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.
