Cardiac enzyme pentathlon generally refers to myoglobin, creatine kinase, creatine kinase isoenzyme, lactate dehydrogenase, and glutamate aminotransferase. Cardiac enzymes are usually used to check whether there is damage to cardiomyocytes, and generally include myoglobin, creatine kinase, creatine kinase isoenzyme, lactate dehydrogenase and glutamine transaminase. When myocardial infarction, myocarditis and other diseases occur, cardiac enzyme profiles will show different degrees of elevation, which can be combined with electrocardiograms, patient’s symptoms, cardiac imaging and other tests to confirm the diagnosis. Abnormal cardiac enzyme profile does not only mean damage to cardiac muscle cells, but also damage to skeletal muscle cells and liver cells, which can lead to abnormal cardiac enzyme profile, and it is recommended to have a professional doctor to make a judgment to avoid delaying the condition.
