title: [Сomprehensive evaluation of new diagnostic criteria for progression of essential hypertension stage II].
abstract: The aim of the study was to improve the diagnosis of essential hypertension (EH) stage II in patients with different circadian blood pressure profile through a comprehensive analysis of various parts of hemodynamics. The diagnostic capabilities of compression-decompression test by using of original method angio-tensio-rheo-baro-graphy (ATRBG), which is based on volume-impedance dependence of forearm tissue's hyperemia, peculiarities of the changes of microcirculation of the nail bed and central venous pressure (CVP) have been studied in 92 patients with EH stage II depending on the circadian rhythm of blood pressure. The results of using ATRBG may indicate that the arterial hypertension is combined with venous one in the majority of patients with EH stage II. We have discovered the inverse relationship between the increasing of CVP level and the decreasing of density of functional capillaries in the patients with low (non-dipper) and negative (night-picker) circadian index of arterial pressure that can be proposed as new diagnostic criteria of progression of EH.
