Psychomotor speed as a predictor of functional status in older chronic heart failure (CHF) patients attending cardiac rehabilitation

Research output: Contribution to journalArticlepeer-review


Background: The association among psychological, neuropsychological dysfunctions and functional/clinical variables in Chronic Heart Failure (CHF) has been extensively addressed in literature. However, only a few studies investigated those associations in the older population. Purpose To evaluate the psychological/neuropsychological profile of older CHF patients, to explore the interrelation with clinical/functional variables and to identify potential independent predictors of patients' functional status. Methods: This study was conducted with a multi-center observational design. The following assessments were performed: anxiety (Hospital Anxiety and Depression Scale, HADS), depression (Geriatric Depression Scale, GDS), cognitive impairment (Addenbrooke's Cognitive Examination Revised, ACE-R), executive functions (Frontal Assessment Battery, FAB), constructive abilities (Clock Drawing Test, CDT), psychomotor speed and alternated attention (Trail Making Test, TMT-A/B), functional status (6-minute walking test, 6MWT) and clinical variables (New York Heart Association, NYHA; Brain Natriuretic Peptide, BNP; left ventricular ejection fraction, LVEF; left ventricular end diastolic diameter, LVEDD; left ventricular end diastolic volume, LVEDV; tricuspid annular plane systolic excursion, TAPSE). Results: 100 CHF patients (mean age: 74.9±7.1 years; mean LVEF: 36.1±13.4) were included in the study. Anxious and depressive symptoms were observed in 16% and 24,5% of patients, respectively. Age was related to TMT-A and CDT (r = 0.49, p<0.001 and r = -0.32, p = 0.001, respectively), Log-BNP was related to ACE-R-Fluency subtest, (r = -0.22, p = 0.034), and 6MWT was related to ACE-R-Memory subtest and TMT-A (r = 0.24, p = 0.031 and r = -0.32, p = 0.005, respectively). Both anxiety and depression symptoms were related to ACE-RTotal score (r = -0.25, p = 0.013 and r = -0.32, p = 0.002, respectively) and depressive symptoms were related to CDT (r = -0.23, p = 0.024). At multiple regression analysis, Log-BNP and TMT-A were significant and independent predictors of functional status: worse findings on Log-BNP and TMT-A were associated with shorter distance walked at the 6MWT. Conclusions: Psychological and neuropsychological screening, along with the assessment of psychomotor speed (TMT-A), may provide useful information for older CHF patients undergoing cardiac rehabilitation.
