Indicator dynamics of the “Combating Cardiovascular Diseases” regional program aimed at reducing mortality from acute coronary syndrome

Aim. To analyze the dynamics of the application of medical and organizational technologies for achieving the target reduction of mortality from acute coronary syndrome (ACS) in the region. Materials and methods. In 2018, the research covered 1 regional vascular center (RVC), 8 primary vascular departments (PVD), and 41 medical organizations (MO). In 2022, the structure of medical organizations changed to include 3 RSCs, 9 PSOs, and 39 MOs. The indicators characterizing the provision of medical care to ACS patients in the Irkutsk region were calculated and analyzed. The presence, direction, and strength of correlation between the number of deaths from ACS and the number of medical and organizational activities was studied using linear correlation analysis by the Pearson method. Results. Over time, the share of hospitalization of patients with ACS in the early stages up to 12 hours increased from 42.1% to 46.5%. The mortality rate from ACS decreased by 20.4%, primarily due to a decrease in mortality in the first 24 hours (by 28.7%). The key medical and organizational technologies that have the greatest impact on mortality rates were identified. A strong relationship ( r = -0.729) was established between the number of deaths from ACS and the number of patients transferred to the regional vascular center for emergency coronoplasty; two medium-level relationships ( r = -0.343) were found between the number of deaths from ACS and the number of hospitalized patients with ACS in the first 12 hours; a correlation ( r = -0.415) was determined between the number of deaths from ACS and the number of hospitalized patients who underwent thrombolytic therapy. The linear regression method showed that the availability of such procedures as emergency coronoplasty and thrombolytic therapy has prognostic significance for further reduction of the expected number of deaths from ACS in the region. Conclusion . The creation of the RVC and PVD infrastructure in the region allowed the major indicators of the “Combating Cardiovascular Diseases” regional program to be achieved.
