Screening of Atrial Fibrillation in Cryptogenic Ischemic Stroke-Does Timing Make the Difference?

The presence of subtle atrial abnormalities was strongly associated with a higher incidence of silent AF although neither the left ventricular ejection fraction nor any of the left atrial measurements like left atrial dilatation, which have been shown to be associated with AF in CIS patients [ 1 , 12 ], were nonsignificant, likely due to the small sample size despite a positive trend.
