[Incidence of ischemic heart disease and its main risk factors among males aged 35-59 years in Tallin].

In a simultaneous epidemiological examination according to the standard programme of 20% of a random sample of unorganized males aged 35-59 years and living in Tallin (n = 2208), coronary heart disease (CHD) was established in 12.1%, its incidence increasing with age. 66.1% of the individuals with detected CHD were not aware of the disease, 28.7% had not visited the local out-patient centre previously. The prevalence of the major risk factors in the population was 80.7%; 38.6% of the subjects had two risk factors or more. Some risk factors were found to correlate with age, the nature of occupation and the educational level. The individuals with CHD more frequently showed arterial hypertension, excessive body weight and lipid metabolism disorders and less commonly the absence of risk factors as compared with individuals without this pathology. The study may serve as an informative basis of planning measures for primary and secondary prophylaxis of CHD in the population at the greatest risk, i. e. males aged 35-59 years.
