Show moreBackground: Prospective data on nonvitamin-K-antagonist oral anticoagulant (NOAC) management during cardiovascular interventions are limited. We therefore evaluated the safety and effectiveness of uninterrupted dabigatran therapy as well as dabigatran management during atrial fibrillation (AF)-cardioversions, AFablations, pacemaker implantations and coronary angiography and/or stenting procedures. Method: GLORIA-AF is an international registry programme involving patients with newly diagnosed AF. Dabigatran users were followed for <2 years. The primary outcome was occurrence of stroke/systemic embolism and major bleeding <8 weeks after a cardiovascular intervention during uninterrupted dabigatran therapy. Results: During the 2-year follow-up, 599 cardiovascular interventions were identified in 479 eligible patients. 412/599 (69%) interventions were performed with uninterrupted dabigatran therapy: 299/354 (84%) AFcardioversions, 38/89 (43%) AF-ablations, 25/58 (43%) pacemaker implantations, and 50/98 (51%) coronary angiography and/or stenting procedures. During an average follow-up of 8.4 weeks after intervention, one major bleed and one systemic embolic event occurred (risk 0.25% for both outcomes; 95% confidence interval, 0.01%1.36%). Conclusions: More than two thirds of the interventions were performed with uninterrupted dabigatran therapy, of which most were AF-cardioversions. Uninterrupted dabigatran therapy was associated with low major bleeding and stroke/systemic embolism risk, supporting the favourable safety and effectiveness profile of dabigatran in clinical practice-based settings.
