Key result
Cardiac patient and partner ratings of everyday cognitive difficulties align and link to visual memory.
Why the study?
Cognitive decline in candidates for cardiac bypass surgery likely affects everyday cognitive functioning, but relationships between self-report, significant other report, and cognitive tests are unclear.
Cross-Sectional (n=69)
In candidates for cardiac bypass surgery, self-reported and significant-other-reported cognitive difficulties are similar and correlate with visual memory performance.

Patient- and informant-ratings of everyday cognition may diverge from objective tests in bypass candidates; leaves open their clinical utility for predicting decline.
Candidates for cardiac bypass surgery often experience cognitive decline. Such decline is likely to affect their everyday cognitive functioning. The aim of the present study was to compare cardiac patients' ratings of their everyday cognitive functioning against significant others' ratings and selected neuropsychological tests. Sixty-nine patients completed a battery of standardised cognitive tests. Patients and significant others also completed the Everyday Function Questionnaire independently of each other. Patient and significant other ratings of patients' everyday cognitive difficulties were found to be similar. Despite the similarities in ratings of difficulties, some everyday cognitive tasks were attributed to different processes. Patients' and significant others' ratings were most closely associated with the neuropsychological test of visual memory. Tests of the patients' verbal memory and fluency were only related to significant others' ratings. Test scores of attention and planning were largely unrelated to ratings by either patients or their significant others.

Elliott et al. (2009) conducted a cross-sectional in Candidates for cardiac bypass surgery (n=69). Everyday Function Questionnaire ratings vs. Standardised cognitive tests was evaluated on Relationship between patient ratings, significant other ratings, and neuropsychological test scores. Patient and significant other ratings of everyday cognitive difficulties were similar and most closely associated with visual memory test performance.
