Based on the population data of the Department of Statistics for the city of Almaty, Republic of Kazakhstan for the period 2019–2020, the structure and dynamics of deaths from diseases of the circulatory system were analysed, and age survival was studied using the method of constructing survival tables and the Kaplan-Meier method. The number of deaths from circulatory system diseases among Almaty residents in 2020 increased by 1.5 times compared to 2019. At the same time, the proportion of deaths from diseases of the circulatory system among women decreased and increased among men. The leading cause of death in diseases of the circulatory system has changed in dynamics: in 2019, the first rank was occupied by cerebrovascular diseases (I60–I69), and in 2020 by coronary heart disease (I20–I25). A significant (p ≤ 0.001) shift of the median survival time in diseases of the circulatory system towards a decrease (73.5 years → 70.9 years) was revealed. Also, significant (p ≤ 0.001) differences in the survival rate of Almaty residents with circulatory system disease (CSD) in 2020 by gender were found: the survival rate in the male population is significantly lower compared to the female population (66.1 years vs 77.5 years). Survival rates for chronic rheumatic heart disease (I05–I09), pulmonary heart and pulmonary circulatory disorders (I26–I28), arterial, arteriolar and capillary diseases (I70–I79) have increased, but survival rates have decreased for diseases I10–I15), coronary heart disease (I20–I25), other heart diseases (I30-I52), cerebrovascular diseases (I60–I69), diseases of veins, lymphatic vessels and lymph nodes (I80–I89). The main conclusion that can be drawn is that during the COVID-19 pandemic, in comparison with the previous year, the number of deaths increased (by 1.5 times) and the nosological structure of causes of death and survival in diseases of the circulatory system among residents of Almaty changed. To a greater extent, the increase in deaths occurred due to deaths from coronary heart disease (I20-I25), cerebrovascular diseases (I60-I69) and other heart diseases (I30–I52). There is also a greater increase in deaths from CSD in the male population. It is recommended to conduct an additional study to verify the assumption that mortality from diseases of the circulatory system is related to the level of anxiety/depression, as well as studies to assess the accounting of deaths from diseases of the circulatory system of comorbid COVID-19-patients.
