What are cardiac enzymes checked for?

Myocardial enzymes are a general term for a variety of enzymes present in the heart muscle. When the heart muscle is damaged, enzymes are released into the blood. At this time, blood samples will be taken to detect elevated enzymes. Myocardial enzymes include lactate dehydrogenase, creatine phosphokinase, creatine phosphokinase isoenzyme and α-hydroxybutyrate dehydrogenase. Elevated myocardial enzymes are generally seen in myocardial infarction, cardiomyopathy and skeletal muscle damage. If acute myocardial infarction, cardiomyopathy, muscle damage, this time under normal circumstances to check myocardial enzymes.
