Creatinine Phosphokinase (CPK)

Creatinine phosphokinase (CPK), also known as creatine kinase (CK), is an enzyme found mainly in the heart, brain, and muscles. It helps convert creatine, a molecule that provides energy for muscle contractions. When muscles are damaged, CPK levels rise in the blood, indicating potential issues like a heart attack, muscle injury, or certain diseases. Doctors often measure CPK levels to assess muscle health or diagnose conditions involving muscle damage. Understanding CPK levels can provide important insights into a person's overall health or the presence of specific medical issues.
