Safety and efficacy of direct acting oral anticoagulants and vitamin K antagonists in nonvalvular atrial fibrillation - a network meta-analysis of real-world data.
CONCLUSIONS: DOACs were at least as efficacious as VKAs. In terms of safety endpoints, DOACs performed better under real-world conditions than in RCTs. The current real-world data showed that differences in efficacy and safety, despite generally low event rates, exist between DOACs. Knowledge about these differences in performance can contribute to a more personalized medicine.

Non-vitamin K oral anticoagulants (NOAC) and the risk of myocardial infarction: Differences between factor IIa and factor Xa inhibition?
Publication date: Available online 12 October 2018Source: Pharmacology & TherapeuticsAuthor(s): Amin Polzin, Lisa Dannenberg, Georg Wolff, Carolin Helten, Alina Achillles, Thomas Hohlfeld, Tobias Zeus, Malte Kelm, Steffen Massberg, Tobias PetzoldAbstractGuidelines already recommend non-vitamin K oral anticoagulants (NOAC) over vitamin-K antagonists (VKA) for stroke prevention in patients with atrial fibrillation. However, recommendations are lacking with respect to which NOAC to use. At the moment, NOACs may employ two different molecular mechanisms: Factor IIa inhibition (dabigatran) and factor Xa inhibition (apixaban, ed...

Early therapeutic persistence on dabigatran versus warfarin therapy in patients with atrial fibrillation: results from the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF) registry
We examined rates of continued use of dabigatran versus warfarin over 1 year among AF patients in the ORBIT-AF registry between June 29, 2010 and August 09, 2011. Multivariable logistic regression analysis was used to identify characteristics associated with 1-year persistent use of dabigatran therapy or warfarin. At baseline, 6.4 and 93.6% of 7150 AF patients were on dabigatran and warfarin, respectively. At 12 months, dabigatran-treated patients were less likely to have continued their therapy than warfarin-treated patients [Adjusted persistence rates: 66% (95% CI 60–72) vs. 82% (95% CI 80–84),p < .0001]. ...

Comparative risks of bleeding, ischemic stroke and mortality with direct oral anticoagulants versus phenprocoumon in patients with atrial fibrillation
ConclusionsWith rivaroxaban, no significant differences were observed compared to phenprocoumon with regard to hospitalized bleedings or ischemic strokes. Dabigatran was associated with fewer bleedings and a similar risk of ischemic strokes compared to phenprocoumon. Apixaban was also associated with fewer bleedings but was unexpectedly associated with more ischemic strokes, possibly reflecting selective prescribing. The association of rivaroxaban with higher all-cause mortality unrelated to bleedings or strokes has been described previously but remains to be explained.

Modeling the impact of real-world adherence to once-daily (QD) versus twice-daily (BID) non-vitamin K antagonist oral anticoagulants on stroke and major bleeding events among non-valvular atrial fibrillation patients.
CONCLUSION: QD NOACs prevented a significant number of strokes and caused no significant increase in MBs compared to BID NOACs which leads to significant net cost savings for NVAF patients in the US.

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.

Spontaneous choroidal hemorrhage associated with novel oral anticoagulants: A report of two cases and literature review.
We describe two clinical cases of spontaneous choroidal hemorrhage in patients treated with direct oral anticoagulants (rivaroxaban and dabigatran etexilate) for atrial fibrillation. These cases show that an ocular hemorrhagic risk exists with these drugs. Patients treated with DOAC should have the therapeutic dose adjusted based on creatinine clearance. Special monitoring should be performed in patients with age-related macular degeneration or with hypertension even though meta-analysis shows that the risk of intraocular bleeding is reduced by 22% compared with warfarin.

Real-world clinical evidence on rivaroxaban, dabigatran, and apixaban compared with vitamin K antagonists in patients with non-valvular atrial fibrillation: a systematic literature review.
Authors: Briere JB, Bowrin K, Coleman C, Fauchier L, Levy P, Folkerts K, Toumi M, Taieb V, Millier A, Wu O
Abstract
Introduction Several comparative real-world effectiveness studies on direct oral anticoagulants (DOACs) have been conducted, but an overview of the available evidence remains to be developed, which could provide a better understanding of the value of DOACs relative to vitamin K antagonists (VKAs). Areas covered A systematic literature review was conducted on the available real-world evidence (RWE) of three DOACs (rivaroxaban, dabigatran, and apixaban) compared with VKAs (e.g. warfarin), in patients wi...

Oral anticoagulant use for stroke prevention in atrial fibrillation patients with difficult scenarios
Publication date: September 2018Source: IJC Heart & Vasculature, Volume 20Author(s): Ting-Yung Chang, Jo-Nan Liao, Tze-Fan Chao, Jennifer Jeanne Vicera, Chin-Yu Lin, Ta-Chuan Tuan, Yenn-Jiang Lin, Shih-Lin Chang, Li-Wei Lo, Yu-Feng Hu, Fa-Po Chung, Shih-Ann ChenAbstractAtrial fibrillation (AF) has become the most prevalent arrhythmia and it will increase the risk of ischemic stroke, heart failure, mortality, sudden cardiac death, myocardial infarction, and dementia. Stroke prevention with oral anticoagulant is crucial for management of AF patients. Vitamin K antagonist, which inhibits the clotting factors II, VII, IX and X...

Introduction of Non-Vitamin K Antagonist Anticoagulants Strongly Increased the Rate of Anticoagulation in Hospitalized Geriatric Patients with Atrial Fibrillation
ConclusionThe introduction of non-vitamin K antagonist oral anticoagulants and an increased awareness of their benefits led to an increased use of anticoagulation from 52.8% (2011) to 87.7% (2015) in geriatric patients with atrial fibrillation and flutter at our institution.

Pharmacogenetic studies with oral anticoagulants. Genome-wide association studies in vitamin K antagonist and direct oral anticoagulants.
Authors: Cullell N, Carrera C, Muiño E, Torres N, Krupinski J, Fernandez-Cadenas I
Abstract
Oral anticoagulants (OAs) are the recommended drugs to prevent cardiovascular events and recurrence in patients with atrial fibrillation (AF) and cardioembolic stroke. We conducted a literature search to review the current state of OAs pharmacogenomics, focusing on Genome Wide Association Studies (GWAs) in patients treated with vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs). VKAs: Warfarin, acenocoumarol, fluindione and phenprocoumon have long been used, but their interindividual variability and narrow ...

Intravenous thrombolysis in stroke patients taking novel oral anticoagulants: experience with the low-dose 0.6 mg/kg of recombinant tissue-type plasminogen activator. Case reports
In the last decade, the novel oral anticoagulant (NOAC) dabigatran (a direct thrombin inhibitor), rivaroxaban, apixaban and edoxaban (direct factor Xa inhibitors) have been approved for primary and secondary prevention of stroke in patients with atrial fibrillation (AF) [1]. Compared with vitamin k antagonists such as warfarin, the NOACs offer benefits in terms of efficacy, safety and convenience [2]. The only currently approved treatment for acute stroke with a class I recommendation and level A evidence is intravenous recombinant tissue-type plasminogen activator alteplase (IV rt-PA) [4].
