Abstract
The role of heart failure (HF) in mortality rates is ambiguous, and much depends on assessment criteria and accounting potential.Aim. Using medical certificates of cause of death (MCCD), to assess rates of HF, taking into account different types of coronary artery disease (CAD), sex, age and place of death.Material and methods. Data on deceased persons for 2020 were obtained from the electronic database of the Main Department of Civil Registry Office of Moscow Oblast, using the 4-digit codes of the International Classification of Diseases, Tenth Revision (ICD-10). All deaths with CAD codes (I20-25) were selected. A total of 23193 deaths were included in the analysis. The codes and verbal descriptions of complications were assessed and 3 groups were formed: without indication of heart failure (HF), with indication of HF (without chronic HF) and CHF in MCCD. Comparison of the average age of deceased, the proportion of women and men, the detection rates of certain CAD types and the place of death was carried out. Using logistic regression, the probability of chronic HF/HF as a death cause was determined, taking into account other factors.Results. Any HF was indicated in 78,9% of the MCCD (acute CAD — 44,5%, chronic CAD — in 89,1%). Chronic HF was indicated in 27% of the MCCD (men, 30,9%; women, 22,9%; p<0,0001). The highest values were obtained in heart aneurysm — 47%; in other chronic CAD forms — slightly more than a third of the MCCD. HF was not indicated in men in 23,3% of deaths, in women — in 19%; maximum — 90% in “other acute CADs”; minimum — 11% in heart aneurysm. Average age of deceased was 73,6±12,5 years (men, 68,8±10,5; women, 78,4±12,5) (p<0,0001). In all CAD forms, the average age of deceased was significantly higher in subgroups with chronic HF than in groups with (not chronic HF) or without HF. Age, sex, CAD type, place of death (in-hospital deaths were ~2 times less common).Conclusion. According to the MCCD data, chronic HF is not the dominant complication leading to death. The results obtained require clarification in studies based on primary medical documentation.

Abstract
Aim. To analyze the contribution of cardiac causes to all-cause mortality, to characterize the differences in standardized mortality rates (SMRs) in Russian regions, as well as to identify promising directions for improving establishment of cardiovascular death and its coding.Material and methods. We used the Federal State Statistics Service (Rosstat) data on the mortality rate and the average annual population in one-year age groups for 2019. To calculate the SMR, the European Standard Population was used. For each cardiac death, the SMR from 23 causes was calculated, which were combined into 4 groups, and for each of these groups, the regional mean and standard deviation of SMR in Russian regions were estimated.Results. In 2019, the cardiac SMR in Russian regions was 301,02±77,67, which corresponded to 30,5±5,8% of all death causes. At the same time, the coefficient of variation of regional cardiac SMR was 25,8%. In general, in 60,9±13,8% of cases, the cause of cardiac death was chronic diseases, mainly related to atherosclerosis. The proportion of deaths from acute types of coronary artery disease was 17,3±9,7%, deaths not associated with atherosclerosis (heart defects, myocardial diseases, etc.) — 17,5±8,2%, deaths associated with hypertension — 4,2±5,2%. The coefficient of variation of regional SMR was 34,66, 64,47, 50,99 and 122,7, respectively.Conclusion. Significant regional differences in SMR from certain cardiac causes and groups of causes, as well as their contribution to mortality pattern, were revealed. It is necessary to continue the research on the methodology of statistical recording of certain cardiovascular diseases.
