Conditions
Brief summary
Cerebrovascular disease is the main cause of death and severe long-term disability worldwide. Antiplatelet drugs are the main drugs for ischemic stroke and TIA. Cyclooxygenase inhibitor acetylsalicylic acid (ASA) has always been the most widely studied antiplatelet therapy. The studies of acrates of aliscon body evaluated the efficacy and safety of ticagrelor monotherapy in preventing major vascular events in patients with AIS or TIA. The results showed that the number of patients with endpoint events in ticagrelor group was less than that in ASA group, However, it has not been proved that ticagrelor monotherapy is better than ASA. The purpose of this study is to prove that ticagrelor is better than ASA.

The results showed that the number of patients with endpoint events in ticagrelor group was less than that in ASA group, However, it has not been proved that ticagrelor monotherapy is better than ASA. The purpose of this study is to prove that ticagrelor is better than ASA. The study will be designed as a randomized, double-blind, placebo-controlled, parallel grouping study and conducted in multiple centers to ensure the representation of multiple countries, races and races, so as to ensure that the results of the study can be widely applied.
Interventions
DRUGticagrelor + ASA
On day 1, ticagrelor loading dose (2 tablets, ticagrelor 90mg) was given, followed by ticagrelor 90mg, twice daily Basic treatment: the first day received ASA loading dose, 300-325mg, and the server received ASA 75-100mg, once a day
DRUGPlacebo+ASA
Placebo loading dose on day 1 (2 tablets, matched with ticagrelor 90mg), followed by placebo twice daily (matched with ticagrelor 90mg) Basic treatment: the first day received ASA loading dose, 300-325mg, and the server received ASA 75-100mg, once a day
