High levels of creatine kinase (CK) can be observed in various medical conditions that involve muscle damage or injury. Some common examples include myocardial infarction (heart attack), muscular dystrophy, rhabdomyolysis (severe muscle breakdown), polymyositis (inflammatory muscle disease), dermatomyositis, and certain metabolic disorders. Additionally, conditions that cause chronic muscle damage, such as prolonged physical exertion, strenuous exercise, or muscle trauma, can also lead to elevated CK levels. It is essential to identify the underlying cause of high CK levels through proper medical evaluation and diagnostic testing to determine the appropriate treatment approach.
