- Title: Clinical study of the relationship between Pharmacogenomics and warfarin dose in Chinese patients
- Drug: Warfarin
- Design: To value the accuracy of warfarin Pharmacogenomics algorithm by the algorithm calculated dose and actual dose in the Chinese patients.
- Hypothesis:Pharmacogenomic algorithm guided dose can help to predict warfarin dose in Chinese patients.
|Condition or disease||Intervention/treatment|
|Atrial Fibrillation Heart Valve Disease Pulmonary Artery Embolism||Drug: Warfarin|
- For the patients who need to use warfarin, detect the "Vitamin K epoxide reductase complex subunit 1 (VKORC1),cytochrome p450 2C9 (CYP2C9), and cytochrome p450 4F2 (CYP4F2) genotype.
- Record the demographic information: gender, age, height, and weight.
- Record drug combination, complications, and international normalized ratio (INR), liver function and kidney function or other biochemical test results.
- Put genotypes, demographic information and other clinical information into the algorithm to calculate warfarin dose for the patients, and compared with the actual dose.
|Study Type :||Observational|
|Estimated Enrollment :||1000 participants|

|Warfarin Using Group||
Prescribe warfarin to the patients who are needed.
- The accuracy of the pharmacogenomics algorithm for warfarin maintenance dose [ Time Frame: one month after the initial dose of warfarin ]The proportion of the patients whose predicted dose were within 20% of the actual maintenance dose.
