Cardiospecific troponins are specifically localized in the troponin-tropomyosin complex and the cytoplasm of cardiac myocytes. Cardiospecific troponin molecules are released from cardiac myocytes upon their death (irreversible damage in acute coronary syndrome) or reversible damage to cardiac myocytes, for example, during physical exertion or the influence of stress factors. Modern high-sensitive immunochemical methods for detecting cardiospecific troponins T and I are extremely sensitive to minimal reversible damage to cardiac myocytes. This makes it possible to detect damage to cardiac myocytes in the early stages of the pathogenesis of many extra-cardiac and cardiovascular diseases, including acute coronary syndrome. So, in 2021, the European Society of Cardiology approved diagnostic algorithms for the acute coronary syndrome, which allow the diagnosis of acute coronary syndrome in the first 1-2 hours from the moment of admission of the patient to the emergency department. However, high-sensitive immunochemical methods for detecting cardiospecific troponins T and I may also be sensitive to physiological and biological factors, which are important to consider in order to establish a diagnostic threshold (99 percentile). One of the important biological factors that affect the 99 percentile levels of cardiospecific troponins T and I are sex characteristics. This article examines the mechanisms underlying the development of sex-specific serum levels of cardiospecific troponins T and I and the importance of sexspecific cardiospecific troponin concentrations in diagnosing acute coronary syndrome.

Keywords: Cardiospecific troponins, cardiac myocytes, diagnostic threshold, acute coronary syndrome, chest pain, myocardial infarction.
