- AIMS: Atrial fibrillation (AF) is common in heart failure (HF), but few data regarding the prognostic relevance of AF are available in HF patients with preserved left ventricular ejection fraction (HF-PEF). We aimed to study the clinical impact of AF vs. sinus rhythm (SR) in stabilized HF patients with reduced left ventricular ejection fraction (HF-REF) and in those with preserved left ventricular ejection fraction (HF-PEF). METHODS AND RESULTS: We studied 927 patients with stable HF, of whom 336 (36%) had AF. N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations were measured at baseline and patients were followed for 18 months. We compared time to first HF (re-)hospitalization or death between patients with AF and SR. Atrial fibrillation was present at baseline in 215 (35%) patients with HF-REF (mean LVEF 0.25 + 0.08) and in 121 (40%) patients with HF-PEF (mean LVEF 0.50 + 0.09). Plasma NT-proBNP levels were similar in AF and SR patients (median 2398 vs. 2532 pg/mL, P = 0.74). Atrial fibrillation was independently associated with elevated NT-proBNP levels in HF-PEF, but not in HF-REF patients (multivariable B = 0.33, P= 0.047 and B = 0.03; P = 0.89, respectively). After 18 months of follow-up, the presence of AF was an independent predictor of death or HF hospitalization in HF-PEF (multivariable hazard ratio 1.49 (95% CI 1.04-2.14), P = 0.03), but not in HF-REF patients (1.05 (CI 95% 0.80-1.38), P = 0.72). CONCLUSION: Atrial fibrillation is equally common in patients with HF-PEF and HF-REF. In HF-PEF, but not in HF-REF patients, AF was associated with higher NT-proBNP levels and was independently related to death or HF hospitalization.

- The management of atrial fibrillation (AF) has seen marked changes in past years, with the introduction of new oral anticoagulants, new antiarrhythmic drugs, and the emergence of catheter ablation as a common intervention for rhythm control. Furthermore, new technologies enhance our ability to detect AF. Most clinical management decisions in AF patients can be based on validated parameters that encompass type of presentation, clinical factors, electrocardiogram analysis, and cardiac imaging. Despite these advances, patients with AF are still at increased risk for death, stroke, heart failure, and hospitalizations. During the fourth Atrial Fibrillation competence NETwork/European Heart Rhythm Association (AFNET/EHRA) consensus conference, we identified the following opportunities to personalize management of AF in a better manner with a view to improve outcomes by integrating atrial morphology and damage, brain imaging, information on genetic predisposition, systemic or local inflammation, and markers for cardiac strain. Each of these promising avenues requires validation in the context of existing risk factors in patients. More importantly, a new taxonomy of AF may be needed based on the pathophysiological type of AF to allow personalized management of AF to come to full fruition. Continued translational research efforts are needed to personalize management of this prevalent disease in a better manner. All the efforts are expected to improve the management of patients with AF based on personalized therapy.

- This survey was conducted to provide an insight into the current clinical practice regarding the use of cardioversion for atrial fibrillation (AF) in Europe. Responses were received from 57 centres across Europe, 71.9% of which were university hospitals. For electrical cardioversion, general anaesthesia was managed by an anaesthesiologist in 73.9% of centres and by a cardiologist in 37%. In the majority of centres, electrical cardioversion was performed using a biphasic defibrillator (85.1%). Antiarrhythmic drugs were routinely prescribed prior to electrical cardioversion by 54.3% of hospitals. For pharmacological cardioversion in patients with no or minimal heart disease, the majority of centres (63.1%) chose intravenous flecainide or propafenone, whereas vernakalant was used by 35% of centres in patients with no or minimal-to-moderate structural heart disease. Most centres (71.7%) used a mandatory strategy of 3 weeks of oral anticoagulation prior to elective cardioversion in patients AF > 48 h, but 28.3% performed immediate cardioversion after a transoesophageal echocardiogram. Many centres are now performing electrical cardioversion on treatment with novel oral anticoagulants (up to 23.6% of cardioversions).

Forskningsöversikt (refereegranskat)abstract
- While management of atrial fibrillation (AF) patients is improved by guideline-conform application of anticoagulant therapy, rate control, rhythm control, and therapy of accompanying heart disease, the morbidity and mortality associated with AF remain unacceptably high. This paper describes the proceedings of the 3rd Atrial Fibrillation NETwork (AFNET)/European Heart Rhythm Association (EHRA) consensus conference that convened over 60 scientists and representatives from industry to jointly discuss emerging therapeutic and diagnostic improvements to achieve better management of AF patients. The paper covers four chapters: (i) risk factors and risk markers for AF; (ii) pathophysiological classification of AF; (iii) relevance of monitored AF duration for AF-related outcomes; and (iv) perspectives and needs for implementing better antithrombotic therapy. Relevant published literature for each section is covered, and suggestions for the improvement of management in each area are put forward. Combined, the propositions formulate a perspective to implement comprehensive management in AF.

- Background Atrial fibrillation (AF) is the most common sustained arrhythmia; however, little is known about patients in a primary care setting from high-, middle-, and low-income countries. Methods and Results This prospective registry enrolled patients presenting to an emergency department with AF at 164 sites in 46 countries representing all inhabited continents. Patient characteristics were compared among 9 major geographic regions. Between September 2008 and April 2011, 15 400 patients were enrolled. The average age was 65.9, standard deviation 14.8 years, ranging from 57.2, standard deviation 18.8 years in Africa, to 70.1, standard deviation 13.4 years in North America, P<0.001. Hypertension was globally the most common risk factor for AF, ranging in prevalence from 41.6% in India to 80.7% in Eastern Europe, P<0.001. Rheumatic heart disease was present in only 2.2% of North American patients, in comparison with 21.5% in Africa and 31.5% in India, P<0.001. The use of oral anticoagulation among patients with a CHADS(2) score of 2 was greatest in North America (65.7%) but was only 11.2% in China, P<0.001. The mean time in the therapeutic range was 62.4% in Western Europe, 50.9% in North America, but only between 32% and 40% in India, China, Southeast Asia, and Africa, P<0.001. Conclusions There is a large global variation in age, risk factors, concomitant diseases, and treatment of AF among regions. Improving outcomes globally requires an understanding of this variation and the conduct of research focused on AF associated with different underlying conditions and treatment of AF and predisposing conditions in different socioeconomic settings.
