- Aims: Cardiac implantable electronic device (CIED) surgery is commonly performed in patients with atrial fibrillation (AF). The current analysis was undertaken to compare peri-operative anticoagulation management, bleeding, and thrombotic events in AF patients treated with dabigatran vs. warfarin.Methods and results: This study included 611 patients treated with dabigatran vs. warfarin who underwent CIED surgery during the RE-LY trial. Among 201 warfarin-treated patients, warfarin was interrupted a median of 144 (inter-quartile range, IQR: 120-216) h, and 37 (18.4%) patients underwent heparin bridging. In dabigatran-treated patients (216 on 110 mg bid and 194 on 150 mg bid), the duration of dabigatran interruption was a median of 96 (IQR: 61-158) h. Pocket hematomas occurred in 9 (2.20%) patients on dabigatran and 8 (3.98%) patients on warfarin (P = 0.218). The occurrence of pocket hematomas was lower with dabigatran compared with warfarin with heparin bridging (RD: -8.62%, 95% CI: -24.15 to - 0.51%, P = 0.034) but not when compared with warfarin with no bridging (P = 0.880). Ischemic stroke occurred in 2 (0.3%) patients; one in the warfarin group (without bridging) and one in the dabigatran 150 mg bid group (P = 0.735).Conclusion: In patients treated with dabigatran undergoing CIED surgery, interruption of dabigatran is associated with similar or lower incidence of pocket hematoma, when compared with warfarin interruption without or with heparin bridging, respectively. Whether uninterrupted dabigatran can reduce pocket hematoma or ischemic stroke remains to be evaluated.

- Aims: Data on patient characteristics, prevalence, and outcomes of atrial fibrillation (AF) patients without traditional risk factors, often labelled 'lone AF', are sparse. Methods and results: The RE-LY AF registry included 15 400 individuals who presented to emergency departments with AF in 47 countries. This analysis focused on patients without traditional risk factors, including age >= 60years, hypertension, coronary artery disease, heart failure, left ventricular hypertrophy, congenital heart disease, pulmonary disease, valve heart disease, hyperthyroidism, and prior cardiac surgery. Patients without traditional risk factors were compared with age- and region-matched controls with traditional risk factors (1:3 fashion). In 796 (5%) patients, no traditional risk factors were present. However, 98% (779/796) had less-established or borderline risk factors, including borderline hypertension (130-140/80-90mmHg; 47%), chronic kidney disease (eGFR<60mL/min; 57%), obesity (body mass index>30; 19%), diabetes (5%), excessive alcohol intake (>14 units/week; 4%), and smoking (25%). Compared with patients with traditional risk factors (n=2388), patients without traditional risk factors were more often men (74% vs. 59%, P<0.001) had paroxysmal AF (55% vs. 37%, P<0.001) and less AF persistence after 1 year (21% vs. 49%, P<0.001). Furthermore, 1-year stroke occurrence rate (0.6% vs. 2.0%, P=0.013) and heart failure hospitalizations (0.9% vs. 12.5%, P<0.001) were lower. However, risk of AF-related re-hospitalization was similar (18% vs. 21%, P=0.09). Conclusion: Almost all patients without traditionally defined AF risk factors have less-established or borderline risk factors. These patients have a favourable 1-year prognosis, but risk of AF-related re-hospitalization remains high. Greater emphasis should be placed on recognition and management of less-established or borderline risk factors.

- Oral anticoagulation (OAC) reduces stroke risk in patients with atrial fibrillation (AF). We sought to determine predictors of OAC initiation in AF patients presenting to the emergency department (ED). Secondary analysis of the RE-LY AF registry which enrolled individuals from 47 countries between 2007 and 2011 who presented to an ED with AF and followed them for 1 year. A total of 4149 patients with AF as their primary diagnosis who were not already taking OAC and had a CHA2DS2-VASc ≥ 1 for men or ≥ 2 for women were included in this analysis. Of these individuals, 26.8% were started on OAC (99.2% vitamin K antagonists) in the ED and 29.8% were using OAC one year later. Factors associated with initiating OAC in the ED included: specialist consultation (relative risk [RR] 1.84, 95%CI 1.44-2.36), rheumatic heart disease (RR 1.60, 95%CI 1.29-1.99), persistence of AF at ED discharge (RR 1.33, 95%CI 1.18-1.50), diabetes mellitus (RR 1.32, 95%CI 1.19-1.47), and hospital admission (RR 1.30, 95%CI 1.14-1.47). Heart failure (RR 0.83, 95%CI 0.74-0.94), antiplatelet agents (RR 0.77, 95%CI 0.69-0.84), and dementia (RR 0.61, 95%CI 0.40-0.94) were inversely associated with OAC initiation. Patients taking OAC when they left the ED were more likely using OAC at 1-year (RR 2.81, 95%CI 2.55-3.09) and had lower rates of death (RR 0.55, 95%CI 0.38-0.79) and stroke (RR 0.59, 95%CI 0.37-0.96). In patients with AF presenting to the ED, prompt initiation of OAC and specialist involvement are associated with a greater use of OAC 1 year later and may result in improved clinical outcomes.
