DYNAMICS AND STRUCTURE OF THE NUMBER OF PATIENTS HOSPITALIZED FOR CORONARY ARTERY DISEASE IN THE RUSSIAN FEDERATION IN 2014–2023

Highlights Coronary artery disease is one of the leading causes of hospitalization of patients. An assessment of the dynamics and structure of the number of hospitalizations over a ten-year period will allow us to determine the factors influencing the level of hospitalization of patients with various forms of coronary artery disease, and the degree of influence of each of the factors in practical healthcare. Aim. To evaluate the dynamics and structure of the number of patients hospitalized for coronary artery disease in the Russian Federation in 2014–2023. Methods. The analysis of Rosstat data on the structure of the number of hospitalizations (planned andemergency) for coronary heart disease among adults (18 years and older), contained in Table 2000 FFSN No. 14, was carried out and an assessment of their dynamics for 2014–2023 was performed. The statistical analysis was performed using the packages SPSS 26.0 (IBM Company) and Excel (Microsoft for Microsoft Windows). Results. The number of hospitalizations of patients with coronary artery disease for the period 2014–2023 decreased by 20% (from 1,310 per 100,000 adult population to 1,054 per 100,000 adult population). The proportion of patients hospitalized for coronary artery disease in the structure of general hospitalization decreased from 7.7% to 6.7%. The number of hospitalizations of patients for chronic forms of coronary artery disease (I25) decreased by 0.7%, for myocardial infarction (I21–22) – by 9%; for angina pectoris (I20) – by 32%. The number of cases of hospitalization of patients for postinfarction cardiosclerosis (I25.8) increased by 31%. The share of hospitalizations of patients for chronic forms of coronary artery disease in the structure of cases of hospitalization of patients for coronary artery disease increased from 35.1% in 2014 to 43.3% in 2023; for MI – increased from 12.7% in 2014 to 14.4% in 2023; for angina – decreased from 50% in 2014. up to 42.2% in 2023, the change in the structure of hospitalization of patients for coronary artery disease is statistically significant (p<0.0001). Significant volatility in the number of hospitalizations for various forms of coronary artery disease was registered during the pandemic of the new coronavirus infection COVID-19. Conclusion. There has been a steady decrease in the number of hospitalizations of patients for coronary artery disease and a change in the structure of hospitalization of patients for coronary artery disease with a continuing predominance of hospitalizations for chronic forms of coronary artery disease. The identified trends may be related both to approaches to the organization of medical and diagnostic care, and to the specifics of accounting for the causes of hospitalization according to the ICD-10 codes. Due to the large number of factors influencing the hospitalization of patients with various forms of coronary artery disease, it is advisable to determine the degree of influence of each of them in the conditions of practical healthcare in the Russian Federation.
