ReviewThe mind of a failing heart: a systematic review of the association between congestive heart failure and cognitive functioning.
Congestive heart failure (CHF) is a frequent complication of most diseases of the heart. CHF is associated with impairment in several aspects of the quality of life of patients, including mood and cognitive performance. Early reports indicated that patients with CHF display deficits in memory and other intellectual abilities, although the clinical relevance of these findings remains unclear. ⋯ The results of the present review highlight the enormous paucity of systematic information about the association between CHF and cognitive functioning, with only five studies reporting data suitable for analysis. We expect that new case-control and cohort studies will be designed to confirm the presence of cognitive impairment in patients with CHF and trust that this information will improve the management of CHF patients and our understanding of the mechanisms associated with cognitive decline in later life.
