Outcome of implementation of the project aimed to prevent cardiovascular diseases in the regional vascular center

Highlights. The article presents an analysis of the outcome of the project dedicated to cardiovascular disease prevention in the Regional Vascular Center, the analysis involved the assessment of changes in the characteristics of deceased patients. The study made it possible to identify changes in mortality rate, the impact of new diagnostic and treatment techniques and administrative decisions on the change in mortality, as well as aspects that prevent further reduction in mortality.Aim. To assess the results of the implementation of new methodological approaches to cardiovascular diseases prevention, myocardial infarction in particular, in the Regional Vascular Center.Methods. The study involved the analysis of the data (entered in real time) from the Emergency Cardiac Care Department of the Сardiology Research Institute, Tomsk National Research Medical Center of the Russian Academy of Sciences, and data from the Department`s database containing anamnestic and clinical characteristics of patients, and recording of deaths in the period from 2014 to 2019. Statistical data processing was performed using the StatSoft Statistica software (ver. 10.0).Results. From 2014 to 2019, percutaneous coronary intervention (PCI) in myocardial infarction (MI) increased from 48 to 67.4% (p˂0.05); the primary PCI in MI with ST segment elevation (STEMI) increased from 24% to 32% (p˂0.001), the overall frequency of PCI in STEMI (primary + rescue + delayed) increased from 59.6% to 73% (p˂0.05); PCI in MI without ST segment elevation (NSTEMI) increased from 23.9% to 43.9% (p˂0.001), the frequency of intra-aortic balloon counterpulsation increased from 0.6% to 1.5% (p˂0.05), the frequency of mechanical ventilation did not change (8,3 and 8,5%), moreover the widespread use of ticagrelor and prasugrel was noted. At the same time, hospital mortality of patients with MI decreased from 9.8 to 8.0% (p>0,05): in patients with STEMI it decreased from 10.7% to 7.7% (p = 0.047), in patients with NSTEMI there was no change in mortality, it remained equal to 8–9%. Implementation of coronary reperfusion strategies that do not involve streptokinase is associated with a decrease in hospital mortality of patients with STEMI.Conclusion. The widespread introduction of modern invasive and medicinal technologies has led to a decrease in mortality of patients with STEMI. Further increasing the number of available invasive procedures – PCI, intra-aortic balloon counterpulsation and mechanical ventilation for the purposes of reducing mortality of patients with MI seems questionable.
