Why is this procedure done?
Creatine kinase is a type of protein found in the heart, brain, and other muscles in the body. It is also called CK. It helps muscles to work properly. There are different kinds of CK. The kind that is mostly found in heart muscles is creatine kinase MB. This is also called CK MB. When the heart muscle is damaged, there is more CK MB in the blood. The CK MB starts to rise within 3 to 6 hours after a suspected heart attack begins. Your doctor may order this test: ‚
- To see if you have had a heart attack
- If you have chest pain
- Along with other tests for the heart like myoglobin and troponin. These will give a baseline for how much damage the heart has had.
