Real-world Data and Recommended Dosage of Non-vitamin K Oral Anticoagulants for Korean Patients.
Authors: Joung B Abstract Regulatory approvals of non-vitamin K antagonist oral anticoagulants (NOACs) have been based on large randomized phase III trials evaluating dabigatran, rivaroxaban, apixaban, or edoxaban relative to warfarin for atrial fibrillation (AF). The results of the trials showed that all NOACs were at least non-inferior to warfarin in the prevention of stroke/thromboembolism and showed lower rates of intracranial bleeding than those associated with warfarin. However, the trials were designed differently, varied in the inclusion/exclusion criteria, and used either one dose or a low/high dose of the...

Use of Non –Vitamin K Antagonist Oral Anticoagulants in Atrial Fibrillation Patients with Malignancy: Clinical Practice Experience in a Single Institution and Literature Review
Semin Thromb Hemost DOI: 10.1055/s-0037-1607436This observational study aimed to investigate the efficacy and safety of non–vitamin K antagonist oral anticoagulants (NOACs) in atrial fibrillation (AF) patients with malignancy. A total of 76 patients (mean age: 73.2 ± 8.9; 28 females) with AF and malignancy treated with NOAC were included in the analysis. The mean CHA2DS2-VASc and HAS-BLED scores were 3.2 ± 1.2 and 2.2 ± 0.9, respectively. The study population was taking dabigatran 150 mg (25%) twice daily (BID), apixaban 5 mg BID (25%), dabigatran 110 mg BID (24%), rivaroxaban 20 mg (18%) once a da...

Anticoagulation in geriatric patients with atrial fibrillation : With what and for whom no more?
Authors: Bahrmann P, Christ M Abstract Based on established risk scores, such as the CHA2DS2-VASc score, the indications for oral anticoagulation are given for patients over 65 years old with atrial fibrillation and even more so for patients over 75 years old. Before beginning anticoagulation a geriatric assessment for evaluation of the cognitive ability, the activities of daily living and the risk of falling should be made because of the known complications of anticoagulation. Geriatric patients with non-valvular atrial fibrillation (AF) are increasingly being treated with non-vitamin K antagonist oral anticoagul...

Reversal of Anticoagulation: Therapeutic Advances and Clinical Guidelines
Background: Anticoagulants are life-saving medications that prevent and treat thromboembolic disease and are of particular importance in the elderly population for prevention of stroke in atrial fibrillation. The advent of direct oral anticoagulants and reversal agents has yielded more options for patients, although complicating clinical decision-making. Areas of Uncertainty: The decision to anticoagulate in atrial fibrillation depends on the risks of stroke versus bleeding. The accompanying HAS-BLED score for predicting bleeding allows an estimation of net clinical benefit. Despite these tools, uncertainty remains. N...

Effectiveness and Safety of Non-Vitamin K Oral Anticoagulants in Comparison to Phenprocoumon: Data from 61,000 Patients with Atrial Fibrillation.
Abstract All pivotal trials have evaluated non-vitamin K oral antagonists (NOACs) against warfarin. However, in some regions of the world, phenprocoumon is the most widely used vitamin K antagonist (VKA). There is little evidence documenting effectiveness and safety of NOACs compared with phenprocoumon in atrial fibrillation (AF). A retrospective cohort study using a German claims database was conducted to assess effectiveness (stroke, systemic embolism [SE]) and safety (bleeding leading to hospitalization) during therapy with NOACs and phenprocoumon in 61,205 AF patients. Hazard ratios (HRs) for effectiveness and...

Fitting the right non-vitamin K antagonist oral anticoagulant to the right patient with non-valvular atrial fibrillation: An evidence-based choice.
Authors: Li Y, Pastori D, Lip GY Abstract Atrial fibrillation (AF) is the most prevalent arrhythmia and is associated with an increased risk of ischemic stroke (IS) and systemic embolism (SE). Stroke prevention is a key element for the overall management of AF patients. The non-vitamin K antagonist oral anticoagulants (NOACs), such as dabigatran, rivaroxaban, apixaban and edoxaban, are at least as effective as warfarin in reducing IS/SE with a lower rate of major bleeding. Various analyses from the large Phase III randomised trials demonstrated different efficacy and safety of NOACs in specific subgroups of patient...

Novel oral anticoagulants in chronic kidney disease: ready for prime time?
Purpose of review Patients with chronic kidney disease (CKD) are at increased risk of atrial fibrillation, stroke, and bleeding posing unique clinical challenges. Novel oral anticoagulants (NOACs) including dabigatran, rivaroxaban, and apixaban have become recognized as alternative therapy to Vitamin K Antagonists (VKA) regarding the prevention of venous thromboembolism (VTE) and reduce the risk of stroke in atrial fibrillation. However, the understanding of NOACs in CKD is still underdeveloped. This review summarizes recent literature on the efficacy and safety of NOACs in patients with CKD. Recent findings Studies f...

Direct Oral Anticoagulants in Nonvalvular Atrial Fibrillation: Practical Considerations on the Choice of Agent and Dosing
Direct or new oral anticoagulants (NOACs), including the direct thrombin inhibitor dabigatran and the direct factor Xa inhibitors rivaroxaban, apixaban, and edoxaban, have recently revolutionized the field of antithrombotic therapy for stroke and systemic embolism prevention in nonvalvular atrial fibrillation (NVAF). Randomized controlled trials have shown that these agents have at least comparable efficacy with vitamin K antagonists along with superior safety, at least in what concerns intracranial hemorrhage. As a result, NOACs are indicated as first-line anticoagulation therapy for NVAF patients with at least one risk f...

Long term outcome in patients with non-valvular atrial fibrillation on dabigatran: a prospective cohort study.
CONCLUSIONS: This prospective cohort study confirms the low incidence of stroke, major bleeding and intracranial bleeding, and a 76% persistence with treatment, in NVAF patients treated with dabigatran over about two years. PMID: 30260252 [PubMed - as supplied by publisher]

Comparative effectiveness and safety of non-vitamin K antagonist oral anticoagulants versus warfarin in non-valvular atrial fibrillation patients: The dose subgroup analysis of the ARISTOPHANES study
ConclusionsIn this large observational study, api was the only NOAC associated with lower rates of S/SE and MB for both doses compared to warf. Dose selection criteria cannot be ascertained from current data sources. Future studies of pts who were appropriately dosed should be warranted.

Preventable Cases of Oral Anticoagulant-Induced Bleeding: Data From the Spontaneous Reporting System
Conclusion: Our findings describe the most reported risk factors for preventability of oral anticoagulant-induced bleedings. These factors may be useful for targeting interventions to improve pharmacovigilance activities in our regional territory and to reduce the burden of medication errors and inappropriate prescription. Introduction Oral anticoagulant therapy is widely used for the prevention of stroke and systemic embolism in patients with atrial fibrillation, or for the prevention and treatment of deep vein thrombosis and pulmonary embolism (Raj et al., 1994; Monaco et al., 2017). Oral anticoagulants can be di...

Anticoagulation: Updated Guidelines for Outpatient Management.
Abstract Anticoagulation therapy is recommended for preventing, treating, and reducing the recurrence of venous thromboembolism, and preventing stroke in persons with atrial fibrillation. Direct oral anticoagulants are first-line agents for eligible patients for treating venous thromboembolism and preventing stroke in those with nonvalvular atrial fibrillation. Vitamin K antagonists are recommended for patients with mechanical valves and valvular atrial fibrillation. Vitamin K antagonists inhibit the production of vitamin K-related factors and require a minimum of five days overlap with parenteral anticoagulants, ...
