The cardiac enzyme blood test is useful in measuring the intensity of proteins and enzymes in the blood. This test is also useful in determining the level of damage to heart muscles. This test measures troponin I and troponin T.The enzymes are normally found in the blood.If the heart enzyme test shows a higher concentration of the enzymes then it means that the person has suffered a heart attack.
Normal levels of these proteins could indicate that the person is okay. The rise of their levels in the human body could be an indicator of other conditions such as depression etc.
