Omega-3 Fatty Acids: Exploring Cardiovascular Benefits and Clinical Uses

Omega-3 fatty acids are recognized for managing lipids, but their role in cutting cardiovascular risk
continues to be studied.Frank Qian, MD, MPH, a cardiovascular medicine fellow at Boston Medical Centre,
addressed the 2025 National Lipid Association (NLA) Scientific Sessions in Miami, florida, on the topic.

Qian discussed the clinical uses for prescription omega-3s, differences among formulations, and debates
around trial results and placebo effects in heart research.
Prescription omega-3 fatty acids have a couple of indications, Qian said. One is for hypertriglyceridemia,
for which the FDA has approved two strategies.The first uses a mix of eicosapentaenoic acid (EPA) and
docosahexaenoic acid (DHA) at 2 to 4 grams daily, typically for patients with triglyceride levels above 500
mg/dL. The second, for cardiovascular disease risk reduction, uses 4 grams daily of purified EPA-only
icosapent ethyl, for patients with levels of 150 to 499 mg/dL already on statins.
Recent large-scale cardiovascular outcomes trials have focused on higher omega-3 doses, Qian noted. Earlier
trials used lower doses, often mixes of EPA and DHA. The REDUCE-IT trial, using 4 grams of purified EPA
icosapent ethyl, showed a important benefit in reducing cardiovascular events. However, the use of mineral
oil as a placebo raised concerns about potential negative effects on the control group.
Two other major trials, STRENGTH and OMEMI, tested higher doses of omega-3s. The STRENGTH trial used 4 grams
of combined EPA and DHA, while OMEMI used 1.8 grams of a similar combination. Neither trial showed
cardiovascular benefits compared to placebo.
The RESPECT-EPA trial in Japan, a successor to the JELIS trial, tested 1.8 grams of purified EPA. It found a
modest reduction in the primary endpoint,though not statistically significant.However, it did show benefits
in secondary endpoints, especially coronary disease outcomes, similar to REDUCE-IT.
Some experts argue that the totality of data from JELIS, RESPECT-EPA, and REDUCE-IT suggests a real
cardiovascular benefit from purified EPA, Qian said.
qian added that as JELIS and RESPECT-EPA did not use mineral oil as a placebo, their results are less
subject to concerns about potential harms from the mineral oil placebo used in REDUCE-IT.
What’s next
Research continues to clarify the specific benefits of different omega-3 formulations and dosages for
cardiovascular health, with ongoing scrutiny of placebo effects in clinical trials.
