title: The value of serum magnesium estimations in the diagnosis of acute perioperative myocardial infarction after coronary artery surgery.
abstract: Serum magnesium levels fall significantly after acute myocardial infarction. Even greater decreases have been found in all patients undergoing aorto-coronary bypass surgery. This is probably related to the use of cardiopulmonary bypass. No significant difference in serum magnesium levels was found between those patients who had a well documented peri-operative infarct and those who had an uncomplicated course. Thus determination of serum magnesium levels if of no use in the diagnosis of peri-operative myocardial infarction.
