The safety and efficacy endpoints at 3-month follow-up were symptomatic intracranial haemorrhage (sICH), recanalisation rate, clinical outcome and mortality.Results Among 915 patients who had AIS, those in APT group (n=199) showed shorter puncture-to-recanalisation time, lower frequency of intravenous thrombolysis and more use of tirofiban compared with those in non-antiplatelet group (n=716) (p\<0.05 for all). Oral APT was found to be associated with superior clinical outcome compared with non-APT (APT (44.2\%) versus non-APT (41.1\%)), adjusted OR=2.605, 95\% CI 1.244 to 5.455, p=0.011). DAPT showed superior clinical outcome compared with non-APT (DAPT (56.5\%) versus non-APT (41.1\%), adjusted OR=5.405, 95\% CI 1.614 to 18.102, p=0.006) and lower risk of mortality at 3-month follow-up (DAPT (4.8\%) versus non-DAPT (17.7\%), adjusted OR=0.008, 95\% CI 0.000 to 0.441, p=0.019). There was no significant difference in sICH between the two groups.Conclusions Oral APT prior to undergoing EVT is safe and may accompany with superior clinical outcomes. DAPT may associate with superior clinical outcomes and lower risk of mortality.Data are available on reasonable request.
