Detailed Description
The treatment of choice of ST-segment elevation myocardial infarction (STEMI) is acute reperfusion therapy, preferably with primary percutaneous coronary intervention (PCI). While need of treating the infarct related artery (IRA) is obvious, need for routine revascularization of non-infarct related artery (non-IRA) has been a topic of debate until recent years. Through a number of observational studies, randomized trials and meta-analyses, the benefits of non-IRA PCI have been continuously implied, and COMPLETE trial with 4041 patients of STEMI and multivessel coronary artery disease in 2019 demonstrated superiority of complete revascularization to culprit-only PCI in terms of cardiovascular death or MI (primary end point) and cardiovascular death, MI, or ischemia-driven revascularization (co-primary end point).8 As such, complete revascularization of a significant non-IRA stenosis is recommended after successful primary PCI in STEMI patients in current clinical guidelines.
Nevertheless, it has been unclear which criteria should be used to decide non-IRA PCI. Although potential significance of non-IRA lesions can be estimated by angiography, the limitation of angiographic visual assessment or quantitative coronary angiography has been well known. Various measurements are used for incremental information in addition to angiographic assessment in guiding PCI - namely, intravascular ultrasound (IVUS) and fractional flow reserve (FFR).
IVUS provides anatomical information regarding the lumen, plaque, and plaque characteristics, and can optimize stent placement minimizing stent-related problems and lead to better clinical outcomes. On the other hand, FFR provides information on amount of ischemia which the stenosis in question is causing, and also improves the quality of PCI which has been demonstrated by multiple previous trials, and current practice guidelines recommend the use of FFR to determine revascularization strategy as Class IA recommendation. Recent trials evaluated comparative prognosis between FFR-guided versus angiograph-guided PCI for non-IRA in patients with acute MI and multivessel disease. FLOWER-MI trial showed comparable clinical outcome between FFR-guided versus angiography-guided PCI for non-IRA in STEMI patients at 1-year follow-up. FRAME-AMI trial showed superiority of FFR-guided PCI over angiography-guided PCI in reducing death, MI, or repeat revascularization during median 3.5 years of follow-up.
Although IVUS and FFR differ in underlying basic concepts, previous studies demonstrated clinical outcomes following treatment decision by IVUS and FFR was similar between the 2 groups. However, these studies mainly evaluated low-risk stable ischemic heart disease patients with intermediate stenosis, and does not reflect population with acute myocardial infarction undergoing complete revascularization. Currently, the data directly comparing the benefit of IVUS and FFR for non-IRA PCI in STEMI is lacking. Considering that coronary atherosclerotic plaque in non-IRA of STEMI patients is associated with significantly higher risk of future clinical events, IVUS would have potential strength of detecting high risk plaque in non-IRA and treatment decision based on plaque characteristics. Conversely, FFR-guided treatment decision for non-IRA would detect functionally significant non-IRA stenosis and treatment decision based on functional significance would reduce unnecessary PCI, as demonstrated by previous trials.
In this regard, randomized controlled trial comparing clinical outcome following non-IRA PCI in STEMI patients with multivessel disease guided by IVUS or FFR would provide valuable evidence to enhance patient's prognosis after treatment of STEMI. Therefore, FRAME-AMI 2 trial is designed to compare clinical outcomes after non-IRA PCI using either IVUS-guided or FFR-guided strategy.

---|---|
Active Comparator: Fractional flow reserve-guided PCI
FFR measurement for non-IRA stenosis (>50% visual estimation) will be performed by continuous infusion of adenosine (140~180 ug/kg/min) or intracoronary nicorandil (2 mg bolus) injection.
The FFR ≤0.80 will be targeted for PCI.
In case of non-IRA stenosis >90%, we will judge FFR value of ≤0.80.

Experimental: Intravascular Ultrasound-guided PCI
In IVUS-guided PCI group, the current trial evaluates clinical outcome following IVUS-guided treatment decision for revascularization of non-IRA stenosis. According to pre-defined criteria, the decision of revascularization will be made. Revascularization criteria in the IVUS-guided PCI group is 1) minimal lumen area (MLA) ≤ 3mm2 or 2) 3mm2 < MLA ≤4mm2 and plaque burden >70%. |
