[Day-by Day Blood Pressure Variability: Methodological Aspects, Prognostic Value, Effects of Antihypertensive Therapy].

In this article we present problems of prognostic value of day-by-day blood pressure (BP) variability, its role in development and progression of damage of target organs in arterial hypertension, and impact on risk of cardiovascular, cerebral-vascular complications, and mortality. We also discuss methodological aspects of assessment of day-by-day BP variability. The article contains literature data on effects of antihypertensive therapy on variability of home BP, and consideration of evidence base of possibilities of the fixed amlodipine/perindopril combination for lowering day-by-day BP variability.

[Sympathetic Nervous System Activation in Pathogenesis of Development of Essential Hypertension and Its Role in Target-Organs Damage in Young and Middle Aged Adults: the Cardioprotective Capabilities of Bisoprolol].

The article discusses various mechanisms of developmentt and progression of arterial hypertension in young and middle aged adults. It emphasizes the predominant role of hypersympathicotonia in the development of the disease in this category of patients. Various mechanisms are considered, by means of which the increase of activity of the sympathetic nervous system leads to elevation of arterial pressure and potentiates early damage of target organs, first of all, damage of the heart. The data of numerous studies demonstrating pronounced cardioprotective effects of a highly selective representative of the class of ß-blockers bisoprolol in young and middle aged hypertensive patients are presented.
