Endo Epa Ethyl Ester Statin Patients Tg 150 499

Adding EPA ethyl ester for statin-treated patients with moderate hypertriglyceridemia

STEP 1 — Gather Information

Confirm the patient is on a statin, obtain a fasting triglyceride level, and assess for atherosclerotic cardiovascular disease (ASCVD) or type 2 diabetes plus ≥2 additional risk factors (e.g., hypertension, low HDL, smoking, family history of premature ASCVD, chronic kidney disease, metabolic syndrome).

STEP 2 — Rule In / Rule Out

Is the triglyceride level >150 mg/dL and ≤499 mg/dL? If yes, proceed to STEP 3; if no, do not add EPA ethyl ester (consider other triglyceride‑lowering strategies).

STEP 3 — Classify or Stratify

Does the patient have ASCVD or type 2 diabetes plus ≥2 risk factors? If yes, classify as a candidate for EPA ethyl ester; if no, do not add EPA ethyl ester.

STEP 4 — Decide

Prescribe eicosapentaenoic acid ethyl ester 4 g/day.

Clinical Guardrails / Mimics / Pitfalls

Do not use EPA ethyl ester if triglycerides are >500 mg/dL (consider fibrates or other agents); monitor for increased atrial fibrillation and bleeding events noted in REDUCE‑IT; if EPA ethyl ester is unavailable or inaccessible, a fibrate such as fenofibrate may be considered; benefit is independent of triglyceride reduction, so do not withhold based on on‑treatment TG levels.

Concrete Clinical Example

A 58‑year‑old man on atorvastatin 40 mg daily presents with fasting TG 210 mg/dL, a prior myocardial infarction (ASCVD), and hypertension. He meets criteria for EPA ethyl ester; prescribe 4 g/day.
