Physiology-guided vs Angiography-guided Non-culprit Lesion Complete Revascularization for Acute MI & Multivessel Disease
(COMPLETE-2)
What this study is about
COMPLETE-2 is a forward-looking, multi-centre, randomly assigned 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, forward-looking, multi-centre, observational, imaging study of patients with STEMI or NSTEMI and multivessel CAD in a subset of eligible COMPLETE-2 patients.

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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 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
Exclusion criteria
- 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

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
