Fractional Flow Reserve Guided Immediate Versus Staged Complete Myocardial Revascularization in Patients With ST-segment Elevation Myocardial Infarction With Multivessel Disease (Future Study)

In patients allocated to the immediate complete revascularisation group, PCI of the culprit lesion was attempted first and followed by all other lesions deemed to be clinically significant by the operator during the index procedure.

In the staged complete revascularisation group, only the culprit lesion was treated during the index procedure and PCI of all non-culprit lesions deemed to be clinically significant by the operator was planned at a later stage through an elective re-admission within 15-45 days after randomisation.
