Conclusion:
In conclusion, our study adds to the existing body of evidence by
reaffirming the established associations between atrial cardiopathy,
stroke subtypes, and atrial fibrillation (AF) in a geographically
distinct population. Our findings highlight the association between
lower LA strain and ESUS stroke subtype, as well as the higher
prevalence of AF in ESUS patients, which supports the hypothesis that
atrial cardiopathy plays an important role in the mechanistic pathway of
ESUS. Consequently, we propose that incorporating routine quantification
of LA strain may be a valuable tool for clinicians in risk
stratification and selecting appropriate secondary prevention strategies
for ESUS patients identified at high risk of recurrence.
