What are the reference values for cardiac markers?

Myocardial markers

are biochemical indicators used to assess myocardial injury. These markers are released into the blood when myocardial injury occurs, such as acute myocardial infarction. Commonly used myocardial markers include aspartate aminotransferase, creatine kinase, cardiac troponin, etc. The reference ranges of these indicators may vary according to different laboratories, different detection methods, different age, gender and other factors. For example, aspartate aminotransferase is measured by enzyme coupling rate method.
