Efficacy and safety of tirofiban in acute ischemic stroke patients with early neurological deterioration / 国际脑血管病杂志

ABSTRACT

Objective:To investigate the efficacy and safety of tirofiban in patients with acute ischemic stroke (AIS) with early neurological deterioration (END).Methods:Consecutive patients with AIS who had END and did not receive reperfusion treatment admitted to Xuzhou Municipal Hospital Affiliated to Xuzhou Medical University within 24 h of onset from January 2017 to December 2022 were retrospectively included. END was defined as an increase of ≥2 in the National Institutes of Health Stroke Scale score within 72 h after onset compared at admission, or an increase of 1 in motor function. The tirofiban group was given tirofiban within 2 h after the occurrence of END, while the control group was given aspirin+clopidogrel. A score of ≤2 on the modified Rankin Scale at 90 d after onset was considered as a good outcome.Results:A total of 502 patients with AIS who had END were enrolled; including 322 males (64.14%) aged 65 ± 9 years. There was no statistically significant difference in baseline characteristics between the tirofiban group ( n=252) and the control group ( n=250). The good outcome rate of the tirofiban group at 90 d was significantly higher than that of the control group (60.32% vs. 42.00%; P<0.05), while there were no statistically significant differences in the incidence of symptomatic hemorrhagic transformation, asymptomatic hemorrhagic transformation, death and serious adverse events within 90 d. There were statistically significant differences in diabetes, atrial fibrillation, use of tirofiban, and the classification of stroke etiology between the good outcome group and the poor outcome group ( P<0.05). Multivariate logistic regression analysis showed that the use of tirofiban was an independent correlated factor for good outcome (odds ratio 0.33, 95% confidence interval 0.22-0.48; P<0.001). Conclusion:Tirofiban has good efficacy and safety for END in patients with AIS who did not received reperfusion therapy.
