Aim. To analyze the frequency, indications, and outcomes of using glycoprotein IIb/IIIa inhibitors in patients with acute myocardial infarction (AMI) in Russia based on data from a multicenter registry.Material and methods. This work is part of the REGION-MI (Russian Registry of Acute Myocardial Infarction) multicenter retrospective-prospective observational study, which included patients admitted to hospitals in 45 regions of Russia with a diagnosis of AMI from 2020 to 2023. The decision to prescribe glycoprotein IIb/IIIa inhibitors was made by physicians. The observation period was 12 months, the following outcomes were recorded: cardiovascular events (relapse/repeated AMI, stent thrombosis, revascularisation), hemorrhagic complications, and in-hospital and all-cause mortality during the entire observation period. The study is conducted on the "Quinta" platform. Statistical data processing was performed using IBM SPSS Statistics ver.24.Results. A total of 10,884 patients were included in the registry, glycoprotein IIb/IIIa inhibitors were prescribed to 114 patients (1%), all of whom underwent percutaneous coronary intervention (PCI), while among patients with non-ST elevation myocardial infarction, the frequency of IIb/IIIa inhibitors was 0.5%, among ST-segment elevation myocardial infarction patients — 1.3%. Eptifibatide was used most often (67.5%), tirofiban was prescribed in 28.9% of cases, abciximab — 2.6%, framon — 0.9%. The most common indication for prescribing drugs were complications of PCI, in particular — distal embolism. There was a higher incidence of cardiogenic shock and multivessel revascularization in the glycoprotein IIb/IIIa inhibitor group. In-hospital mortality and adverse events within 180 days (death, cardiovascular events) did not differ between patients who did and did not receive glycoprotein IIb/IIIa inhibitors. The use of glycoprotein IIb/IIIa inhibitors in this study was associated with an increased risk of all in-hospital bleeding (odds ratio 9.656, confidence interval 2.859-3,894, p

Aim. To study the effectiveness of Fortelyzin® in subgroups with different body weights in patients with ST-segment elevation acute myocardial infarction (STEMI) in the FRIDOM1 study and real clinical practice.Material and methods. Fortelyzin® was administered in a single-bolus dose of 15 mg over 10 seconds, regardless of the body weight of patients. Metalyse® was administered in a single-bolus dose of 30-50 mg over 10 seconds, depending on body weight. The one-year results of the FRIDOM1 study were evaluated by the clinical centers using telephone contact. Monitoring of Fortelyzin® use was carried out by inpatient physicians, emergency doctors and paramedics by filling out a monitoring sheet in the period from June 2013 to December 2021 in 19243 patients with STEMI.Results. In the FRIDOM1 study, the distribution of patients depending on body weight in the Fortelyzin® (n=190) and Metalyse® (n=191) drug groups was as follows: up to 60 kg — 4 people each (p=1,00); from 60 to 70 kg — 21 and 23 (p=0,87); from 70 to 80 kg — 39 and 43 (p=0,71), from 80 to 90 kg — 63 and 47 (p=0,07); from 90 to 100 kg — 30 and 41 (p=0,19); over 100 kg — 33 people (p=1,00) in each group. The effectiveness of thrombolysis according to electrocardiographic (ECG) data in the Fortelyzin® and Metalyse® groups was as follows: up to 60 kg — 75% each (p=1,00); from 60 to 70 kg — 76% vs 83% (p=0,72); from 70 to 80 kg — 82% vs 86% (p=0,76); from 80 to 90 kg — 81% vs 77% (p=0,64); from 90 to 100 kg — 80% vs 81% (p=1,00); over 100 kg — 79% vs 76% (p=1,00); in total — 80% vs 80% (p=0,87). The effectiveness of thrombolysis according to coronary angiography (CAG) (TIMI 2-3) in the Fortelyzin® and Metalyse® groups was as follows: up to 60 kg — 100% vs 50% (p=0,43); from 60 to 70 kg — 81% vs 67% (p=0,48); from 70 to 80 kg — 74% vs 84% (p=0,41); from 80 to 90 kg — 70% vs 72% (p=1,00); from 90 to 100 kg — 67% vs 66% (p=1,00); over 100 kg — 58% vs 64% (p=0,80); in total — 70% vs 71% (p=0,76). The one-year survival rate in the FRIDOM1 study in the Fortelyzin® and Metalyse® groups was 94% (p=0,91). The administration of Fortelyzin® in patients with STEMI caused blood flow restoration according to ECG data in 14624 of 19243 patients (76%), while according to CAG (TIMI 2-3) — in 3422 of 4805 patients (71%). Inhospital mortality was 5% (n=962), while intracranial hemorrhage developed in 0,5% (n=92).Conclusion. The use of Fortelyzin® in the FRIDOM1 study and in real clinical practice in a single-bolus (10 sec) dose of 15 mg in patients with STEMI with any body weight showed its high efficacy and safety, including at the prehospital stage.

Aim. To study the results of thrombolytic therapy and accuracy of electrocardiographic assessment of thrombolysis efficiency in inferior myocardial infarction with and without right ventricular lesion.Material and methods. The118 patients with inferior myocardial infarction were included in this study. They received TLT in the first 12 hours of the disease. The dynamics of ST-segment in 90 minutes from the TLT start and coronary angiography data were analyzed.Results. Right ventricular myocardial infarction (RVMI) was diagnosed in 49 (41.5%) of 118 patients by echocardiography. Patients with and without RVMI did not differ in age, gender and comorbidities, but patients with RVMI were more likely to have arterial hypotension, atrioventricular block, and atrial fibrillation. All patients with RVMI had occlusion of the right coronary artery (RCA) in the proximal (34.7%) or medial segment (65.3%). Occlusion of the circumflex coronary artery was found in 20 (29.0%) patients without RVMI, and RCA occlusion - in other patients. The infarction-associated artery blood flow equal TIMI 2-3 was found in 17 (34.7%) patients with RVMI and in 46 (66.7%) patients without RVMI (p0.05). The false-positive assessment of thrombolysis efficiency was noted in patients with and without RVMI in 21 (42.9%) and 11 (15.9%) cases (p

Aim. Evaluate the one­year results and clinical outcomes of a multi­center randomized clinical trial FRIDOM1.Material and methods. The study FRIDOM1 was conducted in 11 clinical centers of the Russian Federation in the period 2014­2016. The study included 382 patients with acute ST­elevated myocardial infarction (STEMI), who were randomly divided into the Fortelyzin® and Metalyse®. Thrombolysis was accompanied by anticoagulant and dual antiplatelet therapy followed by percutaneous coronary intervention (PCI). One­year patient status, all­cause mortality, including cardiovascular diseases (CVD), hospitalization, and one­year survival were assessed by telephone contact.Results. The one­year patient status was determined in 186 out of 191 (97,4%) in the Fortelyzin® group and in 185 out of 191 (96,9%) patients in the Metalyse® group. One­year all­cause mortality was 5,9% and 6,5% in the Fortelyzin® and Metalyse® groups, respectively (p=0,83; OR 0,91; 95% CI — 0,42­1,98). One­year mortality from CVD in the Fortelyzin® group is 5,4%, in the Metalyse® group — 6,5% (p=0,67; OR 0,83; 95% CI — 0,37­1,83). All­cause mortality between 30 days and 1 year in the Fortelyzin® group was in 2,2% of patients, CVD — in 1,6%, in the group of Metalise® mortality was in 2,7% of patients (all — CVD). One­year survival was 94,1% and 93,5% in the Fortelyzin® and Metalyse® groups, respectively.Conclusion. The one­year results of the FRIDOM1 study showed the efficacy and safety of a single bolus administration of Fortelyzin® as part of a pharmaco­invasive strategy for treating patients with STEMI, as well as clinical outcomes that are comparable with Metalyse®, including high survival rates and low CVD mortality.

Aim. To study the prospects of using parameters of right ventricle (RV) longitudinal strain (LS) during systole for the differential diagnosis of RV myocardial infarction (RVMI) and pulmonary embolism (PE).Material and methods. The study included 83 patients who were hospitalized with RVMI or PE in the period from December 2017 to May 2019. The study of RV LS using the two-dimensional speckle-tracking echocardiography was carried out in 30 patients with RVMI (group 1), 15 patients with high-risk PE (group 2), and 38 patients with intermediate-risk PE (group 3).Results. The mean values of RV global LS in patients of groups 1 and 2 did not differ (12,8±2,69 and 12,0±2,56%, respectively) and were significantly lower than in patients of group 3 (15,9±3,03%). The ratio of the interventricular septum (IVS) LS to the RV free wall (FW) LS in the group 1 (1,04±0,43) was significantly lower than in the groups 2 (1,61±0,52) and 3 (1,29±0,38). The ratio of the LS of the RVFW basal segment to the apical segment in group 1 (0,60±0,37) was also significantly lower than in groups 2 (1,69±1,57) and 3 (1,67±1,33).Conclusion. In patients with RVMI, there is a comparable decrease in the LS of the RVFW and IVS, and the LS of the basal segment decreases to a greater extent than the apical one. In patients with PE, the decrease in the LS of the RVFW is more pronounced than in IVS, and the LS of the apical segment decreases to a greater extent than the basal one. These differences can be used for the differential diagnosis of RVMI and PE.

Aim. To compare the efficacy and safety of thrombolytic therapy with recombinant non-immunogenic staphylokinase and tenecteplase in ST elevation myocardial infarction (STEMI) in real clinical practice.Material and methods. 84 patients with onset of STEMI symptoms up to 12 hours ago were included into the non-experimental study with mixed design. Recombinant non-immunogenic staphylokinase and tenecteplase were used in 38 and 46 patients, respectively. The dynamics of the ST segment on the ECG, angiographic reperfusion criteria were evaluated as well as clinical outcomes – mortality, reinfarction, stroke, bleeding and allergic reactions.Results. The ST-segment resolution by 70% after 180 min was achieved in 66% and 66% of patients in recombinant non-immunogenic staphylokinase group and in tenecteplase group, respectively (p=0.66) as well as antegrade coronary blood flow through the infarct-related artery TIMI II-III in 61% and 67% of patients, respectively (p=0.63). Mortality and the rate of reinfarction, intracranial bleeding, stroke, cardiogenic shock, left ventricle aneurism and thrombosis were similar in both groups. Large bleeding (otherwise intracranial one) and allergic reactions were not registered.Conclusion. In real clinical practice the efficacy and safety of recombinant non-immunogenic staphylokinase and tenecteplase in STEMI are similar.

Aim. To assess the efficacy of thrombolytic Fortelyzin in ST elevation myocardial infarction (STEMI) in real clinical practice.Material and methods. Fortelyzin was administered intravenously to 38 patients with STEMI with follow-up assessment of reperfusion success by ECG and angiographic criteria. Bleedings, anaphylaxis and total mortality were considered.Results. The ST-segment resolution up to 70% in 180 min was reached in 66% of patients and angiographic effect TIMI 2-3 – in 60% of patients. The major bleeding rate was 2.6%, allergic reactions – 0%, total mortality – 10.5%. Unsuccessful reperfusion was observed more frequently in patients with ECG ischemia of grade 3 and with angiographic visualization of the collateral blood flow.Conclusion. The general efficacy of Fortelyzin in real clinical practice was 73%. ECG ischemia of grade 3 and the presence of angiographic collateral blood flow predict unsuccessful reperfusion of the infarct-related artery.
