Creatine Phosphokinase-MB (CPK-MB)

The CPK-MB Test measures the levels of Creatine Phosphokinase-MB (CPK-MB), an enzyme found primarily in the heart muscles. It is used to detect heart muscle damage, especially in conditions like heart attacks (myocardial infarction). CPK-MB is released into the bloodstream when heart muscle cells are damaged due to a heart attack, inflammation, or injury.

Why is the CPK-MB Test Important?

• High CPK-MB levels indicate heart muscle damage due to a heart attack, myocarditis, or cardiac surgery.
• This test helps differentiate heart-related pain (cardiac origin) from muscle injuries or other causes of chest pain.
• It is often used along with Troponin tests for a more accurate heart attack diagnosis.

When is the Test Recommended?

• If a person experiences chest pain, shortness of breath, or suspected heart attack symptoms.
• For individuals with a history of heart disease, high blood pressure, or recent cardiac procedures.
