Early rhythm-control therapy for stroke patients with atrial fibrillation

Official title: Early Treatment of Atrial Fibrillation for Stroke Prevention Trial in Acute STROKE

Run by Universitätsklinikum Hamburg-Eppendorf · NCT05293080 · Data updated 2026-11-12

This trial tests whether starting rhythm-control treatment early after an acute ischemic stroke in people with atrial fibrillation can reduce recurrent strokes and other heart-related problems, compared with usual care.

Is this trial a fit for you?

Likely a good fit

Adults with acute ischemic stroke within the past four weeks and newly diagnosed atrial fibrillation (AF detected ≤1 year before randomization) who can start rhythm-control therapy within four weeks after stroke.

Probably not a fit

Patients who are not suitable for rhythm-control therapy due to other cardiac conditions or who have very limited life expectancy may not benefit.

What this trial studies

EAST-STROKE is a multicenter, randomized, PROBE study designed to see if early comprehensive rhythm control for atrial fibrillation after acute ischemic stroke improves cardiovascular outcomes. Participants may receive antiarrhythmic drugs, ablation, or electrical cardioversion as part of the rhythm-control strategy, or standard care as a control. The primary outcome combines recurrent stroke, cardiovascular death, and hospitalizations for heart failure or acute coronary syndrome, with secondary outcomes including safety, health status, and socio-economic factors. The trial uses an adaptive design and aims to enroll up to 1,746 patients with 90% power. The study is investigator-initiated and includes blinded outcome assessment to reduce bias.

Why it matters

Potential benefit: If successful, early rhythm-control treatment could lower the risk of recurrent strokes and other cardiovascular events after an ischemic stroke in patients with atrial fibrillation.

How similar studies have gone: Prior research in rhythm-control strategies after stroke is limited; this trial tests a comprehensive early approach in a large, multicenter setting.
