NCT02893865

Brief Summary

Published data indicate that obstructive sleep apnea syndrome (OSAS) worse the prognosis of coronary artery disease (CAD) and that oxidative stress can link this 2 diseases. Investigators hypothesise that oxidative stress decrease after 3 months of continuous positive airway pressure (CPAP) in this specific population. The results may have major implication in the comprehension of physiopathologic processes linking OSAS and CAD and in the treatment of OSAS in this specific population.
