ACC.24 — Investigator, Dr Felix Böhm (Danderyd Hospital, SE) joins us to discuss the findings from a study investigating fractional flow reserve-guided complete or culprit-only percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (MI).

1542 patients were enrolled in the trial, who were randomized 1:1 to receive either FFR-guided PCI of non-culprit lesions during index hospitalisation, or initial conservative management of non-culprit lesions. The primary endpoint was a composite of death, MI or unplanned revascularization.

Findings suggest that when compared to culprit-lesion-only PCI, FFR-guided complete non-culprit revascularization did not reduce death, MI or unplanned revascularization (HR 0.93; p=0.53). There was an observed benefit to reducing any revascularization, both planned and unplanned, however there was a higher incidence of stent thrombosis via the complete strategy. No differences in stroke, bleeding, heart failure or acute kidney injury were apparent.
