Abstract Background Non-vitamin‑K oral anticoagulants (NOACs) are recommended as the first-choice therapy for stroke prevention in patients with non-valvular atrial fibrillation (AF). However, the lack of monitoring may impact patients’ adherence, and non-adherence to medication is a potential hazard to safe and efficacious use. This is the first report with a ‘comparative patient-oriented perspective’ regarding the use of anticoagulant medication in the NOACs era. Our aim was to compare patients’ self-reported practical problems, adverse events and non-adherence to anticoagulation therapy. Methods A survey was conducted among patients with AF on either NOACs or vitamin‑K antagonists (VKAs). The outcomes were self-reported non-adherence to anticoagulant medication, and patients’ experiences, adverse events and practical problems correlated with the intake of the drug itself. Results A total of 765 patients filled out the questionnaire, of which 389 (50.9%) were on VKAs and 376 (49.1%) on NOACs. Age (70.6 ± 8.8 vs 70.3 ± 9.1 years) and male gender (70.4% vs 64.6%) were similar in the two groups. A significantly higher proportion of VKA users than NOAC users reported having frequent (16.2% vs 3.7%, p > 0.001) or occasional (4.1% vs 1.3%, p > 0.001) practical issues with medication intake. Self-reported non-adherence was significantly higher (24.4% vs 18.1%, p = 0.03) among VKA users. The incidence of self-reported adverse events was similar. Conclusion Patient experiences support the current guideline recommendations for NOACs as the first-choice therapy: NOAC therapy resulted in a higher practical feasibility and better adherence when compared with VKA therapy, with a similar incidence of adverse events in both groups.

Pharmacological Cardioversion

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.

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.

Pharmacological Cardioversion

For many patients with symptomatic atrial fibrillation, cardioversion is performed to restore sinus rhythm and relieve symptoms. Cardioversion carries a distinct risk for thromboembolism which has been described to be in the order of magnitude of 1 to 3 %. For almost five decades, vitamin K antagonist therapy has been the mainstay of therapy to prevent thromboembolism around the time of cardioversion although not a single prospective trial has formally established its efficacy and safety. Currently, three new direct oral anticoagulants are approved for stroke prevention in patients with non-valvular atrial fibrillation. For all three, there are data regarding its usefulness during the time of electrical or pharmacological cardioversion. Due to the ease of handling, their efficacy regarding stroke prevention, and their safety with respect to bleeding complications, the new direct oral anticoagulants are endorsed as the preferred therapy over vitamin K antagonists for stroke prevention in non-valvular atrial fibrillation including the clinical setting of elective cardioversion.

Increased Risk

Non-vitamin K antagonist oral anticoagulants (NOACs) are currently recommended for oral anticoagulation in patients with non-valvular atrial fibrillation. In the setting, NOACs effectively prevent from stroke and systemic embolic events. In spite of the favorable safety profile of NOACs when compared with vitamin K antagonists, the use of any kind of anticoagulation is associated with an increased risk of bleeding. However, there is still a lack of direct comparisons of effectiveness and safety among NOACs. The results of indirect comparisons and meta-analyses suggest that the risk of various types of hemorrhagic complications differ among the particular NOACs. Management of bleeding in patients under NOAC therapy can be challenging because of limited availability of antidotes and the lack of routine laboratory test monitoring the NOAC anticoagulant effect. In case of life-threatening or critical site bleeding, reversal of NOAC anticoagulant activity is essential together with immediate implementation of causative treatment. Moreover, some patients on chronic NOAC therapy may require urgent surgery or invasive procedures. Specific reversal agents for NOACs have been developed, i.e. more widely available idarucizumab for the factor IIa inhibitor (dabigatran) and andexanet alfa for the factor Xa inhibitors (rivaroxaban, apixaban, edoxaban) with limited availability. This review summarizes the occurrence and management of NOAC-related bleeding complications with a particular emphasis on hematuria.

High Affinity

The limitations of vitamin K antagonists prompted the development of new oral anticoagulants that could be administered in fixed doses without routine coagulation monitoring. Focusing on thrombin and factor Xa because of their prominent roles in coagulation, structure-based design led to the development of small molecules that bind to the active site pockets of these enzymes with high affinity and specificity. Four non-vitamin K antagonist oral anticoagulants are now licensed: dabigatran, which inhibits thrombin, and rivaroxaban, apixaban, and edoxaban, which inhibit factor Xa. In phase III randomized clinical trials that included over 100,000 patients these agents have proven to be at least as effective as vitamin K antagonists for prevention of stroke in patients with non-valvular atrial fibrillation and for treatment of venous thromboembolism, and to produce less bleeding, particularly less intracranial bleeding.

Abstract Background We aimed to compare effectiveness and safety of non-vitamin K antagonist oral anticoagulants (NOACs) versus vitamin-K antagonists (VKA) in atrial fibrillation (AF) patients with chronic kidney disease (CKD) not receiving dialysis. Methods By using personal identification numbers, we cross-linked individual-level data from Danish administrative registries. We identified every citizen with a prior diagnosis of AF and CKD who initiated NOAC or VKA (2011–2017). An external analysis of 727 AF patients with CKD (no dialysis) was performed to demonstrate level of kidney function in a comparable population. Study outcomes included incidents of stroke/thromboembolisms (TEs), major bleedings, myocardial infarctions (MIs), and all-cause mortality. We used Cox proportional hazards models to determine associations between oral anticoagulant treatment and outcomes. Results Of 1560 patients included, 1008 (64.6%) initiated VKA and 552 (35.4%) initiated NOAC. In a comparable population we found that 95.3% of the patients had an estimated glomerular filtration rate (eGFR) < 59 mL/min. Patients treated with NOAC had a significantly decreased risk of major bleeding (hazard ratio (HR): 0.47, 95% confidence interval (CI): 0.26–0.84) compared to VKA. There was not found a significant association between type of anticoagulant and risk of stroke/TE (HR: 0.83, 95% CI: 0.39–1.78), MI (HR: 0.45, 95% CI: 0.18–1.11), or all-cause mortality (HR: 0.99, 95% CI: 0.77–1.26). Conclusion NOAC was associated with a lower risk of major bleeding in patients with AF and CKD compared to VKA. No difference was found in risk of stroke/TE, MI, and all-cause mortality.
