背景资料：心力衰竭（HF）的人有显着较低的睡眠数量和质量比人没有HE本文的目的是提出一个概念模型，描述如何睡眠不佳可能有助于不充分的自我保健和不利的结果在人与HF.Aims：我们的首要假设是，睡眠影响自我保健和结果通过其对认知的影响。基于其他人的工作，我们概述了一个概念模型，说明即使是短暂的睡眠中断也会阻止睡眠相关的恢复过程，并导致认知功能障碍，特别是在25-50%存在认知障碍的HF患者中。睡眠不足可能足以导致认知功能障碍，特别是在25-50%的患有认知功能障碍的HF患者中。睡眠不足可能足以损害认知，达到干扰有效HF自我护理实践中涉及的高阶功能的水平。通过这些机制，睡眠不足可能会导致不良结果，如低健康相关的生活质量和更大的风险，计划外的hospitalization.Conclusion：所提出的模型（1）桥梁的物理，神经心理和行为现象，（2）提出了一种机制，睡眠不足影响白天的行为，（3）是经验检验。探索干扰睡眠的因素可能会改善HF患者的自我护理和结局。(C)2009年欧洲心脏病学会。Elsevier B.

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.
