Abstract Background:

Among the various pathologies that affect the elderly, Heart Failure (HF) stands out. Recently, an attempt has been made to verify the existence of cognitive impairment associated with HF.

Objectives:

To compare the cognitive performance of elderly people with heart failure with that of age-matched individuals without this pathology. Check the existence of marked impairment in some cognitive functions in the clinical group.

Methods:

The sample consisted of 78 elderly people, whose inclusion criterion was the presence of HF and no HF (control group); age over 60 years, both sexes, and any level of education. The control group consisted of 37 individuals (with a median age of 68 years - Interquartile range of 12) and the HF group, with 41 individuals (with a median age of 67 years - Interquartile range of 11). The subjects were matched in terms of education level, with a predominance of elderly people with 0 to 4 years of education (65.9% in the Clinical Group and 59.5% in the Control Group).

Eleven neuropsychological tests covering cognitive functions were used:

attention, language, memory, mood, and executive function. Statistical analysis was performed using SPSS software, version 23, with a significance level of 5%. The Chi-square test and the Mann-Whitney test were applied.

Results:

The results showed significant differences between the groups, mainly in executive functions, which include the ability to plan, switch, and recall previously stored information.

Conclusion:

Our study showed differences between the cognitive performance of elderly people with HF and elderly people without HF. The main alteration was found in the so-called executive functions, attention, and memory.
