• Muscular dystrophy: It causes weakness, breakdown, and loss of skeletal muscle functions.
• Rhabdomyolis: A rapid breakdown of muscle tissues caused by serious injury, muscle disease, or other diseases.
• Heart attack
• Heart damages

• Dark urine

Creatine kinase (CK), also known as creatine phosphokinase (CPK) or phosphocreatine kinase, is an enzyme That is present in the heart, skeletal muscle, and a small amount in the brain. When the cells in the skeletal muscles, heart muscles, or brain are damaged, they release CK into the blood. (2^✔ ✔Trusted Source
About Creatine Kinase (CK)

There are three types of CK enzymes:

• CK-MM – Found mostly in skeletal muscles
• CK-MB – Found mostly in heart muscle
• CK-BB – Found mostly in brain tissue

The reference range of CK is 22-334 IU/L for men and 22-199 IU/L for women. It may vary from laboratory to laboratory. (3^✔ ✔Trusted Source

• Higher than normal CK-MM enzymes: It may mean you have muscular dystrophy or rhabdomyolis
• Higher than normal CK-MB enzymes: It may mean you have heart muscle inflammation or are having a heart attack
• Higher than normal CK-BB enzymes: It may mean you have had a stroke or brain injury

Other conditions which causes higher CK level may include, (1^✔ ✔Trusted Source
