[The prediction of the development of circulatory encephalopathy in hypertension patients with the initial manifestations of brain blood supply insufficiency].

The principal risk factors conducive to the development of cardiovascular diseases in young and middle-aged subjects with chronic cerebrovascular insufficiency due to Stage I or II essential hypertension were under study. Thirty-four male patients with the initial manifestations of inadequate blood supply to the brain (IMIBS), 35 male patients with stages I or II dyscirculatory encephalopathy (DE), and 32 and 33 female patients with the same conditions, respectively, were examined. Hypertensive cerebral crises were significantly more frequent in DE patients of both sexes than in IMIBS patients, and a tendency to a longer standing of arterial hypertension was observed in DE patients as against those with IMIBS. The results of the examinations evidence that excessive body mass, hypokinesia and psychoemotional stress, as well as an 'accumulation' of risk factors were conducive to the development of DE in essential hypertension patients with IMIBS. Basing on the discriminant analysis of risk factors, the authors have developed a method for predicting the development of DE in patients with IMIBS of a hypertensive origin. Use of this method will essentially improve the efficacy of prophylactic and therapeutic measures in IMIBS patients.
