High-dose omega-3 carboxylic acid formulation (4 g/d) does not reduce major adverse cardiovascular events in high-risk patients with atherogenic dyslipidemia compared to corn oil.

For high-risk patients with high triglycerides and low HDL, adding 4g/day of omega-3 carboxylic acid to statin therapy does not reduce the risk of heart attack, stroke, or cardiovascular death compared to a placebo. This specific formulation and dose should not be relied upon for cardiovascular risk reduction in this population.

Among statin-treated patients at high cardiovascular risk, the addition of omega-3 CA, compared with corn oil, to usual background therapies resulted in no significant difference in a composite outcome of major adverse cardiovascular events.
