The proportion of patients with cognitive impairment after coronary artery bypass surgery: an 8-month follow-up study.
The aim of this study was to investigate cognitive function after coronary artery bypass surgery and the association of this with surgical variables. All male patients scheduled for elective surgery, aged 40-64 years, mean age 54 +/- 6 (n = 104), and participating in a randomized rehabilitation study, were included. A comprehensive psychodiagnostic examination was conducted preoperatively, 2, and 8 months postoperatively. The assessment of change was conducted using tertiles, defined according to population norms. More patients revealed improvement than impairment, and practically no significant associations with surgical variables were found.
