[Detection and analysis of clinico-pathogenetic variants of the labile stage of hypertension using mathematical methods of image recognition].

The method of cluster analysis was used for automatic classification of patients with the labile stage of hypertensive disease according to 15 parameters reflecting the condition of hemodynamics and its regulation. Two groups differing in the principal factors of high arterial pressure maintenance were distinguished. Clinical and physiological analysis of the distinguished groups was conducted on the basis of the furosemide test.
