NCT04482842

Brief Summary

This study will explore the effect of warfarin gene polymorphism on the effectiveness and safety of anticoagulant therapy in patients with acute ischemic stroke, and clarify the correlation between genetic testing and compliance rate of INR value. It will illustrate the significance of gene-guided warfarin for administered dose to anticoagulation therapy in patients with acute ischemic stroke. Then it will establish and verify a warfarin stable dose prediction model suitable for such patients, and provide basis for the personalized medication regimen of warfarin in patients with acute ischemic stroke.

Outcome Measures

Primary Outcomes (1)

  • Stroke recurrence rate, compliance rate of INR value

    Evaluation and analysis of the stroke recurrence rate and compliance rate of INR value at 12 months after treatment

    12 months

Study Arms (2)

Gene-guided Warfarin

EXPERIMENTAL
Device: Gene detection (CYP2C9*3, VKORC1)Drug: Warfarin Sodium

Routine use

OTHER
Drug: Warfarin Sodium

Interventions

Warfarin is administered at the recommended dose by detecting CYP2C9\*3 and VKORC1 gene polymorphismsand. The doctor adjusts the dosage according to the fluctuation of INR value in time.

Gene-guided Warfarin

Warfarin is administered at a gene-guided dose or at a regular dose.

  • No anticoagulation treatment in the past 10 days
  • Agree to participate in this project

You may not qualify if:
