Background: Different stroke etiologies are associated with varied incidences of early neurological deterioration (END) in patients with acute ischemic stroke (AIS). The Tirofiban for the Prevention of Neurological Deterioration in Acute Ischemic Stroke (TREND) trial demonstrated the efficacy of tirofiban in preventing END in patients with AIS. Herein, we conducted a pre-specified subgroup analysis of this trial data to investigate whether stroke etiologies influenced the effects of tirofiban. Methods: We performed a pre-specified subgroup analysis of the TREND trial, including 413 patients with AIS classified into large-artery atherosclerosis (n = 114), small-vessel occlusion (n = 124), and undetermined etiology (n = 175). The primary outcome was the incidence of END 4 (defined as an increase in the National Institutes of Health Stroke Scale (NIHSS) score by ⩾ 4 points) within 72 h. Other outcomes included END 2 (increase in NIHSS score by ⩾ 2 points), early improvement, functional outcomes at 90 days, and safety profiles. Results: Tirofiban significantly reduced the risk of END 4 in patients with large-artery atherosclerosis (4.1% vs. 21.5%; adjusted odds ratio (OR), 0.17; 95% confidence interval (CI), 0.04–0.78; P = 0.023), while no significant differences were observed in small-vessel occlusion (adjusted OR, 0.24; 95% CI, 0.02–2.67; P = 0.248) and undetermined etiology (adjusted OR, 0.53; 95% CI, 0.18–1.55; P = 0.247) subgroups (P for interaction = 0.376).
