Clinical characterization of embolic strokes of unknown source versus strokes of other aetiologies

Takeaway

  • Clinical characteristics of patients who have had embolic stroke of unknown source (ESUS), including prevalence of atrial cardiopathy, differ significantly from those of patients with strokes attributed to large artery atherosclerosis (LAA), small vessel disease (SVD), or cardioembolic (CE) aetiologies.

Why this matters

    A substantial portion of stroke patients have ESUS (20–25%), and better characterization may provide insight regarding optimal treatment and prevention.
