Final answer:
The CPK elevation with MB enzymes elevated and the EKG ST changes denote a possible myocardial infarction (heart attack).
Step-by-step explanation:
The CPK elevation with MB enzymes elevated and the EKG ST changes denote a possible myocardial infarction (heart attack).
CPK (creatine phosphokinase) is an enzyme that is present in cardiac muscle, skeletal muscle, and the brain. It is used as a marker enzyme for the diagnosis of a heart attack.
EKG (electrocardiogram) is a test that records the electrical activity of the heart. ST changes on an EKG can indicate an acute myocardial infarction.
