What diseases can be detected by measuring cardiac enzymes?

Myocardial enzyme tests can assist in the diagnosis of various diseases, mainly including: 1. **Cardiac diseases**: Such as myocardial infarction, myocarditis, and cardiomyopathy. When myocardial cells are damaged, myocardial enzymes are released into the bloodstream, causing elevated levels of these enzymes. This helps doctors determine whether there is myocardial injury or heart disease. 2. **Non-cardiac diseases**: Elevated myocardial enzymes may also be associated with liver injury, kidney injury, brain injury, etc. For example, patients with viral hepatitis may show increased levels of lactate dehydrogenase (LDH) and aspartate aminotransferase (AST); patients with glomerulonephritis may exhibit elevated lactate dehydrogenase levels. In addition, myocardial enzyme testing can be used to assess the extent of myocardial cell damage, evaluate patient prognosis, and guide clinical medication use and observation of treatment effectiveness.
