Heart failure (HF) is associated with high levels of sleep disturbance and sleep disorders, including insomnia, periodic limb movements during sleep, and sleep disordered breathing. Recent studies underscore the importance of disturbances in sleep, a multidimensional biobehavioral phenomenon, to the pathophysiological processes associated with the development of HF, excess morbidity and mortality, and decrements in quality of life and functional performance. Managing disturbed sleep requires specific self-care strategies that must be incorporated into other self-care tasks associated with HF. Decrements in functioning associated with disturbed sleep may also have a negative impact on the self-care capacity and self-care behaviors of people with HF. The purposes of this article are to evaluate the state of the science relative to the nature of sleep disturbance experienced by people with HF and to discuss the implications of sleep, sleep disorders, and sleep-promoting interventions for self-care of people with HF.
