More in Heart Disease. Cardiac enzymes (the old name), or cardiac biomarkers (the new name), are blood tests that are used to detect damage to heart muscle cells. Cardiac biomarkers are proteins from heart muscle cells that have leaked out into the bloodstream after an injury to the cardiac muscle. Creatine kinase and troponin are the two proteins currently measured in biomarker tests.
Aldolase is an enzyme that helps convert glucose into energy. It is found throughout the body but is primarily found in high levels in muscle tissue. Because aldolase levels are elevated in the bloodstream when a person has muscle damage, the aldolase blood test may be ordered to diagnose and monitor certain conditions related to skeletal muscle. It largely has been replaced by other muscle enzyme tests, especially CK (creatine kinase).
