Associations between migraine, atrial fibrillation, and heart abnormalities in ischemic stroke

Takeaway

  • In a cohort study of individuals with acute brain ischemia, there was no association between migraine and atrial fibrillation (AF), but there was an association between migraine and patent foramen ovale (PFO) heart abnormalities, especially in people with migraine with aura (MA).

Why this matters

    The biological mechanisms linking ischemic stroke  and MA are unclear, these results suggest future studies are warranted to investigate mechanisms underlying PFO and MA.
