Are left atrial ejection fraction, left atrial enlargement, and left atrial fibrosis associated with stroke recurrence or new-onset atrial fibrillation in patients with recent stroke?
Left atrial ejection fraction and left atrial enlargement are associated with stroke recurrence and new-onset atrial fibrillation in patients with recent stroke, highlighting the clinical relevance of left atrial cardiomyopathy.
In patients with recent stroke, LAEF and LA enlargement, but not LA fibrosis, are associated with stroke recurrence or new-onset AF. Further studies are required to determine, whether LAEF as a component of ACM is a modifiable risk factor to reduce the risk of recurrent stroke and/or new-onset AF.
Friderichsen et al. (Wed,) studied this question.
