Prescription EPA & heart events

Does prescription EPA prevent cardiovascular events?

The question behind the headline

8,179 high-risk adults on statins with elevated triglycerides; 4 g/day icosapent ethyl versus mineral oil.

What the finding does—and doesn’t—tell us

The primary endpoint occurred in 17.2% versus 22.0% over a median 4.9 years. Atrial-fibrillation hospitalization was higher. STRENGTH tested a different formulation and found no primary-endpoint benefit.

Three questions to take forward

  • Was the study population similar to the person or situation I have in mind?
  • Did it measure an outcome people feel or experience, or only a laboratory marker?
  • How do formulation, usual care, absolute benefit and adverse effects change the interpretation?
