Fish Intake Associated With a Reduced Progression of Coronary Artery Atherosclerosis

November 2004

"Consumption of fish is associated with a significantly reduced progression of coronary artery atherosclerosis in women with coronary artery disease," according to a study reported in the September issue of the American Journal of Clinical Nutrition.

Scientists noted that higher intakes of fish and omega-3 essential fatty acids "are associated with a reduced risk of cardiovascular events and mortality. However, limited data exist on the effect of fish intake on actual measures of progression of coronary artery atherosclerosis."

The prospective cohort study looked at 229 postmenopausal women who had participated in the Estrogen Replacement and Atherosclerosis trial. Scientists checked coronary artery diameter, the mean percentage of stenosis (narrowing) of the arteries and the development of new coronary lesions.

Scientists found that higher fish consumption decreased the rate at which the arteries narrowed and subjects had fewer coronary lesions in the arteries.
