Sleep-disordered breathing and cardiovascular health

PURPOSE OF REVIEW: Sleep-disordered breathing is a widely prevalent condition and may have serious medical, social, and economic consequences. This review evaluates the role of sleep-disordered breathing in cardiovascular morbidity and mortality on the basis of recent literature. RECENT FINDINGS: Epidemiologic studies, retrospective reviews, and prospective clinical trials suggest a strong association between sleep-disordered breathing and adverse cardiovascular events. Individuals with sleep-disordered breathing have a higher prevalence of hypertension, which attenuates with treatment. Furthermore, the presence of sleep-disordered breathing augurs an increased risk of coronary artery disease, cardiac arrhythmias, and heart failure. SUMMARY: Recent research provides an emerging evidence of the role of sleep-disordered breathing as a risk factor for diverse cardiovascular disorders.
