Antiphospholipid Syndrome Diagnosed as a Result of the Occurrence of an Ischemic Stroke After a Successful Catheter Ablation of Atrial Fibrillation and Continuous Direct Oral Anticoagulants
We report a case of an ischemic stroke after a successful catheter ablation of atrial fibrillation (AF) and continuous oral anticoagulation therapy with direct oral anticoagulants (DOACs), which was the trigger for diagnosing antiphospholipid syndrome (APS). A 68-year-old woman underwent catheter ablation of persistent AF and continued oral anticoagulation with edoxaban at a dose of 30 mg once daily after the ablation procedure. An asymptomatic intracerebral hemorrhage was detected by brain computed tomography and magnetic resonance imaging one month post-ablation. Oral anticoagulation with dabigatran at 110 mg twice daily...

Severe Bleeding Risk of Direct Oral Anticoagulants Versus Vitamin K Antagonists for Stroke Prevention and Treatment in Patients with Atrial Fibrillation: A Systematic Review and Network Meta-Analysis
ConclusionBased on current evidence, for stroke prevention and treatment in patients with AF, the most safe DOAC is edoxaban in terms of fatal bleeding; dabigatran in terms of major bleeding and intracranial hemorrhage and apixaban in terms of gastrointestinal bleeding. However, given the nature of indirect comparisons, more high-quality evidence from head-to-head comparisons is still needed to confirm them.

Dabigatran and warfarin for secondary prevention of stroke in atrial fibrillation patients: A nationwide cohort study
This study revealed, that in clinical practice, vitamin K antagonist-experienced patients with a history of stroke or transient ischemic attack who switch to dabigatran therapy may have an increased rate of a recurrent stroke compared to patients persisting with vitamin K antagonist therapy.

Systematic review and network meta-analysis comparing antithrombotic agents for the prevention of stroke and major bleeding in patients with atrial fibrillation
Conclusions Compared with standard adjusted dose VKA, new oral anticoagulants were associated with modest reductions in the absolute risk of stroke and major bleeding. People on antiplatelet drugs experienced more strokes compared with anticoagulant drugs without any reduction in bleeding risk. To fully elucidate the comparative benefits and harms of antithrombotic agents across the various subpopulations, rigorously conducted comparative studies or network meta-regression analyses of patient-level data are required. Systematic review registration number PROSPERO registry—CRD42012002721.

Efficacy and Harms of Direct Oral Anticoagulants in the Elderly for Stroke Prevention in Atrial Fibrillation and Secondary Prevention of Venous Thromboembolism: Systematic Review and Meta-Analysis.
CONCLUSIONS: -DOACs demonstrated at least equal efficacy to VKA in managing thrombotic risks in the elderly however bleeding patterns were distinct. In particular, dabigatran was associated with a higher risk of gastrointestinal bleeding than VKA. Insufficient published data for apixaban, edoxaban and rivaroxaban indicates further work is needed to clarify their bleeding risks in the elderly. PMID: 25995317 [PubMed - as supplied by publisher]

Apixaban versus edoxaban for stroke prevention in nonvalvular atrial fibrillation.
Authors: Xiong Q, Lau YC, Lip GY Abstract Oral anticoagulation therapy is the mainstay of stroke prevention in nonvalvular atrial fibrillation patients. Vitamin K antagonists (such as warfarin) have been effective conventional oral anticoagulants for several decades. However, due to their limitations in clinical use, several nonvitamin K antagonist oral anticoagulants (NOACs, including dabigatran, rivaroxaban, apixaban and edoxaban) have been developed. Nonetheless, no head to head trials have been performed to directly compare these NOACs in patient cohorts. In this review article, two direct factor Xa inhibitors,...

Stroke Prevention in Atrial Fibrillation: A Clinical Perspective on Trials of the Novel Oral Anticoagulants
This article summarizes phase III data in patient subtypes and discusses controversies surrounding AF management with these agents. Results indicate that NOACs in non-valvular AF have an overall improved efficacy–safety profile compared with warfarin. Significantly fewer fatal bleeding events were observed in patients randomized to rivaroxaban, apixaban, or edoxaban compared with those on warfarin, and significant reductions in the incidence of life-threatening bleeding were observed in patients randomized to dabigatran. All four pivotal trials testing the NOACs against warfarin showed significantly lower rates of intrac...

Cost-effectiveness of non-vitamin K antagonist oral anticoagulants for stroke prevention in non-valvular atrial fibrillation: a systematic and qualitative review.
Authors: Liberato NL, Marchetti M Abstract The introduction of non-vitamin K antagonist oral anticoagulants (NOACs) into clinical practice represented a major change in the treatment of non-valvular atrial fibrillation (NVAF); drugs as effective as the gold standard were available, rapidly functioning and without major interferences with drugs and foods. However, a huge increase in the economic burden of NVAF was predicted, and many cost-effectiveness analyses were developed to aid policy makers and clinicians in implementing strategies for the prevention of stroke in NVAF. The present systematic review identified ...

Vitamin K antagonists: relative strengths and weaknesses vs. direct oral anticoagulants for stroke prevention in patients with atrial fibrillation
This article reviews and highlights real and perceived implications of VKAs for the prevention of stroke in patients with non-valvular AF, with specific reference to their strengths and weaknesses compared with DOACs.

New frontiers in anticoagulation: non vitamin-K oral anticoagulants in stroke prevention.
Authors: Arnao V, Riolo M, Tuttolomondo A, Pinto A, Fierro B, Aridon P Abstract INTRODUCTION: Non vitamin-K oral anticoagulants (NOACs) are direct and specific inhibitors of the coagulation factors IIa (dabigatran) and Xa (apixaban, rivaroxaban, edoxaban) which share many pharmacokinetic properties. However, indications are lacking regarding the use of NOACs during thrombolysis, surgery and bleeding events. Areas covered: In this paper, the authors retrospectively analyzed the relevant literature on the NOACs using the PubMed and Google Scholar databases. Expert Commentary: Although warfarin is effective in cardioembo...

Comparison of the cost-utility of direct oral anticoagulants for the prevention of stroke in patients with atrial fibrillation in Spain.
CONCLUSIONS: All three direct anticoagulants are cost-effective against acenocoumarol. Dabigatran is economically dominant over rivaroxaban and apixaban in the Spanish setting, as it is more effective and cheaper. PMID: 28272725 [PubMed - in process]
