Efficacy and Safety of Tirofiban for Patients With BAD (BRANT)

Summary

Branch atheromatous disease (BAD)-related stroke, characterized by subcortical single infarcts without severe stenosis of the large artery, but with a clear atherosclerotic mechanism, is now regarded as a separate stroke type. BAD is associated with early neurological deterioration and poor prognosis, but is lack of effective therapy. The goal of this randomized controlled trial is to test the efficacy and safety of intravenous tirofiban in patients with acute ischemic stroke caused by branch atheromatous disease. The main question it aims to answer is: Compared with standard antiplatelet therapy based on current stroke guideline, whether tirofiban used in acute phase of BAD could improve the proportion of excellent functional outcome (modified Rankin Scale: 0-1) at 90 days. Researcher will also compare the rate of major bleeding between treatment and control groups.
