Participants of nuclear-powered submarine accident liquidation and special risk units' veterans participating in surface nuclear weapon tests as well as in liquidation of their consequences have been examined. It has been established that functional state of this category of people is difficult to interpret only in the context of radioactive irradiation effect or injuring stress factor exposure. This state is determined by a complex of psychotraumatic factors tending to become aggravated and characterizing by their individual significance and absolute or relative insolvability. In most representatives of this category the disease is manifested by psychopathologic syndrome of neurotic disorders (low spirits, emotional lability, asthenia, anxiety) and somatic disturbances as dysfunction of the cardiovascular, respiratory, digestive and other systems. The results obtained provide the pathogenetic substantiation of efficient ways and methods for rehabilitation of the special risk units' veterans. The data prove the necessity of appropriate correction of cardiovascular disorders in practically healthy servicemen residing under conditions of psychoemotional tension.
