Abstract

In patients with dyslipidemia, elevated triglyceride (TG) levels, or TG-rich lipoproteins, and cardiovascular risk may remain despite statin therapy. Prescription omega-3 fatty acid formulations containing the ethyl esters of eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) (omega-3-acid ethyl esters; Lovaza®) or high-purity EPA ethyl ester (icosapent ethyl; Vascepa®) are TG-lowering treatments that may be administered in addition to statins. Here we describe the effects of switching from omega-3-acid ethyl esters to icosapent ethyl in a 44-year-old obese man with dyslipidemia, hypertension, and hypothyroidism. The patient was receiving stable treatment with medications, including atorvastatin 40 mg/day and extended-release niacin 1000 mg/day. Owing to persistently elevated TG levels and other cardiovascular risk factors, the patient was initiated on omega-3-acid ethyl esters 4 g/day. After approximately 2 years on omega-3-acid ethyl esters, his total cholesterol (TC) level was 184 mg/dL, low-density lipoprotein cholesterol (LDL-C) level was 81 mg/dL, TG level was elevated at 307 mg/dL despite statin therapy, and non-high-density lipoprotein cholesterol (non-HDL-C) level was 144 mg/dL. After the switch to icosapent ethyl, TC level decreased by 34% to 121 mg/dL, LDL-C level decreased by 28% to 58 mg/dL, TG level decreased by 41% to 180 mg/dL, and non-HDL-C level decreased by 44% to 81 mg/dL. Switching from omega-3-acid ethyl esters containing both EPA and DHA to icosapent ethyl containing high-purity EPA resulted in beneficial and substantial changes in the lipid profile with a notable reduction of TG levels along with additional reductions in LDL-C levels in a statin-treated obese patient with persistently high TG levels. Treatment with icosapent ethyl was well tolerated.
