An increase in CPK-MB level indicates cellular necrosis of myocardial tissue, which suggests acute myocardial infarction (AMI) or heart attack. This information is crucial to the treatment team, as it guides the appropriate management of the patient's condition, such as administering thrombolytic therapy or other interventions. Lactic acid levels may also be elevated in AMI, but it is not the primary indicator. Cardiac function returning to normal would be a positive development, but an increase in CPK-MB would not be associated with this.
