Creatine kinase is an enzyme which is produced by the majority of muscle cells.
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.
