Aim:
To evaluate changes in cognitive functions in patients with coronary heart disease before and after coronary artery bypass grafting (CABG) in a planned manner.
Material And Methods:
The study included 192 patients divided into 3 groups: in group 1 patients (n=88) underwent standard CABG; in group 2 (n=61) different methods of CABG were used; a control group consisted of 43 people. MMSE, FAB, Clock drawing test, Shultz tables, semantic verbal fluency, Wechsler adult intelligence scale were used for neurological testing.
Results And Conclusion:
Postoperative cognitive dysfunction develops 3.2 times more often in patients after standard CABG. Patients in the group with a differentiated approach show a trend towards the improvement of cognitive functions after surgery.
