To examine how self-reported sleep quality and daytime symptoms are associated with selected domains of cognitive function among individuals with heart failure (HF).
HF patients suffer from poor sleep quality and cognitive decline. The relationship between sleep and cognition has not been well documented among individuals with HF.
In this descriptive, cross-sectional study, 68 individuals with HF (male: 63%, mean age = 72 years, SD = 11) completed sleep questionnaires and a neuropsychological battery.
Participant had mean Pittsburgh Sleep Quality Index score of 5.04 (SD = 2.8). Regression analyses demonstrated neither sleep quality or excessive daytime sleepiness (EDS) were related to cognitive function, but daytime dysfunction was related to lower letter fluency and attention index.
Contrary to some earlier reports, subjective sleep and EDS in this group of individuals was not associated with cognitive decline.
探讨心力衰竭（HF）患者自我报告的睡眠质量和日间症状与认知功能特定领域之间的关联。
HF患者睡眠质量差且认知功能下降。HF患者中睡眠与认知之间的关系尚未得到充分记录。
在这项描述性横断面研究中，68例HF患者（男性占63%，平均年龄 = 72岁，标准差 = 11）完成了睡眠问卷和一套神经心理学测试。
参与者的匹兹堡睡眠质量指数平均得分为5.04（标准差 = 2.8）。回归分析表明，睡眠质量或日间过度嗜睡（EDS）均与认知功能无关，但日间功能障碍与较低的字母流畅性和注意力指数有关。
与一些早期报告相反，该组患者的主观睡眠和EDS与认知功能下降无关。
