- W2891960140 abstract "Introduction: Approximately 25% to 75% of heart failure (HF) patients have sleep apnea (SA), which may contribute to brain changes that are associated with decreases in attention, memory, and executive function. Unfortunately, there is a dearth of research that explores how SA may contribute to brain changes and cognition within the HF population. Thus, the purpose of this study is to examine the relationships between the apnea-hypopnea index (AHI), grey and white matter brain volumes, and neuropsychological test scores of attention, memory and executive function. Hypothesis: HF patients with higher AHI would have decreased brain volumes and neuropsychological test scores. Methods: Using a cross-sectional design, we sampled 28 HF patients; 13 HF patients had AHI ≥ 10 and 15 HF patients had AHI <10. Eighty percent were male (n=12) and their mean age was 68 (SD = 5). We evaluated AHI with a portable multichannel sleep-monitoring device, brain volumes with voxel-based morphometry method T-1 weighted images f..." @default.
