Key result
CHF and cognitive impairment are linked in older adults, driving worsening outcomes through hypoperfusion.
Why the study?
There is evidence supporting an association between congestive heart failure and cognitive impairment in older adults, with unclear mechanisms and clinical implications.
Cognitive impairment in older adults with heart failure negatively impacts complex disease management, suggesting that identifying these patients may improve clinical outcomes.
Supports integrated cardio-cognitive assessment in older adults; leaves open whether hypoperfusion-targeted interventions alter outcomes.
The purpose of this review is to present the evidence supporting an association between two common medical conditions in older adults, congestive heart failure and cognitive impairment. Potential mechanisms of this interaction include hypoperfusion, cerebral emboli and electrolyte imbalances. Successful management of heart failure often involves complex medication and dietary regimens and lifestyle adjustments. Cognitive impairment can negatively impact on this management, leading to a progressive cycle of worsening heart failure, further cognitive impairment, disability and increased mortality. Interventions to identify heart failure patients with impaired cognition may improve these clinical outcomes.

A 2007 study conducted a review in Congestive heart failure and cognitive impairment. Congestive heart failure was evaluated. Congestive heart failure and cognitive impairment are associated in older adults, potentially interacting through hypoperfusion and leading to a progressive cycle of worsening clinical outcomes.
