Preference for oral anticoagulation therapy for patients with atrial fibrillation in Europe in different clinical situations: results of the European Heart Rhythm Association Survey.

The purpose of this European Heart Rhythm Association Survey was to assess the clinical practice in relation to the use of oral anticoagulation therapy for patients with atrial fibrillation (AF) in Europe. Of special interest were patients undergoing percutaneous coronary intervention (PCI), cardioversion procedures, catheter ablation, surgery, and those suffering from anticoagulation-related bleeding. Of 38 responding centres, non-vitamin K antagonist oral anticoagulants (NOACs) were used for stroke prophylaxis and were preferred (33.3%) or considered equal (48.5%) to vitamin K antagonists (VKAs). Only 3% did not use NOACs at all. There were some practice differences regarding the use of NOACs in combination with dual antiplatelet therapy in AF patients undergoing PCI, and only 12% preferred using NOACs in this setting. Bare metal stents were preferred rather than drug-eluting stents in AF patients at high bleeding risk. There were clear practice differences between centres regarding the use of triple therapy. Most of the major bleeding events would be handled using symptomatic and supportive measures (e.g. mechanical compression, fluid replacement, blood transfusion, prothrombin complex concentrate, or recombinant Factor VIIa). More than 80% of the centres offer either VKA or NOAC for at least 3 weeks before and after cardioversion and 70% offer either VKA or NOAC before and after AF catheter ablation. Patients treated with an NOAC were routinely re-assed in most centres.
