Abstract

Rationale: The directionality of the relationship between sleepdisordered breathing and heart failure is controversial. Objectives: We assessed whether elevations in the obstructive or central sleep apnea index or the presence of Cheyne-Stokes breathing are associated with decompensated and/or incident heart failure. Methods: We conducted a prospective, longitudinal study of 2,865 participants derived from the Osteoporotic Fractures inMen Study, a prospectivemulticenter observational study of community-dwelling older men. Participants underwent baseline polysomnography and were followed for a mean 7.3 years for development of incident or decompensated heart failure. Ourmain exposureswere the obstructive apnea-hypopnea index (AHI), central apnea index (CAI ≥5), and Cheyne-Stokes breathing. Covariates included age, race, clinic site, comorbidities, physical activity, and alcohol and tobacco use. Measurements and Main Results: CAI greater than or equal to five and presence of Cheyne-Stokes breathing but not obstructive AHI were significant predictors of incident heart failure (adjusted hazard ratio [HR], 1.79; 95% confidence interval [CI], 1.16-2.77 for CAI≥5) (HR, 2.23; 95% CI, 1.45-3.43 for Cheyne-Stokes breathing). After excluding those with baseline heart failure, the incident risk of heart failure was attenuated for those with CAI greater than or equal to five (HR, 1.57; 95% CI, 0.92-2.66) but remained significantly elevated for those with Cheyne-Stokes breathing (HR, 1.90; 95% CI, 1.10-3.30). Conclusions:Anelevated CAI/Cheyne-Stokes breathing, but not an elevated obstructive AHI, is significantly associated with increased risk of decompensated heart failure and/or development of clinical heart failure in a community-based cohort of older men.
