Troponins

Troponins are proteins found in heart muscle cells that help regulate muscle contraction. When the heart muscle is injured, such as during a heart attack, these proteins are released into the bloodstream. Measuring troponin levels through a blood test helps doctors identify if the heart has been damaged. Elevated troponin levels indicate that heart injury may have occurred, making it a key marker in diagnosing conditions like myocardial infarction. Because troponins are specific to heart tissue, they are reliable indicators of cardiac injury, guiding timely diagnosis and treatment.
