Stenting unstable plaques: a new way to prevent second heart attacks?
NCT ID NCT05599061
First seen Jun 25, 2026 · Last updated Jul 16, 2026 · Updated 3 times
Summary
This study looks at 600 people who had a major heart attack and have other narrowings in their heart arteries that are not severe but look unstable. Half will get a stent plus medication, and half will get medication alone. The goal is to see if stenting these unstable plaques reduces the chance of another heart attack or death.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Percutaneous coronary intervention (stenting) plus optimal medical treatment
- What this could lead to
- If it works, this could show that stenting unstable plaques in heart attack patients lowers the risk of future heart attacks or death.
- What could go wrong
- This is an early-stage trial with 600 participants, so results may not apply to everyone. Stenting carries risks like bleeding or vessel damage, and the benefit over medication alone is not yet proven.

Inclusion Criteria: * Patients \> 18 years. * Successful revascularization of the culprit lesion in patients undergoing coronary angiography due to ST-segment elevation (\> 1mm in \> 2 contiguous leads, new left bundle branch block, or true posterior MI with ST depression of \>1mm in \>2 contiguous anterior leads) in the first 72 hours of the symptom's onset. * Multivessel coronary disease with non-culprit lesions located in different vessels than the culprit lesion and ranging from 40 to 69% of DS (visual estimated diameter stenosis ) by visual estimate planned for FFR-guided revascularization in staged procedure (\>24 hours and \<60 days after PCI of the culprit lesion). * Non-culprit lesions should be suitable for functional assessment with pressure wire and OCT catheter and should be suitable to be treated with a single 2.0 to 4.5 mm EES (everolimus-eluting stent ). * Subject agrees to not participate in any other clinical trial study for a period of 4 years following the inclusion in the study. * Informed consent signed. Exclusion Criteria: * Inability to provide informed consent. * Female of childbearing potential (age \<50 years and last menstruation within the last 12 months), who did not undergo tubal ligation, ovariectomy or hysterectomy. * Known intolerance to aspirin, heparin, everolimus, contrast material. * Unresolved mechanical complication or cardiogenic shock at the staged procedure. * Non-culprit study lesions located in the left main coronary artery or in coronary vessels with prior coronary revascularization (PCI or by-pass) or with distal vessel occlusion. * Patients with long, bifurcated, severely angulated or severely calcified non-culprit study lesions non suitable to be treated with a single EES implantation. * Asthma or known history of bronchial hyper-reactivity. * Chronic renal dysfunction with creatinine clearance \< 45 ml/min. * Severe comorbidities that in the opinion of the local investigators determine the patient's life expectancy \< 4 years. * Subject is currently participating in another clinical trial that has not yet completed its primary endpoint.
