How this study is set up

The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built
  • Investigator standing0/100

    No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

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.

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.

Eligibility as written in the registry

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

Arms and interventions

  • Physiology-guided Non-Culprit-Lesion (NCL) PCIACTIVE_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.

  • Angiography-guided NCL PCIOTHER

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

Interventions

  • Procedure Angiography-guided NCL PCI

    PCI will be performed as per local practice

  • Procedure Physiology-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.
