[Spirometry and bicycle ergometry in the evaluation of work capacity of coal miners with ischemic heart disease].

The article deals with results obtained in examination covering miners who faced myocardial infarction and assessing their performance. Spirometry and bicycle ergometry appeared to detect changes in aerobic threshold even in the cases when the effort tolerance is not compromised. The materials obtained bring to a conclusion that the miners after myocardial infarction include subjects with lower functional resources and a higher share of those with reserved aerobic capacity.

[Effects of work conditions in coal mines on prevalence of ischemic heart disease among miners].

Occurrence of coronary heart disease among workers of Donbass coal mines more than 2 times exceeds the values for matched general population (groups of males aged 20-49). Peculiarities of working environment and industrial process were proved to be risk factors for coronary heart disease among the miners.

[The prevalence of arterial hypertension among coal miners].

Incidence of arterial hypertension (AH) in the miners is dependent on the length of service, growing significantly with its duration, as well as on the mining geological and mining engineering features of the mining plants, as evidences by surveys employing epidemiological and mathematical-statistical methodological approaches. The miners in the mining plants with steeply pitching coal, working under more unfavourable labour conditions, were found to experience particularly high AH rates. In all age groups of miners a high percentage of individuals with borderline AH was revealed.

[The scientific support of public health institutions with the technology for the sociomedical assessment of the health of miners].

Analysis of the scientific research activities of the Donetsk Research Centre of Occupational Hygiene and Prevention of Traumatism was carried out, which offered a basis for the development of technology for medicosocial assessment of morbidity involving temporary unfitness for work, occupational morbidity, invalidism and mortality among coal miners, risk for development of nonoccupational and occupational diseases, prevalence of IHD and other non-infectious diseases, functional status of the organism according to psychophysiological indices for those going to work in the mine, as well as of the state of undue fatigue and overstrain experienced by the miners. The analysis permits the above technology to be inaugurated in the health care establishments and research institutes.
