Atrial fibrillation (AF) is a major public health problem1 with global prevalence rates (per 1000000 population) in 2010 being 596.2 (95% uncertainty interval (UI), 558.4-636.7) in men and 373.1 (95% UI, 347.9-402.2) in women; the incidence rates increased to 77.5 (95% UI, 65.2-95.4) in men and 59.5 (95% UI, 49.9-74.9) in women.2 Worldwide, AF in association with valvular heart disease (VHD) is also common, and management strategies for this group of patients have been less addressed by randomized trials. The latter have largely focused on 'non-valvular AF' patients leading to major uncertainties over how to define (and treat) such patients. There is also an important heterogeneity in the definition of valvular and non-valvular AF.3 Some physicians assume that any valve disease should be considered as 'valvular' AF. Others consider that only mechanical valve prosthesis and rheumatic mitral stenosis should be defined as 'valvular' AF. The term valvular AF has been arbitrarily applied and the 2016 ESC guidelines have avoided the term 'valvular AF' and refer simply to 'AF related to hemodynamically significant mitral stenosis or prosthetic mechanical heart valves'.4 AF clearly leads to an incremental risk for thromboembolism in patients with mitral valve stenosis, but there are limited data for other valvular diseases. Another proposal is to use the acronym MARM-AF as a simple acronym to designate 'Mechanical and Rheumatic Mitral AF' as an alternative to term 'valvular AF' to designate the clinical scenarios for which at the non-vitamin K antagonist oral anticoagulants (NOACs) are not indicated.5 For this document we recognize the uncertainty in terminology, and our scope largely relates to AF related to 'hemodynamically significant' rheumatic VHD (ie. severe enough to impact on patient's survival or necessitates an intervention or surgery) or prosthetic mechanical heart valves. Nonetheless, thrombo-embolic (TE) risk varies according to valve lesion and may be associated with CHA2DS2VASc score risk factor components, rather than the valve disease per se being causal.6,7 TE risk may also be influenced not only by type but also the severity of the lesion. For example, the degree of mitral regurgitation may matter when it comes to risk of TE as some studies suggest that mild (Grade 1) mitral regurgitation is associated with a 2.7-fold increased risk of stroke/TE, while severe forms may possibly have a 'protective' effect (HR = 0.45 for stroke and 0.27 for LA stasis.8 An appropriate definition of 'valvular AF' would need to identify a subgroup of patients with similar pathophysiology of thrombo-embolism, TE risk, and treatment strategies6,9; however, this would be challenging given the major heterogeneity of the condition. This consensus document proposes that the term 'valvular AF' is outdated and given that any definition ultimately relates to the evaluated practical use of oral anticoagulation (OAC) type, we propose a functional EHRA (EvaluatedHeartvalves, Rheumatic orArtificial) categorization in relation to the type of OAC use in patients with AF, as follows:Evaluated Heartvalves, Rheumatic or Artificial (EHRA) Type 1,which refers to AF patients with 'VHD needing therapy with a Vitamin K antagonist (VKA)' © The Author 2016.

Stroke prevention in patients with atrial fibrillation (AF) is one pillar of the management of this common arrhythmia. Substantial advances in the epidemiology and associated pathophysiology underlying AF-related stroke and thrombo-embolism are evident. Furthermore, the introduction of the non-vitamin K antagonist oral anticoagulants (also called direct oral anticoagulants) has clearly changed our approach to stroke prevention in AF, such that the default should be to offer oral anticoagulation for stroke prevention, unless the patient is at low risk. A strategy of early rhythm control is also beneficial in reducing strokes in selected patients with recent onset AF, when compared to rate control. Cardiovascular risk factor management, with optimization of comorbidities and attention to lifestyle factors, and the patient's psychological morbidity are also essential. Finally, in selected patients with absolute contraindications to long-term oral anticoagulation, left atrial appendage occlusion or exclusion may be considered. The aim of this state-of-the-art review article is to provide an overview of the current status of AF-related stroke and prevention strategies. A holistic or integrated care approach to AF management is recommended to minimize the risk of stroke in patients with AF, based on the evidence-based Atrial fibrillation Better Care (ABC) pathway, as follows: A: Avoid stroke with Anticoagulation; B: Better patient-centred, symptom-directed decisions on rate or rhythm control; C: Cardiovascular risk factor and comorbidity optimization, including lifestyle changes. © 2023 The Author(s).

Aims: The European Society of Cardiology (ESC) EURObservational Research Programme (EORP)-Atrial Fibrillation (AF) III Registry aims to identify contemporary patterns in AF management in clinical practice, assess their compliance with the 2016 ESC AF Guidelines, identify major gaps in guideline implementation, characterize the clinical practice settings associated with good vs. poor guideline implementation and assess and compare the 1-year outcome of guideline-adherent vs. guideline non-adherent management strategies. Methods and results: Consecutive adult AF patients (n = 8306) were enrolled between 1 July 2018 and 15 July 2019, and individual patient data were prospectively collected across 192 centres and 31 participating countries during the 3-month enrolment period per centre. The Registry collected baseline and 1-year follow-up data in the eight main domains: patient demographic/enrolment setting, AF diagnosis/characterization, diagnostic assessment, stroke prevention treatments, arrhythmia-directed therapies, integrated AF management, major outcomes (death, non-fatal stroke or systemic embolic event, and non-fatal bleeding event), and the quality of life questionnaire. Conclusion: The EORP-AF III Registry is an international, prospective registry of care and outcomes of patients treated for AF, which will provide insights into the contemporary patterns in AF management, ESC AF Guidelines implementation in routine practice and barriers to optimal management of this highly prevalent arrhythmia. © 2020 Published on behalf of the European Society of Cardiology.

Aims: The risk of developing atrial fibrillation (AF) and its complications continues to increase, despite good progress in preventing AF-related strokes. Methods and results: This article summarizes the outcomes of the 7th Consensus Conference of the Atrial Fibrillation NETwork (AFNET) and the European Heart Rhythm Association (EHRA) held in Lisbon in March 2019. Sixty-five international AF specialists met to present new data and find consensus on pressing issues in AF prevention, management and future research to improve care for patients with AF and prevent AF-related complications. This article is the main outcome of an interactive, iterative discussion between breakout specialist groups and the meeting plenary. AF patients have dynamic risk profiles requiring repeated assessment and risk-based therapy stratification to optimize quality of care. Interrogation of deeply phenotyped datasets with outcomes will lead to a better understanding of the cardiac and systemic effects of AF, interacting with comorbidities and predisposing factors, enabling stratified therapy. New proposals include an algorithm for the acute management of patients with AF and heart failure, a call for a refined, data-driven assessment of stroke risk, suggestions for anticoagulation use in special populations, and a call for rhythm control therapy selection based on risk of AF recurrence. Conclusion: The remaining morbidity and mortality in patients with AF needs better characterization. Likely drivers of the remaining AF-related problems are AF burden, potentially treatable by rhythm control therapy, and concomitant conditions, potentially treatable by treating these conditions. Identifying the drivers of AF-related complications holds promise for stratified therapy. © 2020 Published on behalf of the European Society of Cardiology. All rights reserved.

There is an increasing proportion of the general population surviving to old age with significant chronic disease, multimorbidity, and disability. The prevalence of pre-frail state and frailty syndrome increases exponentially with advancing age and is associated with greater morbidity, disability, hospitalization, institutionalization, mortality, and health care resource use. Frailty represents a global problem, making early identification, evaluation, and treatment to prevent the cascade of events leading from functional decline to disability and death, one of the challenges of geriatric and general medicine. Cardiac arrhythmias are common in advancing age, chronic illness, and frailty and include a broad spectrum of rhythm and conduction abnormalities. However, no systematic studies or recommendations on the management of arrhythmias are available specifically for the elderly and frail population, and the uptake of many effective antiarrhythmic therapies in these patients remains the slowest. This European Heart Rhythm Association (EHRA) consensus document focuses on the biology of frailty, common comorbidities, and methods of assessing frailty, in respect to a specific issue of arrhythmias and conduction disease, provide evidence base advice on the management of arrhythmias in patients with frailty syndrome, and identifies knowledge gaps and directions for future research. © The Author(s) 2023.

Hypertension is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease, stroke, peripheral artery disease and chronic renal insufficiency. Hypertensive heart disease can manifest as many cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in hypertensive patients, especially in those with left ventricular hypertrophy (LVH) or HF. Also, some of the antihypertensive drugs commonly used to reduce blood pressure, such as thiazide diuretics, may result in electrolyte abnormalities (e.g. hypokalaemia, hypomagnesemia), further contributing to arrhythmias, whereas effective control of blood pressure may prevent the development of the arrhythmias such as AF. In recognizing this close relationship between hypertension and arrhythmias, the European Heart Rhythm Association (EHRA) and the European Society of Cardiology (ESC) Council on Hypertension convened a Task Force, with representation from the Heart Rhythm Society (HRS), Asia-Pacific Heart Rhythm Society (APHRS), and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE), with the remit to comprehensively review the available evidence to publish a joint consensus document on hypertension and cardiac arrhythmias, and to provide up-to-date consensus recommendations for use in clinical practice. The ultimate judgment regarding care of a particular patient must be made by the healthcare provider and the patient in light of all of the circumstances presented by that patient. © The Author 2017.

There are major challenges ahead for clinicians treating patients with atrial fibrillation (AF). The population with AF is expected to expand considerably and yet, apart from anticoagulation, therapies used in AF have not been shown to consistently impact on mortality or reduce adverse cardiovascular events. New approaches to AF management, including the use of novel technologies and structured, integrated care, have the potential to enhance clinical phenotyping or result in better treatment selection and stratified therapy. Here, we report the outcomes of the 6th Consensus Conference of the Atrial Fibrillation Network (AFNET) and the European Heart Rhythm Association (EHRA), held at the European Society of Cardiology Heart House in Sophia Antipolis, France, 17-19 January 2017. Sixty-two global specialists in AF and 13 industry partners met to develop innovative solutions based on new approaches to screening and diagnosis, enhancing integration of AF care, developing clinical pathways for treating complex patients, improving stroke prevention strategies, and better patient selection for heart rate and rhythm control. Ultimately, these approaches can lead to better outcomes for patients with AF. © The Author 2018.
