Aim. To study the dynamics of the number of coronary artery bypass grafting (CABG) and percutaneous coronary interventions (PCI) in some countries and Russia in the 2000–2018..Methods. The data of the official statistics of the Organization for Economic Cooperation and Development on the number of CABG and PCI were used. The countries that have provided data for most of the analyzed years and have more than 30 CABG per 100,000 population (22 countries) were selected. Data on the number of interventions in Russia were obtained from the CNIIOiIZ and Bakulev NMICSSH. The US data are obtained from the literature.Results. In most countries, the number of CABG decreased by 2018.The United States, Denmark, Finland, Israel, and Luxembourg were the most variable in the average indicator. The most expressed decrease occurred in Finland (2.9 times). The number of PCI has increased significantly (in 9 countries by more than 2 times). The exception was the United States, where the number of PCI decreased by 2 times from 2003 to 2016. In Russia, there was an increase in CABG and PCI (by 10.2 and 50.5 times, respectively). The number of CABG and PCI per 100,000 population was 23 and 34 times less, respectively, in Russia than the international average in 2000, and 1.4 and 1.55 times less in 2018. The decrease in CABG is due to the improvement of PCI technologies, as well as the improvement of pharmaceutical treatment of coronary vessels. The number of proceedings, including court ones, on the validity of stent implantation is growing. The crosscountry variability of the use of cardiac surgical methods is influenced by the organizational and financial characteristics of the healthcare system, demographic and clinical characteristics of patients, the knowledge of doctors, etc. The experience of Russia fully confirms this.Conclusion. There is no optimal method for accurately assessing the population's need for certain treatment methods. Each country chooses its own tactics, taking into account its resource capabilities, approaches to decision-making, its values and preferences, but the general trend is a decrease in the number of CABG operations while increasing the PCI. In Russia, there is a multiple increase in the number of CABG and PCI, but it is less than the indicators of most countries.
