Thromb Haemostasis
-
Patients who receive long-term oral anticoagulant (OAC) therapy often require interruption of OAC for an elective invasive procedure. Current guidelines allow bridging therapy with either unfractionated heparin (UFH) or low-molecular-weight heparin (LMWH). Apart from the risk of embolism, bleeding is an important complication in this setting and the optimal perioperative management of such patients is still under discussion. ⋯ Guideline recommendations were followed in only 31% of cases. Importantly, 69% of patients with AF were over-treated while 51% of patients with heart valve replacement were under-treated with LMWHs. A HASB-BLED score ≥ 3 was highly predictive of bleeding events.
