Cardiac biomarkers show up in the blood after a heart has been under severe stress and becomes injured because it isn't getting enough oxygen. The levels of biomarkers are often used to quickly find out the size of a heart attack and how seriously the heart was affected. Cardiac troponin is by far the most commonly used biomarker, which has the highest known sensitivity. It enters into the bloodstream soon after a heart attack and stays in the bloodstream days after all other biomarkers go back to normal levels. CK-MB is a subtype of CK. It is more sensitive for finding heart damage from a heart attack. CK-MB rises 4 to 6 hours after a heart attack but is generally back to normal in a day or two. Myoglobin is a small protein that stores oxygen. Myoglobin is sometimes measured in addition to troponin to help diagnose a heart attack.
