Cardiac Markers

Cardiac markers are specific substances found in the blood that help doctors determine if the heart has been damaged, such as during a heart attack. When the heart muscle is injured, these markers are released into the bloodstream. Common markers include troponin, creatine kinase (CK), and myoglobin. Measuring their levels helps healthcare providers diagnose acute heart problems quickly and accurately, guiding treatment decisions. Elevated levels usually indicate some degree of heart muscle injury, while normal levels suggest the heart is not currently affected. These tests are essential tools in evaluating chest pain and assessing heart health.
