Abstract: The peculiarities of cardiohemodynamics, microcirculation, and microvasculature are presented in the article; their correlation with significance of the oxidative stress, the level of antioxidative blood potential and endothelial function in the isolated course of essential hypertension and in conditions of its comorbidity with duodenal peptic ulcer was carried out. The structural-functional indices and parameters of cardiohemodynamics, indices of microcirculation and microvasculature, the content of the intermediate and the final products of lipid peroxidation in the blood, activity of enzymes of the antioxidant protection system and indices of endothelial function were estimated. It was established that the presence of the remodeling left ventricle (a significant increase of the left heart chambers, symmetrical myocardial hypertrophy) with the unchanged contractile function, and maximal intensity of both resistivity of the peripheral vascular system (р <0.001), and disorders of microcirculation and microvasculature on the perivascular, vascular, and intravascular levels (р <0.001) is typical of the patients with the comorbid course of essential hypertension. The next results showed that manifestations of oxidative stress were the most significant (the increase of diene conjugates and malondialdehyde content (p <0.001) among the patients with the combinative pathology. The index of the antioxidative ability of blood serum was low in these patients (p <0.001); besides, it had the negative correlation relationship with the index of the total changes of microhemocirculation and microvasculature (r = -0.467; p <0.05). At the same time the index of ristomycin- inducted platelet aggregation as reflection of the changed endothelial function and a marker of the thrombogenic risk was also the highest in case of the comorbid course of essential hypertension (p <0.001); besides, its positive correlation relationship with the index of the total changes of microhemocirculation and microvasculature (r = +0.465; p <0.05) was established.
