The ongoing evolution of cardiac biomarkers for myocardial infarction

Today the preferred biomarkers used to identify suspected MI are cardiac troponins, which are regulatory proteins found in the heart muscle that can detect injury to the heart. Cardiac troponin I (cTnI) was first described as a biomarker specific for MI in 1987, and troponin T (cTnT) was first described in 1989. It was many years before cardiac troponin (cTn) was incorporated into guidelines and recommendations as a preferred marker for use in the diagnosis of MI.
