[Psychophysiological factors and their role in assessing the work capacity of arterial hypertension patients].

The homeostatic and information tests were used for the first time ever in addition to the MMPI method to evaluate the effects of psychophysiological factors on working capacity of 250 patients with arterial hypertensions and 127 normal subjects. Optimum performance in the solving of a homeostatic search problem was shown to be twice as rare in hypertensive patients, as compared to the normal subjects. A clear-cut relationship was established between the quality of information processing as evidenced by the information test, and the patients' psychological characteristics, BP values and the extent of cerebral hemodynamic changes. An index capable of quantitative characterization of the working capacity of hypertensive patients is proposed.
