Patient Evaluation Criteria

Patients at risk of CVD/CHD must be rou­tinely evaluated for risk factors (Fig. 2) such as family history, smoking, hyperten­sion, hormonal status, body-fat distribution and obesity, physical activity (Fig.

3), alco­hol abuse, hypogonadism, hypothyroidism, diabetes, and renal or hepatic disease. Guidelines include the measurement of total cholesterol, HDL, LDL, and VLDL cho­lesterol, TG, lactate [39-41, 49], the measure of body compartments, body circumferences and skinfolds [28], and resting metabolic rate (RMR) as a measure of the energy expended for maintenance of physiologic functions which generally represents the largest portion of daily energy expenditure (60-75%) [31-33]. We use the WHO equa­tions for body weights and heights [34, 50] along with bioimpedance analysis (BIA) and indirect calorimetry to predict the RMRs and energy expenditure for different age and sex groups [35, 36, 51]. Energy produc­tion is estimated by measuring O2 consump­tion and CO2 production using a special calorimeter (e.g., Datex-Engstron Division Instrumentarium Corp. Helsinki, Finland; type MBM-200-23-01). RMR values normally range between 0.7 and 1.6 kcal/min accord­ing to the subject’s body composition, gen­der, and level of training.
