Summary

This prospective, multicenter, open-label, superiority trial will enroll patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease. Following successful percutaneous coronary intervention (PCI) of the infarct-related artery (IRA), patients who meet the eligibility criteria will be randomized in a 1:1 ratio to either in-hospital staged complete revascularization with PCI of non-IRA lesions performed on a separate day during hospitalization, at least 48 hours after PCI of the IRA, or out-of-hospital staged complete revascularization with PCI of non-IRA lesions performed after discharge between 15 and 45 days of randomization. In both groups, non-IRA lesions with 50-69% stenosis will be evaluated using FFR.

Conditions

  • Myocardial Infarction (MI)

Interventions

PROCEDURE

In-hospital staged complete revascularization

PCI of non-IRA lesions will be performed on a separate day during the index hospitalization, at least 48 hours after PCI of the IRA. Non-IRA lesion which have equal or more than 70% diameter stenosis by visual estimation will be revascularized without FFR evaluation. Non-IRA lesion with diameter stenosis 50-69% by visual estimation will be evaluated using FFR device. In case of FFR value more than 0.8, non-IRA lesion will be deferred without PCI. If FFR value was equal or less than 0.8, non-IRA lesion will be revascularized.

PROCEDURE

Out-of-hospital staged complete revascularization

PCI of non-IRA lesions will be performed after discharge and between 15 and 45 days of randomization. Non-IRA lesion which have equal or more than 70% diameter stenosis by visual estimation will be revascularized without FFR evaluation. Non-IRA lesion with diameter stenosis 50-69% by visual estimation will be evaluated using FFR device. In case of FFR value more than 0.8, non-IRA lesion will be deferred without PCI. If FFR value was equal or less than 0.8, non-IRA lesion will be revascularized.
