Effects of Exercise Training on Endothelial Function, Inflammation, Arterial Stiffness and Autonomic Function in Coronary Artery Disease Patients
In Brief
A clinical study evaluating Exercise-based cardiac rehabilitation program for Coronary Artery Disease. Completed, enrolled 96 participants across 1 site.
Detailed 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.

Timeline
Interventions
The intervention consists of usual medical care (i.e., medicine prescription and counseling of lifestyle modifications) and an supervised outpatient aerobic exercise training, which will be performed 3 days per week for 8 weeks. Each exercise session include 10 min of warm up, 35 min of aerobic exercise (i.e., cycloergometer or treadmill) and 10 min of cool down. The exercise intensity will be calculated as 65- 75% of maximal heart rate achieved in the treadmill exercise testing. Individualized exercise prescription will be periodically adjusted. A perceived exertion scale will be used as an adjunctive intensity modulator. In addition, each patient will be encouraged to daily exercise outside the formal exercise program.
