The Study of Monitoring and Dosing Guidance of Direct Oral Anticoagulants Based on Pharmacokinetics, Pharmacodynamics, and Pharmacogenomics
1. Integrate pharmacokinetic-pharmacodynamic (PK-PD) modeling and pharmacogenomics techniques to develop a population PK-PD model, aiming to explore monitoring and dose guidance schemes for Direct Oral Anticoagulants (DOACs). 2. Investigate the factors influencing PK-PD of DOACs in the pulmonary embolism population, clarifying the correlation between genotype characteristics and clinical outcomes. 3. Explore the correlation between drug concentrations, coagulation indices, and clinical outcomes of DOACs, defining the indications for DOACs testing and the overall monitoring process.
• Adult patients with acute symptomatic pulmonary embolism objectively diagnosed by imaging (with or without deep vein thrombosis) who have completed anticoagulation for the acute phase and have entered the maintenance phase of anticoagulation
• Expected lifespan greater than 3 months
• Eligible for the use of Xa factor inhibitors;
• Agreement to participate in the study, signing of informed consent, and commitment to regular follow-up.
