Abstract Over the last 10 years since the introduction of non-vitamin K antagonist oral anticoagulants (NOACs) into routine clinical practice our experience with these drugs has increased tremendously, also in the context of patients undergoing electrophysiology procedures. While some open questions remain, the available evidence indicates that for the majority of cases, these interventions can safely be performed on NOACs if study-based standard operating procedures are in place and followed. This review summarizes the most current trial evidence and guidelines on the use of NOACs for patients undergoing cardioversion, atrial fibrillation ablation, and device implantations, based on previous work of the author and others.

SummaryWorldwide there is a tremendous need for affordable anticoagulants that do not require monitoring. The advent of the non-warfarin oral anticoagulant drugs represents a major advance for stroke prevention in atrial fibrillation (AF). The objectives of this review are to 1) identify gaps in our current knowledge regarding use of these single target anticoagulant drugs; 2) outline the potential implications of these gaps for clinical practice, and thereby, 3) highlight areas of research to further optimise their use for stroke prevention in AF.

Abstract Background Dose adjustment of non-vitamin K antagonist oral anticoagulants (NOACs) is indicated in some patients with atrial fibrillation (AF), based on selected patient factors or concomitant medications. Purpose We assessed the frequency of label adherence of NOAC dosing among AF patients and the associations between off-label NOAC dosing and clinical outcomes in real-world clinical practice. Methods We evaluated 53,649 AF patients treated with a NOAC using Korean National Health Insurance Service database during the period from January 2013 to December 2016. NOAC doses were classified as either underdosed or overdosed, consistent with U.S. Food and Drug Administration labeling. Cox proportional hazards regression was performed to investigate the effectiveness and safety outcomes including stroke or systemic embolism, major bleeding, and all-cause mortality. Results Overall, 16,757 NOAC-treated patients (31.2%) were underdosed, 4,492 were overdosed (8.4%), and 32,400 (60.4%) were dosed appropriately according to drug labeling. Compared with patients with label adherence, those who were underdosed or overdosed were older (71±8 and 75±7 years of age vs. 70±9 years of age, respectively; p<0.001), more likely female (39% and 53% vs. 38%, respectively; p<0.001), and had higher CHA2DS2-VASc scores (4.6±1.7 and 5.3±1.7 vs. 4.5±1.8, respectively; p<0.001). NOAC overdosing was associated with increased risk for stroke or systemic embolism (5.76 vs. 4.03 events/100 patient-years, p<0.001), major bleeding (4.77 vs. 2.94 events/100 patient-years, p<0.001), and all-cause mortality (5.43 vs. 3.05 events/100 patient-years, p<0.001) compared with label-adherent use. Figure 1 Conclusion In routine clinical practice, a significant proportion (almost 2 in 5) of AF patients received NOAC doses inconsistent with drug labeling. NOAC overdosing is associated with increased risk for stroke or systemic embolism, major bleeding, and all-cause mortality in Asian patient with AF.

Atrial fibrillation and non-vitamin K antagonist oral anticoagulants: from clinical trials to real-world clinical practice. For decades, vitamin K antagonists (VKAs) were the only oral anticoagulants available for the prevention of thromboembolism in patients with atrial fibrillation (AF). Since 2012, non-vitamin K antagonist oral anticoagulants (NOACs) are available for this indication, which have proven to be at least as effective and safe as VKAs in randomized controlled trials (RCTs). NOACs have additional benefits, such as a fast onset of action, a fixed-dose regimen without requiring regular monitoring, less interactions and less intracranial bleeding. Their emergence has caused a paradigm shift in anticoagulation therapy, with NOACs being the anticoagulant of choice compared to VKAs. Since strict in- and exclusion criteria were used in the pivotal RCTs, concerns have risen regarding the generalizability of these results to real-life clinical practice in patients with multiple comorbidities. In this manuscript, this extrapolation is discussed, focusing on 4 different topics regarding appropriate NOAC use: the management of AF patients with a single stroke risk factor, the importance of an optimal therapy adherence, potential drug-drug interactions with NOACs and addressing a geriatric AF patient after a fall. Hopefully, this manuscript will help guide clinicians in the optimal use of NOACs in their daily clinical practice.
