[The occupational aspect of sudden cardiac death in coal miners].

By means of epidemiological, clinico-functional, experimental, pathomorphological, histological and mathematical-statistical methods the authors showed that hard physical work under conditions of heating microclimate promoted quick development and advance of coronary heart disease in deeply working coal miners. Negative dynamics of sudden coronary death (SCD) rate was established, its pathophysiological mechanisms were specified. SCD risk factors were singled out and arranged accordingly to their importance. SCD in miners was suggested to be considered as professionally conditioned state.
