Clinical Trial Summary

The objective of this project is to assess the effects of combined physical exercise and cognitive training interventions on cognitive and brain health in patients with heart failure (HF). Also, the role of sex on the effects of the interventions will be assessed.


Clinical Trial Description

Cognitive impairment (CI) affects up to 50% of patients with heart failure (HF), and is associated with high mortality rates, poor quality of life, reduced functional capacities, and an overwhelming economic burden in Western countries. Non-pharmacological strategies could help enhance cognition in HF patients with CI. Combined physical exercise and cognitive training interventions have recently shown promising enhancement effects on cognition in patients with cardiovascular risk factors and mild cognitive impairment. The effects of combined interventions have never been tested in HF. The main objective is to assess the effects of combined physical exercise and cognitive training interventions on cognition in patients with HF. Secondary objectives include: to characterize baseline and intervention-related changes in cerebral autoregulation and vasoreactivity and to assess the role of sex on the effects of the interventions. Two-hundred and sixteen participants (36 men and 36 women/group) with stable HF regardless of aetiology and LVEF will take part in this study. All participants will have signed a written consent form before taking part in the study. Patients will be stratified according to sex and LVEF (FEVG < 40% et FEVG > 40%), and will be randomly assigned to one of the 3 following study arms: 1) Combined physical exercise and cognitive training; 2) Physical exercise alone; and 3) Usual medical care. ;
