PILOT STUDY RESULTS OF THE INFLUENCE OF CITICOLINE AND PIRIBEDIL ON COGNITIVE FUNCTION IN PATIENTS WITH ISCHEMIC HEART DISEASE AFTER CORONARY ARTERY BYPASS SURGERY

Aim. To reveal cognitive deficit after coronary artery bypass, the influence of citicoline, piribedil on the state of higher cerebral functions in the early and late periods after surgery.Material and methods. The study included 94 patients with ischemic heart disease. All patients were divided into 3 groups. Patients of the first group (n=30) were prescribed citicoline as a cerebral neuroprotective drug. Patients of the second group (n=32) had piribedil in addition to standard therapy. Patients of the control group (n=32) had only a standard treatment without any neuroprotective drugs. All patients underwent coronary artery bypass surgery. The cognitive function was assessed before, 10 days after and six months after coronary artery bypass.Results. Patients of group 1 and 2 had achieved pre-surgical levels of cognitive tests results 6 months after coronary artery bypass. The control group had achieved initial levels only in three tests: visual memory (immediate simulation; p=0.008), categorical association (p=0.002), clock drawing test (Wilcoxon test; p=0,005), while other indices were reduced in comparison with the initial ones.Conclusion. The obtained results allow considering the studied drugs as a protectors of cognitive function after surgery. Randomized controlled double-blind studies on large samples are needed to confirm these results.
