BACKGROUND AND PURPOSE: Whether tirofiban is safe and effective in cardioembolic stroke patients treated with endovascular thrombectomy (EVT) remains unknown; this study evaluated the safety and efficacy of low-dose tirofiban in this patients population.
METHODS: This study was a prospective registry study. Patients with cardioembolic stroke undergoing EVT from January 2013 to December 2020 were treated with EVT alone or EVT plus low-dose tirofiban. The primary outcome was symptomatic intracerebral hemorrhage (sICH) prior to discharge. The secondary outcomes included reocclusion, in-hospital mortality, and 3-month functional outcomes.
RESULTS: Overall, 288 patients were recruited and 117 received low-dose tirofiban; 137 patients (47.6%) experienced ICH, 42 patients (14.6%) were sICH, and 23 patients (8%) were fatal ICH. Thirteen patients (11.1%) receiving tirofiban and 29 patients (17.0%) not receiving tirofiban experienced sICH (p = 0.167). Reocclusion occurred in nine patients (7.7%) receiving tirofiban and 15 patients (8.8%) not receiving tirofiban (p = 0.745). The rates of hernia (6.8% versus 20.5%) and decompressive craniectomy (2.6% versus 11.7%) were significantly lower in patients receiving tirofiban (p < 0.01). At 3-month follow-up, functional independence was achieved in 39 patients(33.3%) receiving tirofiban and 43 patients (25.1%) not receiving tirofiban (p = 0.131). Tirofiban was associated with lower odds of in-hospital mortality (3.4% versus 12.3%; adjusted odds ratio, 0.16; 95% confidence interval, 0.03-0.81; adjusted p = 0.027).
CONCLUSIONS: In patients with cardioembolic stroke undergoing EVT, tirofiban is not associated with higher sICH, it seems to lead to lower odds of in-hospital death. Further investigations are needed to confirm these results and to determine the optimal treatment protocols of tirofiban.
