Background: Persons with heart failure (HF) have significantly lower sleep quantity and quality than persons without HE The purpose of this article is to propose a conceptual model describing how poor sleep may contribute to inadequate self-care and untoward outcomes in persons with HF.Aims: Our overarching hypothesis is that sleep affects self-care and Outcomes through its effects on cognition. Building on the work of others, we outline a conceptual model that illustrates that even transient sleep disruption prevents sleep-related restorative processes and contributes to cognitive dysfunction-especially in the 25-50% of HF patients with existing cognitive impairment. Poor sleep may be sufficient toto cognitive dysfunction-especially in the 25-50% of HF patients with existing cognitive impairment. Poor sleep may be sufficient to impair cognition to a level that interferes with higher order functions involved in effective HF self-care practices. Through these mechanisms, inadequate sleep may contribute to poor outcomes such as low health-related quality of life and greater risk of unplanned hospitalization.Conclusion: The proposed model (1) bridges physical, neuropsychological and behavioral phenomena, (2) suggests a mechanism by which poor sleep affects daytime behavior, and (3) is empirically testable. Exploring factors that interfere with sleep may improve self-care and outcomes in persons with HF. (C) 2009 European Society of Cardiology. Published by Elsevier B.V. All rights reserved.
