AbstractAntioxidants may reduce pancreatic cellular injury after coronary artery bypass grafting (CABG) Twenty patients (Group A) received vitamin E (600 mg/ day) for 28 days and vitamin C (2 g/day) and allopurinol (600 mg/day) 2 days before and 1 day after CABG. Seventeen patients (Group C) received all drugs for 3 days, and 25 (Group B) and 19 (Group D) patients served as corresponding controls. The pre- and postoperative pancreatic isoamylase (P-amylase), creatinine, and antioxidant concentrations were measured. Serum hyperamylasemia was highest on the first postoperative day and occurred in 73% of the patients. After surgery serum P-amylase increased in all study groups and urine P-amylase decreased. Postoperative serum hyperamylasemia, whether primarily renal or pancreatic, cannot be decreased by pretreatment with allopurinol, vitamin C, and vitamin E.
