The investigation was dedicated to associations between anxious or depressive conditions and clinical features of essential hypertension (EH) on a model of in-patients undergoing treatment in Groznyy Municipal Hospital No 1. The study found a high frequency of depressive and anxious disturbances in this group of patients (36.4% and 41.6%, respectively). Comparison of patients with mental disorders with mentally healthy controls showed that anxious (to a greater degree) and depressive disorders were in a strong association with crises within the course of EH as well as high prevalence of left ventricular hypertrophy and elevated level of blood catecholamines.
