ASSOCIATIONS OF POLYMORPHISMS NOS3-T-786C, MTHFR-C667T, P2RY12-T-744C, (GPIBα) -C482T AND GENE INTERACTIONS IN MACROANGIOPATHIES IN PATIENTS WITH COMBINED HYPERTENSION AND TYPE DIABETES MELLITUS 2

OBJECTIVEThe aim: To establish the role of allelic polymorphisms NOS3-T-786C, MTHFR-C667T, P2RY12--744C, (GPIbα)-C482T in the development of vascular lesions in patients with hypertension and diabetes mellitus type 2. PATIENTS AND METHODSMaterials and methods: The study included 100 patients with hypertension and diabetes mellitus type 2 (main group) and 50 patients without type 2 diabetes (control group). Patients underwent echocardiography, color duplex scanning of extracranial, brachiocephalic and femoral vessels. The distribution of allelic polymorphisms was investigated by isolation DNA from leukocytes and polymerase chain reaction (PCR). RESULTSResults: The risk of vascular damages increases 2-fold when carrying all 4 risk alleles in monozygotic genotypes of polymorphic loci in patients with hypertension with concomitant type 2 diabetes (p
