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

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
