Mortality reductions in patients receiving exercise-based cardiac rehabilitation: how much can be attributed to cardiovascular risk factor improvements?
It is unclear how much of the reduction in cardiac mortality in coronary heart disease (CHD) patients with exercise training is the result of direct effects on the heart and coronary vasculature, or to indirect effects, via primary risk factors. The aim of this article was to quantify the cardiac mortality benefits of exercise-based rehabilitation attributable to risk factor reductions versus the direct effects on the heart and vasculature.
