[Hemostasis disorders in coal miners].

Findings are that coal miners having long contact with vibration instruments and coal dust develop endothelial dysfunction, increased platelets aggregation, hypercoagulation and lower anticoagulation activity. The hemostasis disorders revealed could result in earlier coronary atherosclerosis development in workers exposed to vibration.

[Effects of local vibration on development of ischemic heart disease in miners of South Kuzbas]. / Vliianie lokal'noi vibratsii na razvitie ishemicheskoi bolezni serdtsa u shakhterov iuga Kuzbasa.

The incidence of ischemic heart disease (IHD) and risk factors of its genesis have been studied in 380 miners of a control group non-exposed to industrial vibration. Constitution type and a number of phenotypic signs have been determined for all examined workers with hemostatic indices defined in 60 miners before and after the performance of vibrational load test. High incidence of IHD, arterial hypertension and hyperholesterolemia have been detected in the miners working with vibration instruments and hemostatic disorders predisposing to ischemic heart disease have been revealed. In the miners of vibrodangerous occupations suffering from ischemic heart disease, hypersthenic constitution type determined by Rees-Eysenc index less than 92.2 and the height below 170 cm was found to occur more frequently.

Occurrence of coronary heart disease and its risk factors are studied in individuals working with vibration instruments--in drift miners, miners of breakage face--and in 390 reference group miners who never faced occupational vibration. Findings are higher incidence of coronary heart disease, arterial hypertension and hypercholesterole mia in the miners working with vibration instruments. The main group miners suffering from coronary heart disease demonstrated more frequent hypersthenic constitutional type.
