Assessment of cognitive impairment in patients with ONMC on the background of coronary artery bypass grafting

Abstract

Relevance. Coronary artery bypass grafting (CABG) is one of the main methods of surgical treatment of coronary heart disease and is performed in order to restore perfusion and improve the functional state of the myocardium. According to the literature, CABG has a high percentage of neurological complications. About 80 % of patients in the postoperative period have mild or moderate brain damage, which is manifested primarily by cognitive decline. One of these complications is an acute violation of cerebral circulation (ONMC).Study aim. To compare patients with ONMC after CABG and patients with ONMC, which were based on other reasons for the leading impaired cognitive functions and to assess cognitive impairment.Material and methods. The severity of cognitive impairment in patients with a history of CABG was studied using the MoCA test scale, comparing the results obtained with the data of stroke patients without CABG.Results. Significantly more often patients (ONMC with CABG) tests on visual-constructive skills, on the skills of "Delayed reproduction" performed worse. Memory".Conclusion. In patients with ONMC with CABG in the anamnesis, visual disturbances were observed 2 times more often. Based on the data obtained, it can be concluded that CABG surgery significantly affects the degree of impairment of visual-constructive skills and delayed reproduction (memory) in ONMC, which is the basis for further, more in-depth study of this problem.
