Aim. To assess the influence of visceral obesity (VO) on cognitive function (CF) of patients after coronary artery bypass surgery (CBG).Material and methods. Totally, 90 patients included, selected to 2 groups (gr.) by the parameter “waist/hip circumference”. To 1st gr. we included 46 patients with VO, to 2nd — 44 patients without VO. CG assessed via software and hardware by “Status PF” (Kemerovo), the tests on memory, attention, cognition and neurodynamics were done.Results. In comparison of CF between the groups, in 1 gr. there were lower results comparing to the 2nd before CBG, after 2 weeks and 6 months. In timeline of CF assessment of 1 gr. there was decline of imagery memory (p=0,014) in 2 weeks after CBG. In 6 months after CBG there was improvement of CF in gr. 1 comparing to preoperation data, incl. statistically significant improvement of memory, cognition and neurodynamics. While comparing the CF parameters in 2nd group, there was improvement by “simple analogy” test (p=0,00028) and neurodynamics (the total delays decreased (p=0,033) in the reaction on moving object) even in 2 weeks after CBG. In 6 months after CBG the patients from 2nd group showed improvement of attention, cognition and neurodynamics.Conclusion. Patients with VO have significantly worse CF and the risk of permanent cognition disorders development after CBG, than those without VO.
