研究目的: |
旨在确定低剂量替格瑞洛(每天两次,每次45毫克)在联合阿司匹林治疗下,是否在预防CYP2C19功能缺失携带者轻型卒中或高危TIA患者的90天中风复发方面,不劣于标准剂量替格瑞洛(每天两次,每次90毫克)。 |
||||||||||||||||||||||
|
Objectives of Study: |
To determine whether low-dose ticagrelor (45 mg twice daily) is non-inferior to standard-dose ticagrelor (90 mg twice daily), both combined with aspirin, in preventing 90-day stroke recurrence among CYP2C19 LOF carriers with minor stroke or high-risk TIA. |
