One drug at a time: could a simpler blood thinner strategy cut bleeding risk after stents?

NCT ID NCT05955365

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new approach for people with atrial fibrillation who have just received a coronary stent. Instead of taking multiple blood thinners together for months, the experimental group takes only one antiplatelet drug for the first month, then switches to a single anticoagulant. The goal is to see if this simpler routine reduces bleeding complications while still preventing heart attacks, strokes, and stent blockages. About 3,000 participants will be compared to those receiving the standard combination therapy.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

P2Y12 inhibitor (antiplatelet drug) followed by a direct-acting oral anticoagulant (DOAC)

What this could lead to

If this works, it could offer a simpler, safer blood-thinning routine for people with atrial fibrillation who have just had a coronary stent, lowering their risk of serious bleeding without raising the chance of heart attack or stroke.

What could go wrong

This is a large Phase 4 trial, but the strategy is still experimental. It may not protect against stent clotting or stroke as well as the current triple-drug approach, and individual responses to the drugs can vary.
