Abstract

To determine the association between heart failure (HF) and cognitive change and dementia. Systematic search of three electronic databases was performed and 29 eligible studies involving approximately 3 million participants were identified. Twelve studies examined dementia and 20 cognitive change, but only a subset of studies could be included in the meta-analysis. These findings indicated that HF was not significantly associated with dementia (n=8, hazard ratio [HR] 1.18, 95% confidence interval [CI] [0.93, 1.50]), but increased the risk of cognitive impairment (n=3, HR 1.80, 95%CI [1.14,2.86]) . Additionally, HF was associated with poorer mean cognitive performance in global cognition (Hedges' g -0.73, 95%CI [-1.12, -0.35]), memory (Hedges' g -0.57, 95%CI [-0.72, -0.42]), executive function (Hedges' g -0.58, 95%CI [-0.72, -0.43]), attention/speed (Hedges' g -0.50, 95%CI [-0.63, -0.37]) and language (Hedges' g -0.61, 95%CI [-1.05, -0.17]). Patients with HF perform worse on all cognitive tests, and have an increased risk of cognitive impairment. These findings highlight the need for clinicians to consider cognition as part of routine care for patients with HF. [Abstract copyright: Copyright © 2021. Published by Elsevier Inc.]
