Little is known about excessive daytime sleepiness (EDS) in heart failure (HF). The aim of this cross-sectional descriptive study was to describe the prevalence of EDS and factors associated with it in HF. A secondary purpose was to explore the correlates of fatigue. We enrolled a consecutive sample of 280 adults with a confirmed diagnosis of chronic HF from three outpatient settings in the northeastern United States. Patients with major depressive illness were excluded. Clinical, sociodemographic, behavioral, and perceptual factors were explored as possible correlates of EDS. Using an Epworth Sleepiness Scale score > 10, the prevalence of EDS was 23.6%. Significant determinants of EDS were worse sleep quality (p = .048), worse functional class (p = .004), not taking a diuretic (p = .005), and lack of physical activity (p = .04). Only sleep quality was associated with fatigue (p < .001). Sleep-disordered breathing was not significantly associated with EDS or with fatigue. These factors may be amenable to intervention.
