[Ischemic heart disease as a cause of death in occupational groups of workers].

The authors studied the ischemic heart disease spread as a lethality cause in 5673 workers, retired due to a disease (general, occupational disease and accident). The workers in 2.9 per cent were found to die of ischemic heart disease with a 15 years length of service and at the age of 60. The miners die in 0.2 per cent of ischemic heart disease, teachers--in 5.1 per cent, drivers--8.9 per cent, engineers (management personnel)--in 13.5 per cent etc. The deceased of ischemic heart disease in 2 per cent have worked in favourable working conditions, in 13 per cent--in contact with poisons, in 20 per cent--with unfavourable microclimate, in 41 per cent with mental work etc. The work in unfavourable working conditions and nervous-psychic strain was proved to appear as a risk factor for the origination of ischemic heart disease.
