Cardiac Troponin is a protein found in heart muscle cells that plays a crucial role in muscle contraction. It exists in three forms: troponin I, troponin T, and troponin C. When the heart is damaged, such as during a heart attack, these proteins are released into the bloodstream, making them important biomarkers for diagnosing heart conditions. Doctors often measure levels of cardiac troponin in blood tests to assess heart health. Elevated levels indicate potential heart damage, helping healthcare professionals determine the severity of a patient's condition and guide treatment decisions.
