Abstract

The article deals with an important problem of managing patients with myocardial infarction (MI). It’s known that the greatest benefit of immediate invasive intervention obtains patients with acute occlusion of the coronary arteries (or subocclusion). However, numerous studies have shown that up to 30 % of patients classified as non-ST segment elevation myocardial infarction (NSTEMI) are consistently found to have missed acute coronary occlusion. At that time, a number of patients with «benign» ST elevation undergo unnecessary catheterisation +/- reperfusion therapy that increases the risk of complications. In 2018 Meyers P., Weingart S. and Smith S. noted that ST elevation on ECG is most likely an unreliable tool for detecting patients that will benefit from immediate percutaneous coronary intervention (PCI) and that a shift is required to a more reliable paradigm for detecting acute coronary occlusion, than the concept ST-elevation myocardial infarction. The authors introduced us to the new concept of Occlusion Myocardial Infarction (OMI) and Non-Occlusion Myocardial Infarction (NOMI). In this article we discuss five examples of ECG with occlusive myocardial infarction (OMI).
