CardioNerds Tommy Das (Program Director of the CardioNerds Academy and cardiology fellow at Cleveland Clinic), Rick Ferraro (cardiology fellow at the Johns Hopkins Hospital), and Dr. Aliza Hussain (cardiology fellow at Baylor College Medicine) take a deep dive on the REDUCE-IT trial with Dr. Peter Toth, director of preventive cardiology at the CGH medical center in Sterling, Illinois, clinical professor in family and community medicine at the University of Illinois School of Medicine, and past president of the National Lipid Association and the American Board of Clinical Lipidology. Special introduction to CardioNerds Clinical Trialist Dr. Jeff Wang (Emory University). Audio editing by CardioNerds academy intern, Shivani Reddy. This episode is part of the CardioNerds Lipids Series which is a comprehensive series lead by co-chairs Dr. Rick Ferraro and Dr. Tommy Das and is developed in collaboration with the American Society For Preventive Cardiology (ASPC).

Pearls - REDUCE-IT The Reduction of Cardiovascular Events with EPA-Intervention Trial (REDUCE-IT) trial was a large randomized controlled trial that showed a significant reduction in atherosclerotic cardiovascular disease (ASCVD) events with use of icosapent ethyl ester in secondary prevention patients and high risk primary prevention patients with diabetes and residual elevated triglycerides between 135 to 499 mg/dL on top of maximally tolerated statin therapy1. Despite the use of high intensity statin therapy, considerable residual risk for future atherosclerotic cardiovascular disease exists in patients with ASCVD.Elevated triglycerides (TGs) are an important marker of increased residual ASCVD risk2.There are two primary types of Omega-3 fish oils: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Omege-3 fish oils have been shown to lower triglyceride levels.Low-dose combination EPA and DHA has not exhibited incremental cardiovascular benefit in either primary prevention and secondary prevention patients on top of statin therapy3-5.REDUCE-IT showed the use of high dose EPA in patients with either ASCVD or DM and one additional risk factor, and relatively well-controlled LDL-C levels on maximally tolerated statin therapy and residual hypertriglyceridemia (TG 135-499 mg/dL) results in significant reductions in cardiovascular events over a median follow-up period of 4.9 years1. Show notes - REDUCE-IT Multiple epidemiologic and Mendelian randomization studies have established elevated triglyceride (TG) levels as an important risk factor for atherosclerotic cardiovascular events6-8. However previous clinical trials using TG-lowering medication such as niacin, fibrates and low dose omega-3 fish oil have not shown to reduce cardiovascular events when added to statin therapy in patients with or without ASCVD,9,10.The JELIS trial first demonstrated a significant reduction in cardiovascular events when 1.8g daily of eicosapentaenoic acid (EPA) was added to low-intensity statin therapy in patients with ASCVD and hypercholesterolemia, However, the trial was limited due to open label design without placebo, use of low doses of background statin therapy, and geographic/demographic limitations to participants in Japan11.In a large international multicenter randomized controlled trial, the Reduction of Cardiovascular Events with Icosapent Ethyl–Intervention Trial (REDUCE-IT) randomized 8,179 patients with established atherosclerotic heart disease or diabetes and an additional risk factor, on maximally tolerated statin therapy, to 4 gm/day of icosapent ethyl (a highly purified and stable EPA ethyl ester) or miner...
