A new study presented Sunday at the American College of Cardiology says fish oil is of no benefit to patients at cardiovascular risk.
The study enrolled more than 10,000 patients, half of whom were taking prescription fish oil and half were taking a corn oil-based placebo.
The results show that patients who took fish oil supplements had no benefit in terms of decreased heart attack or stroke.
According to lead author Dr. Steven Nissen, fish oil seems to significantly increase the risk of atrial fibrillation or irregular heartbeat.
Because of this, he doesn’t think that taking fish oil supplements is a good recommendation for patients at risk for heart disease.
Dr. Nissen calls it “a sad story for cardiology”.
