Computerized auditory cognitive training to improve cognition and functional outcomes in patients with heart failure: Results of a pilot study

Feasibility and efficacy of computerized auditory cognitive training (ACT) was examined among patients with heart failure (HF). Background: Individuals with HF have four times increased risk of cognitive impairment, yet cognitive intervention studies are sparse. Methods: A pilot randomized controlled design was used. Results: The ACT group (. n=9) and control group (. n=8) had similar baseline characteristics. Seven participants (78%) completed ≥18 hours of ACT. Medium effect sizes were observed for improved cognition as indicated by auditory processing speed (. d=0.78), speech processing (. d=0.88), and working memory (. d=0.44-0.50). Small effect sizes were found for improved functional outcomes including HF selfcare (. d=0.34), Timed Instrumental Activities of Daily Living (. d=0.32), Six-Minute Walk Test (. d=0.38) and Short-Form-36 (. d=0.22) relative to controls. Conclusion: Results indicated ACT is feasible among persons with HF. Despite a small sample size, ACT showed potential for improved speed of processing and working memory and improved functional outcomes, and warrants further exploration.
