Does prior use of antiplatelet therapy modify the effect of dual antiplatelet therapy in transient ischaemic attack/minor ischaemic stroke: A systematic review and meta-analysis.

It was found that the effectiveness of dual antiplatelet therapy in patients with minor ischaemic stroke or high risk transient ischaemic attack does not significantly differ in patients with prior aspirin exposure; therefore there should be no influence on the decision to use dual antiplatelet therapy.
