Continuous Nocturnal Bp Monitoring During Polysomnography: Proof of Concept Study

Abstract

Obstructive sleep apnea (OSA) is associated with cardiovascular disease, but recent randomized trials showed that current diagnostic and therapeutic algorithms for treating OSA do not lead to ideal improvements in cardiovascular outcomes. Nocturnal blood pressure (BP) is a strong predictor of adverse cardiac events, yet nocturnal BP is an under-explored modality in assessing cardiovascular impacts of OSA in part because previous BP technologies were interruptive to sleep and difficult to integrate with multi-channel PSG.
