Assessing the Risk of Bleeding in Patients with non-valvular Atrial Fibrillation [AF]:
The ABC Bleeding Score
The ABC Bleeding Score
Introduction
The ABC [Age/Biomarkers/Clinical History] Score is an algorithm for the prediction of major bleeding events in an individual with Atrial Fibrillation.
The algorithm incorporates two clinical risk factors:
- Age
- History of bleeding
and three biomarkers:
- GDF-15 [Growth Differentiation Factor-15] - a marker of oxidative stress
- cTn-hs [high-sensitivity cardiac Troponin T] - a marker of myocardial injury
- Haemoglobin
See Reference Hijazi et al 2016 for further information on the algorithm and a nomogram for its application and from which the 1-year risk and 3-year risk of major bleeding can be derived.
