NICE NOAC guidance The National Institute for Health and Care Excellence (NICE) has recently published two recommendations on the use of novel oral anticoagulants (NOACs). NICE has recommended the NOAC dabigatran as an option for treating and preventing deep-vein thrombosis (DVT) and pulmonary embolism (PE) in adults (available in full at http://www.nice.org.uk/guidance/ta327) A final appraisal determination has also been issued for the NOAC rivaroxaban. It recommends it is an effective treatment option for preventing secondary events after acute coronary syndrome in patients with elevated cardiac biomarkers. Publication of full guidance is e

When the NOACs (novel oral anticoagulants) were introduced over three years ago, they promised to revitalise the management of conditions such as atrial fibrillation (AF), venous thromboembolism (VTE) and thromboprophylaxis after major joint replacement surgery. Rivaroxaban is currently available in multiple indications, including (but not limited to): prevention of stroke and systemic embolism in adult patients with non-valvular AF, treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE), and the prevention of recurrent DVT and PE in adults. For decades anticoagulant therapy in these conditions had relied on the vitamin K antagon

ESC guidelines and differences between NOACs Following the roll-out of the novel oral anticoagulants (NOACs), the European Society of Cardiology (ESC) published in 2012 a focused update of its guidelines for the management of atrial fibrillation (AF). Since the NOACs tested in clinical trials all showed at least non-inferiority when compared with vitamin K antagonists (VKAs), with a better safety profile, particularly with reduction in intracranial haemorrhage (ICH), the ESC 2012 guideline recommended NOACs as broadly preferable to VKAs in the vast majority of patients with non-valvular AF (NVAF).1 In 2013, the European Heart Rhythm Associati

Introduction Vitamin K antagonists (VKAs) reduce the risk of stroke in patients with atrial fibrillation (AF). For more than five decades, they were the only available treatment. Novel oral anticoagulants (NOACs) have recently been approved for the prevention of non-valvular AF-related stroke. Dose-adjusted VKA therapy and NOACs are highly effective in AF patients. However, dabigatran, rivaroxaban and apixaban are more convenient, while at least equally effective and with a comparable safety profile (regarding bleeding complications) for stroke prevention compared with VKAs.1-3 Recent guidelines prefer treatment with NOACs over VKAs for most

*citation from Havelock Ellis ‘Impressions and Comments’ Introduction Rivaroxaban is an oral direct factor Xa inhibitor belonging to the novel oral anticoagulants (NOACs) class. Concerning efficacy and tolerability, it has been reported to be more effective than enoxaparin in preventing venous thromboembolism in patients undergoing orthopaedic surgery,1,2 and was non-inferior to enoxaparin followed by warfarin in a study involving patients with established venous thrombosis.3 Its good bioavailability, rapid-action and a half-life of 5–13 h,4 associated with a highly reproducible anticoagulant activity and the same rate of bleeding compl

Summary Oral anticoagulation has been restricted to vitamin K antagonists (VKAs) for more than 50 years. Starting in the last decade of the past century, central coagulation factors such as thrombin and factor Xa were explored as potential targets for the development of novel oral anticoagulants (NOACs). This led to the successful development and approval of a novel class of direct oral anticoagulants targeting factor Xa. Rivaroxaban was the first of the novel class of agents named ‘xabans’ that are direct oral factor Xa inhibitors. Since its initial approval for thromboembolic prophylaxis after hip and knee surgery in 2008, rivaroxaban a

Background The novel oral anticoagulant (NOAC) agents (dabigatran, rivaroxaban, apixaban) have had a disproportionally poor uptake since their respective launches and National Institute for Health and Care Excellence (NICE) Technology Appraisal in the UK between 2012 and 2013 for their use in stroke prevention in patients with non-valvular atrial fibrillation (NVAF), when compared with our European counterparts; particularly Germany, Holland and France. In the original NICE economic analyses for the NOACs there was a calculated uptake of approximately 20% in the first year,1 the figure currently runs at <8% with many area’s significantly

The National Institute for Health and Care Excellence (NICE) has said that thousands of people with atrial fibrillation (AF) could be prevented from having strokes, disability or death if its new guidance is followed. It says many patients with AF are not being appropriately anticoagulated and highlights how there has not been widespread uptake of novel oral anticoagulant drugs (NOACs) which were approved by NICE in 2012. Clinical guideline 180 published in June 2014 updates and replaces the 2006 NICE clinical guideline 36.

GTN in acute stroke Dr Paul Guyler (Southend University Hospital NHS Trust) A number of major randomised controlled trials reported final results at the meeting, including the ENOS (Efficacy Of Nitric Oxide In Stroke) trial. Nitric oxide (NO) has multiple actions and is a potential candidate for the treatment of acute stroke. Among the properties which may be beneficial are lowering blood pressure, cerebral vasodilation, and improvements in central and systemic haemodynamics. NO donors are effective in experimental stroke, and pilot studies in patients suggest that one, glyceryl trinitrate (GTN), can be delivered easily as a transdermal prepa

Terry McCormack (BJC Editor, and General Practitioner) Another theme is coronary artery disease diagnosis with one article suggesting that following NICE guideline CG95 will reduce unnecessary computed tomography angiography (see page 78) whilst two other articles question whether the same guidance leads to too many invasive coronary angiograms (pages 75 and 77). We also cover exercise for heart failure (page 76), atrial fibrillation screening (pages 64−8), radiation exposure (pages 72−4) and Raza Alikhan explains how to combat haemorrhage from ODIs (pages 69−71). ODIs stands for oral direct inhibitors, which most people now know as ne
