Troponin is a protein complex found in cardiac and skeletal muscle. It consists of three subunits: troponin C, troponin I, and troponin T. When the heart muscle is damaged, troponin is released into the bloodstream. Elevated troponin levels are a critical biomarker for diagnosing myocardial infarction (MI) or heart attack. Nursing professionals must understand the significance of these levels to provide effective patient care.
