The heart, brain and skeletal muscles are the parts of the body that primarily contain the enzyme creatine kinase, states Healthgrades. Increased creatine levels often accompany heart attacks, trauma, stroke, brain injury and conditions that impair the brain or skeletal muscles. CK-MM is a form of creatine kinase found in the heart and skeletal muscles, whereas CK-MB is present in the heart. The type of creatine kinase located in the brain is called CK-BB.

A higher creatine kinase level usually manifests a few hours after a heart attack when the heart muscle cells start to die, says Healthgrades. It continuously increases within 24 hours following a heart attack and goes back to a normal level after several days.

It is essential to contact a doctor immediately if a person experiences severe symptoms such as chest pain, breathing difficulty or paralysis, as these can indicate a heart attack or another fatal condition, notes Healthgrades. Anyone who notices sudden weakness on a single side of the body, a momentary loss of consciousness or vision changes should also seek prompt medical help.
