Background. Glycoprotein (gp) IIb/IIIa-receptor antagonists are highly effective antiplatelet agents with proven efficacy in the treatment of acute coronary and experimental cerebral ischemia. In this study we examined the rate of hemorrhagic transformation and major bleedings in patients with acute stroke treated with tirofiban, a nonpeptide gpIIb/IIIa antagonist. Methods: Eighteen patients with progressively deteriorating acute ischemic stroke were treated with body-weight adjusted intravenous tirofiban for a mean period of 46 h and compared with a matched group of 17 acute ischemic clinically stable stroke patients. Cerebral hemorrhage was assessed by cranial imaging 6-10 days after symptom onset. Results., No major intracranial hemorrhage was observed in either group. Clinically asymptomatic hemorrhagic infarctions type I/II/III were detected in 4/2/0 controls and in 4/ 1/1 patients of the tirofiban group, respectively (OR = 0.92; 95% Cl 0.4-2.5). Clinical outcome scores were not different in both groups (p = 0.18). Conclusions:Tirofiban was not associated with a significantly increased cerebral bleeding rate in acute ischemic stroke. Randomized multicenter studies are needed to further evaluate the safety and efficacy of tirofiban in the treatment of acute stroke. Copyright (C) 2001 S. Karger AG, Basel.
