Omega-3 Fatty Acids for Prevention of Post-Operative Atrial Fibrillation

Summary

This is a large multi-center study to examine whether peri-operative intake of n-3 polyunsaturated fatty acids (PUFA) will reduce the occurrence of post-operative atrial fibrillation or flutter (AF) in patients undergoing cardiac surgery (CS).
