Overview
Brief Summary
The main purposes of this study is to analyze, in a randomized controlled trial, the effects of an exercise-based cardiac rehabilitation program (i) on biomarkers of endothelial function, (ii) on biomarkers of inflammation, (iii) on autonomic function, and (iv) on arterial stiffness in coronary artery disease patients (CAD). Additionally, the investigators aim to analyze the (v) contribution of age and the changes in traditional risk factors to the modification of the endothelial dysfunction and inflammation, and (vi) the contribution of the changes in inflammatory and endothelial function biomarkers to the modification of autonomic function and arterial stiffness.
The investigators hypothesize that exercise training will improve the autonomic function, arterial stiffness and mitigate the endothelial dysfunction and inflammation in CAD patients even in the absence of significant changes in traditional risk factors. Thus, the investigators expect with the present study to promote, develop and expand the knowledge in this field by assessing the impact of exercise on a pool of markers that provide a wide picture of the pathophysiological processes underlying CAD.
