Objective:

This paper aims to amalgamate randomized clinical trials studying the safety and efficacy of tirofiban in comparison to other anti-platelet agents in patients with AIS who did not receive reperfusion treatments.  

Background:

Reperfusion treatments with intravenous thrombolysis and endovascular thrombectomy after acute ischemic stroke (AIS) can improve patients’ outcomes significantly. Yet, a substantial portion of patients miss the opportunity to receive reperfusion treatments. In this study, we aimed to assess the role of intravenous tirofiban in this specific population.

Design/Methods:

A search was performed in Embase, Cochrane Central Register of Controlled Trials, Medline, and Web of Science databases from inception until August 2024. The random-effects model was used to calculate odds ratios (ORs) with their corresponding 95% confidence intervals (CIs). Efficacy endpoints included excellent (modified Rankin scale of 0-1) and good (modified Rankin scale of 0-2) functional outcomes at 90 days. Safety outcomes included symptomatic intracerebral hemorrhage (sICH), any ICH, and 90-day mortality.

Results:

Four randomized clinical trials, including a total of 1199 patients, were included. Of these, 599 patients (50%) received tirofiban. The meta-analysis demonstrated that tirofiban was associated with significantly higher rates of both excellent (OR 1.63 [95% CI, 1.24-2.13]; I2= 0) and good (OR 1.65 [95% CI, 1.19-2.29]; I2= 0) functional outcomes at 90 days. No significant differences were observed in sICH, any ICH, or 90-days mortality.  

Conclusions:
Treatment with intravenous tirofiban can be beneficial without increased risk in patients with AIS who are not eligible for reperfusion treatment. Further studies are still needed to validate the generalizability of these findings.
