NCT05701358

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.

Outcome Measures

Primary Outcomes (2)

  • Efficacy: Time to first occurrence of the composite of CV death, new MI, or IDR

    at study completion, a minimum of 2 years

  • Safety: Time to first occurrence of the composite of clinically significant bleeding, stroke, stent thrombosis, or contrast-associated acute kidney injury.

    at study completion, a minimum of 2 years

Secondary Outcomes (2)

  • Time to first occurrence of the composite of CV death or new MI.

    at study completion, a minimum of 2 years

  • Net clinical outcome: Time to first occurrence of the composite of CV death, new MI, clinically significant bleeding, stroke, stent thrombosis or contrast-associated acute kidney injury.

    at study completion, a minimum of 2 years

Study Arms (2)

Physiology-guided Non-Culprit-Lesion (NCL) PCI

ACTIVE COMPARATOR

Patients randomized to this group will have their physiology assessment using RFR and/or FFR of all qualifying NCLs that were identified prior to randomization. Other validated non-hyperemic physiology ratios (eg. iFR) may only be used when RFR is not available.

Procedure: Physiology-guided NCL PCI

Angiography-guided NCL PCI

OTHER

Patients randomized to this group will undergo routine staged PCI of all qualifying NCLs that were identified prior to randomization.

Procedure: Angiography-guided NCL PCI

Interventions

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.

Physiology-guided Non-Culprit-Lesion (NCL) PCI

PCI will be performed as per local practice

Angiography-guided NCL PCI

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

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

You may not qualify if:

  • Planned or prior coronary artery bypass graft (CABG) surgery
  • 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
  • Prior PCI of a non-culprit lesion in a different vessel from the culprit lesion within 45 days of randomization
  • Planned medical treatment of all qualifying non-culprit lesions (i.e., no PCI)
  • Presence of severe non-culprit-lesion stenosis with reduced epicardial flow (TIMI flow ≤ 2) or \>90% visual diameter stenosis
  • 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)
  • The only qualifying non-culprit lesion is in the same vessel territory as the culprit lesion
  • 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
  • Non-cardiovascular co-morbidity with expected life expectancy \<2 years
  • Any other medical, geographic, or social factor making study participation impractical or precluding 5 year follow-up
