简要总结

Obstructive sleep apnea (OSA) is a highly prevalent disorder with adverse neurocognitive and cardio-metabolic outcomes. Continuous positive airway pressure (CPAP) is the gold standard therapeutic option to treat airway obstructions during sleep and thus, prevent its adverse cardiovascular and neurocognitive outcomes. Previous clinical trials, however, have largely failed to show a consistent impact of CPAP on these health outcomes.

One of the main limitations of these trials may be the inadequate characterization of OSA and its acute physiological consequences. By characterizing OSA based on the "apnea-hypopnea index (AHI)", there is a potential risk of negative results.

In this trial, the investigators intend to tackle this issue, by better characterization of OSA-related physiological consequences during sleep using physiologically driven metrics to capture the burden of OSA-related hypoxemia ("hypoxic burden"), autonomic response ("heart rate burden"), and sleep fragmentation ("arousal burden").

结局指标

主要结局

Change from baseline 24-hour mean systolic blood pressure at 12 weeks

时间窗: 12 weeks

Mean systolic blood pressure over a 24-hour period is measured using an ambulatory blood pressure monitor.

Change from baseline Epworth Sleepiness Scale (ESS) at 12 weeks

时间窗: 12 weeks

Self-reported sleepiness measured using the Epworth Sleepiness Scale (units on a scale). Values range from 0-24; higher values indicate greater sleepiness.

Change from baseline flow-mediated vasodilation at 12 weeks

时间窗: 12 weeks

Flow mediated vasodilation is studied using high resolution ultrasound of the artery.
