Myocardial biomarkers are biochemical indicators that reflect heart disease and contribute to the early diagnosis, clinical stratification, and prognosis evaluation of myocardial injury, especially acute myocardial infarction caused by coronary heart disease. The commonly used myocardial biomarkers currently include: myocardial injury/myocardial infarction biomarkers (cTn, H-FABP, MYO, CK-MB, etc.), vascular and coagulation system biomarkers (D-Dimer, etc.), and cardiac function biomarkers (NT proBNP, etc.).
