May inform etiology assessment in AF stroke; hypothesis-generating and requires prospective validation.
Which clinical characteristics and echocardiographic findings are associated with a cardioembolic mechanism of stroke in patients with atrial fibrillation?
Specific clinical characteristics strongly predict a cardioembolic mechanism for stroke in patients with atrial fibrillation, whereas left atrial enlargement reflects underlying cardiopathy rather than embolic risk.
D'Olhaberriague et al. (1989) studied this question.
