ABSTRACT
BACKGROUND:
The use of tirofiban as an adjunct to endovascular therapy (EVT) for acute ischemic stroke has been controversial. We aimed to assess the differences in safety and efficacy of EVT adjuvant to tirofiban in patients with anterior circulation stroke (ACS) and posterior circulation stroke (PCS).METHODS:
We systematically searched Pubmed, Embase, Cochrane Library, and Web of Science. Cohort studies and randomized controlled trials that compared treatment with tirofiban combined with EVT and EVT alone were included in our meta-analysis. The safety outcomes were symptomatic intracranial hemorrhage, and 3-month mortality. The efficacy outcomes were good functional outcome, excellent functional outcome, and successful recanalization (mTICIâ ≥â 2b). We performed subgroup analyses of anterior and posterior circulation strokes.RESULTS:
We included 15 studies with 4608 patients. For safety outcomes, tirofiban significantly reduced 3-month mortality in the ACS subgroup (odd ratio [OR]â =â 0.80, 95% confidence interval [CI]â =â 0.65-0.98, Pâ =â .03) without increasing the rate of symptomatic intracranial hemorrhage (ORâ =â 1.12, 95% CIâ =â 0.88-1.44, Pâ =â .35). In the PCS subgroup, tirofiban significantly reduced 3-month mortality (ORâ =â 0.63, 95% CIâ =â 0.50-0.80, Pâ =â .0001) and symptomatic intracranial hemorrhage (ORâ =â 0.60, 95% CIâ =â 0.37-0.95, Pâ =â .03). For efficacy outcomes, in the ACS subgroup, tirofiban significantly improved good functional outcome (ORâ =â 1.24, 95% CIâ =â 1.06-1.45, Pâ =â .008) but did not improve recanalization (ORâ =â 1.17, 95% CIâ =â 0.93-1.47, Pâ =â .17) and excellent functional outcome (ORâ =â 1.19, 95% CIâ =â 0.97-1.46, Pâ =â .10). In the PCS subgroup, tirofiban significantly improved recanalization rate (ORâ =â 1.94, 95% CIâ =â 1.43-2.65, Pâ <â .0001) and did not improve good functional outcome (ORâ =â 1.03, 95% CIâ =â 0.81-1.30, Pâ =â .81) and excellent functional outcome (ORâ =â 0.84, 95% CIâ =â 0.58-1.20, Pâ =â .34).CONCLUSION:
In acute ischemic stroke patients undergoing EVT, tirofiban improves good functional outcomes in ACS patients and increases recanalization rates in PCS patients on the 1 hand, reduces mortality, and does not increase the risk of symptomatic intracranial hemorrhage on the other. Tirofiban is safe and effective in both anterior circulation stroke and posterior circulation stroke patients undergoing EVT. More large multicentre randomized controlled studies are needed in the future.
