Why the study?
Does atrial fibrillation increase the risk of stroke/TE/TIA in the presence or absence of other risk factors?
Does atrial fibrillation increase the risk of stroke/TE/TIA in the presence or absence of other risk factors?
Atrial fibrillation independently increases the risk of stroke/TE/TIA, with the relative impact being highest in the absence of other risk factors.
Stroke/TE/TIA risk was particularly increased when prior stroke/TE/TIA was present. Atrial fibrillation is associated with an increase in risk of stroke/TE/TIA in the absence of other risk factors but only a moderate increase in risk when other risk factors are present.
