ABSTRACT
Background. COVID-19 increases the risk of developing thromboembolic complications, including acute myocardial infarction, in the acute period of the disease. The long-term consequences of COVID-19 are poorly understood. At the same time, the available data on an increased risk of acute coronary syndrome after infectious diseases allow us to make an assumption about a similar risk in COVID-19. The aim of the study was to study the anamnestic and laboratory diagnostic data in patients with acute coronary syndrome after COVID-19. Methods. The study included 185 patients with acute coronary syndrome who were admitted to the State Clinical Hospital No. 13 in Moscow in the period from May to December 2020. 2 groups were identified: group 1 - 109 patients with ACS who had previously suffered COVID-19, group 2 - 76 patients with ACS without COVID-19 in the past. The patients were collected anamnesis, including: the fact of smoking and alcohol consumption, heredity, previous diseases, including diabetes mellitus, acute myocardial infarction, previously performed PCI. Information about the COVID-19 infection has been collected (the duration of the disease, the course of the disease). A clinical and laboratory examination was conducted, including the determination of body mass index (BMI), examination for antibodies to COVID-19, determination of the lipid profile level (total cholesterol, LDL, HDL, triglycerides), blood glucose level, C-RB. The analysis was performed on automatic biochemical analyzers Hitachi-902, 912 (Roche Diagnostics, Japan). All patients underwent coronary angiography. Results. In patients with ACS with previously transferred COVID-19, the development of the disease occurred at a younger age compared to patients without transferred COVID-19. Among the patients with COVID-19, body weight was significantly lower, there were fewer smokers, concomitant type 2 diabetes mellitus and transferred ONMC were less common. In laboratory parameters, lower triglyceride levels were observed in patients with ACS with COVID-19 compared with those of patients without COVID-19. In the laboratory parameters of blood clotting in patients with ACS with COVID-19, higher APTT, thrombin time, fibrinogen level, D-dimer were noted. The indicated laboratory parameters in the groups had statistically significant differences. In ACS patients with a previous COVID-19, compared with patients without COVID-19, the lesion of 2 or more coronary vessels was more common in the anamnesis. Conclusion. According to the results of our study, it was revealed that multivessel coronary artery damage in patients after COVID-19 in comparison with patients without COVID-19 develops significantly more often, while these patients are significantly less likely to have DM and previously suffered ONMC, the level of TG is significantly lower.
