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

在这项研究中，140名冠心病患者接受了全面的 评估包括运动压力测试，24小时饮食回忆， 空腹血脂、胰岛素和葡萄糖水平以及双重X线检查 吸收测定法 在这些患者中，有97人已返回进行重复检测 经过3个月的康复训练。 主要研究假设 是：1.身体组成和/或身体脂肪分布的基线测量， 将预测冠状动脉危险因素的基线值， 甘油三酯、HDL-胆固醇、峰值有氧能力和空腹胰岛素 水平2.训练引起的身体成分和/或身体脂肪的变化 分布将预测冠状动脉危险因素测量的变化 如甘油三酯、HDL-胆固醇和空腹胰岛素水平。 我们的初步分析表明，基线体脂分布， 以腰臀比（WHR）测量， 老年人的甘油三酯水平、HDL-胆固醇和空腹胰岛素水平 患有冠状动脉疾病的女性，与其他一些女性相比， 临床上可用的措施，如大量营养素的饮食摄入。 另一方面，峰值有氧能力是低密度脂蛋白的最佳预测指标。 胆固醇 我们很快就会重新分析我们的数据， 包括性别和整个年龄范围。 此外，我们将 分析运动训练对体脂分布及相关指标的影响 冠心病危险因素

In this study, 140 coronary patients have undergone comprehensive evaluations which include exercise stress testing, 24 hour dietary recall, fasting lipid profiles, insulin and glucose levels and dual x-ray absorptiometry. Of these patients, 97 have returned for repeat testing after 3 months of exercise rehabilitation. The primary study hypotheses are:1. Baseline measures of body composition and/or body fat distribution, will predict baseline values of coronary risk factors such as serum triglycerides, HDL-cholesterol, Peak aerobic capacity and fasting insulin levels2. Training induced changes in body composition and/or body fat distribution will predict changes in measures of coronary risk factors such as triglycerides, HDL-cholesterol and fasting insulin levels. Our initial analysis showed that baseline body fat distribution, as measured by the waist to hip ratio (WHR), was the best predictor of serum triglyceride levels, HDL-cholesterol and fasting insulin levels in older women with coronary artery disease, compared with a number of other clinically available measures such as dietary intake of macronutrients. On the other hand, peak aerobic capacity was the best predictor of LDL- cholesterol. We will soon be reanalyzing our data on baseline predictors to include both genders and the entire age spectrum. In addition, we will analyze effects of exercise training on body fat distribution and related coronary risk factors.
