[Major results of a long-term prospective study of a male population].

The results of a prospective study of a Moscow population of males aged 50-59, represented in 4 independent samples (each numbering 500 subjects), are reported. Two examinations were conducted at a 6.5-year interval, and mortality was reviewed in the examined population. High incidence of coronary heart disease (CHD) and its risk factors was established at first screening, and increased further during the next decade. The need for a differential approach to the assessment of CHD risk factors and high mortality rates, and also to the planning of preventive programs with regard to age, presence of CHD and its risk factors, is emphasized.
