The dependant variable is conceptually defined as "Modest reductions in BMI, obesity, and severe obesity occur after cardiac rehabilitation. In addition, obese patients demonstrate significant improvements in most coronary risk factors. This variable is studied in references 8-14, and is relevant to the data needed for the research study. There is limited data available on the effects of vigorous risk factor intervention in obese patients with known CHD. The article also states that the effects of cardiac rehabilitation and exercise training in obese patients with CHD have not been well studied.
