Mechanisms of Endothelial Cell Dysfunction in Sleep Apnea
In Brief
A clinical study evaluating Continuous Positive Airway Pressure (CPAP) for Obstructive Sleep Apnea and Hypoxemia. Completed, enrolled 70 participants across 1 site.
Detailed Summary
Sleep apnea is a common sleep disorder characterized by temporary stops in breathing during sleep and has been associated with the development of cardiovascular disease. This research will investigate one potential mechanism leading to the development of cardiovascular disorder, specifically, the blockage of blood vessels called "vascular occlusion", in subjects with sleep apnea. A group of healthy controls will be used for comparison. All subjects will undergo clinical evaluation followed by an overnight sleep study and a morning blood draw. Subjects with sleep apnea will be treated according to standard clinical management and followed under the research protocol for one month. At the end of one month, a repeat blood draw will be performed on the sleep apnea subjects for comparative analysis. If a control subject is found to have any abnormality during this research study, he or she will be referred for further clinical evaluation.

Timeline
Interventions
Continuous positive airway pressure (CPAP) is a method of respiratory ventilation which is accepted as the gold standard to treat Obstructive Sleep Apnea (OSA). Subjects found to have OSA after the Nocturnal Polysomnography (NPSG) will be trained in the use of CPAP and will be instructed to use CPAP every night for 30 nights. These subjects will then return for a post-treatment blood draw.
