Comparison Of Reduced DAPT Followed by P2Y12 Inhibitor Monotherapy With Prasugrel vs stAndard Regimen in STEMI Patients

To be considered for this study, you would first need to be admitted to the hospital with a severe type of heart attack called a STEMI, and your doctors must be planning to treat you with a procedure to open up your blocked heart artery. You would also need to show signs of a heart attack on an ECG (heart tracing).

If you have multiple narrowed heart arteries, doctors would initially only treat the main blocked one. Then, about 1 to 1.5 months later, if you've followed your DAPT medicine plan, haven't had any serious complications like another heart attack or major bleeding, and your initial procedure was successful, you might be eligible for the next stage of the study. This second stage is where you'd be randomly assigned to one of the treatment groups.

There are also some reasons why you might not be able to join. For example, if you're already taking medicines to thin your blood (anticoagulants), or if you've had a stroke or mini-stroke within the last year. Also, if you have certain severe liver problems, active bleeding, or a history of allergic reactions to the study medicines, you wouldn't be able to participate. Your doctor will carefully check all these points with you.

If you decide to take part, your journey would generally follow these steps:

1. **Initial Treatment:** When you first have your heart attack, you'll receive standard emergency treatment, including medicines like aspirin and prasugrel, and a procedure to open up your blocked artery. 2. **Addressing Other Narrowed Arteries (if needed):** If you have other narrowed arteries, these would typically be treated within 15 days of your first procedure. For some patients, the study will compare whether using a special camera (OCT) or standard X-ray imaging (angiography) to guide these extra treatments is better. 3. **Random Assignment (Month 1-1.5):** About 30-45 days after your initial heart attack treatment, if you meet all the criteria (e.g., no major complications, taking your medicines as prescribed), you'll be randomly assigned to one of two groups: either a shorter course of prasugrel plus another anti-clotting medicine followed by prasugrel alone, or the standard longer course of two anti-clotting medicines. 4. **Follow-up:** Your health will be carefully monitored for a long time – about 35 months (nearly 3 years) after you've been assigned to a treatment group. Your doctors will check in with you at 11 months and again at 35 months to see how you're doing and track any health outcomes.
