Cardio-vascular stress-reactivity as the indicator of hypertension development

The opportunity of experimental modelling the development of an arterial hypertension is shown at long (4 months) stay normotensive rats in conditions of isolation. The structure of cardiovascular answers to stress in close image depends on a degree of arterial hypertension development, adequately changing ac-cording to a level of hypertension status. Latent (1 month of the isolated residing) and steady forms of disease (4 months of isolation) are characterized by different changes in cardio-vascular stress-reactance. The initial stage of hypertension is accompanied by reorganizations in a vascular component of stress (on duration), and the steady form - both vascular (on duration), and intimate (on amplitude and duration) components of stress. This fact testifies to different mechanisms of formation and progressing stress-induced arterial hypertension. That fact, that vascular stress-reactance varies already at initial stage of disease, being shown identically animal with expressed hypertensive status, specifies an opportunity of us-ing the given characteristic as the indicator of prehypertension.
