HAS-BLED Score for Major Bleeding Risk
Clinical factors that contribute to stroke risk and support anti-coagulation in patients with atrial fibrillation are frequently risk factors for bleeding as well. The HAS-BLED score was developed as a practical risk score to estimate the 1-year risk for major bleeding in patients with atrial fibrillation.

Additional information

Study included 5,333 ambulatory and hospitalized patients with AF from both academic and non-academic hospitals in 35 member countries of the European Society for Cardiology.
Patients were followed up at one year to determine survival and major adverse cardiovascular events, such as major bleeding.
Major bleeding defined as any bleeding requiring hospitalization, and/or causing a decrease in hemoglobin level > 2 g/L, and/or requiring blood transfusion that was not hemorrhagic stroke.
Researchers performed a retrospective, univariate analysis to find potential bleeding risk factors when comparing the groups with and without major bleeding at 1 year follow-up.
Developed HAS-BLED score based on results of their analysis as well as known significant risk factors for major bleeding
