Safety and Efficacy of Edoxaban and Rivaroxaban to Cerebral Venous Thrombosis in Chinese Patients

The goal of this observational study is to learn the safety and efficacy of edoxaban and rivaroxaban in Chinese population with the age range from 18 to 80 years who take edoxaban or rivaroxaban to treat their cerebral venous thrombosis (CVT). The main question it aims to answer are: * Do cerebral veins or venous sinuses recanalize during the treatment period of edoxaban and rivaroxaban? * Do the bleeding events occur during the treatment period of edoxaban and rivaroxaban? The main tasks participants will be asked to do: * Participants will comply fully with the prescribed regimen and take the edoxaban or rivaroxaban as directed at the specified dosage. * Participants will return to hospital for scheduled follow-up assessments at months 3, 6, 9, and 12 post-enrollment to undergo face-to-face visits with investigators.

Imapct of bioMarkers on Pharmacodynamics and Bleeding Risk of Direct Oral AntiCoagulants and Ticagrelor Study II

Individual differences in drug efficacy and adverse reactions are common in the clinical application of drugs. Individual differences are caused by many factors, among which genetic factors account for more than 20%. Novel oral anticoagulant drugs (NOACs, including rivaroxaban, apixaban, edoxaban, dabigatran, etc.) and novel antiplatelet drug ticagrelor have the advantages of convenient use and no need for monitoring. But novel oral antithrombotic drugs also increase the risk of bleeding, and there is currently a lack of effective antagonists when antithrombosis is excessive or emergency surgery is required. At present, there are few studies on the causes of individual differences in novel antithrombotic drugs, and there is a lack of predictable biomarkers or drug genotypes, especially in China. Therefore, on the basis of previous studies on NOACs and ticagrelor individualized medication cohorts, this study plans to establish a validation cohort for novel antithrombotic drugs bleeding related biomarkers, conduct multi-omics testing and long-term follow-up, and explore markers related to pharmacodynamics of antithrombotic drugs, adverse bleeding reactions and clinical outcomes.
