}} Medical tests that are often referred to as cardiac enzymes include:

  • GOT(Glutamic Oxaloacetic Transaminase, also called Serum Glutamic Oxaloacetic Transaminase (SGOT), Aspartate transaminase (AST), or aspartate aminotransferase (ASAT)
  • LDH(Lactate dehydrogenase)
  • troponin
  • CK(creatine kinase, also known as phosphocreatine kinase or creatine phosphokinase), CK-MB
  • MBis a non-specific enzyme for diagnosing myocardial infarctionand is used less compared to the other enzymes

Cardiac enzymes are released from heart tissues if cardiac muscles are damaged as a result of AMI (acute myocardial infarction). Depending on the cardiac enzyme, it can take between 2 to 24 hours for the enzyme level to increase in the blood. Additionally, determining the levels of cardiac enzymes in the laboratory - like many other lab measurements - takes substantial time. Cardiac enzymes are therefore not useful in diagnosing a myocardial infarctionin the acute phase. The clinical presentation and results from an ECGare more appropriate in the acute situation.
