* * Lecture Notes * Cardiac biomarkers in ST-elevation myocardial infarction (STEMI).Typical cardiac biomarkers that are used to evaluate patients with STEMI include the MB isoenzyme of CK (CK-MB) and cardiac specific troponins. The horizontal line depicts the upper reference limit (URL) for the cardiac biomarker in the clinical chemistry laboratory. The URL is that value representing the 99th percentile of a reference control group without STEMI. The kinetics of release of CK-MB and cardiac troponin in patients who do not undergo reperfusion are shown in the solid green and red curves as multiples of the URL. Note that when patients with STEMI undergo reperfusion, as depicted in the dashed green and red curves, the cardiac biomarkers are detected sooner, rise to a higher peak value, but decline more rapidly, resulting in a smaller area under the curve and limitation of infarct size.
