[High-dose Omega-3 for cardiovascular prevention, a bad idea?]

Abstract

Hypertriglyceridemia is a cardiovascular risk factor independent of LDL cholesterol. omega-3 reduce triglycerides levels, but without proven benefit to reduce cardiovascular risk. Recently, two studies on high-dose omega-3 derivatives have shown contradictory results on the risk of cardiovascular events: REDUCE-IT (4 g/day of icosapent ethyl) showed a 25 % reduction; STRENGTH (4 g/day of a mixture of eicosapentaenoic acid and docosahexaenoic acid) showed no effect. An increased risk of atrial fibrillation was observed in both studies. The European 2021 cardiovascular prevention guidelines propose to consider high-dose ethyl icosapent on a case-by-case basis in patients with hypertriglyceridemia.
