Implication

May warrant cognitive screening in advanced CHF; hypothesis-generating for whether EF optimization mitigates impairment.

Key Points

The study aims to explore the cognitive impairment in elderly patients with congestive heart failure compared to healthy older adults.
Examined 50 CHF patients with functional class III/IV and 30 healthy older controls.
Conducted assessments using CAMDEX, CAMCOG, MMSE, and various neuropsychological tests.
Analyzed the relationship between cognitive scores and left ventricular ejection fraction using logistic regression.
Cognitive performance of CHF patients was significantly worse than controls across all assessments.
27/50 CHF patients scored lower than 24 on MMSE compared to 10/30 controls (p=0.073).
36/49 CHF patients had CAMCOG scores below 80 compared to 9/30 controls (p<0.001).

Structured PICO

Population

80 older adults, comprising 50 consecutive patients admitted to hospital with congestive heart failure (functional class III/IV, LVEF < 45%) and a convenience sample of 30 older adult controls (LVEF > 65%) assessed at an outpatient geriatric medicine service in São Paulo, Brazil.

Intervention

Congestive heart failure (exposure)

Comparator

Older adult controls without congestive heart failure (LVEF > 65%)

Outcome

Cognitive functioning assessed via CAMDEX, CAMCOG, MMSE, Trail Making A and B, Digit Span, Digit Symbol, and Letter Cancellation Test

Congestive heart failure with reduced ejection fraction is associated with significant cognitive impairment in older adults, which correlates with the degree of left ventricular dysfunction.
