What benefit do prescription omega-3 fatty acids have for A fib?

According to a recent American Heart Association clinical trial, prescription omega-3 fatty acids have no significant benefit on treating atrial fibrillation. Study participants taking prescription omega-3 fatty acids had similar symptoms and results as volunteers given a placebo or sugar pill. While eating fish high in omega-3 fatty acids has been shown to reduce the risk of sudden death from heart disease, taking a prescription omega-3 does not appear to prevent or reduce atrial fibrillation symptoms. Researchers concluded that the benefits of taking a prescription omega-3 do not justify the expense of the medication.
