Aims  The aim of this study was to determine the contemporary use of reperfusion therapy in the European Society of Cardiology (ESC) member and affiliated countries and adherence to ESC clinical practice guidelines in patients with ST-elevation myocardial infarction (STEMI). Methods and results  Prospective cohort (EURObservational Research Programme STEMI Registry) of hospitalized STEMI patients with symptom onset <24 h in 196 centres across 29 countries. A total of 11 462 patients were enrolled, for whom primary percutaneous coronary intervention (PCI) (total cohort frequency: 72.2%, country frequency range 0–100%), fibrinolysis (18.8%; 0–100%), and no reperfusion therapy (9.0%; 0–75%) were performed. Corresponding in-hospital mortality rates from any cause were 3.1%, 4.4%, and 14.1% and overall mortality was 4.4% (country range 2.5–5.9%). Achievement of quality indicators for reperfusion was reported for 92.7% (region range 84.8–97.5%) for the performance of reperfusion therapy of all patients with STEMI <12 h and 54.4% (region range 37.1–70.1%) for timely reperfusion. Conclusions  The use of reperfusion therapy for STEMI in the ESC member and affiliated countries was high. Primary PCI was the most frequently used treatment and associated total in-hospital mortality was below 5%. However, there was geographic variation in the use of primary PCI, which was associated with differences in in-hospital mortality.

Russian phlebology, as a field of surgery, has passed a long historical path of formation. A.A. Troyanov and his followers laid the foundation for the scientific study of venous pathology. Subsequent works in this area of prominent Russian surgeons made it possible to form those fundamental ideas that are currently the basis of medical tactics. The article presented historical portraits of surgeons of the St. Petersburg phlebology school, who had made a huge contribution to the development of phlebology and the study of surgical pathology of veins.The authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.

The aim of this study was to summarize, systematize, and extend analysis of data of two-year clinical use of intracardiac ECG (ECG-CS) in patients with coronary artery disease.Material and methods. 131 patients with coronary artery disease who underwent a planned coronary stenting were included in a prospective study from 2018 till 2020 . Ischemia was monitored with the use of electrophysiological recording system with the following settings: combining electrodes into fi ve cathode-anode pairs with a frequency range of 30–500 Hz, signal cut-off of 1 cm, and an amplitude of 0.3 mV/cm.Results. According to the ROC-analysis, the sensitivity of the ECG-СS method in case of ST segment depression was 79.5%, the specifi city was 100%; with ST segment elevation — 83% with a specifi city of 100%, according to data obtained in 88 patients with single-vessel disease of the coronary arteries (CA). Out of 43 patients with coronary artery disease, compromise of the diagonal branch and signifi cant ischemic dynamics (p < 0.05) in the intracardiac lead CS 3–4 after stent placement in the ADA according to ECG-CS was observed in 11 (25.6%) patients, in 9 (20.9%) of which successful provisional stenting was performed, and 2 (4 .6%) patients required implantation of the second stent.Conclusion. ECG-CS is a promising method for detecting myocardial ischemia in patients with coronary artery disease and allows to optimize intervention in the area of coronary artery bifurcation.
