[STRUCTURAL, FUNCTIONAL, AND VEGETATIVE CONDITIONS OF PATIENTS WITH STABLE ARTERIAL HYPERTENSION, ITS MASKED FORM, AND WHITE COAT HYPERTENSION].

The character of changing of functional and vegetative characteristics in different clinical variants of arterial hypertension thus far remains obscure. The aim of this work was to study patients with stable arterial hypertension (SAH), its masked form (MH), and white coat hypertension (WCH). We examined 125 patients who were divided into these 3 groups based on results of 24 hr AP monitoring by cardiac rhythm measurement and echocardiography. The study revealed different risk factors of each of the three forms of AH. The main risk factors of WCH are age and disturbed rhythm variability, those of MH are overweigh, obesity, and myocardial dysfunction, while SAH is associated with the advanced age, overweight, obesity, the history of concomitant cardiovascular diseases, and disordered daily profile of AP. It is concluded that different clinical variants of AH result from the changes in the functioning of cardiovascular and vegetative nervous systems associated with different risk factors.
