The CPK-MB (Creatine Kinase-MB) test measures the MB isoenzyme of creatine kinase, which is predominantly found in heart muscle cells. When the heart muscle is damaged—such as during a myocardial infarction (heart attack)—CK-MB is released into the bloodstream. This test helps in diagnosing acute cardiac injury, differentiating cardiac muscle damage from skeletal muscle injury, and monitoring recovery after cardiac events or procedures. It is often used alongside other cardiac markers like troponin for comprehensive evaluation.
