Abstract Background A decline of estimated glomerular filtration rate (eGFR) has been described in atrial fibrillation (AF) patients on Vitamin K antagonists (VKAs). Few real-world data on the modifications of eGFR in AF patients treated with non-vitamin K antagonist oral anticoagulants (NOACs) do exist. Purpose To evaluate changes of renal function in AF patients treated with VKAs or NOACs. Methods Multicentre prospective cohort study including 1,667 patients with non-valvular AF from 5 clinical centres of Internal Medicine and Cardiology in Italy. Renal endpoints were: 1) median annual decline of eGFR; 2) transition to eGFR <50 ml/min/1.73 m2; 3) eGFR class worsening according to KDIGO 2012 classification. The eGFR was assessed by the CKD-EPI formula at baseline and during follow-up. Results Median age was 73.7±9.1 years and 43.3% were women. 743 patients were on VKAs and 924 on NOACs (Dabigatran, Rivaroxaban e Apixaban). Median annual eGFR decline was −2,11 (Interquartile Range [IQR] −5,68/−0,62] in patients on VKAs, −0,27 [IQR −9,00/4,54] with Dabigatran (p<0.001 vs. VKAs), −1,21 [IQR −9,98/4,02] with Rivaroxaban (p=0.004 vs. VKAs) and −1,32 [IQR −8,7/3,99] with Apixaban (p=0.003, vs. VKAs). Use of Dabigatran and Apixaban was associated to a lower transition to eGFR <50 mL/min/1.73 m2, compared to VKAs: adjusted Odds Ratio (aOR) 0.492, 95% Confidence Interval (CI) 0.298–0.813, p=0.006 for Dabigatran; aOR 0.449, 95% CI 0.276–0.728, p=0.001 for Apixaban). Regarding the eGFR class worsening, Dabigatran (aOR 0.70, 95% CI 0.503–0.975, p=0.035), Rivaroxaban (aOR 0.591, 95% CI 0.423–0.825, p=0.002), and Apixaban (aOR 0.591, 95% CI 0.429–0.815, p=0.001) were all associated to a lower rate of eGFR class worsening compared to VKAs. Forest plot Conclusions In this prospective multicentre cohort study, NOACs use was associated with a lower decline of renal function compared to VKAs. Patients on Dabigatran showed the lowest annual rate of eGFR decline and those on Apixaban and Rivaroxaban a lower eGFR class worsening. Acknowledgement/Funding None

The therapeutic dilemma between rhythm and rate control in the management of atrial fibrillation (AF) is still unresolved and electrical or pharmacological cardioversion (CV) frequently represents a useful strategy. The most recent guidelines recommend anticoagulation according to individual thromboembolic risk. Vitamin K antagonists (VKAs) have been routinely used to prevent thromboembolic events. Non-vitamin K antagonist oral anticoagulants (NOACs) represent a significant advance due to their more predictable therapeutic effect and more favorable hemorrhagic risk profile. In hemodynamically unstable patients, an emergency electrical cardioversion (ECV) must be performed. In this situation, intravenous heparin or low molecular weight heparin (LMWH) should be administered before CV. In patients with AF occurring within less than 48 h, synchronized direct ECV should be the elective procedure, as it restores sinus rhythm quicker and more successfully than pharmacological cardioversion (PCV) and is associated with shorter length of hospitalization. Patients with acute onset AF were traditionally considered at lower risk of thromboembolic events due to the shorter time for atrial thrombus formation. In patients with hemodynamic stability and AF for more than 48 h, an ECV should be planned after at least 3 weeks of anticoagulation therapy. Alternatively, transesophageal echocardiography (TEE) to rule out left atrial appendage thrombus (LAAT) should be performed, followed by ECV and anticoagulation for at least 4 weeks. Theoretically, the standardized use of TEE before CV allows a better stratification of thromboembolic risk, although data available to date are not univocal.

Background: Non-vitamin K antagonist oral anticoagulants (NOACs) are more commonly used to prevent atrial fibrillation (AF) patients from thromboembolic events than vitamin K antagonists (VKAs). However, the gastrointestinal bleeding (GIB) risk in the Asian AF patients associated with NOACs in comparison with VKAs remained unaddressed. Materials and Methods: A systematic search of studies on NOACs and VKAs in the Asian AF patients was conducted in PubMed, Cochrane Library, and ClinicalTrials.gov. The primary outcome was the hazard ratio (HR) of any GIB associated with NOACs versus VKAs. The secondary outcome was the GIB risks in different kinds of NOACs compared with VKAs. Results: This meta-analysis included two randomized controlled trials (RCTs) and four retrospective studies, comprising at least 200,000 patients in total. A significantly lower HR of GIB risks was found in all kinds of NOACs than VKAs in the Asian AF patients (HR: 0.633; 95% confidence interval: 0.535–0.748; p < 0.001). Additionally, the GIB risks of different NOACs were apixaban (HR: 0.392), edoxaban (HR: 0.603), dabigatran (HR: 0.685), and rivaroxaban (HR: 0.794), respectively. Conclusions: NOACs significantly reduced the risk of GIB in the Asian AF patients compared with VKAs. In the four NOACs compared with VKAs, apixaban probably had a trend of the least GIB risk. We need further head-to-head studies of different NOACs to confirm which NOAC is the most suitable for Asian AF patients and to know the optimal dosage regimen of different NOACs.

Abstract Background New direct oral anticoagulants (NOACs), as a preferable treatment option for acute venous thromboembolism (VTE) have been recommended with practical advantages as compared to Vitamin K antagonists (VKAs) in clinical practice. Purpose In our study, we performed a meta-analysis to determine the efficacy and safety of NOACs vs. VKAs in patients with different age, sex and renal function for the treatment of VTE. Methods Electronic databases (accessed October 2019) were systematically searched to identify RCTs evaluating apixaban, dabigatran, edoxaban, and rivaroxaban versus VKAs for the treatment of acute venous thromboembolism. Results NOACs was associated with a borderline higher efficacy in female (OR 0.79, 95% CI 0.62–1.02), and a significantly higher efficacy in patients with age more than 75 (OR 0.51, 95% CI 0.32–0.80) and creatinine clearance less than 50 mL/min (OR 0.57, 95% CI 0.32–0.99). NOACs also show advantage in terms of major or clinically relevant non-major bleeding in male (OR 0.72, 95% CI 0.60–0.86), and patients with creatinine clearance more than 50 mL/min (OR 0.75, 95% CI 0.67–0.84). Conclusions NOACs have exhibited clinical preference among patients with acute VTE as compared to VKA with significantly decreased thrombosis events and lower bleeding complications, especially in patients with age more than 75 and creatinine clearance less than 50 mL/min.

Objective: To describe major events at follow up in octogenarian patients with atrial fibrillation (AF) according to anticoagulant treatment: direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs). Methods: A total of 578 anticoagulated patients aged ≥80 years with AF were included in a prospective, observational, multicenter study. Basal features, embolic events (stroke and systemic embolism), severe bleedings, and all-cause mortality at follow up were investigated according to the anticoagulant treatment received. Results: Mean age was 84.0 ± 3.4 years, 56% were women. Direct oral anticoagulants were prescribed to 123 (21.3%) patients. Compared with 455 (78.7%) patients treated with VKAs, those treated with DOACs presented a lower frequency of permanent AF (52.9% vs 61.6%, P = .01), cancer history (4.9% vs 10.9%, P = .046), renal failure (21.1% vs 32.2%, P = .02), and left ventricular dysfunction (2.4% vs 8.0%, P = .03); and higher frequency of previous stroke (26.0% vs 16.6%, P = .02) and previous major bleeding (8.1% vs 3.6%, P = .03). There were no significant differences in Charlson, CHA2DS2VASc, nor HAS-BLED scores. At 3-year follow up, rates of embolic events, severe bleedings, and all-cause death (per 100 patients-year) were similar in both groups (DOACs vs VKAs): 0.34 vs 1.35 ( P = .15), 3.45 vs 4.41 ( P = .48), and 8.2 vs 11.0 ( P = .18), respectively, without significant differences after multivariate analysis (hazard ratio [HR]: 0.25, 95% confidence interval [CI]: 0.03-1.93, P = .19; HR: 0.88, 95% CI: 0.44-1.76, P = .72 and HR: 0.84, 95% CI: 0.53-1.33, P = .46, respectively). Conclusion: In this “real-world” registry, the differences in major events rates in octogenarians with AF were not statistically significant in those treated with DOACs versus VKAs.
