In the current study, Doctor Thomas Rix and colleagues from Aalborg University Hospital in Denmark, set out to examine the hypothesis that a negative association exists between the development of AF and consumption of n-3 PUFA. “Since AF is present in over six million people in Europe and associated with considerable morbidity, mortality and economic costs, preventing AF by achievable dietary changes would be of major public interest,” said Dr. Rix.
“The 13% observed lower risk of AF seen at moderate intakes of marine n-3 PUFA compared with low intakes may be related to a reduction in ischemic heart disease and anti-inflammatory effects in addition to direct anti arrhythmic effects,” said Dr. Rix. He noted that in one study, treatment with 1.8g n-3PUFA/day in patients with low intakes of fish resulted in prolongation of the atrial effective refractory period and less inducible AF, both in subjects with AF (8) and subjects without AF (10).
