Background Among patients with atrial fibrillation, the risk of stroke is highest for those with a
history of stroke; however, oral anticoagulants can lower the risk of recurrent stroke by two …

Atrial fibrillation (AF) is a major public health burden worldwide, and its prevalence is set to
increase owing to widespread population ageing, especially in rapidly developing countries …

Cryptogenic (of unknown cause) ischaemic strokes are now thought to comprise about 25%
of all ischaemic strokes. Advances in imaging techniques and improved understanding of …

Background and Purpose—Atrial fibrillation (AF) confers a high risk of recurrent stroke,
although detection methods and definitions of paroxysmal AF during screening vary. We …

Cardiac thromboembolism attributed to atrial fibrillation (AF) is responsible for up to one-
third of ischemic strokes. Stroke may be the first manifestation of previously undetected AF …

Despite major technological advances in ischemic stroke diagnostic techniques, our current
understanding of stroke mechanisms and etiology continues to remain unclear in a …

Background—Atrial fibrillation (AF) is a frequent source of cardiac emboli in patients with
ischemic stroke. AF may be asymptomatic and therefore undiagnosed. Screening for silent …

(TIA), confers a 5-fold increased risk of ischemic stroke. 1, 2 AF-related strokes are
associated with an 50% increased risk of disability and 60% increased risk of death at 3 …

Background and Purpose—Occult paroxysmal atrial fibrillation (AF) is found in a substantial
minority of patients with cryptogenic stroke. Identifying reliable predictors of paroxysmal AF …

While the benefit of oral anticoagulants (OACs) for stroke prevention in patients with atrial
fibrillation (AF) is well established, it is not known whether oral anticoagulation is indicated …
