Washington: Omega-3 fatty acids found in certain foods, such as fish oil, may help lower risk of sudden cardiac death in people undergoing hemodialysis, according to a new study.Medical literature long has touted the benefits of omega-3 fatty acids for the heart. But until now, researchers have not studied the potential benefit for people on hemodialysis, who are among the highest-risk patients for sudden cardiac death.The study, which included 100 patients who died of sudden cardiac death during their first year of hemodialysis and 300 patients who survived, is the first to examine this question.Allon N. Friedman, M.D., associate professor of medicine in the Division of Nephrology at the Indiana University School of Medicine and first author of the study, said the findings are impressive enough that he believes a placebo-controlled clinical study is warranted to confirm the results."We found that higher levels of omega-3 fatty acids in the blood of patients who were just starting hemodialysis were very strongly associated with a lower risk of sudden cardiac death over the first year of their treatment," Friedman said.
