Safety and efficacy of eptifibatide in acute ischemic stroke requiring extracranial carotid artery stenting.

ABSTRACT

BACKGROUND: The antiplatelet management in acute ischemic stroke requiring carotid artery stenting is heterogenous, with no clear guidelines to direct management. OBJECTIVE: To evaluate the safety and efficacy of an intravenous eptifibatide protocol in the management of acute ischemic stroke requiring emergent carotid artery stenting. METHODS: We performed a retrospective analysis of consecutive patients who underwent carotid artery stenting for acute ischemic stroke at a high-volume tertiary neuroscience center, who were managed with an intravenous eptifibatide protocol. The protocol consists of an intravenous loading eptifibatide bolus (180 mcg/kg) at the time of stenting, followed by a maintenance infusion of 1 mcg/kg/min, then oral or nasogastric loading of dual antiplatelet agents. RESULTS: 80 patients were included for analysis. Median presenting NIHSS was 17. Sixty-six patients (83%) had a tandem intracranial occlusion. Six (7.5%) patients developed symptomatic intracranial hemorrhage (sICH). Those who received intravenous thrombolysis were not more likely to develop sICH (10% vs 5%, p = 0.40). Those patients with a presenting ASPECTS <8 were significantly more likely to develop sICH than those with ASPECTS 8-10 (25% vs 3%, p = 0.004). CONCLUSIONS: Eptifibatide may have a role in the management of acute stroke requiring carotid stenting. Caution may be required in those with established infarct on presentation imaging.
