The Compare-Acute trial of fractional flow reserve-guided multivessel angioplasty in myocardial infarction.

The Compare-Acute trial demonstrates the relative safety and utility of performing multivessel FFR to examine the significance of non-culprit lesions during primary PCI. Patients who had an FFR-guided PCI strategy for non-culprit lesions during the index hospitalisation had fewer adverse cardiovascular events, essentially unplanned revascularisations, as compared to patients who were treated for the infarct-related artery only.
