Eating fish rich in omega-3-fatty acids may have different effects on the heart’s electrical function, according to a study presented today at HEART RHYTHM 2006, the Heart Rhythm Society’s 27th Annual Scientific Sessions. Although previous studies have found that fish consumption may protect against the development of atrial fibrillation (AF), the most common type of heart rhythm abnormality, a new study found that eating fish more frequently was associated with a higher risk of developing atrial fibrillation among healthy male physicians. After adjustment for multiple risk factors for AF, lifestyle factors, and other dietary factors, men who ate fish more than five times a week were at a 61 percent increased risk of developing AF as compared to men who ate fish once a month.
