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.

Real World Data

Background and purposeReal-world data about treatment convenience and satisfaction in Asian non-valvular atrial fibrillation (NVAF) patients after switching from vitamin K antagonists (VKAs) to non-VKA oral anticoagulants were evaluated.MethodsIn this non-interventional study involving 49 sites across five countries in Southeast Asia and South Korea, 379 stable NVAF patients who switched from VKA therapy to dabigatran during routine clinical practice were recruited and followed up for 6 months. Treatment convenience and satisfaction were evaluated using Perception on Anticoagulant Treatment Questionnaire-2 (PACT-Q2). Through post hoc analysis, factors associated with improved treatment convenience scores at visit 2 were described.ResultsTreatment convenience and satisfaction significantly improved after switching from VKAs to dabigatran at visit 2 and visit 3 (convenience: p<0.001 each vs baseline; satisfaction: p=0.0174 (visit 2), p=0.0004 (visit 3) compared with baseline). Factors predictive of higher (>80th percentile) response on treatment convenience were female sex, younger age (<75 years), higher baseline stroke risk, higher creatinine clearance and absence of concomitant hypertension, stroke or gastrointestinal diseases.ConclusionDabigatran was associated with a significant improvement in treatment convenience and satisfaction after switching from VKAs when used for stroke prevention in NVAF patients from Southeast Asia and South Korea.

Aim. To evaluate the efficacy and safety of direct oral anticoagulants (DOACs) in patients with atrial fibrillation (AF) and stages I-III chronic kidney disease (CKD). Subjects and methods. The cohort parallel-group study included 92 patients with AF and stages I-III diabetic and non-diabetic CKD, who were treated with DOACs (dabigatran, rivaroxaban, or apixaban) and vitamin K antagonists (warfarin). The follow-up duration was 12 months. Results. Thromboembolic events and bleeding, which required patient hospitalization or blood transfusions, were not recorded during 1-year follow-up. There was no clinically significant progression of CKD in the groups of therapy with vitamin K antagonists or DOACs. Just the same, a more intense decrease in glomerular filtration rate and a high rate of hemorrhagic complications were revealed in the subgroup of patients with diabetes mellitus (DM) versus those with non-diabetic CKD. Conclusion. In patients with non-valvular AF and diabetic and non-diabetic CKD, the use of DOACs effectively and safely prevents thromboembolic events, irrespective of the stage of CKD. At the same time, in patients taking anticoagulants, CKD progresses more rapidly in the presence of DM than in its absence, regardless of a specific anticoagulant. Hemorrhagic complications are more common in patients with AF, DM, and CKD, which requires more frequent monitoring of their kidney function.

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.

Clinical Variants

Non-vitamin K antagonist oral anticoagulants (NOACs) – direct oral anticoagulants – are getting the ever-broadening use in clinical practice. However, many problems related to optimal use of NOACs in specific clinical situations remain unresolved. European Heart Rhythm Association in April 2018 issued the renovated recommendations on the use of NOACs in patients with atrial fibrillation. The authors of recommendations presented some specific clinical variants for which they formulated practical advices based on the evidence obtained in randomized clinical trials. They also outlined the indications for use of NOACs, formulated practical start-program and scheme of subsequent follow-up management of patients taking NOACs. Recommendations contain information on pharmacokinetics of NOACs and their interactions with other drugs, consideration of feasibility of NOACs use in patients with chronic renal insufficiency or advanced liver disease. Many other practical problems are covered as well.

Introduction and Objective: Even though the introduction of less cumbersome anticoagulant agents has improved, the rates ofoverall anticoagulant treatment in eligible patients with atrial fibrillation (AF) remain to be defined. We aimed to assess the rates of and determinants for the use of anticoagulation treatment before stroke in patients with known AF since the introduction of direct oral anticoagulants (DOAC) in clinical practice. Methods: Consecutive patients admitted to an individual stroke unit, from September 2013 through July 2019, for acute ischemic stroke or transient ischemic attack (TIA) with known AF before the event were included in the study. Logistic regression analysis was used to identify independent predictors of the use of anticoagulant treatment. Results: Overall, 155 patients with ischemic stroke/TIA and known AF were included in this study. Among 152 patients with a CHA2DS2-VASc score >1, 43 patients were not receiving any treatment, 47 patients were receiving antiplatelet agents, and the remaining 62 patients were on oral anticoagulants. Among 34 patients on DOAC, 13 were receiving a nonlabeled reduced dose and 18 out of 34 patients on vitamin K antagonists had an INR value <2 at the time of admission. Before stroke, only 34 out of 155 patients (21.9%) were adequately treated according to current guidelines. Previous stroke/TIA was the only independent predictor of the use of anticoagulant therapy. Conclusions: Only 21.9% of the patients hospitalized for a stroke or TIA with known AF before the event were adequately treated according to recent treatment guidelines. It is important to improve medical information about the risk of AF and the efficacy of anticoagulants in stroke prevention.

Efficacy And Safety

Abstract Background Direct oral anticoagulants (DOACs) are recommended as first-line anticoagulants in patients with atrial fibrillation (AF). However, in patients with cancer and AF the efficacy and safety of DOACs are not well established. Objective We performed a meta-analysis comparing available data regarding the efficacy and safety of DOACs vs vitamin K antagonists (VKAs) in cancer patients with non-valvular AF. Methods An online search of Pubmed and EMBASE libraries (from inception to May, 1 2020) was performed, in addition to manual screening. Nine studies were considered eligible for the meta-analysis involving 46,424 DOACs users and 182,797 VKA users. Results The use of DOACs was associated with reduced risks of systemic embolism or any stroke (RR 0.65; 95% CI 0.52–0.81; p 0.001), ischemic stroke (RR 0.84; 95% CI 0.74–0.95; p 0.007) and hemorrhagic stroke (RR 0.61; 95% CI 0.52–0.71; p 0.00001) as compared to VKA group. DOAC use was associated with significantly reduced risks of major bleeding (RR 0.68; 95% CI 0.50–0.92; p 0.01) and intracranial or gastrointestinal bleeding (RR 0.64; 95% CI 0.47–0.88; p 0.006). Compared to VKA, DOACs provided a non-statistically significant risk reduction of the outcomes major bleeding or non-major clinically relevant bleeding (RR 0.94; 95% CI 0.78–1.13; p 0.50) and any bleeding (RR 0.91; 95% CI 0.78–1.06; p 0.24). Conclusions In comparison to VKA, DOACs were associated with a significant reduction of the rates of thromboembolic events and major bleeding complications in patients with AF and cancer. Further studies are needed to confirm our results.
