研究目的:

(1)首要目标:验证替罗非班联合尼莫地平较替罗非班单药治疗可显著改善END患者7天内神经功能。 (2)次要目标: 1)明确联合治疗对90天优秀结局的改善幅度。 2)评估联合治疗的安全性(出血事件、低血压及其他不良反应发生率)。  

Objectives of Study:

(1) Primary Objective: To verify whether tirofiban combined with nimodipine significantly improves neurological function within 7 days in END patients compared to tirofiban monotherapy. (2) Secondary Objectives: To determine the magnitude of improvement in excellent functional outcomes at 90 days with combination therapy. To evaluate the safety of combination therapy (incidence of bleeding events, hypotension, and other adverse reactions).

Exclusion criteria:

(1) Culprit large-to-medium artery stenosis >=70% or evidence of cardioembolism. (2) Severe hepatic/renal dysfunction (eGFR <30 mL/min/1.73m2). (3) Hemorrhagic tendency (PLT <100×10?/L or INR >1.4).
