Cardiac Troponin I

Cardiac Troponin I is a protein found in heart muscle cells that helps regulate muscle contraction. When the heart muscle is damaged—such as during a heart attack—these cells release Troponin I into the bloodstream. Therefore, measuring Troponin I levels through a blood test can help doctors detect and diagnose heart muscle injury accurately. Elevated Troponin I levels are a key indicator of heart damage, making it an important tool in evaluating patients with symptoms like chest pain. This test helps ensure timely diagnosis and treatment of heart-related conditions.
