National Results of Revascularization for Acute Coronary Syndrome in 2023.

Aim    To analyze the results of myocardial revascularization in the Russian Federation (RF) for ACS in 2023 compared to previous years.Material and methods    The analysis included the number of cases of ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation acute coronary syndrome (NSTE-ACS), myocardial revascularization in the above-listed ACS forms, the number of fatal outcomes depending on the ACS form and the revascularization method used. The data for this analysis were obtained from the 2023 Ministry of Health of Russia monitoring in the section of revascularization in ACS and were compared with the data for the past 8 years.

Randomized Clinical Trial of Hybrid vs. Surgical vs. Percutaneous Multivessel Coronary Revascularization: 5‑year Follow-up of HREVS Trial.

Aim      To evaluate 5-year results of the HREVS (Hybrid REvascularization Versus Standarts) study.Material and methods  The study included 155 consecutive patients with multivessel coronary artery disease who were randomized into 3 groups: coronary artery bypass grafting (CABG) (n=50), hybrid coronary revascularization (HCR) (n=52) and percutaneous coronary intervention (PCI) (n=53) according to the consensus of the cardiology team on the technical and clinical feasibility of each of the three coronary revascularization strategies. The primary endpoint of the study was residual ischemia 12 months after revascularization according to data of single-photon emission computed tomography (SPECT).

New Tissue-Engineered Vascular Matrix Based on Regenerated Silk Fibroin: Study.

Unlabelled: was to make a vascular patch based on regenerated silk fibroin (SF) and study its physical and mechanical characteristics, biocompatibility and matrix properties in comparison with polyhydroxybutyrate/valerate/polycaprolactone with incorporated vascular endothelial growth factor (PHBV/PCL/VEGF) and commercial bovine xenopericardium (XP) flap in experiments .

Materials And Methods: Tissue-engineered matrices were produced by electrospinning. The surface structure, physical and mechanical characteristics, hemocompatibility (erythrocyte hemolysis, aggregation, adhesion and activation of platelets after contact with the material) and matrix properties of vascular patches (adhesion, viability, metabolic activity of EA.
