Heart failure (HF) is a serious and growing public health problem on the world. Among its many features there are low quality of life (QOL) and excessive daytime sleepiness (EDS) due to sleep disorders which impairs its quality. It was identified the EDS and sleep quality in patients with HF and their SDE was correlated to their QOL. Among the 52 subjects of the study, 23 patients completed the study (13M), with average age of 60.5 years, functional class (FC) II and III, ejection fraction ≤45%. Subjects were evaluated for their quality of sleep, EDS and QOL. Questionnaires were applied in the form of interview by using the SF−36 for QOL, Pittsburgh Sleep Quality Index Questionnaire for quality of sleep and Epworth Sleepiness Scale for SDE. A total of 60.86% of the sample showed poor sleep quality. Correlating QOL to EDS, significant results were obtained in the pain (p=0.04 and r=−43), vitality (p=0.05 and r=−0.40) and social functioning (p=0.003 and r=-0.59). The sample has a poor sleep quality, with presence of SDE negatively correlated with QOL in aspects of vitality, pain and social functioning.
