WASHINGTON--Fish oil can help reduce deaths from heart disease, according to new evidence reports released by the Agency for Healthcare Research and Quality (AHRQ), an arm of the Department of Health and Human Services (HHS). AHRQ released three reports on omega-3 essential fatty acids (EFAs) and cardiovascular function; the reports were prepared by the Tufts-New England Medical Center in Boston. The reviewers concluded long chain polyunsaturated fatty acids (LC-PUFAs) reduce heart attack, reduce triglyceride levels, slightly lower high blood pressure, reduce arrthymia and reduce risk of coronary artery re-blockage after angioplasty.
