[The importance of modern high - sensitivity troponin tests in the diagnosis of myocardial infarction without ST-segment elevation].

The literature review presents the characteristics of modern high - sensitivity tests for detection of Tn (hs - cTn) in the blood and the results of large studies on the diagnosis of non segment elevation myocardial infarction (nonSTEMI) using hs - cTn. The results of these studies served as the basis for the development of three - and one - hour diagnostic algorithms nonSTEMI, presented in the recommendations of the European Society of Cardiology 2012 and 2015 and also in fourth Universal Definition of Myocardial Infarction 2018.
