23:T4d3,Obesity is a coronary heart disease (CHD) risk factor and is prevalent in patients with CHD. The authors reviewed data in 235 consecutive patients before and after formal cardiac rehabilitation and exercise training (CRET) programs and analyzed data in 72 lean patients (body mass index [BMI] <25 kg/m(2)) vs 73 obese patients (BMI>or=30 kg/m(2)). At baseline, obese patients were significantly younger (P<.0001); had higher percentage of body fat (P<.0001) and more dyslipidemia, including higher triglycerides (TG; P<.01), lower high-density lipoprotein (HDL) cholesterol (P<.0001), and higher TG/HDL ratio (P<.0001); and had higher prevalence of metabolic syndrome (61% vs 26%; P<.01) compared with lean patients. Following CRET, obese patients had small, but statistically significant, improvements in obesity indices, including weight (P<.01), BMI (P<.01), and percentage of fat (P=.03), and had more significant improvements in peak exercise capacity (P<.001), HDL cholesterol (P<.001), C-reactive protein (P<.01), behavioral characteristics, and quality of life (P<.0001). The prevalence of metabolic syndrome fell (62% to 51%; P=.1). These results support the benefits of CRET to reduce overall risk in obese patients with CHD.24:T400,Obstructive sleep apnea (OSA) and the metabolic syndrome (MS) are independently associated with increased cardiovascular risk. The objective of the present study was to determine the prevalence of OSA among consecutive patients with MS and to determine whether OSA is associated with impaired glycemic control. Fifty consecutive patients with a recent diagnosis of MS and no previous diagnosis of OSA underwent a polysomnography and anthropometric and laboratory measurements. The prevalence of OSA (apnea-hypopnea index >or=15 events per hour of sleep) was 68% and in the same range of all other individual components of MS. Moreover, OSA was associated with increased levels of glucose (P=.03) and glycosylated hemoglobin (P=.03) but not with body mass index (P=.30). Glycosylated hemoglobin was independently associated with glucose (P<.001) and apnea-hypopnea index (P=.03). The prevalence of OSA is in the same range as all the individual components of MS and is independently associated with impaired glycemic control.25:T44f,Thirty-four children were assessed for body composition, blood pressure, lipids, glucose tolerance, markers of insulin resistance, oxidative stress, and adipokines. Children were divided into 3 groups: (1) normal weight, (2) overweight but otherwise healthy, and (3) overweight with the metabolic syndrome. There were no differences among any of the groups for age or Tanner stage, and anthropometric variables were similar between the overweight and the overweight with the metabolic syndrome groups. Differences across groups were found for high-density lipoprotein cholesterol (P < .001), triglycerides (P < .01), fasting insulin (P < .001), homeostasis model assessment (P < .01), adiponectin (P < .05), leptin (P < .0001), C-reactive protein (P < .0001), interleukin 6 (P < .0001), and 8-isoprostane (P < .001). In children, oxidative stress and adipokine levels worsen throughout the continuum of obesity and especially in the presence of components of the metabolic syndrome. Overweight children with components of the metabolic syndrome may be at elevated risk for future cardiovascular disease.26:T41d,Total body fat and adipose tissue distribution are associated with cardiometabolic risk, yet there are conflicting data as to whether waist circumference (WC) or body mass index (BMI) is a better predictor of cardiovascular risk. To determine whether WC or BMI was more strongly associated with cardiometabolic risk, family members of patients with cardiac disease were studied (N=501; mean age, 48 years; 66% female; 36% nonwhite). Height, weight, WC, BMI, blood pressure, high-density lipoprotein cholesterol, triglycerides, glucose, high-sensitivity C-reactive protein, and lipoprotein-associated phospholipase A(2) were systematically measured. Global risk was calculated using the Framingham funct
