Some aspects of the relative risk of death from myocardial infarction of the female population of the Republic of Dagestan

The article analyzes the relative risk (RR) of death from myocardial infarction (MI) in women in the ecological zones of the Republic of Dagestan (RD). An epidemiological study of all female deaths from MI in RD in 2011–2020 was carried out taking into account their residence in cities and rural areas of various ecological zones. The analysis of the RR of mortality by altitude belts indicates that the foothills and mountains of RD are areas of increased risk of death from MI for the female population, while on the plains the same indicator is insignificantly lower. The highest mortality rate from MI among women was recorded in the south of the mountainous ecological zone (8.1 cases per 100,000 female population) with an RR of 1.3.
Aim: analysis of the relative risk (RR) of death from myocardial infarction (MI) among women of ecological zones of the Republic of Dagestan (RD).
Materials and methods: An epidemiological study of all female deaths from MI in RD in 2011–2020 was carried out taking into account their residence in cities and rural areas of various ecological zones.
Results: An analysis of the RR of mortality in the high-altitude zones indicates that the foothills and mountains of the Republic of Dagestan are areas of increased risk of death from MI among female population. However, in the plain the same indicator is insignificantly lower. The highest mortality rate from MI among women was registered in the south of the mountain ecological zone (EZ) (9.1 cases per 100,000 female population) with RR 1.4. These data can be considered evidence of the effect on the risk of death from myocardial infarction among the female population from the southern mountainous areas with a sharply continental climate, characterized by high-altitude hypoxia, affecting the oxygen supply processes in the myocardium.
Conclusion: The areas of increased RR of mortality from myocardial infarction among the female population of rural areas include the high-mountainous regions of the southern mountains of the Republic of Dagestan.
