Obesity in coronary heart disease: An unaddressed behavioral risk factor

[摘要] Obesity is an independent risk factor for the development and progression of coronary heart disease (CHD). Over 80% of patients with CHD are overweight or obese. While obesity is often considered a relatively minor CHD risk factor, weight loss is a broadly effective risk-factor intervention. Weight loss can profoundly influence a number of major risk factors including: hypertension, dyslipidemia and insulin resistance/type 2 diabetes mellitus. Despite its prominence as a risk factormost cardiac rehabilitation (CR) programs do not have a specific, targeted intervention to assist patients with weight loss. Consequently, the weight loss that occurs during CR is quite small and unlikely to appreciably alter risk factors. Relying on CR associated exercise as a sole intervention is an ineffective strategy to promote weight loss. There is evidence, however, that behavioral weight loss (BWL) interventions can be effectively employed in the CR setting. In contrast to programs that do not offer a targeted intervention, studies show that participants in CR-related BWL programs lose significantly more weight. The additional weight loss from the BWL intervention is associated with greater improvements in insulin sensitivity and other components of the metabolic syndrome such as hypertension and lipid abnormalities. As a means of maximizing CHD risk factor reduction CR programs need to incorporate BWL programs as a standard programming for overweight/obese patients. (C) 2017 Published by Elsevier Inc.
