title: [Blood pressure profile in patients with hyper- and hypotension: effect of physiological stresses].
abstract: Responses to physiological stresses, relationship between character and severity of these reactions and parameters of 24-hour blood pressure (BP) profile were studied in patients with arterial hyper- and hypotension. Disturbed regulation of BP in hyper-, and hypotension was associated not only with pronounced spontaneous BP variability but also with hyper- and hypotensive responses of BP to natural and modeled orthostatic, psychoemotional, physical and nutritional stresses. Frequency of hypotensive episodes in patients with hypertension was similar to that of hypertensive episodes in patients with hypotension. The use of stress tests facilitated assessment of BP responses to various loads, determination of clinical value of hemodynamic changes and possibilities of correction of detected disturbances.
