Education and the risk factors of ischaemic heart disease.

Screening for the risk factors of ischaemic heart disease among the male residents of the district of Prague 4 aged 40--49 years was undertaken under the "National multifactorial primary preventive study of myocardial infarction and stroke". Of the 11 091 men invited, 5395 met the defined criteria and were admitted to the study. 58% of them were included in the risk group. The level of attained school education was ascertained at the initial examination. The lowest percentage of persons with hypercholesterolaemia, overweight, elevated blood pressure and smokers was found among university graduates. The results are compared with data of other studies and possible causes of the findings are discussed.
