Abstract

Introduction. At present, especial attention is paid to the diagnostic issues of postoperative brain damage. The
diagnostic value of electroencephalographic (EEG) study parameters for early postoperative cognitive dysfunction
in patients undergoing coronary artery bypass grafting (CABG) was studied in this investigation.

Material and methods. The study enrolled 85 male patients with coronary artery disease, requiring surgical
myocardial revascularization. All patients underwent neuropsychological and EEG 3–5 days before surgery and
7–10 days after CABG.

Results. It was found that the high values of the beta rhythms power and shifting the theta-beta ratio, as well as the
presence of carotid artery stenosis less 50% increase risk of developing cognitive impairment in early postoperative
CABG period.

Conclusion. The study demonstrated the ability to use EEG to assess the functional state of the cerebral cortex
after cardiac surgery and predict cognitive deficits in the postoperative period.
