The condition of the microcirculatory channel of the nail bed of the upper extremities and changes of central venous pressure in patients with the second stage of essential hypertension depending on the structure of the diurnal rhythm of arterial pressure

Abstract

The peculiarities of changes of the microcirculation of the nail-bed and central venous pressure (CVP) have been presented in the poper in patients the with 2nd stage of essential hypertension depending on different variants of the circadian rhythm of arterial pressure. An inverse interdependence has been established between the level and a decrease of the specific gravity of the functioning capillaries in the patients with a low (non-dipper) and negative (night-picker) diurnal index of arterial pressure that con be used as diagnostic criteria of a high risk of possible complications of essential hypertension.
