Abstract Background Older patients with atrial fibrillation (AF) have a higher thromboembolic and hemorrhagic risk, however oral anticoagulation (OAC) continues to be underutilized. Purpose To analyze the use of direct oral anticoagulant (DOAC) in patients older than 80 years. Methods The REFLEJA study is a single-centre prospective observational registry including 1039 consecutive outpatients with nonvalvular AF. Results Among ≥80 years patients (n=376) there were more women (57.7% vs 41.5%; p<0.001), permanent AF (66.5 vs 42%; <0.001), heart failure (HF) (29.8 vs 20.2%, p<0.001) and vascular disease (19.7 vs 12.8%, p=0.003), although without differences in bleeding (5.9 vs 3,8%, p=0.12) and previous strokes (9.3 vs 7.1%, p=0.20). Despite a higher CHA2DS2-VASc score (4.4±1.1 VS 2.9±1.6, p<0.001), HASBLED score >2 (34.6 vs. 23.7%; p<0.001) and chronic kidney disease (CKD) (51.5 vs. 22.6%, p<0.001), total use of OAC was higher among those older (94.9% vs 90%, p=0.005). There were no differences in the prescription of DOAC (64.1% vs 69.3%, p=0.08), although lower doses (45.8 vs. 12.2%, p<0.005) were more frecuent among older patients. In multivariate analysis, HF (OR 0.60, CI 0.40–0.90; p=0.013) and CKD (OR 0.55, CI 0.41–0.76; p<0.001) were independent risk factors for the prescription of DOAC, but not age ≥80 years (OR 1.16, CI 0.58–2.31, P=0.67). Baseline characteristics Total <80 years ≥80 years p value Hypertension (%) 81.5 77.9 88 <0.001 Diabetes mellitus (%) 26.3 25.7 26.7 0.71 Malignancy (%) 6.6 6.5 6.9 0.78 Coronary artery disease (%) 12.1 10.8 14.4 0.08 Anemia (%) 16.3 12.5 23.2 <0.001 DOAC (%) 67.6 69.3 64.1 0.08 Low doses DOAC (%) 15.9 12.2 45.8 <0.001 CHA2DS2-VASc score 3.4±1.6 2.9±1.6 4.4±1.1 <0.001 HAS-BLED score 1.2±0.8 1.1±0.8 1.4±0.7 <0.001 Glomerular filtration rate (ml/min) 70.9±24.9 76.2±23.1 61.5±25 <0.001 Antiarrhythmic treatment (%) 7.3 9.6 3.1 0.005 Permanent AF 50.5 41.7 66.2 <0.001 DOAC: direct oral anticoagulants; HAS-BLED score: without INR lability; AF: atrial fibrillation. Conclusion The proportion of elderly anticoagulated patients in our environment is very high and advanced age was not associated with a lower use of DOAC.

Aim. To study the frequency of prescribing antithrombotic agents in patients with non-valvular atrial fibrillation (AF) who were hospitalized in the cardiology department of a multidisciplinary hospital.Material and methods. A retrospective one-time study of medical records of 765 patients with non-valvular AF treated in the cardiology department of a multidisciplinary hospital in 2012 and 2016 was performed.Results. All patients were stratified in three groups depending on the CHA2DS2-VASc score. The frequency of prescribing antithrombotic agents was evaluated in each group. A low risk of thromboembolic complications was found in 1% (n=3) of patients in 2012 and 0.6% (n=3) in 2016. All these patients received antithrombotic agents. CHA2DS2-VASc=1 was found in 6% (n=15) of patients with AF in 2012 and in 3.4% (n=17) in 2016. A significant number of patients in this group received anticoagulant therapy with vitamin K antagonists (warfarin) or with direct oral anticoagulants. A high risk of thromboembolic complications (CHA2DS2-VASc≥2) was found in 93% of patient (n=245) in 2012 and in 96% (n=482) in 2016. Anticoagulant therapy was prescribed in 70.2% (n=172) patients with high risk in 2012 and 80% (n=387) in 2016. However, some patients with high risk of thromboembolic complications did not have the necessary therapy.Conclusion. Positive changes in the structure and frequency of prescribing anticoagulant drugs in patients with AF and a high risk of thromboembolic complications were found during the years studied.

Atrial fibrillation (AF) is the most common arrhythmia in chronic kidney disease (CKD), with a close bidirectional relationship between the two entities. The presence of CKD in AF increases the risk of thromboembolic events, mortality and bleeding. Vitamin K antagonists (VKA) have been the mainstay of treatment for the prevention of thromboembolic events in AF until recently, with confirmed benefits in AF patients with stage 3 CKD. However, the risk-benefit profile of VKA in patients with AF and stages 4–5 CKD is controversial due to the lack of evidence from randomized controlled trials. Treatment with VKA in CKD patients has been associated with conditions such as poorer anticoagulation quality, increased risk of bleeding, faster progression of vascular/valvular calcification and higher risk of calciphylaxis. Direct oral anticoagulants (DOACs) have shown equal or greater efficacy in stroke/systemic embolism prevention, and a better safety profile than VKA in post-hoc analysis of the pivotal randomized controlled trials in patients with non-valvular AF and stage 3 CKD, yet evidence of its risk-benefit profile in more advanced stages of CKD is scarce. Observational studies associate DOACs with a good safety/effectiveness profile compared to VKA in non-dialysis CKD patients. Further, DOACs have been associated with a lower risk of acute kidney injury and CKD development/progression than VKA. This narrative review summarizes the evidence of the efficacy and safety of warfarin and DOACs in patients with AF at different CKD stages, as well as their effects on renal function, vascular/valvular calcification and bone health.

The use of direct oral anticoagulants minimized the risks associated with vitamin K antagonist (warfarin) therapy. Currently, direct oral anticoagulants have priority over warfarin for the prevention of thromboembolic events in patients with atrial fibrillation and a number of other conditions requiring anticoagulant therapy. Direct oral anticoagulants along with antiarrhythmic therapy are the accepted strategy for atrial fibrillation treatment. At the same time, the effect of drug-drug interactions (DDI) between direct oral anticoagulants and antiarrhythmic drugs, which have common points of metabolic application, has not been fully elucidated. In order to provide effective and safe anticoagulant and antiarrhythmic therapy in patients with AF, it is important to understand the mechanisms and severity of DDI of direct oral anticoagulants and antiarrhythmic agents. This review discusses the issues of DDI of direct oral anticoagulants and antiarrhythmic drugs used to treat atrial fibrillation.

This publication is devoted to the tactics of management of patients with atrial fibrillation during the pandemic of new coronavirus infection (COVID-19). Among the key issues of relevance during this period, we thought it possible to consider the epidemiology, prevalence, and pathophysiological mechanisms of atrial fibrillation in patients with COVID-19, as well as treatment strategies with regard to obvious hospitalization, rhythm control/restoration and prevention of thromboembolic events. A separate issue is the tactics regarding the prescription or continuation of therapy aimed at the prevention of thromboembolic events and possible drug interactions in patients treated for COVID-19 and receiving anticoagulant therapy with direct oral anticoagulants for atrial fibrillation.

Abstract Background Direct oral anticoagulants (DOACs) are presented as a good option for older patients owing to their safety profile. However, the dosing can become challenging especially in this population. Objective Our aim is to evaluate the predictors of inappropriate dosing of DOACs. Methods The authors analyzed the use of DOACs in 726 patients aged ≥90 years with a diagnosis of atrial fibrillation (AF) from a retrospective multicenter registry from 3 health areas in Spain. We studied the dosing, differentiating between appropriate dose, underdosing or overdosing. To evaluate the best predictive model, the Akaike information criterion (AIC) was used. Results Follow-up was 27.7±18.3 months. Mean age was 93.0±5.2 years, and 60.1% of patients were female. 339 patients received rivaroxaban (47.3%), 237 apixaban (33.1%), 105 dabigatran (14.7%) and 35 edoxaban (4.9%). An important proportion of patients received a suboptimal dose (41.5%, n=297): 35.3% underdosed and 6.1% overdosed. The rate of suboptimal dosing was higher for apixaban and lower for dabigatran (Figure 1A). In our registry we found as a predictors of inappropriate dosing: kidney function (Chronic Kidney Disease Epidemiology Collaboration), odds Ratio (OR) 1.04; 95% CI: 1.03–1.05, P&lt;0.001; weight measured in kilograms, OR 1.04; 95% CI: 1.01–1.07, P=0.012; and high blood pressure (HBP), OR 1.61; 95% CI: 1.02–2.53, P=0.041 (Figure 1B). Other variables such as HASBLED, CHADSVASc, anemia, prior bleeding, or concomitant use of antiplatelet therapy, were not significantly associated. Conclusions We want to highlight that the use of an inappropriate dose of DOAC in older patients is common, about 40% in our study. Apixaban was the most frequently underdosed DOAC. HBP, weight, and kidney function were associated with an inappropriate dosing prescription. Therefore, it is important to carefully evaluate the characteristics of the patient to prescribe the appropriate dose that guarantees a correct action.
