Main objective: To investigate the relationship between the changes in ADP induced platelet aggregation rate, human plasma C4BPα concentration, mRNA expression levels of mARC1 and ABCC3-013 (splicing variant) in peripheral blood leukocytes, and the changes in the mRNA expression levels of ABCC3-013 (splicing variant) in selected hospitalized patients before and on the 3rd and 7th day after antiplatelet therapy, as well as on the 30th and 90th day after follow-up, in accordance with the current guidelines for secondary stroke prevention, and to explore the relative efficacy of each biomarker in predicting clopidogrel resistance; 2. Secondary objective: To collect blood samples from patients, extract their DNA samples, perform CYP2C19 genotyping, validate and evaluate the predictive efficacy and clinical application value of a biomarker "panel" composed of multiple new and old biomarkers for predicting clopidogrel resistance.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据采集:在经过患者同意后由参与临床研究的医师通过专门临床病例表进行采集。 数据管理:本研究中的所有数据均妥善保管,确保安全无丢失及泄露。不随意上传敏感信息及患者信息至公共平台。数据处理过程中,将患者的个人信息去敏感处理,并使用患者识别码表替代患者姓名及ID。如需技术服务,确保数据相应加密处理,并签订保密协议。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection: After obtaining the patient's consent, physicians participating in the clinical study will collect data through a specialized clinical case table. Data management: All data in this study are properly stored to ensure security and prevent loss or leakage. Do not upload sensitive information and patient information to public platforms at will. During the data processing, the patient's personal information is anonymized and a patient identification code table is used instead of the patient's name and ID. If technical services are required, ensure that the data is encrypted accordingly and sign a confidentiality agreement.
