WASHINGTON – The treatment of mild obstructive sleep apnea with CPAP devices or mandibular advancement devices does not improve blood pressure or endothelial function after one year, even in patients with effective treatments, according to a study published in the Journal of Clinical Sleep Medicine. The study’s objectives were to evaluate and compare the effects of CPAP, MAD and no treatment on 24-hour ambulatory blood pressure monitoring and peripheral arterial tonometry at six and 12-month follow-ups in individuals with mild OSA and in a subgroup who had an apnea-hypopnea index of less than five events/h and adherence of greater than or equal to four hours per night (effective-treatment subgroup). Users of both devices had lower apnea-hypopnea indexes than a control group, but users of CPAP devices had higher blood oxygen levels than users of MADs, according to the study. Users of MADs had more hours of treatment per night and better adaptation to treatment than users of CPAPs, the study found.
