Cardiac enzyme test is a kind of blood test, which can assess the heart-related functions and be one of the auxiliary tests for certain heart diseases. If troponin in cardiac enzyme is elevated, it suggests the possibility of myocardial cell damage, such as clinical common acute myocardial infarction and viral myocarditis, and the magnitude of the elevation is proportional to the severity of the disease. In addition to cardiac diseases that can cause elevated cardiac enzymes, other diseases may also cause elevated cardiac enzymes, such as inflammation, cerebrovascular disease, pulmonary embolism, malignant tumors and other diseases. In addition to disease, oral intake of certain drugs can also cause myocardial enzyme elevation, such as statin drugs lead to rhabdomyolysis, will make myocardial enzyme in the creatine kinase and myoglobin elevated, if myocardial enzyme is normal, basically ruled out the acute heart disease.
