Background. The accepted threshold of insulin resistance value in arterial hypertension (AH) is absent, thus it is relevant to determine its degree in patients with AH, and to determine the interaction between the insulin resistance (IR) syndrome and the target organs injury. The purpose of our study was to set the threshold of IR in patients with AH, to define association between the IR parameters, presence of diastolic dysfunction and the state of aorta elasticity. Materials and methods. Investigation included 229 patients with AH and type 2 diabetes mellitus (DM), as well as 108 patients with the isolated AH. There were used clinical, instrumental, biochemical (HOMA-2 model, HOMA-IR indices), statistical methods. Results. The course of the isolated AH and AH with concomitant type 2 DM is associated with IR development, that it is well-proven in the model of HOMA-2 (р < 0.001). In patients with comorbid pathology the sensitiveness of peripheral tissues to insulin depends on severity of AH (р < 0.001). Presence of IR in HOMA-IR model was revealed in patients with the isolated AH in 26.6 % of cases. The level of plasma insulin grows substantially, and the tissues sensitiveness to insulin declined at the third type of diastolic dysfunction (р < 0.05). The coefficients of aorta elasticity have a reverse correlation with all parameters of НОМА-2 model determined by the levels of glucose (р < 0.001), insulin (p < 0.05), coefficient НОМА-IR (p < 0.05) and direct association with the degree of peripheral tissues sensitivity to insulin (p < 0.01). Conclusions. The threshold of IR by HOMA-2 model in patients was set at the level of 1.87; the increase of aorta inflexibility and diastolic dysfunction severity depend on IR severity.
