WebThe CK-MB normal range for adults is 24U/L, and the CK value is >190 U/L (men) and >167U/L (women). If someone is suffering from myocardial infarction, the CK-MB activity is in a range of 6-25% of the CK (total) activity. The heart is said to be damaged if the ratio of CK-MB total CK >2.5-3. Web20 de dez. de 2024 · CK-MB activity is normal in 25 - 50% of patients with MI at time of admission (Emerg Med Clin North Am 2001;19:321), rises some 4 - 6 hours after the onset of chest pain, peaks within 12 - 24 hours, and returns to baseline levels within 36 - 48 hours These times may be shorted considerably by thrombolytic therapy.
