Antiplatelet Drug, Ischemic Stroke
Conditions
Brief summary
1. Main objective: To explore the efficacy of precise antiplatelet therapy guided by platelet aggregation function in reducing the incidence of 30 day platelet hyperresponsiveness in patients with non-cardiogenic ischemic stroke. 2. Secondary objective: To explore the efficacy and safety of antiplatelet therapy in patients with non-cardiogenic ischemic stroke under the guidance of platelet aggregation function.
Detailed description
Non cardiac cerebral infarction accounts for more than 50% of cerebral infarction cases, and the key to its onset is increased platelet aggregation function. Aspirin and clopidogrel are Class A recommended drugs for the prevention and treatment of non cardiac cerebral infarction. However, after regular use of aspirin and clopidogrel, more than 30% of stroke patients still experience high on treatment platelet reactivity (HOPR) due to aspirin resistance and clopidogrel resistance, leading to stroke recurrence. Antiplatelet therapy is the cornerstone of the prevention and treatment of non cardiogenic cerebral infarction. Therefore, clinical research on the prevention and treatment of HOPR with antiplatelet therapy for non cardiogenic cerebral infarction is of great significance, which can help partially solve the bottleneck of resistance to antiplatelet therapy in cerebral infarction.Platelet aggregation function testing can timely detect antiplatelet therapy HOPR, guide drug adjustment, and is expected to become a testing standard for the prevention and treatment of antiplatelet therapy resistance.
Interventions
DRUGPrecision Antiplatelet Therapy Trial Group
Use SPCM method to detect platelet aggregation function in patients, adjust antiplatelet drugs based on the test results, and receive precise antiplatelet treatment for 12 months. Non resistant patients with aspirin will continue to receive aspirin 100mg qd; Patients with aspirin resistance were given clopidogrel 75mg qd; Clopidogrel resistant patients were given ticagrelor 90mg bid.
DRUGTraditional Antiplatelet Therapy Control Group
No adjustment of antiplatelet medication is required, and routine treatment with aspirin 100mg qd is given for 12 months.
