Analysis of the mortality rate dynamics due to circulatory system diseases in the kemerovo region for the period 2017-2021.

Highlights Every year more than 4 million deaths are registered from cardiovascular diseases (CVD), which is 46% of all deaths. Over the past 40 years, a downward trend in mortality from CVD has been revealed. However, the COVID-19 pandemic period has changed the statistics of indicators of both total mortality and mortality from CVD. Aim . To analyze the mortality rate (MR) features from CVD in the Kemerovo Region (KR) from 2017 to 2021, in comparison with the Russian Federation (RF) rate. Materials and Methods . Mortality rates of the adult population of KR and RF for the period 2017–2021 were taken from the official sources. The KR/RF dynamics was approximated by a linear trend using Microsoft Excel 2010. Results. Over the past 5 years (from 2017 to 2021) the increase in mortality from CVD was 58.2% in the KR and in the RF – 9%. In 2017 the mortality rates in the RF were higher than in the KR and they levelled off by 2018. However, in the period 2019-2021 there was a sharp increase rate in the KR, in comparison with the RF. According to Kemerovo Statistical Office, the mortality rate from CVD in the region in 2021 was 10.8% higher than in 2020. The structure of mortality from CVD in 2021 in the KR had 52.8% of death cases due to coronary heart disease and 32.6% were caused by the cerebrovascular disease. During the COVID-19 pandemic (2019–2021) the first 3 places among the causes of total mortality in the KR were occupied by CVD (46.3% – 49.4% – 49.3%, respectively), neoplasms (17.1% – 15.2% – 13.2%) and external causes of death (9% – 7.7% – 6.5%). In the structure of total mortality cases the COVID-19 share is 2% in 2020 and 6.4% in 2021, respectively, which raised them to the 4th place in 2021. Conclusion. An increase in mortality rates in the region may indicate both the real causes of death, they can also be associated with the peculiarities the death cases coding and the impact of clinical and organizational technologies as well as the aging of the population. All the data require further in-depth research.
