Risk factors for stroke and choice of oral anticoagulant in atrial fibrillation
ConclusionsThe uptake of DOACs was rapid and spurred an increase in new users of oral anticoagulants for atrial fibrillation from 2010 to 2015 in Norway. The mean CHA2DS2-VASc score did not change substantially during this period. Vascular disease, heart failure, and diabetes were associated with initiation of warfarin, and previous stroke, age 65 –74 and female sex with initiation of DOACs.

Rivaroxaban: searching the integral vascular protection.
Authors: Barrios V, Almendro Delia M, Fácila L, García Moll X, Mazón P, Camafort M, Cepeda Rodrigo JM, Mediavilla Garcia JD, Pose Reino A, Suarez C Abstract INTRODUCTION: Residual cardiovascular risk remains high in patients with atherosclerotic cardiovascular disease despite current antithrombotic therapy. On the other hand, patients with atrial fibrillation have an increased risk of myocardial infarction and cardiovascular death. As a result, a new antithrombotic approach appears necessary to reduce this risk. Areas covered: in this article, the role of rivaroxaban on vascular protection in patients with cardi...

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.

Safety and Efficacy of Apixaban Versus Warfarin in Patients With Advanced Chronic Kidney Disease.
Conclusion and Relevance: Patients with advanced CKD taking apixaban had similar bleeding rates at 3 months compared with those taking warfarin. However, those who continued therapy had higher major bleeding rates with warfarin between 6 and 12 months. This study provides knowledge on the effects of a direct oral anticoagulant in a population that was excluded from all major trials. PMID: 29871510 [PubMed - as supplied by publisher]

Interventions and Strategies to Improve Oral Anticoagulant Use in Patients with Atrial Fibrillation: A Systematic Review of Systematic Reviews
ConclusionFindings from this overview support the superiority of NOACs and patient ’s self-management for preventing stroke in AF patients. However, uncertainties remain on the benefits of genotype-guided dosing and pharmacist-managed anticoagulation clinics due to poor quality evidence, and future research is warranted.

FDA Drug Safety Communication: FDA study of Medicare patients finds risks lower for stroke and death but higher for gastrointestinal bleeding with Pradaxa (dabigatran) compared to warfarin
[05-13-2014] In its ongoing review of the blood thinner Pradaxa (dabigatran), the U.S. Food and Drug Administration (FDA) recently completed a new study in Medicare patients comparing Pradaxa to an older blood thinner, warfarin, for risk of ischemic or clot-related stroke, bleeding in the brain, major gastrointestinal (GI) bleeding, myocardial infarction (MI), and death.

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...

New Advances In Atrial Fibrillation Management: The Role Of Apixaban.
Abstract Prevention of stroke is a pivotal intervention in the management of patients with atrial fibrillation (AF) at increased risk of systemic embolism. Because of the difficulties of safely implementing Vitamin K Antagonists in all patients, there has been a growing interest in improving the pharmacological management of AF, with newer antithrombotic agents. The new oral anticoagulants (NOACs) have been developed to overcome the limitations and improve the efficacy of the conventional oral anticoagulant drugs. Among the NOACs, apixaban - a very specific antagonist of activated factor Xa - has pharmacokinetic a...

Direct Oral Anticoagulants in Cardioversion: A Review of Current Evidence.
CONCLUSIONS: DOACs may be an attractive alternative to warfarin because of fast onset of action, potentially reducing delay to cardioversion. More robust studies are needed in patients with renal dysfunction and patients undergoing pharmacological cardioversion. PMID: 29025267 [PubMed - as supplied by publisher]

Pharmacological and Non-pharmacological Treatments for Stroke Prevention in Patients with Atrial Fibrillation
AbstractAtrial fibrillation (AF) is associated with significant risk of stroke and other thromboembolic events, which can be effectively prevented using oral anticoagulation (OAC) with either vitamin K antagonists (VKAs) or non-VKA oral anticoagulants (NOACs) dabigatran, rivaroxaban, apixaban, or edoxaban. Until recently, VKAs were the only available means for OAC treatment. NOACs had similar efficacy and were safer than or as safe as warfarin with respect to reduced rates of hemorrhagic stroke or other intracranial bleeding in the respective pivotal randomized clinical trials (RCTs) of stroke prevention in non-valvular AF...
