简要总结

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.

结局指标

主要结局

Incidence of new thromboembolic events

时间窗: From 1 year to 2 years after enrollment

During the observation time, record the incidence of new thromboembolic events after NOACs(rivaroxaban, apixaban, edoxaban, dabigatran) or ticagrelor administration by telephone and out-patient clinic, including stroke or TIA, systemic embolism (SE), deep vein thrombosis (DVT), pulmonary embolism, left auricular thrombus, stent thrombosis, stent stenosis and stent endothelial hyperplasiastent, etc.

Incidence of new bleeding events

时间窗: From 1 year to 2 years after enrollment

During the observation time, record the incidence of new bleeding events after NOACs(rivaroxaban, apixaban, edoxaban, dabigatran) or ticagrelor administration by telephone and out-patient clinic, including subcutaneous bleeding, gingival bleeding, gastrointestinal bleeding, intracranial hemorrhage, etc.

Incidence of new major cardiovascular events and all-cause death

时间窗: From 1 year to 2 years after enrollment

During the observation time, record the new incidence of major cardiovascular events (MACEs) and all-cause death after NOACs(rivaroxaban, apixaban, edoxaban, dabigatran) or ticagrelor administration by telephone and out-patient clinic. MACEs including cardiac death, myocardial infarction (MI), stroke or transient cerebral thrombus (TIA), ischemic-driven coronary revascularization(PCI, CABG, thrombolysis, etc.), etc.

次要结局

  • Genotype detected by next generation sequencing(Through study completion, collection only once)
  • Expression level of RNA in platelet and white blood cell(NOACs: Once each before administration, before and after administration at stable concentration (at least 48h for rivaroxaban, 72h for apixaban or edoxaban). Ticagrelor: Once before administration and once after stable concentration (at least 48h).)
  • Anticoagulantion activity evaluation (for NOACs only)(Once each before administration, before and after administration at stable concentration (at least 48h for rivaroxaban, 72h for apixaban or edoxaban) .)
  • Platelet reactivity evaluation (for Ticagrelor only)(Once before administration and once after stable concentration.)
