Insights
This study investigated BrainHQ, a computerized cognitive training program, for heart failure patients experiencing memory loss. Results will inform new therapeutic approaches for this common comorbidity.
Area of Science:
- Neurology
- Cardiology
- Gerontology
Background:
- Memory loss is prevalent in heart failure patients, predicting mortality.
- Few effective interventions exist for cognitive impairment in heart failure.
- This study addresses a critical unmet need in heart failure management.
Purpose of the Study:
- To evaluate the efficacy of computerized cognitive training (BrainHQ) for memory and neurotrophic factor improvement in heart failure patients.
- To assess the cost-effectiveness of the BrainHQ intervention.
- To explore the influence of depressive symptoms and genetics on BrainHQ's effectiveness.
Main Methods:
- A 3-arm randomized controlled trial involving 264 heart failure patients.
- Participants assigned to BrainHQ, crossword puzzles (active control), or usual care.
- Data collected at baseline, 10 weeks, 4 months, and 8 months, with intent-to-treat analysis.
Main Results:
- This section is not available in the provided abstract.
Conclusions:
- The research will yield novel insights into BrainHQ's potential to enhance memory and brain-derived neurotrophic factor in heart failure.
- If effective, BrainHQ offers a disseminable therapeutic strategy for a significant heart failure comorbidity.
Background:
Memory loss is an independent predictor of mortality among heart failure patients. Twenty-three percent to 50% of heart failure patients have comorbid memory loss, but few interventions are available to treat the memory loss. The aims of this 3-arm randomized controlled trial were to (1) evaluate efficacy of computerized cognitive training intervention using BrainHQ to improve primary outcomes of memory and serum brain-derived neurotrophic factor levels and secondary outcomes of working memory, instrumental activities of daily living, and health-related quality of life among heart failure patients; (2) evaluate incremental cost-effectiveness of BrainHQ; and (3) examine depressive symptoms and genomic moderators of BrainHQ effect.
Methods:
A sample of 264 heart failure patients within 4 equal-sized blocks (normal/low baseline cognitive function and gender) will be randomly assigned to (1) BrainHQ, (2) active control computer-based crossword puzzles, and (3) usual care control groups. BrainHQ is an 8-week, 40-hour program individualized to each patient's performance. Data collection will be completed at baseline and at 10 weeks and 4 and 8 months. Descriptive statistics, mixed model analyses, and cost-utility analysis using intent-to-treat approach will be computed.
Conclusions:
This research will provide new knowledge about the efficacy of BrainHQ to improve memory and increase serum brain-derived neurotrophic factor levels in heart failure. If efficacious, the intervention will provide a new therapeutic approach that is easy to disseminate to treat a serious comorbid condition of heart failure.
