| Additional Information | CARDIAC: In MI CK starts to rise 4 - 8 hours post chest pain and peaks at about 24 hrs. It is unreliable 3 days post pain. The CK-MB fraction may be useful to establish the source of a raised CK. Myocarditis can give a similar enzyme picture to MI. MUSCLE: The largest rises occur in association with Duchenne Muscular dystrophy and acute polymyositis. Muscle trauma e.g fitting, falls in the elderly, IM injections, severe exercise also gice rise to raised CK. Other causes of raised CK includedDrugs/toxic substances (steroids, clofibrate, alcohol, CO poisoning), inflammation (myositis), McArdle's syndrome (during exercise) hypothermia, and malignant hyperpyrexia. |
