BODY COMP/CORONARY RISK FACTOR INTERACTIONS IN REHAB OF OLDER CORONARY PTS.

这项研究的目的是区分运动训练、身体成分的变化和饮食摄入量的变化对冠心病人群中冠状动脉危险因素的影响。研究人群包括122名最近遭受冠状动脉事件的患者，他们正在进入门诊心脏康复计划。数据收集包括健康测量，如峰值有氧能力，身体成分，身体脂肪分布，以及冠状动脉危险因素的测量，如血脂谱，血糖和胰岛素测量。在调理之前，研究发现，测量体脂分布是预测老年女性冠心病危险因素的最佳指标。在男性冠心病患者中，这种情况略有不同，因为与女性相比，肥胖的一般指标，如体重、体重指数和脂肪质量，最能预测冠状动脉危险因素。在3个月的心脏康复运动训练中，男性比女性更大程度地减少了脂肪质量和腰围。男性和女性的高密度脂蛋白水平都有所增加，而其他脂肪亚组分、葡萄糖和胰岛素水平没有变化。某些脂质亚组分测量最不正常的患者，如甘油三酯值超过250 mg/dL的患者，在调节后这一指标显著下降25%。调节后危险因素的变化与身体成分或体脂分布的变化并不密切相关。

The goal of this study is to discriminate the effect of exercise training, changes in body composition and changes in dietary intake on coronary risk factors in a coronary population. The study population consisted of 122 patients who had recently suffered a coronary event who were entering the outpatient cardiac rehabilitation program. Data collection included measures of fitness such as peak aerobic capacity, body composition, body fat distribution and measures of coronary risk factors such as lipid profiles, glucose and insulin measures. Before conditioning, it was found that measures of body fat distribution were the best predictors of coronary risk factors in older women with coronary heart disease. In male coronary patients this situation is somewhat different as it was found that in contrast to women, general measures of obesity such as body weight, body mass index and fat mass best predicted coronary risk factors. In response to 3 months of cardiac rehabilitation exercise conditioning males decreased fat mass and waist circumference to a greater degree than women. Both men and women increased their HDL levels whereas other lipid subfractions, glucose and insulin levels were unchanged. Patients with the most abnormal measures of certain lipid subfractions, such as patients with triglyceride values over 250 mg/dL, experienced a significant 25% decrease in this measure after conditioning. Changes in risk factors after conditioning were not closely associated with changes in body composition or body fat distribution.
