Silent infarcts on CT may flag higher recurrent risk in AF patients after TIA/stroke; leaves open whether imaging should guide therapy.
Does the presence of silent brain infarcts on CT predict recurrent vascular events in patients with nonrheumatic atrial fibrillation and recent TIA or stroke?
In patients with nonrheumatic atrial fibrillation and recent TIA or stroke, silent brain infarcts on CT are present in 14% of cases and predict an increased risk of recurrent vascular events.
