The study is a multi-centre, Open-label, Randomized Controlled, 1:1 trial comparing Prasugrel-based short DAPT (30-45 days) followed by Prasugrel monotherapy versus standard DAPT regimen in STEMI patients in terms of safety and efficacy endpoints.
In the subgroup of STEMI patients with MVD, a sub-randomization will allow a comparison between a complete revascularization OCT-guided versus complete revascularization angiography-guided stent in terms of efficacy and safety endpoints.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
Eligibility at index procedure
All STEMI patients who are planned to be treated with PCI:
ST segment elevation myocardial infarction
Chest discomfort suggestive of cardiac ischemia ≥20 min at rest with 1 of the following ECG features:
* ST segment elevation ≥2 contiguous ECG leads
* new or presumably new left bundle branch block
In patients with multivessel disease, treatment only of the culprit lesion / target vessel during primary PCI is recommended.
Eligibility at 30-45 days
* All patients who have provided informed consent
* Compliance to DAPT with no regimen modifications (Non-adherence Academic Research Consortium 0)
* No occurrence of significant event (such as MI, unplanned revascularisation, stent thrombosis, stroke, major vascular complication/bleeding BARC Types 3 or greater).
* Successful revascularization: - Successful delivery and deployment of the Study device(s), with final residual stenosis of \<30% (visually) for all target lesions.
* Complete revascularization performed when more than 1 significant lesion, during the index procedure or in staged procedure(s) occurring within 15 days from the index procedure. Physiologic assessment highly recommended for lesions with stenosis between 50% and 90%.
Exclusion criteria
* Patients on oral anticoagulation
* Contraindication to P2Y12 inhibitors and/or to Cardioaspirin or to any of the excipients (hypersensitivity, history of any stroke or transient ischemic attack within the last 12 mo…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
non inferiority of a Prasugrel-based short DAPT (30-45 days) followed by Prasugrel 11 month monotherapy versus standard 12 month DAPT regimen
Timeframe: 11 months
2
superiority of an Optical Coherence Tomography (OCT)-guided revascularization completion as compared to a standard angiography-guided revascularization completion.
