How Blood Enzyme Tests Relate to Heart Attacks

Blood tests are any easy way for doctors to quickly check a person for a variety of conditions, and they usually don't require more than a few minutes of time. In order to do a blood test, a lab worker may have to use a needle to draw blood from your arm. This blood can also be drawn through a finger prick. There are several different types of blood tests that doctors can request, one of which is a blood enzyme test.

A blood enzyme tests measures the amount of different enzymes in the blood. Enzymes play an important role in the body as they help to control chemical reactions. There are many different blood enzyme tests, but two of the most common tests are a troponin level test and a creatine kinase level test.

Troponin is a muscle protein that aids in muscle contractions. Troponin leaks into the blood stream when muscles or heart cells become damaged. If a patient is having a heart attack, the amount of troponin in their blood will increase. Doctors will often check a patient's troponin level if they are complaining of chest pain or other heart attack symptoms.

Creatine kinase is another chemical that is released when the heart becomes damaged. If a patient's creatine kinase levels are high, it may be a good indication that they have had a heart attack.

There are usually no side effects to having a blood test done other than the potential for slight bruising at the area of the test and a short-lived feeling of dizziness. Patients who have had a large amount of blood drawn need to drink plenty of water and eat as soon as possible.For more information about blood tests: http://www.nhlbi.nih.gov/health/dci/Diseases/bdt/bdt_types.htmlFor more information from the American Heart Association: http://www.americanheart.org/presenter.jhtml?identifier=4726
