[Arterial hypertension and chronic hemodialysis]

Basing on the literature data and their own observations of patients with chronic hemodialysis the authors have analysed the pathogenesis, course, hemodynamic shifts and possibilities of purposeful treatment in terminal uremia. Besides two variants of the hypertension course (controlled and noncontrolled), a third type has been revealed--hypertension difficult to control, in the pathogenesis of which, as well as in the noncontrolled variant, an important role is played by the activization of the renin-angiotensin system. Hemodynamic mechanizms of an abrupt change in the arterial pressure (acute hypotension and hypertensive crisis) in the process of hemodialysis are analysed.
