Neuropsychological dynamics in patients with type 2 diabetes mellitus undergone coronary artery bypass grafting

Abstract

AIM: The study was aimed at evaluation of hospital neuropsychological dynamics in ischemic heart disease patients with comorbid type 2 diabetes mellitus (T2DM) undergone on-pump coronary artery bypass grafting. MATERIALS AND METHODS: 14 from a total of 37 examined patients had T2DM. Diabetic patients were found to have lower attention parameters prior to the intervention in comparison to non-diabetic controls. At days 7-10 after the surgery all patients demonstrated deterioration of cognitive functions. RESULTS: We observed deeper deterioration in diabetic patients, regarding attention, memory, sensorimotor speed and quantity of erroneous test responses, as measured against individuals with normal glucose tolerance. CONCLUSIONS: Diabetic patients undergone coronary artery bypass surgery show lower cognitive characteristics when compared to controls without T2DM, suggesting this cohort to be a high-risk group for further cognitive decline.
