[Epidemiology of ischemic heart disease among the rural male population of Karaganda Province].

All WHO requirements and recommendations fulfilled, a one-stage epidemiological study was conducted in a nonorganized population of rural males, aged 30 to 59 years. With the aid of random numbers tables 1450 persons were selected, of whom 1340 were examined (92.4%). The majority of the examined (82.3%) were engaged in physical labour in different branches of agriculture, and only 14.4%--in clerical work. Ischaemic heart disease was found in 55 persons (4.1%), among them 26 (47.2%) were newly diagnosed cases. Among the clarks ischaemic heart disease was found to be more than twice as frequent (7.2%) as in those engaged in hard (3.3%) and moderately hard (3.7%) physical labour. A correlation was established between the incidence of the disease and such leading risk factors as arterial hypertension, smoking, excessive body weight, limited exercises and hypercholesterolemia. The conducted epidemiological study proves the necessity of the development and realization of preventive measures against ischaemic heart disease among the rural population.
