title: The MB fraction of creatine phosphokinase. An indicator of myocardial involvement in acute pericarditis.
abstract: An elevated level of the MB fraction of creatine phosphokinase (CPK) with normal serum myoglobin and normal CPK values was found in a case of acute idiopathic pericarditis. The elevated serum CPK-MB isozyme is suggested to be an indicator of myocardial involvement accompanying acute pericarditis. The normal CPK and serum myoglobin values and the pattern of rapid decrease of CPK-MB level ruled out the possibility of acute myocardial infarction.
