Optimal antithrombotic strategy for patients with atrial fibrillation undergoing PCI

Official title: What is the Optimal Antithrombotic Strategy in Patients With Atrial Fibrillation Having Acute Coronary Syndrome or Undergoing Percutaneous Coronary Intervention?

Run by St. Antonius Hospital · NCT04436978 · Data updated 2026-11-12

This study is testing whether a new blood-thinning treatment for patients with atrial fibrillation undergoing heart procedures is safer and just as effective as the traditional approach that includes more medications.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients aged 18 and older who are undergoing successful PCI and have a history of or newly diagnosed atrial fibrillation or flutter with a long-term need for oral anticoagulation.

Probably not a fit

Patients with contraindications to the study medications or those with severe comorbidities such as recent strokes or significant bleeding history may not benefit from this study.

What this trial studies

This study investigates the best antithrombotic management for patients with coronary artery disease and atrial fibrillation who are undergoing percutaneous coronary intervention. It compares the traditional triple antithrombotic therapy, which includes oral anticoagulation and dual antiplatelet therapy, against a newer dual antithrombotic therapy that omits aspirin. The goal is to determine a safer and equally effective treatment approach that minimizes the risk of major bleeding complications while preventing ischemic events. The study will enroll patients who meet specific criteria related to their atrial fibrillation and PCI status.

Why it matters

Potential benefit: If successful, this study could lead to safer treatment options for patients with atrial fibrillation undergoing PCI, reducing the risk of bleeding complications.

How similar studies have gone: Recent studies have shown promising results with dual antithrombotic therapy, suggesting that this approach may be safer than traditional triple therapy.
