How to define the relative contraindications to oral anticoagulant therapy

There is currently a lack of consensus on which anticoagulant therapy contraindications should be considered "absolute" and which should be considered "relative". Guidelines do not clearly identify absolute and relative contraindications to anticoagulant therapy. Recent guidelines on AF of the European Society of Cardiology underline the relevance of several factors and their use in scores, leaving anyway space to the clinical judgment of the physician. A high bleeding risk score should generally not result per se in a contraindication to anticoagulant therapy. Rather, bleeding risk factors should be identified and treatable factors corrected. A combined use of a more hierarchical classification of the different bleeding risk factors and the risk scores probably represents the best approach to maximize the benefit of anticoagulant therapy in various clinical settings.
