Detailed Description:

This study aimed to compare the effect of grape seed extract and ascorbic acid in oxidative stress induced by on pump coronary artery by pass grafting surgery.

There are three groups in the study. 75 candidate of coronary artery by pass grafting surgery were assigned random allocation on the groups (25 in each group).

  1. Control
  2. GSE (100 mg/6h - PO, 24h before surgery)
  3. Vit C (25 mg/kg in pump circulation during surgery)
