n-3 polyunsaturated fatty acids after coronary artery bypass grafting.

Background: Despite the robust evidence of the potential benefits of n-3 polyunsaturated fatty acid (PUFA) supplementation in patients with established coronary artery disease, the impact of this therapy on patients after coronary artery bypass grafting remains completely unknown.

Methods: Among 2,100 patients undergoing isolated coronary artery bypass grafting in one tertiary care institution, 930 (44%) were put under n-3 PUFA therapy chronically at discharge. The impact of n-3 PUFAs was assessed by means of propensity-score adjusted analysis.
