Abstract
Background and Purpose: Identification of the effects of sleep disturbances on the quality of life could result in proper treatment of
patients with heart failure. This study aimed to investigate the relationship between sleep disorders and erectile dysfunction, depression
and quality of life in male patients with systolic heart failure.
Methods: This correlational study was conducted on 100 male patients with systolic heart failure selected by convenience sampling.
Data were collected using Epworth Sleepiness Scale (ESS), STOP-Bang questionnaire, Pittsburgh Sleep Quality Index (PSQI),
Minnesota Living with Heart Failure questionnaire (MLHFQ), Center for Epidemiologic Studies Depression Scale (CES-D) and
International Index of Erectile Function (IIEF-5). Data analysis was performed using descriptive statistics, Pearson’s correlationcoefficient
and linear regression model.
Results: In this study, sleep quality (P<0.001) and possibility of obstructive sleep apnea (OSA) (P=0.001) were significantly associated
with depression and could explain 32.6% of variance in depression. In addition, possibility of OSA (P=0.006) was associated with
erectile dysfunction and could explain 12% of variance in erectile dysfunction. Also, possibility of OSA (P=0.001) and sleep quality
(P<0.001) had a statistically significant correlation with quality of life and could explain 36% of variance in quality of life.
Conclusion: According to the results of this study, poor sleep quality and sleep-disordered breathing were negatively correlated with
mood, sexual function and overall quality of life in male patients with systolic heart failure. Therefore, proper screening and treatment
of sleep disorders in patients with heart failure is of paramount importance.
