Atrial 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 patients...

Benjamin A Steinberg, Jeffrey B Washam
The development of nonvitamin K antagonist oral anticoagulants (NOACs) has been a major advance in therapy for patients requiring oral anticoagulation, particularly for long-term indications such as stroke prevention in atrial fibrillation (AF). The NOACs are generally easier to dose and manage due to less heterogeneity of effect across individuals and fewer drug and food interactions, compared with warfarin. However, the treatment effect of NOACs may vary based on important patient characteristics, particularly renal function...

In the Edoxaban Versus Enoxaparin-Warfarin in Patients Undergoing Cardioversion of Atrial Fibrillation (ENSURE-AF) study (NCT 02072434), edoxaban was compared with enoxaparin-warfarin in 2,199 patients undergoing electrical cardioversion of nonvalvular atrial fibrillation (AF). In this multicenter prospective randomized open blinded end-point trial, we analyzed patients randomized to enoxaparin-warfarin. We determined time to achieve therapeutic range (TtTR); time in therapeutic range (TiTR); their clinical determinants; relation to sex, age, medical history, treatment, tobacco use, race risk (SAMe-TT2R2) score; and impact on primary end points (composite of stroke, systemic embolic event[SEE], myocardial infarction [MI], and cardiovascular death [CVD] and composite of major + clinically relevant nonmajor bleeding)...

Direct oral anticoagulants (DOACs) are novel direct-acting medications that are selective for either thrombin or activated factor X. Due to their obvious benefits for patients (fewer interactions, broader therapeutic window, etc.), they are increasingly used as an alternative to warfarin, phenprocoumon, or acenocoumarol. One of the major indications for use of DOACs is stroke prevention in patients with atrial fibrillation (AF). However, interactions still exist, especially in combination with antiarrhythmic drugs (AADs), which are frequently given to AF patients for rhythm or rate control...

Atrial fibrillation (AF) represents the most common arrhythmia in patients with chronic kidney disease (CKD). As in the general population, AF is associated with an increased risk of thromboembolism and stroke, according to progressive decline of glomerular filtration rate (GFR). However, CKD patients, especially those on renal replacement therapy (RRT), also exhibit an increased risk of bleeding, especially from the gastrointestinal tract. Oral anticoagulation is the most effective form of thromboprophylaxis in patients with AF presenting increased risk of stroke...

Aim To examine the choices Canadian family medicine residents make for oral anticoagulation (OAC) for patients with nonvalvular atrial fibrillation (AF). BACKGROUND: AF increases the risk of strokes. An important consideration in AF management is risk stratification for stroke and prescription of appropriate OAC. Family physicians provide the vast majority of OAC prescriptions. METHODS: We administered a survey to residents in multiple Canadian family medicine training programmes...

Dabigatran etexilate (DE) is a direct thrombin inhibitor, which has been approved for the treatment of non-valvular atrial fibrillation (AF), and for the prevention and treatment of venous thromboembolism (VTE). Despite large randomized clinical trials and independent observational studies providing robust data concerning DE safety and efficacy, some physicians still perceive mild-to-moderate renal impairment and old age as a relative contraindication to its use. In this article, we review the available scientific evidence supporting the use of DE in these clinical situations...

Vitamin K antagonist warfarin is widely used in clinical practice and excessive anticoagulation is a well-known complication of this therapy. Little is known about permanent and temporary predictors for severe overanticoagulation. The aim of this study was to investigate the occurrence and predicting factors for episodes with very high (≥9) international normalized ratio (INR) values in warfarin treated patients with atrial fibrillation (AF). Excessive Warfarin Anticoagulation (EWA) study screened all patients (n = 13618) in the Turku University Hospital region with an INR ≥2 between years 2003-2015...

The review shows the prevalence of atrial fibrillation (AF) in patients with chronic kidney disease (CKD), depending on the severity of the disease. Patients with non-valvular AF and CKD have a significantly increased risk of both bleeding and thromboembolic complications, and death from all causes. Evaluation of the results of randomized clinical trials (RCTs), meta-analyzes of RCTs demonstrated the advantages of the new oral anticoagulants (NOAC), such as dabigatran, rivaroxaban, apixaban, compared with warfarin in reducing the risk of bleeding in patients with AF and CKD in predialysis stage...

BACKGROUND: There is increasing evidence questioning the use of warfarin for atrial fibrillation (AF) among older adults with end stage renal disease (ESRD). We assessed the patterns and determinants of warfarin utilization among these patients in the US. METHODS: We assembled a cohort of older adults (age ≥65) undergoing dialysis with incident AF from July 2007 to November 2011 from the US Renal Data System (USRDS). We used descriptive statistics to characterize warfarin utilization within 30 days of AF discharge, and logistic regression to quantify patient characteristics associated with warfarin initiation...

INTRODUCTION: Few data are available about safety of vitamin K antagonists (VKAs) in patients with clinical/demographic characteristics predisposing to an increased risk of bleeding. We performed a meta-analysis to evaluate the safety of VKAs in patients with atrial fibrillation (AF) or venous thromboembolism (VTE) in the following subgroups of "high-risk" patients: elderly patients, patients with low body weight and patients with impaired renal function. MATERIALS AND METHODS: Major electronic databases were systematically searched to identify randomized controlled trials (RCTs) addressing this issue...

Atrial fibrillation (AF) is an independent risk factor for stroke. It is most prevalent in the elderly and frequently coexists with heart failure (HF). The joint occurrence of AF and HF further worsens prognosis. The prevention of thromboembolism is crucial in the management of AF. In recent years, new oral anticoagulants (NOACs) have been licensed for the prevention of stroke and systemic embolism in patients with AF. Areas covered: This article reviews the key published studies on the pharmacology, clinical efficacy and safety of edoxaban, the latest NOAC to receive approval for the AF indication...

The high risk of both stroke and major bleeding in atrial fibrillation (AF) patients with chronic kidney disease (CKD) defines an important population for whom the assessment of the balance between the risk of ischemic stroke and of bleeding is essential. The use of novel oral anticoagulants (NOACs) may be a viable option in this population due to their greater net clinical benefit than warfarin, as demonstrated by the results of the clinical phase III trials. NOACs have been found to have a greater net clinical benefit than warfarin in patients at high risk of either stroke (CHADS2≥1 or CHA2DS2-VASc score≥2) or bleeding (HAS-BLED≥3)...

Atrial fibrillation (AF) is a major risk factor for stroke in the elderly population. The use of anticoagulation in patients with AF greatly reduces the risk for stroke, but results in an increased risk of bleeding. Over the past several years, direct oral anticoagulants (DOACs, dabigatran, rivaroxaban, and apixaban) have been used in place of warfarin for stroke prevention in AF. We conducted a retrospective cohort study to assess the safety of DOACs in very elderly patients (75+) managed in a health care system encompassing both community and academic settings...
