title: [The cardiovascular system in liquidators of consequences of the Chernobyl atomic power station accident].
abstract: Liquidators of consequences of the Chernobyl atomic power station accident were found to have cardiovascular regulatory disorders in the late period. A late pressure reaction of systolic blood pressure to exercise was caused by cardiac rhythm rigidity due to the sick sinus syndrome. High exercise tolerance and delayed ischemia were indicative of diminished total peripheral resistance due to the impaired responsiveness of alpha-adrenoblockers in the arterial vessels and of the development of neurocirculatory dystonia. Cardiovascular functional changes in the liquidators are not attended by the higher morbidity rates of hypertensive disease.
