Background And PurposeDual antiplatelet therapy (DAPT) with aspirin and clopidogrel for 90 days was recommended as the secondary prevention of minor ischaemic strokes or transient ischaemic attacks (TIAs) in 2014. However, whether the duration of 90 days is optimal for each patient remains unclear. Therefore, the efficacy and safety of short-term (≤3 months) and prolonged (≥1 year) DAPT after stroke or TIA were assessed via a systematic review and meta-analysis.MethodsThe Cochrane Library, Clinical Trials.gov and PubMed were searched up to December 2014 and nine randomized controlled trials were included involving 21 923 patients.ResultsShort-term DAPT significantly reduced the risk of ischaemic stroke recurrence by 41% and major vascular events by 30%, without increasing the risk of intracranial haemorrhage. Prolonged DAPT reduced the risk of ischaemic stroke recurrence by 12% and major vascular events by 10%. However, the risk of major bleeding and intracranial haemorrhage increased.ConclusionsShort-term DAPT appears to be superior to prolonged DAPT. However, the difference in efficacy outcome needs to be carefully explained and confirmed by further well-designed randomized controlled trials.© 2016 EAN.
