Fish oil may not prevent CV problems in people with preexisting heart disease

The Los Angeles Times “Booster Shots” reports, “Omega-3 fatty acids don’t help people with preexisting heart disease avoid future cardiovascular trouble,” according to a study published in the Archives of Internal Medicine.

HealthDay reports that investigators analyzed data from “14 studies that had been published in the medical literature.” Altogether, “the studies looked at more than 20,000 patients who had a history of cardiovascular disease.”

MedPage Today reports that the “data … showed a relative risk of 0.99 for patients treated with omega-3 supplements, virtually identical to the risk in the placebo groups.”

The researchers reported that “a small reduction in cardiovascular death disappeared after exclusion of a trial that had major methodologic problems.”
