[Prevention of circulatory system diseases in underground mining workers].

The article covers results of preventive measures in workers engaged into underground mining. Those measures are aimed to prevent occupationally mediated health disorders resulting in circulatory diseases. The prophylaxis was proven effective on premorbid condition--that was demonstrated in reliable decrease of cause-effect relationship intensity for health disorders in workers subjected to prophylactic measures. Transitory disablement morbidity due to cicrulatory system diseases decreased. Situational modelling of risk changes for the studied group demonstrated changes of diseases risk under medical prophylactic measures. After the prophylaxis, the risk demonstrated 3.1 times decrease.
