Definition


Troponin is a muscular protein responsible for muscle contraction. There are three types of troponin, each performing relatively similar functions. This protein is of particular worth due to its tendency to increase in quantity in the blood in fairly early stages of myocardiac infarction, generally within 6 hours. This occurs because it is released by muscular cells that die due to necrosis of the heart muscle. In this way, if myocardial infarction is suspected, troponin concentration can be analyzed twice at an interval of 6 hours in order to reveal a potential infarction if its concentration value has increased, or outrule it if not. Furthermore, troponin can also increase due to other cardiac conditions.
