TL;DR: Effective stroke prevention (which is essentially OAC) can then be offered to AF patients with ≥1 stroke risk factor(s), with treatment decisions made in consultation with patients and incorporating their preferences.
Abstract: Atrial fibrillation (AF) confers a substantial risk of mortality and morbidity from stroke and thrombo-embolism, and this common cardiac arrhythmia represents a major healthcare burden in Europe.1 Stroke prevention is central to the management of AF patients, with the 2012 focused update of the European Society of Cardiology (ESC) guidelines2 recommending oral anticoagulation (OAC) using well-controlled adjusted dose vitamin K antagonists (VKAs, e.g. warfarin) or non-VKA oral anticoagulants (NOACs, previously referred to as new or novel OACs3) for patients with AF and ≥1 stroke risk factor(s). Also, these guidelines strongly advocate a clinical practice shift so that the initial decision step now is the identification of ‘truly low risk’ patients, essentially those aged <65 years without any stroke risk factor (both male and female), who do not need any antithrombotic therapy.2 The ESC guidelines also recommend the use of the CHA2DS2-VASc score4 for stroke risk assessment, and define ‘low-risk’ patients as those with a CHA2DS2-VASc score = 0 (males) or score = 1 (females). Subsequent to this initial step of identifying the low-risk patients, effective stroke prevention (which is essentially OAC) can then be offered to AF patients with ≥1 stroke risk factor(s), with treatment decisions made in consultation with patients and incorporating their preferences. In everyday clinical practice, over 80% of all patients with AF have an indication for OAC, and vascular disease co-exists in ∼30% of them.5–7 With an estimated prevalence of AF of 1–2% and ∼20% of these requiring percutaneous cardiovascular interventions over time,8 ∼1–2 million AF patients in Europe who are …

TL;DR: The management of AF patients in 2012 has adapted to recent evidence and guideline recommendations, and rate is often adequately controlled, and rhythm control therapy is widely used.
Abstract: Aims We sought to describe the management of patients with atrial fibrillation (AF) in Europe after the release of the 2010 AF Guidelines of the European Society of Cardiology. Methods and results The PREFER in AF registry enrolled consecutive patients with AF from January 2012 to January 2013 in 461 centres in seven European countries. Seven thousand two hundred and forty-three evaluable patients were enrolled, aged 71.5 ± 11 years, 60.1% male, CHA2DS2VASc score 3.4 ± 1.8 (mean ± standard deviation). Thirty per cent patients had paroxysmal, 24.0% had persistent, 7.2% had long-standing persistent, and 38.8% had permanent AF. Oral anticoagulation was used in the majority of patients: 4799 patients (66.3%) received a vitamin K antagonist (VKA) as mono-therapy, 720 patients a combination of VKA and antiplatelet agents (9.9%), 442 patients (6.1%) a new oral anticoagulant drugs (NOAC). Antiplatelet agents alone were given to 808 patients (11.2%), no antithrombotic therapy to 474 patients (6.5%). Of 7034 evaluable patients, 5530 (78.6%) patients were adequately rate controlled (mean heart rate 60–100 bpm). Half of the patients (50.7%) received rhythm control therapy by electrical cardioversion (18.1%), pharmacological cardioversion (19.5%), antiarrhythmic drugs (amiodarone 24.1%, flecainide or propafenone 13.5%, sotalol 5.5%, dronedarone 4.0%), and catheter ablation (5.0%). Conclusion The management of AF patients in 2012 has adapted to recent evidence and guideline recommendations. Oral anticoagulant therapy with VKA (majority) or NOACs is given to over 80% of eligible patients, including those at risk for bleeding. Rate is often adequately controlled, and rhythm control therapy is widely used.

TL;DR: This international consensus statement is intended to provide clinical guidance for the management of patients with ventricular arrhythmias and summarizes the consensus of the international writing group members and is based on a systematic review of the medical literature regarding VAs.
Abstract: This international consensus statement of the European Heart Rhythm Association (EHRA), Heart Rhythm Society (HRS), and Asia Pacific Heart Rhythm Society is intended to provide clinical guidance for the management of patients with ventricular arrhythmias (VAs). It summarizes the consensus of the international writing group members and is based on a systematic review of the medical literature regarding VAs. The spectrum of VAs ranges from those that are benign and asymptomatic to those that produce severe symptoms including sudden cardiac death (SCD). In addition, many patients exhibit multiple forms of VAs over time. Thus, clinicians who encounter patients with VAs face important questions regarding which diagnostic tests are needed and which treatments, if any, should be offered. The Writing Committee recognizes that the manner in which patients present with VAs varies greatly. The electrocardiographic recording of a VA may be the first and only manifestation of a cardiac abnormality; alternatively, patients with a prior diagnosis of cardiac disease may later develop these arrhythmias. Thus, the specific arrhythmia and the underlying structural heart disease (SHD), if any, may have important prognostic and treatment implications. This document addresses the indications for diagnostic testing, the present state of prognostic risk stratification, and the treatment strategies that have been demonstrated to improve the clinical outcome of patients with VAs. In addition, this document includes recommendations for referral of patients to centres with specialized expertise in the management of arrhythmias. Wherever appropriate, the reader is referred to other publications regarding the indications for implantable cardioverter-defibrillator (ICD) implantation,1,2 catheter ablation,3 inherited arrhythmia syndromes,4,4a,5 congenital heart disease (CHD),6 the use of amiodarone,7 and the management of patient with ICD shocks,8 syncope,9 or those nearing end of life.10 The consensus recommendations in this document …

TL;DR: The EURObservational Research Programme Atrial Fibrillation (EORP-AF) Pilot Registry has provided systematic collection of contemporary data regarding the management and treatment of AF by cardiologists in ESC member countries.
Abstract: Aims Given the advances in atrial fibrillation (AF) management and the availability of new European Society of Cardiology (ESC) guidelines, there is a need for the systematic collection of contemporary data regarding the management and treatment of AF in ESC member countries. Methods and results We conducted a registry of consecutive in- and outpatients with AF presenting to cardiologists in nine participating ESC countries. All patients with an ECG-documented diagnosis of AF confirmed in the year prior to enrolment were eligible. We enroled a total of 3119 patients from February 2012 to March 2013, with full data on clinical subtype available for 3049 patients (40.4% female; mean age 68.8 years). Common comorbidities were hypertension, coronary disease, and heart failure. Lone AF was present in only 3.9% (122 patients). Asymptomatic AF was common, particularly among those with permanent AF. Amiodarone was the most common antiarrhythmic agent used (∼20%), while beta-blockers and digoxin were the most used rate control drugs. Oral anticoagulants (OACs) were used in 80% overall, most often vitamin K antagonists (71.6%), with novel OACs being used in 8.4%. Other antithrombotics (mostly antiplatelet therapy, especially aspirin) were still used in one-third of the patients, and no antithrombotic treatment in only 4.8%. Oral anticoagulants were used in 56.4% of CHA2DS2-VASc = 0, with 26.3% having no antithrombotic therapy. A high HAS-BLED score was not used to exclude OAC use, but there was a trend towards more aspirin use in the presence of a high HAS-BLED score. Conclusion The EURObservational Research Programme Atrial Fibrillation (EORP-AF) Pilot Registry has provided systematic collection of contemporary data regarding the management and treatment of AF by cardiologists in ESC member countries. Oral anticoagulant use has increased, but novel OAC use was still low. Compliance with the treatment guidelines for patients with the lowest and higher stroke risk scores remains suboptimal.

TL;DR: Cardiovascular clinical research should shift its focus to include PROs when evaluating the efficacy of therapeutic interventions, and PRO assessments should be scientifically rigorous.
Abstract: Patient-reported outcomes (PROs), such as symptoms, health-related quality of life (HRQOL), or patient perceived health status, are reported directly by the patient and are powerful tools to inform patients, clinicians, and policy-makers about morbidity and ‘patient suffering’, especially in chronic diseases. Patient-reported outcomes provide information on the patient experience and can be the target of therapeutic intervention. Patient-reported outcomes can improve the quality of patient care by creating a holistic approach to clinical decision-making; however, PROs are not routinely used as key outcome measures in major cardiovascular clinical trials. Thus, limited information is available on the impact of cardiovascular therapeutics on PROs to guide patient-level clinical decision-making or policy-level decision-making. Cardiovascular clinical research should shift its focus to include PROs when evaluating the efficacy of therapeutic interventions, and PRO assessments should be scientifically rigorous. The European Society of Cardiology and other professional societies can take action to influence the uptake of PRO data in the research and clinical communities. This process of integrating PRO data into comprehensive efficacy evaluations will ultimately improve the quality of care for patients across the spectrum of cardiovascular disease.

TL;DR: The development of symptoms, use of antithrombotic therapy and rate vs. rhythm strategies, as well as determinants of mortality and/or stroke/transient ischaemic attack (TIA)/peripheral embolism during 1-year follow-up in this contemporary European registry of AF patients are reported.
Abstract: Background The EURObservational Research Programme-Atrial Fibrillation General Registry Pilot Phase (EORP-AF Pilot) provides systematic collection of contemporary data regarding the management and treatment of 3119 subjects with AF from 9 member European Society of Cardiology (ESC) countries. In this analysis, we report the development of symptoms, use of antithrombotic therapy and rate vs. rhythm strategies, as well as determinants of mortality and/or stroke/transient ischaemic attack (TIA)/peripheral embolism during 1-year follow-up in this contemporary European registry of AF patients. Methods The registry population comprised consecutive in- and out-patients with AF presenting to cardiologists in participating ESC countries. Consecutive patients with AF documented by ECG were enrolled. Follow-up was performed by the local investigator, initially at 1 year, as part of a long-term cohort study. Results At the follow-up, patients were frequently asymptomatic (76.8%), but symptoms are nevertheless common among paroxysmal and persistent AF patients, especially palpitations, fatigue, and shortness of breath. Oral anticoagulant (OAC) use remains high, ∼78% overall at follow-up, and of those on vitamin K antagonist (VKA), 84% remained on VKA during the follow-up, while of those on non-VKA oral anticoagulant (NOAC) at baseline, 86% remained on NOAC, and 11.8% had changed to a VKA and 1.1% to antiplatelet therapy. Digitalis was commonly used in paroxysmal AF patients. Of rhythm control interventions, electrical cardioversion was performed in 9.7%, pharmacological cardioversion in 5.1%, and catheter ablation in 4.4%. Despite good adherence to anticoagulation, 1-year mortality was high (5.7%), with most deaths were cardiovascular (70%). Hospital readmissions were common, especially for atrial tachyarrhythmias and heart failure. On multivariate analysis, independent baseline predictors for mortality and/or stroke/TIA/peripheral embolism were age, AF as primary presentation, previous TIA, chronic kidney disease, chronic heart failure, malignancy, and minor bleeding. Independent predictors of mortality were age, chronic kidney disease, AF as primary presentation, prior TIA, chronic obstructive pulmonary disease, malignancy, minor bleeding, and diuretic use. Statin use was predictive of lower mortality. Conclusion In this 1-year follow-up analysis of the EORP-AF pilot general registry, we provide data on the first contemporary registry focused on management practices among European cardiologists, conducted since the publication of the new ESC guidelines. Overall OAC use remains high, although persistence with therapy may be problematic. Nonetheless, continued OAC use was more common than in prior reports. Despite the high prescription of OAC, 1-year mortality and morbidity remain high in AF patients, particularly from heart failure and hospitalizations.

TL;DR: It is proposed that progression from paroxysmal to persistent AF can be interrupted, with potentially favourable prognostic impact, and approaches that prevent development of the AF substrate, earlier catheter ablation, and novel antiarrhythmic drugs are proposed.
Abstract: Atrial fibrillation (AF) is generally considered a progressive disease, typically evolving from paroxysmal through persistent to 'permanent' forms, a process attributed to electrical and structural remodelling related to both the underlying disease and AF itself. Medical treatment has yet to demonstrate clinical efficacy in preventing progression. Large clinical trials performed to date have failed to show benefit of rhythm control compared with rate control, but these trials primarily included patients at late stages in the disease process. One possible explanation is that intervention at only an early stage of progression may improve prognosis. Evolving observations about the progressive nature of AF, along with the occurrences of major complications such as strokes upon AF presentation, led to the notion that earlier and more active approaches to AF detection, rhythm-reversion, and maintenance of sinus rhythm may be a useful strategy in AF management. Approaches to early and sustained rhythm control include measures that prevent development of the AF substrate, earlier catheter ablation, and novel antiarrhythmic drugs. Improved classifications of AF mechanism, pathogenesis, and remodelling may be helpful to enable patient-specific pathophysiological diagnosis and therapy. Potential novel therapeutic options under development include microRNA-modulation, heatshock protein inducers, agents that influence Ca(2+) handling, vagal stimulators, and more aggressive mechanism-based ablation strategies. In this review, of research into the basis and management of AF in acute and early settings, it is proposed that progression from paroxysmal to persistent AF can be interrupted, with potentially favourable prognostic impact.

TL;DR: Based on patients' own assessment of their health status and the disease-specific AFEQT, the EHRA score can be considered a useful semi-quantitative classification.
Abstract: Aims To validate the European Heart Rhythm Association (EHRA) symptom classification in atrial fibrillation (AF) and test whether its discriminative ability could be improved by a simple modification. Methods and results We compared the EHRA classification with three quality of life (QoL) measures: the AF-specific Atrial Fibrillation Effect on QualiTy-of-life (AFEQT) questionnaire; two components of the EQ-5D instrument, a health-related utility which can be used to calculate cost-effectiveness, and the visual analogue scale (VAS) which demonstrates patients' own assessment of health status. We then proposed a simple modification [modified EHRA (mEHRA)] to improve discrimination at the point where major treatment decisions are made. quality of life data and clinician-allocated EHRA class were prospectively collected on 362 patients with AF. A step-wise, negative association was seen between the EHRA class and both the AFEQT and the VAS scores. Health-related utility was only significantly different between Classes 2 and 3 ( P < 0.001). We developed and validated the mEHRA score separating Class 2 (symptomatic AF not limiting daily activities), based on whether the patients were ‘troubled by their AF’ (Class 2b) or not (Class 2a). This produced two distinct groups with lower AFEQT and VAS scores and, importantly, both clinically and statistically significant lower health utility (Δutility 0.9, P = 0.01) in Class 2b than Class 2a. Conclusion Based on patients' own assessment of their health status and the disease-specific AFEQT, the EHRA score can be considered a useful semi-quantitative classification. The mEHRA score has a clearer separation in health utility to assess the cost efficacy of interventions such as ablation, where Class 2b symptoms appear to be the appropriate treatment threshold.

TL;DR: While the type and half-lives of VKA as well as the mode of INR surveillance differed, overall quality of anticoagulation management by TTR was relatively homogenous in AF patients across countries.
Abstract: Due to improved implementation of guidelines, new scoring approaches to improve risk categorisation, and introduction of novel oral anticoagulants, medical management of patients with atrial fibrillation (AF) is continuously improving. The PREFER in AF registry enrolled 7,243 consecutive patients with ECG-confirmed AF in seven European countries in 2012–2013 (mean age: 71.5 ± 10.7 years; 60.1% males; mean CHA2DS2-VASc score: 3.4). While patient characteristics were generally homogeneous across countries, anticoagulation management showed important differences: the proportion of patients taking vitamin K antagonists (VKAs) varied between 86.0% (in France) and 71.4% (in Italy). Warfarin was used predominantly in the UK and Italy (74.9% and 62.0%, respectively), phenprocoumon in Germany (74.1%), acenocoumarol in Spain (67.3%), and fluindione in France (61.8 %). The major sites for international normalised ratio (INR) measurements were biology laboratories in France, anticoagulation clinics in Italy, Spain, and the UK, and physicians’ offices or self-measurement in Germany. Temporary VKA discontinuation and bridging with other anticoagulants was frequent (at least once in the previous 12 months for 22.9% of the patients, on average; ranging from 29.7% in Germany to 14.9% in the UK). Time in therapeutic range (TTR), defined as at least two of the last three available INR values between 2.0–3.0 prior to enrolment, ranged from 70.3% in Spain to 81.4% in Germany. TTR was constantly overestimated by physicians. While the type and half-lives of VKA as well as the mode of INR surveillance differed, overall quality of anticoagulation management by TTR was relatively homogenous in AF patients across countries.

TL;DR: The changes in the clinical approach to arrhythmia management in ACS have been so substantial that the European Heart Rhythm Association, the Acute Cardiovascular Care Association and the European Association of Percutaneous Cardiovascular Interventions established a task force to define the current position.
Abstract: It is known that myocardial ischaemia and infarction leads to severe metabolic and electrophysiological changes that induce silent or symptomatic life-threatening arrhythmias. Sudden cardiac death is most often attributed to this pathophysiology, but many patients survive the early stage of an acute coronary syndrome (ACS) reaching a medical facility where the management of ischaemia and infarction must include continuous electrocardiographic (ECG) and hemodynamic monitoring, and a prompt therapeutic response to incident sustained arrhythmias. During the last decade, the hospital locations in which arrhythmias are most relevant have changed to include the cardiac catheterization laboratory, since the preferred management of early acute ACS is generally interventional in nature. However, a large proportion of patients are still managed medically. Both atrial and ventricular arrhythmias may occur in the setting of ACS and sustained ventricular tachyarrhythmias (VAs) may be associated with circulatory collapse and require immediate treatment. Atrial fibrillation (AF) may also warrant urgent treatment when a fast ventricular rate is associated with hemodynamic deterioration. The management of other arrhythmias is also based largely on symptoms rather than to avert progression to more serious arrhythmias. Prophylactic antiarrhythmic management strategies have largely been discouraged. Although the mainstay of antiarrhythmic therapy used to rely on antiarrhythmic drugs (AADs), particularly sodium channel blockers and amiodarone, their use has now declined, since clinical evidence to support such treatment has never been convincing. Therapy for acute coronary syndrome and arrhythmia management are now based increasingly on invasive approaches. The changes in the clinical approach to arrhythmia management in ACS have been so substantial that the European Heart Rhythm Association, the Acute Cardiovascular Care Association and the European Association of Percutaneous Cardiovascular Interventions established a task force to define the current position. Generation of the ventricular action potential by voltage and substrate dependent ion currents is the basis for …

TL;DR: The prospective, multicenter, observational Management of patients with Atrial Fibrillation undergoing Coronary Artery Stenting registry (AFCAS) registry was carried out to obtain further data on this issue.
Abstract: Background Most evidence regarding the efficacy and safety of the antithrombotic regimens for patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention with stent (PCI-S) derives from small, single-center, retrospective datasets. To obtain further data on this issue, we carried out the prospective, multicenter, observational Management of patients with Atrial Fibrillation undergoing Coronary Artery Stenting (AFCAS) registry (Clinicaltrials.gov identifier NCT00596570). Hypothesis We hypothesize that the antithrombotic treatment of AF patients undergoing PCI-S is variable and the clinical outcome may vary according to the different regimens. Methods Consecutive AF patients undergoing PCI-S at 17 European institutions were included and followed for 1 year. Outcome measures included: (1) major adverse cardiac/cerebrovascular events (MACCE), including all-cause death, myocardial infarction, repeat revascularization, stent thrombosis, or stroke/transient ischemic attack, and (2) bleeding, and were compared according to the antithrombotic regimen adopted. A propensity-score analysis was carried out to adjust for baseline and procedural differences. Results Out of the 975 patients enrolled, 914 were included in the final analysis. The mean CHADS2 score was 2.2 ± 1.2, and 71% of patients had a CHADS2 score ≥2. Triple therapy (TT) of vitamin K antagonist (VKA), aspirin, and clopidogrel was prescribed to 74% of patients, dual antiplatelet therapy to 18%, and VKA plus clopidogrel to 8%. At 1-year follow-up, no significant differences were found in the occurrence of MACCE and bleeding among the 3 antithrombotic regimens, even when adjusted for propensity score. Conclusions In this large, real-world population of AF patients undergoing PCI-S, TT was the antithrombotic regimen most frequently prescribed. Although several limitations need to be acknowledged, in our study the 1-year efficacy and safety of TT, dual antiplatelet therapy, and VKA plus clopidogrel was comparable.

TL;DR: Clinical information obtained from history and physical examination, functional and imaging studies, biochemical biomarkers, genetic/epigenetic data, and pathophysiological insights into disease-driving processes need to be integrated into a new taxonomy of CVDs to allow personalized disease management.
Abstract: There is strong need to develop the current stratified practice of CVD management into a better personalized cardiovascular medicine, within a broad framework of global patient care. Clinical information obtained from history and physical examination, functional and imaging studies, biochemical biomarkers, genetic/epigenetic data, and pathophysiological insights into disease-driving processes need to be integrated into a new taxonomy of CVDs to allow personalized disease management. This has the potential for major health benefits for the population suffering from cardiovascular diseases.

TL;DR: Generic and specialized instruments for measuring quality of life in the context of AF are reviewed, their applications and limitations to integration in clinical practice are discussed, and the potential of early therapy for improving QoL outcomes is addressed.
Abstract: Atrial fibrillation (AF) is the most frequent cardiac rhythm disorder and presents a considerable public health burden that is likely to increase in the next decades due to the ageing population. Current management strategies focus on the heart rate and rhythm control, thromboembolism prevention, and treatment of underlying diseases. The concept of quality of life (QoL) has gained significant importance in recent years as an outcome measure in AF studies evaluating therapeutic interventions and as a relevant component of a comprehensive treatment plan. Quality of life is impaired in the majority of patients with AF, and both rate and rhythm control strategies show significant improvement in QoL measures in highly symptomatic patients. This article reviews generic and specialized instruments for measuring QoL in the context of AF, discusses their applications and limitations to integration in clinical practice, and addresses the potential of early therapy for improving QoL outcomes. The development and validation of new QoL assessment tools will have a central role in the advancement of therapies and treatment guidelines for AF.

TL;DR: This task force believes that an overview on potential device options in addition to optimal medical therapy will be helpful for all physicians treating HF patients.
Abstract: Several new devices for the treatment of heart failure (HF) patients have been introduced and are increasingly used in clinical practice or are under clinical evaluation in either observational and/or randomized clinical trials. These devices include cardiac contractility modulation, spinal cord stimulation, carotid sinus nerve stimulation, cervical vagal stimulation, intracardiac atrioventricular nodal vagal stimulation, and implantable hemodynamic monitoring devices. This task force believes that an overview on these technologies is important. Special focus is given to patients with HF New York Heart Association Classes III and IV and narrow QRS complex, who represent the largest group in HF compared with patients with wide QRS complex. An overview on potential device options in addition to optimal medical therapy will be helpful for all physicians treating HF patients.

TL;DR: Persistent AF patients may suffer from more severe depressed mood than paroxysmal AF patients with similar symptom burden after controlling for relevant factors.
Abstract: Aims Despite its high clinical relevance, few studies have investigated depression in patients with atrial fibrillation (AF). We aimed to assess whether depressed mood was more common in persistent or paroxysmal AF patients in controlled models and report frequencies of major depressive disorder. Methods and results Cross-sectional data from two contemporary clinical trials were used to compare paroxysmal ( n = 310) and persistent ( n = 392) AF patients' depressed mood severity (measured by the Major Depression Inventory) with each trial including only one patient type. A four-category outcome of depressed mood severity was chosen as exposure variable. Ordinal logistic regression was applied to analyse the association of AF type with depressed mood in a crude model and a confounder control model. In the study sample, 8.4% were classified as having major depressive disorder [10.5% of persistent and 5.8% of paroxysmal patients; odds ratio (OR) = 1.89; 95% confidence interval (CI): 1.07–3.37], according to the diagnostic and statistical manual of mental disorders [(diagnostic and statistical manual of mental disorders (DSM-IV)] criteria. In both the age and sex adjusted crude model and in the confounder control model, the association of persistent AF with more severe depressed mood was significant (OR confounder controlled model = 1.44; 95% CI: 1.13–1.75, P = 0.007). Conclusion Persistent AF patients may suffer from more severe depressed mood than paroxysmal AF patients with similar symptom burden after controlling for relevant factors.

TL;DR: Patients with atrial fibrillation in Germany are often managed jointly by primary‐care physicians in cooperation with cardiologists, and the management and 1‐year outcomes of AF patients in this setting are investigated.
Abstract: Background Patients with atrial fibrillation (AF) in Germany are often managed jointly by primary-care physicians in cooperation with cardiologists. We aimed to investigate the management and 1-year outcomes of AF patients in this setting. Hypothesis We set out to describe the current management of AF patients in primary care settings in Germany. Methods Observational registry with 1-year follow-up, performed by a representative, randomly selected sample of 781 primary-care physicians in Germany. Results Of 3781 patients with electrocardiographically documented AF, 3163 patients (age 71.9 ± 9.2 years, 57.9% males) were followed for 1 year; 28.4% had paroxysmal, 27.0% persistent, and 43.3% permanent AF. Comorbid conditions were common (mean CHA2DS2-VASc score 3. 8 ± 1.7). Rhythm-control therapy was used in 16.4%. Although oral anticoagulation was often used (82.7% at baseline), stroke rate during follow-up was high (2.7% stroke, 3.0% transient ischemic attack). Despite a long duration of AF (mean duration 61 months at enrollment), 18.5% of patients were hospitalized during the 1-year follow-up. Conclusions In this unselected group of patients with long-standing AF managed in primary care, hospitalizations and cardiovascular complications including strokes are frequent, illustrating the need to improve management of AF patients.

TL;DR: XANTUS (Xarelto® for Prevention of Stroke in Patients with Atrial Fibrillation) is a prospective, international, observational, postauthorization, noninterventional study designed to collect safety and efficacy data on the use of rivaroxaban for stroke prevention in AF in routine clinical practice.
Abstract: Atrial fibrillation (AF) is associated with a fivefold increase in the risk of stroke. The Phase III 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) trial showed that rivaroxaban, an oral, direct Factor Xa inhibitor, was noninferior to warfarin for the reduction of stroke or systemic embolism in patients with AF. Compared with warfarin, rivaroxaban significantly reduced rates of intracranial and fatal hemorrhages, although not rates of bleeding overall. XANTUS (Xarelto(®) for Prevention of Stroke in Patients with Atrial Fibrillation) is a prospective, international, observational, postauthorization, noninterventional study designed to collect safety and efficacy data on the use of rivaroxaban for stroke prevention in AF in routine clinical practice. The key goal is to determine whether the safety profile of rivaroxaban established in ROCKET AF is also observed in routine clinical practice. XANTUS is designed as a single-arm cohort study to minimize selection bias, and will enroll approximately 6,000 patients (mostly from Europe) with nonvalvular AF prescribed rivaroxaban, irrespective of their level of stroke risk. Overall duration of follow-up will be 1 year; the first patient was enrolled in June 2012. Similar studies (XANTUS-EL [Xarelto(®) for Prevention of Stroke in Patients with Nonvalvular Atrial Fibrillation, Eastern Europe, Middle East, Africa and Latin America] and XANAP [Xarelto(®) for Prevention of Stroke in Patients with Atrial Fibrillation in Asia-Pacific]) are ongoing in Latin America and Asia-Pacific. Data from these studies will supplement those from ROCKET AF and provide practical information concerning the use of rivaroxaban for stroke prevention in AF.

TL;DR: Although present knowledge and MRI-associated costs do not support routine use of brain MRI in asymptomatic patients with atrial fibrillation, as more data emerge MRI may become an increasingly useful way to stratify patients with AF and individualise their treatment.
Abstract: Advances in the access to and in the performance of brain MRI have led to an increased detection of asymptomatic abnormalities in the brain of patients with cardiovascular diseases. These may have prognostic impact and could influence management in the future. In this review, we summarise the main findings of brain MRI in patients with atrial fibrillation (AF) and explore the available evidence to better quantify the risk for intracerebral haemorrhage and (recurrent) ischaemic stroke based on brain MRI findings. Treatment decisions in the majority of patients with AF should still be based on data from established validated risk scores and large randomised trials. Whether brain MRI has the potential to improve the personalised management of patients with AF by guiding the risk and benefit assessment of stroke prevention by oral anticoagulants remains to be established in large prospective studies using standardised brain MRI. However, even today, brain MRI may help to identify subsets of patients with AF at increased risk for (recurrent) intracerebral bleeding. Although present knowledge and MRI-associated costs do not support routine use of brain MRI in asymptomatic patients with AF, as more data emerge MRI may become an increasingly useful way to stratify patients with AF and individualise their treatment.

TL;DR: The combined use of OAC and AP therapy is not uncommon in AF, largely inappropriate, explained by the coexistence of coronary or peripheral arterial disease, and not influenced by considerations on the risk of bleeding.
Abstract: Purpose Combined oral anticoagulant (OAC) and antiplatelet (AP) therapy is generally discouraged in atrial fibrillation (AF) outside of acute coronary syndromes or stenting because of increased bleeding. We evaluated its frequency and possible reasons in a contemporary European AF population. Methods The PREvention oF thromboembolic events–European Registry in Atrial Fibrillation (PREFER in AF) prospectively enrolled AF patients in France, Germany, Austria, Switzerland, Italy, Spain and the UK from January 2012 to January 2013. We evaluated patterns of combined VKA-AP therapy in this population. Results Out of 7243 patients enrolled, 5170 (71.4%) were treated with OAC alone, 808 (11.2%) with AP alone and 791 (10.9%) with a combination of OAC and one (dual) or two AP (triple combination therapy). Compared with patients only prescribed OAC, patients on combination treatment had similar Body Mass Index, but more frequently diabetes (p 2 DS 2 VASc (3.7 vs 3.4), and HAS-BLED (2.7 vs 1.9) scores (for both, p Of the 660 patients on dual AP+OAC combination therapy, 629 (95.3%) did not have an accepted indication. Out of the 105 patients receiving triple combination therapy, 67 (63.8%) did not have an accepted indication. Conclusions The combined use of OAC and AP therapy is not uncommon in AF, largely inappropriate, explained by the coexistence of coronary or peripheral arterial disease, and not influenced by considerations on the risk of bleeding.

TL;DR: In this paper, the authors explored 12-month clinical outcomes of 929 patients with atrial fibrillation undergoing percutaneous coronary intervention (PCI) with bare-metal stents vs. drug-eluting stents from the prospective multicenter AFCAS registry.
Abstract: Background:We explored 12-month clinical outcomes of 929 patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) with bare-metal stents (BMS) vs. drug-eluting stents (DES) from the prospective multicenter AFCAS (Atrial Fibrillation undergoing Coronary Artery Stenting) registry.Methods and Results:Endpoints included the first occurrence of major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of all-cause death, myocardial infarction (MI), target vessel revascularization, definite/probable stent thrombosis (ST), transient ischemic attack or stroke. Bleeding events were defined according to the Bleeding Academic Research Consortium criteria. Altogether, 673 (72.4%) patients received BMS and 220 (23.7%) at least one DES. Patients treated with DES more often had diabetes and prior ischemic events, and a longer stent length (P<0.05 for all), whereas patients treated with BMS more often had heart failure and were more likely to present with acute ST-elevation MI (P<0.05 for both). At 12-month follow-up, rates and risks of MACCE and total bleeding events were comparable between the groups (22.0% with BMS vs. 19.5% with DES, P=0.51, hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.63–1.25 for DES) and (19.5% vs. 15.0%, respectively, P=0.16, HR 0.75, 95% CI 0.51–1.09 for DES). Definite/probable ST was more frequent in the BMS group (1.9% vs. 0%, respectively, P=0.046).Conclusions:In real-world patients with AF undergoing PCI, DES use was associated with outcomes comparable to those with BMS without excess bleeding complications. More ST was seen in BMS-treated patients. (Circ J 2014; 78: 2674–2681)

TL;DR: A new optical mapping system for quantification of electrical activation and repolarisation in murine atria that reliably describes activation sequences, identifies areas of functional block, and allows quantifying of conduction velocities and vectors is developed and validated.
Abstract: We developed and validated a new optical mapping system for quantification of electrical activation and repolarisation in murine atria. The system makes use of a novel 2nd generation complementary metal-oxide-semiconductor (CMOS) camera with deliberate oversampling to allow both assessment of electrical activation with high spatial and temporal resolution (128 × 2048 pixels) and reliable assessment of atrial murine repolarisation using post-processing of signals. Optical recordings were taken from isolated, superfused and electrically stimulated murine left atria. The system reliably describes activation sequences, identifies areas of functional block, and allows quantification of conduction velocities and vectors. Furthermore, the system records murine atrial action potentials with comparable duration to both monophasic and transmembrane action potentials in murine atria.

TL;DR: A systematic review and meta-analysis of tabular data addresses the benefits and risks of adding rhythm control to rate control therapy, and considers the preferential method.

TL;DR: In this paper, the impact of anaemia on the 12-month clinical outcome of patients with atrial fibrillation (AF) undergoing PCI and therefore requiring intense antithrombotic treatment was analyzed.
Abstract: Objectives Anaemia has an adverse impact on the outcome in the general patient population undergoing percutaneous coronary intervention (PCI). The aim of this study was to analyse the impact of anaemia on the 12-month clinical outcome of patients with atrial fibrillation (AF) undergoing PCI and therefore requiring intense antithrombotic treatment. We hypothesised that anaemia might be associated with a worse outcome and more bleeding in these anticoagulated patients. Setting Data were collected from 17 secondary care centres in Europe. Participants Consecutive patients with AF undergoing PCI were enrolled in the prospective, multicenter AFCAS (Atrial Fibrillation undergoing Coronary Artery Stenting) registry. Altogether, 929 patients participated in the study. Preprocedural haemoglobin concentration was available for 861 (92.7%; 30% women). The only exclusion criteria were inability or unwillingness to give informed consent. Anaemia was defined as a haemoglobin concentration of Outcome measures The primary endpoint was occurrence of major adverse cardiac and cerebrovascular events (MACCE) or bleeding events. Results 258/861 (30%) patients had anaemia. Anaemic patients were older, more often had diabetes, higher CHA 2 DS 2 -VASc scores, prior history of heart failure, chronic renal impairment and acute coronary syndrome. Anaemic patients had more MACCE than non-anaemic (29.1% vs 19.4%, respectively, p=0.002), and minor bleeding events (7.0% vs 3.3%, respectively, p=0.028), with a trend towards more total bleeding events (25.2% vs 21.7%, respectively, p=0.059). No difference was observed in antithrombotic regimens at discharge. In multivariate analysis, anaemia was an independent predictor of all-cause mortality at 12-month follow-up (hazard ratio 1.62, 95% CI 1.05 to 2.51, p=0.029). Conclusions Anaemia was a frequent finding in patients with AF referred for PCI. Anaemic patients had a higher all-cause mortality, more thrombotic events and minor bleeding events. Anaemia seems to be an identification of patients at risk for cardiovascular events and death. Trial registration ClinicalTrials.gov number NCT00596570.
