Vascular Endothelial Dysfunction in Sleep Apnea

Purpose

This double-blind placebo-controlled parallel group randomized study design will be used to test whether 4 weeks of atorvastatin 10 mg daily reduces levels of inflammatory markers in OSA patients treated with CPAP (standard of care). The purpose of this study is to investigate: 1) whether statins reduce endothelial inflammation and pro-thrombotic conditions in OSA, including in patients adherent to CPAP (Aim 1); and 2) whether statins reduce endothelial inflammation and pro-thrombotic conditions by improving endothelial cholesterol metabolism and trafficking in OSA (Aim 2).

Arm Groups

ArmDescriptionAssigned Intervention
Active Comparator
Treatment
OSA patients who adhered or did not adhere with CPAP who are randomized to receive atorvastatin 10 mg daily.
  • Drug: Atorvastatin 10mg
    Atorvastatin 10 mg daily for 28 days will be randomly allocated to OSA patients regardless of adherence with CPAP. Atorvastatin and placebo will be encapsulated to appear identical and dispensed by the research pharmacy.
    Other names:
    • statin
  • Other: Continuous Positive Airway Pressure Therapy
    CPAP is a standard of care for OSA and will be prescribed by care providers not associated with this study based on clinical indications. The investigators will have no role in prescribing CPAP.
    Other names:
    • CPAP
Placebo Comparator
Control
OSA patients who adhered or did not adhere with CPAP who are randomized to receive placebo daily.
  • Drug: Placebo
    Placebo daily for 28 days will be randomly allocated to OSA patients regardless of adherence with CPAP. Atorvastatin and placebo will be encapsulated to appear identical and dispensed by the research pharmacy.
  • Other: Continuous Positive Airway Pressure Therapy
    CPAP is a standard of care for OSA and will be prescribed by care providers not associated with this study based on clinical indications. The investigators will have no role in prescribing CPAP.
    Other names:
    • CPAP

Detailed Description

Obstructive sleep apnea (OSA), a condition that affects a quarter of American adults, triples the risk for cardiovascular diseases and increases all-cause mortality. Standard therapy with continuous positive airway pressure (CPAP) does not improve cardiovascular risk. Based on the investigators' mechanistic observation that the abnormal cycle of endothelial inflammation can be disrupted with statin therapy, the investigators now propose randomized clinical trial of statins vs. placebo to determine its effects on endothelial dysfunction in OSA patients treated with CPAP, which may provide the basis for practical clinical trials of statins for reducing cardiovascular risk in OSA.
