Epidemiological aspects of the prevalence of coronary heart disease in an open urban population: gender differences

The aim. To determine gender differences in the prevalence of coronary heart disease in an open urban population.Material and Methods. For a one-stage epidemiological study in an open urban population, a representative sample of 25-64-year-old residents was formed from the electoral lists of the Central Administrative District of Tyumen (n=2000) using a “random” mathematical method. The response rates of the study were 85.0% among men and 70.3% among women. The conclusion about the presence of coronary artery disease was carried out according to strictly standardized epidemiological methods. Definite CHD (strict criteria) and possible CHD (lax criteria) were distinguished based on the extended criteria.Results. The prevalence rates of CHD in the open 25-64-year-old population were 12.4% in men and 10.0% in women. According to strict epidemiological criteria, the prevalence of painless ischemic heart disease prevailed in men; the prevalence of angina pectoris prevailed in women (predominantly at a young age). According to non-strict criteria, possible myocardial ischemia prevailed in men and women.Conclusion. The results can serve as a scientific basis for primary prevention of coronary artery disease and also necessitate identification of the gender differences in the study of the profile of conventional and non-conventional risk factors and their relationships with the prevalence of CHD in an open population of the urbanized Siberian city.
