. Cardiac rehabilitation (CR) produces a host of health benefits related to modifiable cardiovascular risk factors. Further research is needed to define better program for weight loss and risk improvement in coronary patients. The aim of this study was to determine the effect of supervised and unsupervised cardiac rehabilitation program on body composition and body fat distribution in a population with coronary artery disease.
The study investigated 167 patients with coronary artery disease (73% males; mean age = 52.67±9.11 years) before and after a supervised protocol cardiac rehabilitation program, and 12-months later. Target variables included body fat distribution indices (waist and hip circumference and waist to hip ratio), weight and body mass index.
Weight, waist circumference, waist to hip ratio and body mass index significantly decreased with 2 month supervised program (P<0.001), but hip circumference was not significantly changed. Males improved to a greater extent than the female patients. All of measurements relatively returned to baseline at the end of program (after 12 months).
Supervised cardiac rehabilitation program results in improvements in body composition and body fat distribution. The effects of non-supervised program were minimal and the program needed to be reviewed.
腹腔内脂肪堆积增加与不良的冠状动脉风险状况高度相关。心脏康复（CR）能带来一系列与可改变的心血管风险因素相关的健康益处。需要进一步研究来为冠心病患者制定更好的减肥和风险改善方案。本研究的目的是确定有监督和无监督的心脏康复方案对冠心病患者身体成分和体脂分布的影响。
该研究在有监督的心脏康复方案实施前后及12个月后对167例冠心病患者（73%为男性；平均年龄=52.67±9.11岁）进行了调查。目标变量包括体脂分布指数（腰围和臀围以及腰臀比）、体重和体重指数。
经过2个月的有监督方案，体重、腰围、腰臀比和体重指数显著下降（P<0.001），但臀围没有显著变化。男性的改善程度大于女性患者。在方案结束时（12个月后），所有测量值相对恢复到基线水平。
有监督的心脏康复方案可改善身体成分和体脂分布。无监督方案效果甚微，该方案需要重新评估。
