Outcome Measures

Primary Outcomes (1)

  • To compare the effects of nocturnal supplemental oxygen and PAP versus optimized medical management on biomarkers of cardiovascular risk, including:

    * 24 hour blood pressure (BP) profile * Markers of systemic inflammation * Markers of oxidative stress * Prothrombotic markers * Sympathetic nervous system activity * Cardiac rhythm, impulse generation and ischemia * Dyslipidemia * Glucose regulation * Myocardial stress

    3 months

Secondary Outcomes (2)

  • Compare the effects of nocturnal supplemental oxygen and PAP versus standard care on patient-reported outcomes, including:

    3 months

  • Compare nocturnal supplemental oxygen and PAP on measures of:

    3 months

Interventions

Participants randomized to this arm will be educated on PAP and then use PAP for 3 months. They will also receive optimized medical preventive therapy according to current American Heart Association guidelines for prevention of CVD and sleep guidelines.
