Translations:Omega-3 fatty acid/70/en

Evidence suggests that omega−3 fatty acids modestly lower blood pressure (systolic and diastolic) in people with hypertension and in people with normal blood pressure. Omega−3 fatty acids can also reduce heart rate, an emerging risk factor. Some evidence suggests that people with certain circulatory problems, such as varicose veins, may benefit from the consumption of EPA and DHA, which may stimulate blood circulation and increase the breakdown of fibrin, a protein involved in blood clotting and scar formation. Omega−3 fatty acids reduce blood triglyceride levels, but do not significantly change the level of LDL cholesterol or HDL cholesterol. The American Heart Association position (2011) is that borderline elevated triglycerides, defined as 150–199 mg/dL, can be lowered by 0.5–1.0 grams of EPA and DHA per day; high triglycerides 200–499 mg/dL benefit from 1–2 g/day; and >500 mg/dL be treated under a physician's supervision with 2–4 g/day using a prescription product. In this population, omega−3 fatty acid supplementation decreases the risk of heart disease by about 25%.
