What is the future of cardiovascular health? NHS Medical Director Professor Sir Stephen Powis opened the conference by outlining the growing need to provide high quality cardiovascular care. With a quarter of deaths in England attributable to cardiovascular disease and a wider cost to the economy of £15.8 billion per year,1 there is an urgent need for innovative care pathways and new technologies. He showcased virtual wards as one example of innovation, with over 100,000 patients having been managed remotely in 2022.2 In Liverpool, a Telehealth team has successfully utilised a medical monitoring app to manage patients at home, leading to a 1

Effective anticoagulation improves outcomes in patients with AF or VTE.4-7 Non-vitamin K antagonist oral anticoagulants (NOACs) have provided an alternative to warfarin for prevention of stroke or recurrent VTE in these patients in recent years. Compared with warfarin, NOACs have more predictable pharmacokinetics and pharmacodynamics, do not require monitoring of the international normalised ratio (INR), and have a wider therapeutic window that enables prescription at fixed daily doses over an extended period.8 Edoxaban, an inhibitor of Factor Xa is a member of the NOAC class. The accompanying articles summarise latest findings on the effect

Until recently, warfarin was the drug of choice for patients with atrial fibrillation. Data from the ROCKET-AF (Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation),1 ARISTOTLE (Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation),2 RE-LY (Randomized Evaluation of Long-Term Anticoagulation Therapy)3 and ENGAGE AF-TIMI 48 (Effective Anticoagulation with Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis in Myocardial Infarction 48)4 trials demonstrated non-inferior or superior reduction in str

New practical NOACs guide A new version of EHRA Practical Guide on the use of non-vitamin K antagonist oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) was launched at the congress. ESC guidelines state that NOACs should be preferred over vitamin K antagonists, such as warfarin, for stroke prevention in AF patients, except those with a mechanical heart valve or rheumatic mitral valve stenosis, and their use in clinical practice is increasing. The guide gives concrete, practical advice on how to use NOACs in specific clinical situations. The guide is published in European Heart Journal (doi: 10.1093/eurheartj/ehy136). Anti

The initiative was launched in February 2015 and in a relatively short period of time, the project achieved success in all three areas with measurable improvement in outcomes, including a reduction in hospitalisations. Over 24 months, there have been around 21,000 clinical interventions, with the emphasis being on delivering change at scale, whilst being fastidious about minimising any extra workload on primary care. In this period, 13,000 patients either started statins or had their statins changed, more than 1,000 patients with atrial fibrillation were anticoagulated, and more than 5,200 hypertensive patients reached a blood pressure targe

Approximately 20–30% of patients with AF, who are continuously taking an oral anticoagulant to reduce their risk of AF-related stroke, have coexisting coronary artery disease and may require PCI. The current practice of administering triple therapy with warfarin and two antiplatelet agents in patients with AF after a PCI is associated with high rates of major bleeding. RE-DUAL PCI tested an alternative treatment strategy: dual therapy with dabigatran and a single antiplatelet agent (P2Y12 inhibitor). Selected for one of the meeting’s hotline sessions and simultaneously published in the New England Journal of Medicine (https://doi.org/10.

Drug therapies include anticoagulants to reduce the risk of stroke and anti-arrhythmics to restore/maintain the normal heart rhythm or slow the heart rate in patients who remain in AF. Non-pharmacological management options include electrical cardioversion, which may be used to ‘shock’ the heart back to its normal rhythm. The high risk of stroke associated with electrical cardioversion can be reduced by oral anticoagulation. Although effective in reducing the risk of thromboembolism, the limitations of warfarin present considerable challenges for its use in clinical practice. The challenges of maintaining warfarin within an appropriate th

Understanding the mechanisms of AF lies at the heart of its treatment. AF occurs when structural and/or electrophysiological abnormalities alter atrial tissue to promote abnormal impulse formation and/or propagation (figure 1).3 Multiple clinical risk factors, electrocardiographic/echocardiographic features and biochemical markers are associated with an increased risk of AF (table 1), and, AF can be described in terms of the duration of episodes using a simplified scheme (table 2).3 Figure 1. Mechanisms of atrial fibrillation Table 1. Risk factors3 The aim of treatment is to prevent stroke and alleviate symptoms.4 Drug therapies include antic

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

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
