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.
