[Changes in the course of atherosclerosis occurring over a 25-year period in the male population of 9 cities of the CIS and Baltic countries].

The trends in atherosclerosis presentation were followed up pathomorphologically in a two-stage epidemiological survey performed in 9 cities of CIC and Baltic states at 25-year interval. The investigations were conducted in accordance with WHO program. Stage 1 (1963-1968) covered 6121 cases, stage 2 (1985-1989) included 9201 cases. The material was collected on the condition of aortas and coronary arteries from 20-59-year-old males who were residents of the cities of Irkutsk, Yakutsk, Tallin, Tartu, Riga, Kharkov, Yalta, Ashkhabad, Bishkek. The 2-stage examinations gave evidence for growing severity of atherosclerosis. Risk factor analysis demonstrated an increase in the percentage of males with diabetes mellitus and arterial hypertension, in the percentage of overweight males and of those with atherosclerosis engaged in mental work. It is found that atherosclerosis undergoes changes within the life of one generation (for 20-25 years).
