NCT02623088

Brief Summary

Obstructive sleep apnea syndrome is responsible of endothelial dysfunction, which is a independent cardio-vascular risk factor. Assessment of pulse wave velocity (PWV) and peripheral arterial tone (PAT) are study measurements of arterial stiffness, and are strong predictors of late cardiovascular events. This study will compare long term evolution in arterial stiffness (PWV) and endothelial dysfunction (PAT) for patients treated by Positive Airway Pressure Therapies.
