Largest Sleep Apnea Trial Backs CPAP For Improving QoL, Not For Lowering Secondary Cardio Events

Executive Summary

In the largest sleep apnea study ever conducted, continuous positive airway pressure (CPAP) did not appear to lower the risk of cardiovascular adverse events including cardiovascular death, myocardial infarction, stroke, or hospitalization for unstable angina in patients with obstructive sleep apnea and known cardiovascular disease. However, patients in the trial only used CPAP a few hours a night, on average, indicating that an easier-to-use version of CPAP might yield better outcomes.
