It sometimes is difficult to detect myocardial injury in the postoperative patient. The diagnosis is based on the clinical judgment of the examiner plus his interpretation of ancillary aids, including the electrocardiogram and serum glutamic oxaloacetic transaminase (SGOT) values. The usefulness of the SGOT determination during the postoperative period has been questioned in a few instances in which increased values were found despite a clinical opinion that no myocardial damage was present. In order to define more clearly the reliability of the SGOT value in the postoperative period, it was decided to do preoperative and postoperative SGOT determinations in a series of patients undergoing prostatic resection.
This study was prompted by two questions. First, what is the practical value of performing an SGOT determination during the immediate postoperative period on a patient in whom possible myocardial infarction is suspected? Very often the internist is asked to evaluate such a patient
