Abstract
Cardiac troponins (troponin I, T, and C) play an important role in the regulation of contractile function of the heart muscle. Mutations in cardiac troponins are associated with the development of various types of cardiomyopathies, which lead to heart failure and death. The determination of the concentration of cardiac troponins in the blood is used in the diagnosis of some cardiovascular diseases, including acute myocardial infarction, myocarditis, heart failure. This review summarizes the available data on the structure and functions of cardiac troponins, their role in the regulation of myocardial contractions and clinical application.
