Why the study?
Do baseline CT characteristics reliably distinguish between strokes of presumed cardioembolic origin and those caused by arterial disease in patients with TIA or minor ischaemic stroke?
Population
3,972 patients with transient ischaemic attack or minor ischaemic stroke, comprising two prospective cohorts…
Comparison
Presence of non-rheumatic atrial fibrillation vs Sinus rhythm (SR) / absence of NRAF

Overlapping CT features preclude reliable etiology distinction in NRAF-related stroke; leaves open whether imaging can differentiate cardioembolic from atherothrombotic mechanisms.
Do baseline CT characteristics reliably distinguish between strokes of presumed cardioembolic origin and those caused by arterial disease in patients with TIA or minor ischaemic stroke?
Baseline CT characteristics overlap significantly and cannot reliably distinguish between cardioembolic and atherosclerotic causes of stroke in patients with non-rheumatic atrial fibrillation.
Latum et al. (1995) studied this question.
