Atrial fibrillation after acute stroke

Summary

Transient atrial fibrillation (AF) may occur after acute stroke, not always causing it. This transient AF, discovered post-stroke, often resolves quickly and may be a consequence of the stroke itself.

Area of Science:

  • Neurology
  • Cardiology
  • Internal Medicine

Background:

  • Atrial fibrillation (AF) is a known stroke risk factor.
  • Cardiac arrhythmias and ECG changes are observed following ischemic stroke and intracranial pathologies.
  • The relationship between acute stroke and new-onset AF requires further investigation.

Purpose of the Study:

  • To test the hypothesis that transient atrial fibrillation (AF) can develop as a consequence of acute stroke.
  • To differentiate between AF as a cause versus a result of stroke.

Main Methods:

  • Prospective analysis of 1,661 first-ever stroke patients from the Lausanne Stroke Registry.
  • Definition of "recent AF" as AF detected at or after hospital admission in patients with no prior AF history.
  • Comparison of recent AF patients with known AF and cardioembolic stroke patients regarding AF evolution, risk factors, and lesion characteristics.

Main Results:

  • Twenty-four patients presented with recent AF on admission; 17 developed it within 3 days post-stroke.
  • AF resolved within days in 63% of recent AF patients (94% of after-admission AF).
  • Primary hematoma stroke type was more prevalent in recent AF (9.8%) compared to known AF (2.8%) and cardioembolic stroke (0.9%). Parietoinsular and brain stem lesions were also more common in recent AF.

Conclusions:

  • AF discovered after acute stroke is often transient, suggesting it may be a consequence of the stroke.
  • The higher incidence of primary hematoma and specific brain lesion locations (parietoinsular, brain stem) in recent AF patients supports the hypothesis of stroke-induced AF.
  • This finding necessitates considering stroke-induced AF in patients with acute stroke and previously unknown AF before treatment decisions.
