The Claim

Daily supplementation with 1 gram of marine omega-3 fatty acids (460 mg EPA and 380 mg DHA) for a median of 5.3 years is associated with a 22% lower risk of percutaneous coronary intervention (PCI) in healthy adults aged 50 and older, with a hazard ratio of 0.78 (95% CI: 0.63–0.95; p=0.01), although this was a secondary, non-pre-specified outcome and may reflect reduced coronary disease progression rather than direct prevention.

In plain English

Taking a daily omega-3 supplement for about five years might lower the chance that healthy adults over 50 will need a heart procedure to open a blocked artery, but it’s not clear if the supplement directly caused this benefit.

What the research says

1 study

  1. Study: Marine Omega-3 Fatty Acids and Prevention of Vascular Disease and Cancer

    This big study found that taking omega-3 fish oil pills daily for over five years didn’t stop heart attacks or cancer overall, but it did lower the number of heart attacks. Since PCI is a procedure used to treat blocked heart arteries, and fewer heart attacks mean less need for those procedures, the pills likely help reduce the need for PCI too.
