Clinical Trial Summary

Although coronary heart disease (CHD) treatment guidelines recognize obesity as a major modifiable risk factor,2 nearly half of all CHD patients are obese and the current standard of care fails to implement evidence-based obesity treatment for this high-risk population. Multiple lines of evidence suggest that weight loss improves outcomes in CHD patients. The primary goal of this study is to determine the feasibility of adding a 6-month behavioral weight loss intervention to exercise-based cardiac rehabilitation.


Clinical Trial Description

Although coronary heart disease (CHD) treatment guidelines recognize obesity as a major modifiable risk factor,2 nearly half of all CHD patients are obese and the current standard of care fails to implement evidence-based obesity treatment for this high-risk population. The efficacy of exercise-based cardiac rehabilitation for improving exercise capacity and CHD risk factors is markedly blunted in CHD patients with obesity. Current programs largely focus on nutrient intake and produce minimal weight loss, on average. Our data show that despite appropriate exercise prescription and adherence, only 22% of CHD patients with obesity lose even the minimum recommended body weight over a 3-month program. These findings indicate that targeting reductions in caloric intake is needed to optimize outcomes in these patients and suggest that current programs are too short to produce adequate weight loss and ensure the necessary behavioral adaptations for long-term maintenance. Randomization to diet-induced weight loss in combination with aerobic exercise improves exercise capacity, quality of life, and CHD risk factors more than exercise alone and reduces long-term mortality in overweight and obese adults. The primary goal of this study is to determine the feasibility of adding a 6-month behavioral weight loss intervention to exercise-based cardiac rehabilitation. ;
