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.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

Inclusion criteria

1.The patient's age is no less than 40 years old. 2. Diagnosed as non-cardiogenic acute non-disabling ischemic stroke (NIHSS score <=3) or high-risk TIA (ABCD2 score >=4). 3. The time from symptom onset to randomization is less than or equal to 72 hours. 4. Confirmed by genetic testing to carry the CYP2C19 loss-of-function allele.

排除标准:

1.对阿司匹林或替格瑞洛有禁忌证。 2.有颅内出血史。 3.需要长期抗凝治疗。 4.活动性出血或高出血风险。 5.过去30天内接受过大手术。 6.严重肝肾功能不全(Child-Pugh C级或CKD 3期及以上)。 7.妊娠或哺乳期。 8.参与可能干扰本研究的其他临床试验。

Exclusion criteria:

1.There are contraindications to aspirin or ticagrelor. 2. Has a history of intracranial hemorrhage. 3. Long-term anticoagulant therapy is required. 4. Active bleeding or high risk of bleeding. 5. Have undergone major surgery within the past 30 days. 6. Severe liver and kidney dysfunction (Child-Pugh grade C or CKD stage 3 or above). 7. Pregnancy or lactation. 8. Participate in other clinical trials that may interfere with this study.
