Normal Values and Significance of the Three Cardiac Infarction Markers

Myocardial infarction refers to acute myocardial infarction. The three cardiac markers for acute myocardial infarction include cardiac troponin, myoglobin, and creatine kinase-MB (CK-MB), and their normal values depend on the specific test used. These markers are significant for the early diagnosis of acute myocardial infarction. Detailed analysis is as follows:

1. Normal values of the three cardiac markers for acute myocardial infarction

The three markers consist of cardiac troponin, myoglobin, and creatine kinase-MB. The normal value for cardiac troponin is <0.04 ng/mL; for myoglobin, it is <110 μg/L; and for creatine kinase-MB, it is <5 ng/mL.

2. Clinical significance

If any of these three markers are elevated, it may indicate myocardial injury. The most common causes of myocardial injury are acute myocardial infarction and acute myocarditis. Monitoring these three markers helps in the early diagnosis of conditions such as acute myocardial infarction and acute myocarditis.

If a diagnosis of acute myocardial infarction is confirmed through testing, it is recommended to promptly initiate treatment according to the patient's clinical condition, with a suitable therapeutic plan developed by a physician.
