The Correlation of β-Adrenoreactivity of Erythrocyte Membranes with Clinical and Laboratory Parameters in Patients with Resistant Hypertension in the Presence and Absence of Type 2 Diabetes Mellitus

Abstract

The peculiarity of the conjugation of β-adrenoreactivity of membranes (β-ARM) erythrocyte, as an indicator of the state of autonomic regulation of the cardiovascular system, with other clinical and laboratory indicators in drug-resistant arterial hypertension (RAH) with the absence and presence of type 2 diabetes mellitus (DM2) was investigated. It was shown that patients with RAH, regardless of the presence of DM2, were characterized by reduced adrenoreactivity, while the beta-ARM index of erythrocytes was more than 2 times higher than the reference values. The intergroup difference in the mean values of beta-ARM erythrocytes and the frequency of cases of exceeding the established reference values by this indicator did not have significant differences. In RAH, regardless of the presence of DM2, the beta-ARM erythrocytes index of erythrocytes is statistically significantly associated with the variability of blood pressure, the volume of daily diuresis and increased contractile capacity of the left ventricle. In addition, in the presence of DM2, the association of β-ARM erythrocyte with an increase in left ventricular elastance, heart rate variability, duration of arterial hypertension and DM2 was revealed. Thus, with the development of RAH in humans, the β-ARM erythrocyte indicator can be a new biomarker for personalized assessment of the activity of autonomic regulation of the cardiovascular system. CD2 expands the conjugacy of β-ARM erythrocyte with clinical and laboratory parameters.
