Heart assessment to check repeat-stroke risk in people with atrial fibrillation

CARE-AF: Cardiac Assessment for Recurrent Stroke Risk Evaluation in Atrial Fibrillation

Observational Insel Gruppe AG, University Hospital Bern · NCT06954610

This project will test whether detailed heart examinations can find which people with atrial fibrillation who just had an ischemic stroke are at high risk of having another stroke.

What this trial studies

This observational cohort enrolls adults with known or newly diagnosed atrial fibrillation who present with an acute ischemic stroke within seven days. Participants receive detailed cardiac evaluations (for example cardiac imaging, rhythm monitoring, and review of anticoagulation) and clinical data are collected. Patients are followed over time for recurrent stroke and related outcomes without changing prescribed treatments. The goal is to identify cardiac features linked to so-called "breakthrough" strokes despite anticoagulation.

Who should consider this trial

Good fit: Adults (≥18 years) with permanent, persistent, or paroxysmal atrial fibrillation and an acute (≤7 days) symptomatic ischemic stroke who can give informed consent are ideal candidates.

Not a fit: People without atrial fibrillation, without a recent ischemic stroke, those with life expectancy under one year, or those unable to attend follow-up visits are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the results could help clinicians identify high-risk patients and guide closer monitoring or targeted interventions to prevent repeat strokes.

How similar studies have performed: Previous trials of anticoagulants documented a residual risk of breakthrough stroke and some observational work has suggested cardiac markers may predict recurrence, but clear, validated predictors are still lacking.
