Abstract

Abstract: Objective To explore the influence of sleep duration and social isolation on cognitive frailty in elderly patients with chronic heart failure(CHF). Methods From January 2024 to January 2025, a total of 302 elderly patients with CHF in Nanjing First Hospital were investigated by the general information questionnaire, sleep duration assessment, Lubben Social Network Scale-6, Frailty scale, Montreal Cognitive Assessment scale, and Clinical Dementia Rating scale. LASSO regression was used to screen variables and logistic regression was used to analyze the relationship of sleep duration,social isolation with cognitive frailty. Results There were 145(48.0%) elderly CHF patients presenting with cognitive impairment. Multivariable logistic regression analysis showed that after adjusting for confounding factors, the risk of cognitive frailty in patients with sleep duration >8 hours was 3.606 times higher than that in patients with sleep time of 6 to 8 hours (P<0.05). The risk of cognitive frailty in patients with social isolation was 3.360 times higher than that in patients without social isolation (P<0.05). Conclusions Prolonged sleep duration (>8 hours) and social isolation both increase the risk of cognitive frailty in elderly patients with CHF.

Key words: heart failure, aged, cognitive frailty, sleep duration, social isolation
