UNLABELLED: AIM. To comparatively analyze neuropsychological parameters in patients with coronary artery disease (CAD) depending on the presence of type 2 diabetes mellitus (DM) and to evaluate their relationship to carbohydrate and lipid metabolic parameters. SUBJECTS AND METHODS: Fifty-two male patients with type 2 DM (mean age 58.0 ± 5.7 years) and 46 male patients without this condition (mean age 57.1 ± 6.2 years) were examined. Besides standard clinical examination, neurophysiological testing and determinations of glycated hemoglobin (HbA(1c),) and insulin concentrations, QUICKI index, and blood lipid profile were made. RESULTS: The patients with DM differed from those without DM in the lower speeds of sensorimotor reactions during neurodynamic testing and in worse attention values. In the patients with type 2 DM, the worse neuropsychological status was associated with the higher plasma concentrations of glucose, insulin, HbA(1c), total cholesterol, low-density lipoproteins, and triglycerides and with the lower levels of high-density lipoproteins. These relationships were not observed in the patients without DM. CONCLUSION: The patients with CAD concurrent with DM had a worse neurophysiological status than those without DM. Only the DM group demonstrated a relationship between cognitive impairments and carbohydrate metabolic markers. Carbohydrate and lipid metabolic disturbances may be assumed to make a negative contribution to the development of cognitive impairments in patients with CAD concurrent with type 2 DM.
