CPAP for Prevention of Cardiovascular Events in Obstructive Sleep Apnea

TLDR
Therapy with CPAP plus usual care, as compared with usual care alone, did not prevent cardiovascular events in patients with moderate-to-severe obstructive sleep apnea and established cardiovascular disease.
Abstract
BackgroundObstructive sleep apnea is associated with an increased risk of cardiovascular events; whether treatment with continuous positive airway pressure (CPAP) prevents major cardiovascular events is uncertain. MethodsAfter a 1-week run-in period during which the participants used sham CPAP, we randomly assigned 2717 eligible adults between 45 and 75 years of age who had moderate-to-severe obstructive sleep apnea and coronary or cerebrovascular disease to receive CPAP treatment plus usual care (CPAP group) or usual care alone (usual-care group). The primary composite end point was death from cardiovascular causes, myocardial infarction, stroke, or hospitalization for unstable angina, heart failure, or transient ischemic attack. Secondary end points included other cardiovascular outcomes, health-related quality of life, snoring symptoms, daytime sleepiness, and mood. ResultsMost of the participants were men who had moderate-to-severe obstructive sleep apnea and minimal sleepiness. In the CPAP group, the...

Prospective study of the association between sleep-disordered breathing and hypertension.

TL;DR: A dose-response association between sleep-disordered breathing at base line and the presence of hypertension four years later was found that was independent of known confounding factors and suggest that sleep- disordered breathing is likely to be a risk factor for hypertension and consequent cardiovascular morbidity in the general population.

Long-term cardiovascular outcomes in men with obstructive sleep apnoea-hypopnoea with or without treatment with continuous positive airway pressure: an observational study

TL;DR: In men, severe obstructive sleep apnoea-hypopNoea significantly increases the risk of fatal and non-fatal cardiovascular events and CPAP treatment reduces this risk.

Sympathetic neural mechanisms in obstructive sleep apnea.

TL;DR: It is concluded that patients with obstructive sleep apnea have high sympathetic activity when awake, with further increases in blood pressure and sympathetic activity during sleep, which are attenuated by treatment with CPAP.

Adherence to continuous positive airway pressure therapy: the challenge to effective treatment.

TL;DR: Emerging data suggest that various behavioral interventions may be effective in improving CPAP adherence and patient perception of symptoms and improvement in sleepiness and daily functioning may be more important in determining patterns of use than physiologic aspects of disease severity.
