Key result
In heart failure patients, 67% had at least mild cognitive impairment, which was associated with older age, lower education, and lower 6-minute walk test scores (R2 = 0.27).
Why the study?
Cognitive impairment in heart failure has mostly been studied in single countries and specific healthcare settings, leaving sociodemographic and clinical predictors of global cognitive impairment and its dimensions unclear.
Population
605 heart failure patients enrolled in Sweden, Italy, Israel, The Netherlands, Germany, and the United States
Design
Secondary analysis of baseline trial data

Cognitive impairment is highly prevalent (67%) in heart failure patients and is associated with older age, lower education, and reduced exercise capacity.
Vellone et al. (2019) conducted a cross-sectional in Heart failure (n=605). Sociodemographic and clinical factors was evaluated on Cognitive impairment (Montreal Cognitive Assessment score) (R2 = 0.27). In heart failure patients, 67% had at least mild cognitive impairment, which was associated with older age, lower education, and lower 6-minute walk test scores (R2 = 0.27).
