For patients with cancer who experience venous thromboembolism (VTE), low-molecular-weight heparin (LMWH) remains the standard of care in the NCCN Guidelines for VTE, but under certain conditions direct oral anticoagulants (DOACs) are acceptable alternatives. A growing body of literature suggests that DOACs may more effective than LMWHs in preventing recurrences, but they do carry some increased risk of bleeding. Most of this risk is seen in patients with gastrointestinal or urinary pathology or implanted devices...

In the clinical practice a physician quite often is at a loss due to "freedom of choice" granted by availability of direct oral anticoagulants (DOAC). If a patient with nonvalvular atrial fibrillation (AF) has indications for therapy with anticoagulants which DOAC should be preferred? What are benefits for a patient with ischemic heart disease and AF when definite NOAC is chosen and what are risks inherent of this choice? Answers to such questions are given in this paper.

BACKGROUND: Extended duration anticoagulation is beneficial for preventing recurrent venous thromboembolism (VTE). Reduced dose direct oral anticoagulants (DOACs) may be preferable if they preserve efficacy and cause less bleeding. We conducted a systematic review and meta-analysis of trials comparing reduced dose DOACs with full dose DOACs and aspirin or placebo in the extended phase of VTE treatment. METHODS: A literature search was conducted using the MEDLINE, EMBASE and CINAHL databases supplemented by hand-searching...

BACKGROUND: Current consensus guidelines suggest DOACs are interrupted peri-procedurally for catheter ablation (CA) of AF. However, this may predispose patients to thromboembolic complications. This study investigates the safety of CA for AF on uninterrupted DOACs compared to uninterrupted warfarin. METHODS: Single centre, retrospective study of consecutive patients undergoing CA for AF. All patients were heparinised prior to trans-septal puncture with a target activated clotting time (ACT) of 300-350 seconds...

BACKGROUND: Oral anticoagulation (OAC) is prescribed for left atrial thrombi (LAT) in non-rheumatic atrial fibrillation (AF) and/or atrial flutter (AFL). The study objective was to review the existing evidence regarding LAT resolution in non-rheumatic AF and/or AFL with OAC agents. METHODS: Data sources included PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) between January 1, 1991 and February 1, 2017. English-language studies that assessed LAT resolution with OAC agents in subjects with non-rheumatic AF and/or AFL, by serial transesophageal echocardiography (TEE), and with follow-up times ≥3 weeks and < 1 year were selected...

BACKGROUND: Apixaban is a direct oral anticoagulant (DOAC) with a specific inhibition of activated factor X (FXa). In case of bleeding or need of urgent surgery a direct antidote is not yet available. Off-label application of non-specific haemostatic agents, such as prothrombin complex concentrate (PCC) and recombinant FVIIa (rFVIIa), has been reported to reverse the effects of apixaban in in vitro and animal studies. The aim of this study is to measure the reversal potential of PCC and rFVIIa in patients with prophylactic apixaban concentrations...

In 2008, we decided to enter the era of direct oral anticoagulants (DOACS). Was that the right decision to make? The answer will depend on how well we meet the conditions of proper use. This means avoiding underdosing and overdosing as well as understanding how DOACS were validated so that our prescriptions fulfill their role in the management of thrombotic disease.

INTRODUCTION: Despite the increasing utilization of direct oral anticoagulant (DOAC) prescriptions, vitamin K antagonists (VKAs) remain the treatment of choice for treating and preventing thromboembolic events. The morbidity and mortality of VKAs are partly due to the difficulty of keeping the patient within the therapeutic range. For patients treated by VKA, time in therapeutic range (TTR) is a quality parameter of treatment, widely used in clinical trials but rarely by prescribers. It is well established that its use correlates with the risk of hemorrhage, thrombosis or mortality...

Vitamin K antagonists (VKAs), such as warfarin, have been used for thromboprophylaxis and for the treatment of thromboembolic events in patients with nonvalvular atrial fibrillation for over 60 years. The increasing use of direct oral anticoagulants (DOACs) in recent years has shown greater advantages and safer use over VKA, including reduced bleeding, fewer drug interactions, no food interactions, a quick onset and offset of activity, and predictable dose-response properties. Despite their advantages, there are a couple of major limitations that raise concerns among clinicians, including the need for more coagulation assays to monitor their effects and more specific reversal antidotes in life-threatening circumstances of bleeding...

Atrial fibrillation (AF) is associated with high risk of systemic thromboembolism leading to significant morbidity and mortality. Warfarin, previously the mainstay for stroke prevention in AF, requires close monitoring because of multiple food and drug interactions. In recent years, food and drug administration has approved several direct oral anticoagulants (DOACs) for use in patients with nonvalvular AF. These agents have not been studied in patients with valvular AF who are at an even higher risk of systemic thromboembolism...

Purpose: To analyze and compare the signals of bleeding from the use of direct-acting oral anticoagulants (DOACs) in the US Food and Drug Administration Adverse Event Reporting System (FAERS) database over 5 years. Methods: Reports of bleeding and of events with related terms submitted to the FAERS between October 2010 and September 2015 were retrieved and then analyzed using the reporting odds ratio (ROR). The signals of bleeding associated with DOAC use were compared with the signals of bleeding associated with warfarin use utilizing the FAERS databases...

INTRODUCTION: Direct oral anticoagulants (DOACs) are increasingly prescribed for prevention of thromboembolic stroke, as well as for prevention and treatment of venous thromboembolism. Dose adjustment based on laboratory testing is not required; however, there are several potential situations that deserve insight into a DOAC plasma activity level. METHODS: Based on a series of real-life case descriptions, we discuss indications for dedicated DOAC testing, as well as the interpretation and consequences...

PURPOSE: The potential link between serious or life-threatening bleeding and the use of direct oral anticoagulants (DOACs) was evaluated. METHODS: Qualitative and quantitative reviews of case reports of bleeding events involving dabigatran, rivaroxaban, apixaban, edoxaban, and warfarin through March 31, 2017, were performed. A disproportionality analysis was conducted for each DOAC using an empirical Bayesian approach based on the relative reporting rate. Subanalyses were performed to assess (1) bleeding events (including mortality and life-threatening events) associated with DOACs among all adverse-event reports and (2) warfarin-related bleeding events...
