Aim. To assess the changes and variability of standardized mortality rates (SMR) from various types of chronic ischemic heart disease (CIHD) in the Russian Federation and its regions in 2014-2023.Material and methods. The Rosstat data analysis of CIHD mortality for 2014-2023 was carried out in accordance with the Rosstat Brief No­menclature of Death Causes. The calculations were performed using the computer program "Calculation and Analysis of Mortality Rates and Years of Life Lost due to Premature Mortality in the Subjects of the Rus­sian Federation". The European standard of the World Health Orga­nization (1976) was used to calculate the SMR. The calculation of mean regional SMRs and their comparison were performed using the SPSS 26.0 program.Results. The mean regional SMR from CIHD for 2014-2023 decreased from 205,93±67,93 to 175,81±62,36 per 100 thousand population. Regional variability of SMR from CIHD as a whole did not undergo significant changes as follows: in 2014, the maximum SMR exceeded the minimum by 8,5 times; in 2023 — 8 times. The number of regions with I25.0-I25.9 SMR of 0 increased from 8 to 19 during the analyzed period. The coefficient of variation of regional SMRs from CIHD in 2023 is higher than in 2014. No uniform trends in the SMR for all regions were recorded for any CIHD types.Conclusion. Significant and increasing regional variability of SMR from certain CIHD types is recorded. No standardization of clinical, morphological and statistical principles for coding certain CIHD types as the underlying cause of death hinders the assessment and analysis of mortality changes. Consequently, this inhibits the development of measures to reduce them reliably and effectively. Typification of coding approaches will serve to improve the quality of analysis of CIHD mortality statistics and the subsequent adoption of targeted management decisions.
