Aim of the study was to elucidate value of HAS-BLED and HEMORR2HAGES scales for prediction bleedings in patients receiving long-term warfarin (W) therapy.
Aim of the study was to elucidate value of HAS-BLED and HEMORR2HAGES scales for prediction bleedings in patients receiving long-term warfarin (W) therapy.
Material And Methods:
The study involved 119 patients (72 men) aged 60.9+/-9.6 years with atrial fibrillation or venous thromboembolic complications. Follow up period was 5.6 +/-3.4 years. All bleedings were categorized as 1) single bleeding with INR>4.0 during the 1st month of W therapy; 2) any single bleeding after 1st month of W therapy; 3) recurrent bleedings. CYP29 and VKORC1 (G3673A) genotypic variants were determined by PCR. Patients were divided into low (<3 points of HAS-BLED scale, n=58; <4 points.
