[Troponins: new biochemical markers of myocardial damage. Structure, immunoassay and clinical application].

The development of immunoassay techniques has made it possible to use new biochemical markers with a high myocardial specificity. Immunoassays have been developed for two of the structural myocardial proteins: troponin I and troponin T. The authors describe the biochemical properties of the troponins and the available methods of immunoassay. The main clinical applications of troponin measurement in cardiological practice are also reported.
