Primary Outcome Measures:
  • To compare the effects of nocturnal supplemental oxygen and PAP versus optimized medical management on biomarkers of cardiovascular risk, including: [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    • 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


Secondary Outcome Measures:
  • Compare the effects of nocturnal supplemental oxygen and PAP versus standard care on patient-reported outcomes, including: [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    • vitality
    • self reported sleepiness

  • Compare nocturnal supplemental oxygen and PAP on measures of: [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    • efficacy (AHI, hypoxemia)
    • adherence
    • side effects

Arms Assigned Interventions
HLSE plus PAP Other: Healthy Lifestyles and Sleep Education plus PAP
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.
HLSE plus Oxygen Other: Healthy Lifestyles and Sleep Education plus Supplemental Oxygen
Participants randomized to this arm will be educated on nocturnal supplemental oxygen and then use oxygen for 3 months. They also will receive optimized medical preventive therapy according to current American Heart Association guidelines for prevention of CVD and sleep guidelines.
Healthy Lifestyles and Sleep Education Other: Healthy Lifestyles and Sleep Education
Participants randomized to this arm will receive optimized medical preventive therapy according to current American Heart Association guidelines for prevention of CVD and sleep guidelines.

Detailed Description:

This is a Phase II randomized controlled trial that will evaluate the effects of supplemental nocturnal oxygen or Positive Airway Pressure (PAP) therapy, compared to optimal medical preventive therapy for Cardiovascular Disease (CVD) risk, on biomarkers of CVD risk in Obstructive Sleep Apnea (OSA) patients at high risk for CVD events. The study will focus on patients with moderate to severe OSA but only mild OSA symptoms.

Eligible participants have a history or symptoms of heart disease AND have symptoms of sleep apnea or snoring. Participants will be contributing to medical knowledge about different options that can be used to improve heart disease in people with sleep apnea.
