Case-Control study 

研究目的:

本研究拟纳入未经溶栓24小时内予双抗或溶栓后24小时后进行双抗治疗的卒中患者,观察其是否发生早期神经功能恶化,并进行病因学分析。创新之处在于本研究虑到脑卒中患者阿司匹林基因代谢、CYP2C19基因型及C反应蛋白及纤维蛋白原含量、血小板聚集率与早期神经功能的相关性,大部分国内外研究对此未关注。  

Objectives of Study:

This study intends to enroll stroke patients who did not receive dual-antibody therapy within 24 hours of thrombolysis or received dual-antibody therapy within 24 hours after thrombolysis to observe whether early neurological deterioration occurs and to analyze the etiology. The innovation is that this study takes into account the correlation of aspirin gene metabolism, CYP2C19 genotype, C-reactive protein and fibrinogen content, platelet aggregation rate and early neurological function in stroke patients, and most domestic and foreign studies have not paid attention to this.
