20-year monitoring of acute cardiovascular diseases in population of a large industrial city in the West Siberia (an epidemiological study)

Aim. To reveal trends in incidence rates acute cardiovascular diseases (ACD ) in a large industrial city of the West Siberia. Materials and methods. Studies on WHO programs "Acute Myocardial Infarction Register" and "MONICA" have been performed in three districts of Novosibir sk. The diagnostic categories were detected without difference. The observa tion covered stable population of 500000 residents aged 25-64 years. Trends in the myocardial infartion (MI) mortality, morbidity and lethality were a nalysed for 1977-1996. Results. The above trends were stable except for 1986 when MI mortality, mo rbidity and lethality decreased and 1988 and 1994 and 1994 when they went u p. The reduction was due to 7-year prevention program While the rise was co nsequent to discontinuation of the preventive measures. Major risk factors of ischemic heart disease, according to screenings conducted in 1984, 1988 and 1994 remained at about the same level. Social stress closely correlates with a rise in MI morbidity and mortality. The latter in 1994 grew owing t o higher rates of MI mortality and morbidity among the oldest men and femal es of different age groups. Conclusion. Urgent intensification of prophylactic measures is needed both at the populational level and the level of high risk strategy.
