May support cognitive screening in chronic HF; leaves open effects on management and outcomes.
Background-Cognitive impairment is a recognized consequence of heart failure; however, there are no neuropsychological batteries with documented psychometric data in the chronic heart failure population.Aims-To document the psychometric properties of a brief neuropsychological battery in a chronic heart failure sample. Methods-TheRepeatable Battery for the Assessment of Neuropsychological Status, Trail Making Test Part A and Part B, and letter fluency was administered to a sample of individuals with chronic heart failure.Results-Eighty individuals with stable heart failure participated in this study.Individuals with chronic heart failure scored significantly lower than expected age and education adjusted norms in the domains of attention (p < 0.001), memory (p < 0.001), language (p < 0.001), executive function (p < 0.001), and psychomotor speed (p = 0.02).Scores on the tests of memory and executive function correlated to functional status (r = 0.28, p = 0.02 and r = 0.29, p = 0.03, respectively).Acceptable convergent validity and test-retest reliability were documented for this battery. Conclusion-The neuropsychological battery had adequate reliability and validity in individuals with chronic heart failure.
