Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): The reported study was funded by RFBR, project number №19-315-90106 Aim To compare indicators of blood prothrombotic activity in patients with myocardial infarction with and without coronary arteries obstruction Material and methods. The study included 40 patients with AMI (19 patients in the main group and 21 patients in the control group). Three patients (15.7%) with acute myocarditis were excluded from the analysis. Hemostasiological and hematological blood tests were studied upon admission, on the 2nd, 4th, 7th days from hospitalization. Blood samples for protein C, antithrombin, von Willebrand factor (WF), plasminogen, homocysteine were performed on 4th ± 1 day from hospitalization. To determine the IgG / IgM antibodies to cardiolipin and β2-glycoprotein for the diagnosis of APS, the ORGENTEC Anti-β2-Glycoprotein I IgG / IgM ELISA enzyme immunoassay was used. Blood tests for lupus anticoagulant were performed using an ACL-Top 700 analyzer (Werfen) with HemosIL SynthASil dRVVT screen reagents / dRVVT confirm  and with a SCT screen / SCT confirm quartz activator. Results In patients with MINOCA a statistically higher level of homocysteine (p = 0.03) and a lower level of plasminogen (p = 0.007) are determined. Protein C, antithrombin, WF the presence of lupus anticoagulant, antibodies to cardiolipin and β2-glycoprotein no differences between the groups were detected, p &amp;gt;0.05. MINOCA patients have a statistically higher platelet level on the 2nd and 4th day of AMI (p = 0.046 and p = 0.01 ) however the level of hemoglobin and hematocrit was statistically lower on the 4th day of AMI, (p = 0.008). In the main group, a moderate correlation was found between protein C and antithrombin (r = 0.65, p = 0.0001), antithrombin and von Willebrand factor (r = 0.54, p = 0.0001), between protein C and platelet level by 4th day (r = - 0.49, p = 0.04). In MINOCA patients a moderate negative correlation was found between homocysteine and plasminogen (r = -0.69, p = 0.002). In the control group, a high correlation was found between protein C and antithrombin (r = 0.96, p = 0.0001), a moderate correlation between protein C and plasminogen (r = 0.47, p = 0.03). In addition, a relationship was revealed between the presence of thrombosis according to ICAG data and the level of ejection fraction (r = 0.46, p = 0.04) in the control group, as well as between the presence of thrombosis and the level of fibrinogen upon admission (r = 0.55, p = 0.008). Conclusions Patients with MINOCA have a higher level of homocysteine and a lower level of plasminogen. For such indicators as protein C, antithrombin III, WF the presence of antibodies on the APS is not defined differences between groups. According to laboratory data patients with MINOCA showed higher levels of platelets but lower levels of hemoglobin and hematocrit in the early post-infarction period.
