Abstract

OBJECTIVES:

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.
