The main goal of this study was to see if fish oil supplementation affected atrial fibrillation incidence after heart surgery. 401 patients who were about to undergo coronary artery bypass graft surgery were randomized to receive 2 grams fish oil (containing 600 mg EPA and 400 mg DHA) or olive oil placebo daily from four days before surgery until discharge. Post-surgery atrial fibrillation incidence (the primary outcome) did not significantly differ between groups, but there was a possible trend toward a significant reduction in the fish oil group (p = 0.07). However, the fish oil group did tend to have shorter atrial fibrillation episodes, spend less time in the ICU post-surgery, and less time in the hospital overall.Funding issues for this study:
