Obstructive sleep apnea (OSA) is associated with a number of cardiovascular comorbidities, including hypertension, heart rate (HR) alterations, cardiac arrhythmias, endothelial dysfunction and atherosclerosis.

Abstract

Obstructive sleep apnea (OSA) is associated with a number of cardiovascular comorbidities, including hypertension, heart rate (HR) alterations, cardiac arrhythmias, endothelial dysfunction and atherosclerosis. HR, in particular, is an important sign correlated with cardiac stress and survival. Previous investigations on the effects of mandibular advancement device (MAD) therapy on HR resulted in contradictory findings. The aim of the present retrospective cohort study was to evaluate the effects of MAD therapy with a fully customizable appliance on respiratory and cardiovascular parameters. Fifty adult consecutive cases with mild to severe OSA underwent split-night polysomnography (SN-PSG) at baseline (T0) and after three months of MAD treatment (T1), after appropriate titration. The apnea/hypopnea index (AHI), 4% oxygen desaturation index (ODI) and HR (average, minimum and maximum) values are recorded at T0 and at T1 and statistically compared. The AHI and ODI values improved after three months of MAD treatment. The minimum HR increased after treatment, while the maximum HR decreased after treatment. MAD treatment with a fully customizable appliance was effective in improving breathing and cardiovascular parameters in adult patients with mild to severe OSA.
