Time in therapeutic range (TTR) of international normalized ratio is crucial for the safety and efficacy of anticoagulation with warfarin and it is influenced by many factors. There are limited data about the quality of warfarin therapy and its effects on clinical outcomes in Turkey. The aim of this study is to demonstrate the quality of anticoagulant therapy with warfarin and evaluate the parameters that affect the quality of warfarin therapy. A total of 170 patients with atrial fibrillation (AF; mean age: 62...

BACKGROUND: The nonvitamin K antagonist oral anticoagulants have recently become available as an alternative to warfarin as stroke prophylaxis in atrial fibrillation, but data on real-life patient experience, including bleeding risk, are lacking. Our objective was to compare major bleeding events and nonpersistence between the nonvitamin K antagonist oral anticoagulant apixaban and other nonvitamin K antagonist oral anticoagulants (dabigatran and rivaroxaban) and warfarin in a contemporary, nation-wide cohort of patients with nonvalvular atrial fibrillation...

BACKGROUND: The optimal management of stroke prophylaxis in hemodialysis patients with atrial fibrillation is controversial. OBJECTIVE: The purpose of this study was to determine the risk of mortality, stroke, and bleeding associated with the use of warfarin in hemodialysis patients with atrial fibrillation.

AIM: The aim of this study is to examine temporal trends in the use oral anticoagulants (OAC) as stroke prophylaxis in patients with atrial fibrillation (AF) and to examine factors associated with OAC initiation. METHODS AND RESULTS: From Danish nationwide registries, we identified patients diagnosed with AF at Danish hospitals and outpatient clinics between January 2005 and June 2015. OAC initiation was assessed from prescription fills ±180 days from date of AF diagnosis...

Background Updated evidence-based guidelines for the management of atrial fibrillation (AF) necessitate patient review, particularly with respect to oral anticoagulants, to ensure maximum health gain around stroke prophylaxis. Objective To quantify the level of anticoagulation utilisation in patients with a CHA2DS2-VASc ≥1/≥2 (male/female) according to evidence-based guidelines and to assess the impact of a pharmacist-led intervention to optimise therapy. Setting Fifteen general medical practices in Liverpool, North-West England with a practice population of 99,129...

The utility of anticoagulants for ischemic stroke prophylaxis in elderly patients with chronic kidney disease (CKD) and atrial fibrillation remains uncertain. In this population-based retrospective cohort study, we determined the association of anticoagulant use with ischemic stroke or hemorrhage in elderly patients (66 years and older) with advanced chronic kidney disease (eGFR under 45 ml/min/1.73m(2)) and atrial fibrillation. We followed 6,544 patients with CKD and new onset atrial fibrillation, of whom 1,475 filled a prescription for an anticoagulant...

OBJECTIVE: Warfarin is widely used for stroke prevention in patients with nonvalvular atrial fibrillation (NVAF). We compared the rates of stroke and major bleeding in NVAF patients with a high stroke risk and low bleeding risk profile during warfarin treated (W+) and warfarin untreated (W-) periods. METHOD: Insurance claims from six commercial, Medicaid or Medicare databases were analyzed from 2000 to 2014. NVAF patients treated with warfarin, with a CHADS2/CHA2DS2-VASc score ≥2, and an ATRIA score ≤3 at baseline were identified...

OBJECTIVES: Postoperative atrial fibrillation (POAF) remains a major risk after cardiac surgery. Twelve percent patients admitted to this unit postcardiac surgery experienced POAF, which led to hemodynamic instability, increased risk of stroke, and increased length of postoperative intensive care unit stay. Our aim was to decrease the incidence of POAF in the cardiothoracic intensive care unit by the end of April 2014. METHODS: Design-Retrospective data analysis...

BACKGROUND: Non-vitamin K antagonist oral anticoagulants (NOACs, dabigatran, rivaroxaban, apixaban, and edoxaban) have been increasingly used as alternatives to warfarin for stroke prophylaxis in patients with atrial fibrillation. Yet there is substantial lack of information on how patients on NOACs are currently treated when they have an acute ischemic stroke and the best strategies for treating intracerebral hemorrhage for those on chronic anticoagulation with warfarin or a NOAC. These are critical unmet needs for real world clinical decision making in these emergent patients...

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, and is associated with a fivefold increase in the risk of ischemic stroke and systemic embolism. Left atrial appendage (LAA) is the source of thrombi in up to 90% of patients with nonvalvular atrial fibrillation (AF). Although thromboembolic prophylaxis by means of oral anticoagulants (OAC) has been shown to be very effective (OAC), they also confer an inevitably risk of serious bleeding. Catheter ablation (CA) is an effective treatment for symptomatic AF but its role in stroke prevention remains unproved...

In the latest American Heart Association/American College of Cardiology/Heart Rhythm Society atrial fibrillation (AF) guidelines, CHA2DS2-VASc replaced the CHADS2 stroke risk assessment to determine prophylactic anticoagulation, reflecting female gender's association with stroke incidence in AF. However, little investigation has been pursued of potential risk factors associated with worsened stroke severity. In this study, we examined patients with AF with ischemic stroke patient characteristics associated with increased stroke severity...

BACKGROUND: Venous thromboembolism (VTE) is a common complication that manifests during and/or after hospitalization, as well as postsurgeries including orthopedic surgeries. Edoxaban is a new oral direct factor Xa inhibitor that has been recently approved for treating VTE in patients who have already been treated with a parenteral anticoagulant and for the prevention of stroke and non-central nervous system systemic embolism in patients with nonvalvular atrial fibrillation. OBJECTIVES: The purpose of this systematic review was to evaluate the safety and efficacy of edoxaban for VTE prophylaxis after lower limb orthopedic surgery...

Among patients with atrial fibrillation, prophylaxis for stroke prevention with the use of anticoagulation is well established in the general population. A number of randomized controlled trials and evidence-based risk prediction tools clearly delineate the benefit and risks of therapy. Despite the high incidence of atrial fibrillation in the late stage CKD and ESRD populations, little high quality evidence exists in these populations. Is it appropriate then to extrapolate findings from the general population to those with CKD/ESRD? In our view, too much uncertainty exists regarding proof of efficacy with clear signals of harm...

BACKGROUND: Non-vitamin K antagonist (VKA) oral anticoagulants (NOACs) are widely used as stroke prophylaxis in non-valvular atrial fibrillation (AF), but comparative data are sparse. PURPOSE: To compare dabigatran, rivaroxaban, and apixaban vs. VKA and the risk of stroke/thromboembolism (TE) and intracranial bleeding in AF. METHODS: Using Danish nationwide registries (2011-15), anticoagulant-naïve AF patients were identified when initiating VKA or an NOAC...

Oral vitamin K antagonists (VKA) such as warfarin have been the mainstay of therapy for stroke prevention in patients with non valvular atrial fibrillation (NVAF) while low-molecular-weight heparin, fondaparinux and adjusted-dose warfarin or aspirin have been routinely used for thromboembolism (VTE) prophylaxis in patients undergoing total hip or knee replacement. However, VKAs are associated with considerable limitations, including increased risk of bleeding and narrow therapeutic window. Novel oral anticoagulants (NOACs, now referred as Non Vit K dependent oral anticoagulants), including the direct thrombin inhibitor dabigatran and direct Factor Xa inhibitors such as rivaroxaban and apixaban are now approved alternatives to warfarin for prophylaxis of stroke and systemic embolic events (SEE) in patients with NVAF and treatment and prophylaxis of VTE...

No direct comparisons of these strategies are available from randomized controlled trials.
