Brief summary

COMPLETE-2 is a prospective, multi-centre, randomized controlled trial comparing a strategy of physiology-guided complete revascularization to angiography-guided complete revascularization in patients with acute ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI) and multivessel coronary artery disease (CAD) who have undergone successful culprit lesion Percutaneous Coronary Intervention (PCI). COMPLETE-2 OCT is a large scale, prospective, multi-centre, observational, imaging study of patients with STEMI or NSTEMI and multivessel CAD in a subset of eligible COMPLETE-2 patients.

Detailed description

COMPLETE-2 STUDY OBJECTIVES 1. To determine whether a strategy of physiology-guided complete revascularization is non-inferior to a strategy of angiography-guided complete revascularization on the efficacy composite outcome of cardiovascular (CV) death, new myocardial infarction (MI) or ischemia-driven revascularization (IDR). 2. To determine whether a physiology-guided complete revascularization strategy is superior to an angiography-guided complete revascularization strategy in reducing the safety composite outcome of clinically significant bleeding, stroke, stent thrombosis or contrast-associated acute kidney injury.

Interventions

PROCEDUREPhysiology-guided NCL PCI

For RFR, PCI will be performed as per local practice for all lesions with RFR ≤0.89. For FFR, PCI will be performed as per local practice for all NCLs with FFR ≤0.80.

PROCEDUREAngiography-guided NCL PCI

PCI will be performed as per local practice

Inclusion criteria

1. Patients presenting with STEMI or type 1 NSTEMI and within 72 hours of successful culprit-lesion PCI 2. Residual coronary artery disease defined as at least 1 additional non-infarct-related coronary artery stenosis that meets all of the following criteria: 1. Amenable to successful treatment with PCI 2. At least 50% diameter stenosis by visual estimation 3. At least 2.5 mm in diameter 3. Planned complete revascularization strategy for qualifying MI

Exclusion criteria

1. Planned or prior coronary artery bypass graft (CABG) surgery 2. Inability to clearly identify a culprit lesion for STEMI or NSTEMI based on angiographic appearance and/or ECG changes and/or regional wall motion abnormalities 3. Prior PCI of a non-culprit lesion in a different vessel from the culprit lesion within 45 days of randomization 4. Planned medical treatment of all qualifying non-culprit lesions (i.e., no PCI) 5. Presence of severe non-culprit-lesion stenosis with reduced epicardial flow (TIMI flow ≤ 2) or \>90% visual diameter stenosis 6. Presence of a chronic total occlusion (CTO) if it is the only qualifying non-culprit lesion (patients with a CTO plus additional qualifying non-culprit lesions are eligible) 7. The only qualifying non-culprit lesion is in the same vessel territory as the culprit lesion 8. Baseline STEMI or NSTEMI was due to a suspected non-atherothrombotic mechanism such as type 2 MI (supply-demand mismatch), including spontaneous coronary artery dissection or coronary artery embolism 9. Non-cardiovascular co-morbidity with expected life expectancy \<2 years 10. Any other medical, geographic, or social factor making study participation impractical or precluding 5 year follow-up
