Purpose: To determine and describe variables explaining spatial memory performance in patients with chronic HF. Theoretical/conceptual framework: Spatial memory, defined as the ability to find one's way in familiar surroundings, remembering where belongings have been put, and where they are usually kept, may be impaired in HF due to poor oxygenation. Subjects: A comparative study of 414 participants (249 HF, 102 medical control, and 63 healthy control) completed a neuropsychological test battery. Mean age of the HF patients was 62.9 yrs; 63% were men; mean LVEF 28%. Control groups were matched on premorbid intellect and education; healthy control (HC) patients were younger and had significantly more men. Methods: Measurement of spatial memory performance included the Design Copy Test which has 5 designs (circle, diamond, intersection, rectangle, and cube) that participants were asked to copy and then reproduce after 20 minutes. The 3 groups were compared using ANCOVA adjusting for age, intellect, and education; multiple regression analysis was used (HF sample only) to determine variables associated with spatial memory performance. Results/Conclusions: Constructional praxis scores were poorer in the HF patients compared to MC and HC participants however this did not reach significance (mean scores total Design Copy 8.7, 8.9, 9.0, p = .70; recall Design Copy 7.5, 7.8, 8.3, p = .77, respectively). Design Copy Test Z-scores indicated that 6% of HF patients had scores indicative of spatial memory impairment on the total score and 12% on recall total score. A subset of HF patients were impaired, deficits being substantial, with some patients unable to copy simple figures. Multiple regression of constructional recall (R2 = .10) indicated age, gender, and NYHA were significant explanatory variables of spatial memory performance. The subset of HF patients should be examined further to determine variables and testing methods identifying those at greatest risk.
