How do you test for cardiac enzymes? Is it a blood test?

Myocardial enzymes are generally detected by blood test. Myocardial

enzymes are a general term for a variety of enzymes present in the myocardium. They are mainly detected by taking venous blood to extract serum. The tests usually include lactate dehydrogenase, creatine kinase isoenzyme, aspartate aminotransferase, etc. When the myocardium is damaged or necrotic, it can cause myocardial enzymes to be released into the blood, increasing the myocardial enzyme content in the blood.

If the patient has chest tightness, shortness of breath, precordial pain and other symptoms, the level of myocardial enzymes in the blood can be detected to determine whether the myocardium is damaged.
