Abstract
Current optimization of atrioventricular (AV) and interventricular (VV) intervals in cardiac resynchronization therapy (CRT) is time consuming and subject to noise. We aimed to prove the principle that the best hemodynamic effect of CRT is achieved by cancelation of opposing electrical forces, detectable from the QRS morphology in the 3D vectorcardiogram (VCG). Different degrees of left (LV) and right ventricular (RV) pre-excitation were induced, using variation in AV intervals during LV pacing in 20 patients with left bundle branch block (LBBB) and variation in VV intervals during biventricular pacing in 18 patients with complete AV block or atrial fibrillation. The smallest QRS vector area identified stimulation intervals with minimal systolic stretch (median difference [IQR] 20 ms [−20, 20 ms] and maximal hemodynamic response (10 ms [−20, 40 ms]). Reliability of VCG measurements was superior to hemodynamic measurements. This study proves the principle that VCG analysis may allow easy and reliable optimization of stimulation intervals in CRT patients.

Abstract
This editorial refers to 'Gender-related differences in risk of cardiovascular morbidity and all-cause mortality in patients hospitalized with incident atrial fibrillation without concomitant diseases: a nationwide cohort study of 9519 patients' by T. Andersson et al. In order to adequately describe root causes and adverse consequences of apparently idiopathic AF, the requested study population has to be large and be followed for a very long time. Andersson et al. adequately deployed the excellent national Swedish health registries in order to cover the hiatus of aforementioned studies in the current idiopathic AF literature. Considering the notion that patients with idiopathic or lone AF have comparable prospects as AF patients overall but are only caught early in their 'arrhythmia and vascular career', the study by Andersson et al. should trigger physicians to give high priority to exposing predisposing factors or early stages of underlying cardiovascular disease in such a way that preventative measures can be accurately deployed in these patients.

Abstract
BACKGROUND Currently available antiarrhythmic drugs (AADs) for the prevention of atrial fibrillation (AF)/atrial flutter (AFL) suffer from incomplete efficacy and poor tolerability. HYPOTHESIS Dronedarone could represent an effective and safe option in patients previously treated with AADs, especially class Ic AADs and sotalol. METHODS Retrospective analysis of 2 double-blind, parallel-group trials (EURIDIS [European Trial in Atrial Fibrillation or Flutter Patients Receiving Dronedarone for the Maintenance of Sinus Rhythm] and ADONIS [American-Australian-African Trial With Dronedarone in Atrial Fibrillation or Flutter Patients for the Maintenance of Sinus Rhythm]) comparing the efficacy and safety of dronedarone with placebo over 12 months. The primary end point was AF/AFL recurrence in patients previously treated with another AAD that was discontinued for whatever reason prior to randomization. RESULTS In patients previously treated with any AADs, dronedarone decreased the risk of AF recurrence by 30.4% vs placebo (hazard ratio [HR]: 0.70; 95% confidence interval [CI]: 0.59-0.82; P < 0.001). In patients previously treated with a class Ic agent, dronedarone decreased the risk of recurrence by 31.4% (HR: 0.69; 95% CI: 0.53-0.89; P = 0.004), whereas in patients previously treated with sotalol, dronedarone showed a trend toward a decrease of risk of recurrence (HR: 0.86; 95% CI: 0.67-1.11; P = 0.244). Dronedarone was equally effective irrespective of whether class Ic or sotalol were stopped for lack of efficacy or adverse events (AEs). Discontinuation rates were similar in the 2 groups (55.9% vs 43.1%), as were incidence of AEs and serious AEs. CONCLUSIONS Dronedarone seems to be effective in preventing AF recurrences in patients without permanent AF previously treated with other AADs, even if those were discontinued for lack of efficacy. Dronedarone appears to be well tolerated even in patients who already had tolerability issues with AADs.

Abstract
BACKGROUND The choice to recommend antithrombotic therapy to patients with atrial fibrillation should rely on cardioembolic and bleeding risk stratification. Sharing some risk factors, schemes to predict thrombotic and bleeding risk are expected not to be independent, yet the degree of their association has never been clearly quantified. METHODS We described the cardioembolic (Congestive heart failure, Hypertension, Age >75, Diabetes mellitus, and prior Stroke or transient ischemic attack [CHADS2]/Congestive heart failure, Hypertension, Age >75, Diabetes mellitus, and prior Stroke or transient ischemic attack, Vascular disease, Age 65-75, Sex category i.e. females [CHA2DS2-VASc]) and bleeding risk (Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile international normalized ratio, Elderly (>65 years), Drugs/alcohol concomitantly [HAS-BLED]) co-distribution among patients of the Euro Heart Survey on atrial fibrillation. We measured the within-patient correlation (Spearman) and concordance between the 2 types of score and score-based risk categorization (low, intermediate, high). The score-based predicted risk co-classification was then related to the observed 1-year stroke and bleeding occurrence. RESULTS In 3920 patients, we found a between-scores correlation of 0.416 (P < .001) between HAS-BLED and CHADS2, and 0.512 (P < .001) between HAS-BLED and CHA2DS2-VASc. In 89% (CHADS2/HAS-BLED) and 97% (CHA2DS2-VASc/HAS-BLED) of patients, the bleeding risk category was equal to or lower than their cardioembolic risk category (P < .001 for symmetry test). A complete concordance between risk categories was found in 39.6% (CHADS2/HAS-BLED) and 21.7% (CHA2DS2-VASc/HAS-BLED) of patients; 4.4% (CHADS2/HAS-BLED) and 7.7% (CHA2DS2-VASc/HAS-BLED) of patients had high cardioembolic risk/low bleeding risk or vice versa. A tendency for an increasing frequency of stroke was observed for increasing bleeding risk within cardioembolic risk categories and vice versa. CONCLUSIONS In a real-world population with atrial fibrillation, we confirmed that the cardioembolic and bleeding risk classifications are correlated but not exchangeable. It is then worth verifying the advantages of a strategy adopting a combined risk assessment over a strategy relying only on the cardioembolic risk evaluation.

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.

Abstract
BACKGROUND The Atrial Fibrillation Follow-up Investigation of Rhythm Management trial showed that digoxin was associated with increased mortality in patients with atrial fibrillation. OBJECTIVES To assess the association of digoxin with cardiovascular (CV) morbidity and mortality in patients with permanent atrial fibrillation enrolled in the Dutch Rate Control Efficacy in Permanent AF: A Comparison Between Lenient Versus Strict Rate Control II trial as well as to assess the role of digoxin to achieve heart rate targets. METHODS The primary outcome was a composite of CV morbidity and mortality. Secondary outcomes included CV hospitalization and all-cause mortality or heart failure (HF) hospitalization. Of the 614 patients, 608 (99%) completed the dose-adjustment phase. Outcome events were analyzed from the end of the dose-adjustment phase until the end of follow-up. The median follow-up period was 2.9 years (interquartile range 2.7-3.0 years). RESULTS In total, 284 patients (46.7%) used digoxin after the dose-adjustment phase (median dosage 0.250 mg; interquartile range 0.0625-0.750 mg). These patients were more often women, previously admitted for HF, had an increased left ventricular end-systolic diameter, and more often randomized to strict rate control. By using Cox proportional hazards regression analysis, the use of digoxin was not associated with an increased risk for the primary and secondary outcomes. For the primary outcome, the 3-year estimated cumulative incidence was 12.9% vs 13.4% in the digoxin group vs the no-digoxin group (unadjusted hazard ratio [HR] 0.97; 95% confidence interval [CI] 0.62-1.52). Incidence was 19.4% vs. 19.5% for CV hospitalization (unadjusted HR 1.00; 95% CI 0.69-1.45) and 6.6% vs. 9.9% for all-cause mortality or HF hospitalization (unadjusted HR 0.62; 95% CI 0.34-1.13) in the digoxin group vs the no-digoxin group. CONCLUSION The use of digoxin was not associated with increased morbidity and mortality.

Abstract
BACKGROUND Electrophysiological studies demonstrate that a short atrial fibrillation cycle length (AFCL) is related with poor outcome of electrical cardioversion (ECV) of atrial fibrillation (AF). We found previously that the mechanical AFCL (AFCL-tvi) and atrial fibrillatory velocity (AFV-tvi) may be determined noninvasively using color tissue velocity imaging (TVI) and closely relates to the electrophysiological AFCL. OBJECTIVE To evaluate the relation between AFCL-tvi, AFV-tvi, and success of ECV in patients with AF. METHODS We prospectively studied 133 patients with persistent AF by performing echocardiography before ECV and measured the AFCL-tvi and AFV-tvi in the right atrium and left atrium. Recurrent AF was monitored. RESULTS Nineteen (14%) patients had failure of ECV, 42 (32%) remained in sinus rhythm after 1-year follow-up, and 72 (54%) had a recurrence of persistent AF. Patients with immediate ECV failure had a lower median AFV-tvi measured in the right atrium than did patients with a successful ECV: 0.7 cm/s (0.2-1.0 cm/s) vs. 1.7 cm/s (0.9-2.8 cm/s) (P = .008). Patients with maintenance of sinus rhythm after 1 year had a longer AFCL-tvi measured in the left atrium than did patients with recurrence of AF (150 ms vs 137 ms; P = .017) and had a higher AFV-tvi in both atria (1.4 vs. 0.9 cm/s in the left atrium; P = .013 and 2.2 vs 1.4 cm/s in the right atrium; P = .011). Multivariate analyses showed that all atrial TVI parameters were independently associated with the maintenance of sinus rhythm after 1 year. CONCLUSION Higher atrial fibrillatory wall velocities and longer AFCLs determined by echocardiography are associated with acute and long-term success of ECV.

Abstract
Background Coronary bronchial artery fistulas (CBFs) are rare anomalies, which may be isolated or associated with other disorders. Materials and methods Two adult patients with CBFs are described and a PubMed search was performed using the keywords “coronary bronchial artery fistulas” in the period from 2008 to 2013. Results Twenty-seven reviewed subjects resulting in a total of 31 fistulas were collected. Asymptomatic presentation was reported in 5 subjects (19 %), chest pain (n = 17) was frequently present followed by haemoptysis (n = 7) and dyspnoea (n = 5). Concomitant disorders were bronchiectasis (44 %), diabetes (33 %) and hypertension (28 %). Multimodality and single-modality diagnostic strategies were applied in 56 % and 44 %, respectively. The origin of the CBFs was the left circumflex artery in 61 %, the right coronary artery in 36 % and the left anterior descending artery in 3 %. Management was conservative (22 %), surgical ligation (11 %), percutaneous transcatheter embolisation (30 %), awaiting lung transplantation (7 %) or not reported (30 %). Conclusions CBFs may remain clinically silent, or present with chest pain or haemoptysis. CBFs are commonly associated with bronchiectasis and usually require a multimodality approach to be diagnosed. Several treatment strategies are available. This report presents two adult cases with CBFs and a review of the literature.

Abstract
BACKGROUND We evaluated the safety and effectiveness of the hybrid thoracoscopic endocardial epicardial technique for the treatment of lone atrial fibrillation. METHODS Between 2009 and 2012, a cohort of 78 consecutive patients (median age 60.5 years, 77% male) underwent ablation of atrial fibrillation (AF) as a stand-alone procedure using a thoracoscopic, hybrid epicardial-endocardial technique. All patients underwent continuous 7-day Holter monitoring at 3 months, 6 months, 1 year and yearly thereafter. All patients reached 1-year follow-up. Median follow-up was 24 months [interquartile range 12-36]. RESULTS No death or conversion to cardiopulmonary bypass occurred. No patient demonstrated paralysis of the phrenic nerve. Overall, the incidence of perioperative complications was 8% (n=6). At the end of follow-up, sixty-eight patients (87%) were in sinus rhythm (SR) with no episode of AF, atrial flutter or atrial tachycardia lasting longer than 30 seconds and off antiarrhythmic drugs (ADD). Among patients with long-standing persistent AF, 15 (100%) were in SR and off AAD. Success rates were 82% (n=28) in persistent and 76% (n=22) in paroxysmal AF (P=0.08). No patient died and no thromboembolic/bleeding events or procedure-related complications occurred during the follow-up. CONCLUSIONS Thoracoscopic hybrid epicardial endocardial technique proved to be effective and safe in the treatment of LAF and to represent an important new suitable option to treat stand-alone AF. Our findings need to be confirmed by further larger studies.

Abstract
OBJECTIVES We investigated real-life oral anticoagulation (OAC) treatment after surgical ablation and examined its adherence to current recommendations. We also explored factors related to OAC use preoperatively and at follow-up. METHODS One hundred and fifteen patients with atrial fibrillation (AF) were evaluated during 12-month follow-up after surgery. Patients were divided into two categories according to the congestive heart failure, hypertension, age ≥75 years, diabetes and prior stroke [or transient ischaemic attack or thromboembolism] (CHADS2) score: 60 patients were assigned to the high-risk group (CHADS2 score ≥2) and 55 to the low-risk group (CHADS2 score ≤1). OAC use was defined as guideline adherent, undertreatment or overtreatment. RESULTS Baseline overall guideline adherence was 62%. OAC was underprescribed in high-risk patients and overprescribed in low-risk patients (both, P < 0.001). The only factor associated with OAC use after logistic regression analysis were age >75 years (P = 0.01) and preoperative AF > paroxysmal (P = 0.013). Overall guideline adherence at 12-month follow-up showed a trend towards a better adherence in the sinus rhythm (SR) subgroup (74% vs 55%, P = 0.02). OAC was underprescribed in high-risk patients and overprescribed in low-risk patients (both P < 0.001). After logistic regression analysis, preoperative OAC use (P = 0.007) and other indications for OAC (P = 0.01) were predictors of anticoagulation treatment. CONCLUSIONS Real-life OAC prescription in AF patients showed a moderate guideline adherence, with high-risk patients being undertreated and low-risk patients being overtreated. These findings stress the importance that antithrombotic treatment in patients undergoing AF surgery needs to be critically re-evaluated.

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.

Abstract
BACKGROUND Acute atrial fibrillation (AF) is often treated with the administration of intravenous flecainide; however, this treatment may not always be successful and is potentially hazardous. Previous studies suggest that electro-echocardiographic tissue velocity imaging (TVI) of the atrial wall may reflect atrial remodeling. OBJECTIVE To study whether atrial TVI can be used to identify nonresponders of flecainide administered intravenously in patients with acute AF. METHODS We used atrial TVI to measure atrial fibrillatory cycle length determined by using tissue velocity imaging (AFCL-TVI) and atrial fibrillatory wall motion velocity determined by using tissue velocity imaging (AFV-TVI) in the left atrium in 52 (55%) patients presenting with acute AF in the emergency department. These 2 parameters reflect electrical and structural remodeling, respectively. Standard baseline characteristics were recorded. RESULTS Patients were predominantly men (76%) and 64 ± 11 years old. Thirty-six (69%) patients had successful cardioversion after flecainide infusion. There were no significant differences in baseline characteristics between responders and nonresponders. Patients with a successful cardioversion had a longer mean AFCL-TVI and higher median (interquartile range) AFV-TVI compared with patients with failed cardioversion: 172 ± 29 ms vs 137 ± 35 ms (P < .001) and 4.2 (3.3-6.2) cm/s vs 2.3 (1.9-3.5) cm/s (P = .001). CONCLUSIONS Electro-echocardiographic atrial TVI measurement is a promising noninvasive tool for predicting outcome of pharmacological cardioversion. A short AFCL-TVI and a low AFV-TVI are related to failure of cardioversion of AF using flecainide.

Abstract
AIMS This study aimed to assess safety and cardiovascular outcomes of dronedarone in patients with paroxysmal or persistent atrial fibrillation (AF) with coronary heart disease (CHD). Coronary heart disease is prevalent among AF patients and limits antiarrhythmic drug use because of their potentially life-threatening ventricular proarrhythmic effects. METHODS AND RESULTS This post hoc analysis evaluated 1405 patients with paroxysmal or persistent AF and CHD from the ATHENA trial. Follow-up lasted 2.5 years, during which patients received either dronedarone (400 mg twice daily) or a double-blind matching placebo. Primary outcome was time to first cardiovascular hospitalization or death due to any cause. Secondary end points included first hospitalization due to cardiovascular events. The primary outcome occurred in 350 of 737 (47%) placebo patients vs. 252 of 668 (38%) dronedarone patients [hazard ratio (HR) = 0.73; 95% confidence interval (CI) = 0.62-0.86; P = 0.0002] without a significant increase in number of adverse events. In addition, 42 of 668 patients receiving dronedarone suffered from a first acute coronary syndrome compared with 67 of 737 patients from the placebo group (HR = 0.67; 95% CI = 0.46-0.99; P = 0.04). CONCLUSION In this post hoc analysis, dronedarone on top of standard care in AF patients with CHD reduced cardiovascular hospitalization or death similar to that in the overall ATHENA population, and reduced a first acute coronary syndrome. Importantly, the safety profile in this subpopulation was also similar to that of the overall ATHENA population, with no excess in proarrhythmias. The mechanism of the cardiovascular protective effects is unclear and warrants further investigation.

Abstract
AIMS Quality of life (QoL) is often impaired in patients with atrial fibrillation (AF). A novel nurse-led integrated chronic care approach demonstrated superiority compared with usual care in terms of cardiovascular hospitalization and mortality. Consequently, we hypothesized that this approach may also improve QoL and AF-related knowledge, which in turn may positively correlate with QoL. METHODS AND RESULTS In this randomized controlled trial, 712 patients were randomly assigned to nurse-led care vs. usual care. Nurse-led care consisted of guidelines-based, software supported care, supervised by cardiologists. Usual care was provided by cardiologists in the regular outpatient setting. Quality of life was assessed by means of the Medical Outcomes Study 36-Item Short-Form Survey (SF-36). The Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety and depression scores. The AF knowledge scale was used to gain an insight into the patients' AF knowledge levels. Baseline QoL scores were relatively high in both groups, with median scores ranging from 55 to 100. Quality of life significantly improved over time in both groups with no significant differences between the two groups. Atrial fibrillation-related knowledge improved over time and was significantly higher at follow-up in the intervention group, compared with the usual care group (8.23 ± 2.16 vs. 7.66 ± 2.09; P < 0.05). Quality of life was correlated with gender (rs: -5.819 to -2.960), anxiety (rs: -0.746 to -0.277), depression (rs: -0.596 to -0.395), and knowledge (rs: 0.145-0.245), expressed in Spearman's rank correlation coefficient (rs). CONCLUSION Quality of life including anxiety and depression improved over time, regardless of the treatment group. The AF-related knowledge level was better in the nurse-led care group at follow-up.

Abstract
AIMS It is unknown whether lenient rate control is an acceptable strategy in patients with AF and heart failure. We evaluated differences in outcome in patients with AF and heart failure treated with lenient or strict rate control. METHODS AND RESULTS This post-hoc analysis of the RACE II trial included patients with an LVEF ≤ 40% at baseline or a previous hospitalization for heart failure or signs and symptoms of heart failure. Primary outcome was a composite of cardiovascular morbidity and mortality. Secondary endpoints were AF-related symptoms and quality of life. Two hundred and eighty-seven (46.7%) of the 614 patients had heart failure. Patients with heart failure had significantly higher NT-proBNP plasma levels, a lower LVEF, and more often used ACE inhibitors, ARBs, and diuretics. At 3 years follow-up, the primary outcome occurred more frequently in patients with heart failure (16.7% vs. 11.5%, P = 0.04). In heart failure patients, the estimated cumulative incidence of the primary outcome was 15.0% (n = 20) in the lenient and 18.2% (n = 26) in the strict group (P = 0.53). No differences were found in any of the primary outcome components, in either heart failure hospitalizations [8 (6.1%) vs. 9 (6.8%) patients in the lenient vs. strict group, respectively], symptoms, or quality of life. CONCLUSION In patients with AF and heart failure with a predominantly preserved EF, the stringency of rate control seems to have no effect on cardiovascular morbidity and mortality, symptoms, and quality of life.

Abstract
AIMS Idiopathic atrial fibrillation (AF) may be an expression of as yet undetected underlying heart disease. We found it useful for clinical practice to study the long-term development of cardiovascular disease (CVD) in patients diagnosed with idiopathic AF. METHODS AND RESULTS Forty-one consecutive idiopathic AF patients (56 ± 10 years, 66% male) were compared with 45 healthy control patients in permanent sinus rhythm. Patients were free of hypertension, antihypertensive and antiarrhythmic drugs, diabetes, congestive heart failure, coronary artery or peripheral vascular disease, previous stroke, thyroid, pulmonary and renal disease, and structural abnormalities on echocardiography. Baseline characteristics and echocardiographic parameters were equal in AF cases and controls. During a mean follow-up of 66 ± 11 months, CVD occurred significantly more often in idiopathic AF patients compared with controls (49 vs. 20%, P= 0.006). Patients with idiopathic AF were significantly younger at the time of their first CV event compared with controls (59 ± 9 vs. 64 ± 5 years, P= 0.027), and had more severe disease. Multivariable Cox regression analysis revealed that age, a history of AF, and echocardiographic left ventricular wall width were significant predictors of CVD development. CONCLUSION Patients originally diagnosed with idiopathic AF develop CVD more often, at younger age, and with a more severe disease profile compared with healthy sinus rhythm control patients. The detection and treatment of CVD in an early stage could improve the prognosis of these patients. At present it seems prudent to regularly check idiopathic AF patients for the insidious development of CVD.

Abstract
AIMS Recent increases in heart failure tend to overload the healthcare system. Consequently, there is a need for innovative strategies to reduce heart failure hospitalizations. METHODS AND RESULTS A multicentre randomized controlled trial was carried out to test the hypothesis that telemonitoring reduces heart failure hospitalizations during 1 year follow-up. The mean age of the 382 participating patients was 71.5 (32-93) years; the mean left ventricular ejection fraction was 0.38, and in 61% it was ≤0.45%. Mean time to first heart failure-related hospitalization was 161 days for the intervention group and 139 days for the usual-care group; hospitalizations occurred in 18 (9.1%) compared with 25 (13.5%) patients, with a total number of 24 and 43 hospitalizations, respectively [Kaplan-Meier P = 0.151, hazard ratio (HR) 0.65, 95% confidence interval (CI) 0.35-1.17]. Subgroup analysis of the primary endpoint showed benefits for three subgroups: duration of heart failure, having a pacemaker, and co-habiting. The combined endpoint of heart failure admission and all-cause mortality was similar for both groups (Kaplan-Meier P = 0.641, HR 0.89, 95% CI 0.69-1.83). No differences were found regarding secondary endpoints, except for the reduced number of face to face contacts with the heart failure nurse (Mann-Whitney P < 0.001). Mortality was 18 (9.1%) in the intervention group and 12 (6.5%) in the usual-care group (Mann-Whitney P = 0.34, Cox regression analysis P = 0.82). CONCLUSION No significant differences were found regarding the primary endpoint, possibly caused by a relative underpowering of the population combined with well-treated study groups. However, telemonitoring tends to reduce heart failure (re)admissions and significantly decreases contacts with specialized nurses. Further research with pre-specified groups, as found in the subgroup analysis, is needed. TRIAL REGISTRATION NCT00502255.

Abstract
BACKGROUND AND AIMS Atrial fibrillation (AF) is the most frequent sustained arrhythmia of elderly patients, in whom it determines an increase in morbidity and mortality. Aim of this study was to assess age-related differences in the characteristics, management and prognosis of patients with AF in European cardiology practices. METHODS The Euro Heart Survey on AF was an observational study sponsored by the European Society of Cardiology. Patients were enrolled between 2003 and 2004 in 182 hospitals of 35 countries. For the purposes of this study, they were categorized into three age-groups: <65 (n=2124), 65-80 (n=2534) and >80 years (n=671). Follow-up was closed in 2005. RESULTS Compared with general population estimates, patients >80 years were underrepresented in the Euro Heart Survey. The oldest patients were less likely to be enrolled by university or specialized centers, to receive extensive diagnostic testing, and to receive oral anticoagulation despite a worse stroke risk profile. Furthermore, the oldest patients less often received rhythm control therapy, even when presenting with palpitations and non-permanent AF. During 1 year follow-up, elderly patients more often suffered a myocardial infarction, new onset heart failure and major bleedings. They had higher all-cause and cardiovascular mortality. CONCLUSIONS Elderly patients with AF are less often referred to the cardiologist and, based on current guidelines, are inadequately studied and treated, compared to younger counterparts. Education on evidence- based management and the design of randomized controlled trials specifically targeting the elderly, should improve the management and prognosis of this frail segment of the AF population.

Abstract
AIMS Epicardial adipose tissue (EAT) volume has been associated with coronary artery disease (CAD). As diabetes mellitus type 2 (DM2) patients have higher EAT volumes, it has been suggested that EAT may play a role in promoting CAD in these patients. The aim of this study was to examine the association between EAT and CAD in DM2, impaired fasting glucose (IFG) and control patients presenting with stable chest pain. METHODS AND RESULTS A total of 410 stable chest pain patients underwent multidetector cardiac computed tomography angiography (CCTA) to assess the presence of CAD. The extent of CAD was expressed as the number of affected segments. The EAT volume was measured using three-dimensional volumetric quantification. The EAT was compared using ANOVA, logistic and linear regression models were used to assess its predictive value. Multivariable regression analysis corrected for traditional risk factors was performed. Eighty-three patients had DM2, 118 IFG and there were 209 controls. DM2 as well as IFG patients had higher EAT volumes compared with controls (98 ± 41, 92 ± 39, and 75 ± 34 cm(3), respectively; P < 0.001). EAT predicted the presence (OR: 1.01; P < 0.001) and the extent of CAD (B: 0.01; P < 0.001). The associations were equal in all subgroups. However, in a multivariable regression model corrected for traditional cardiovascular risk factors, EAT was not an independent predictor for the presence or extent of CAD (OR: 1.00; P = 0.88 and B: -0.11; P = 0.68, respectively). CONCLUSION The EAT volume is associated with CAD in DM2, IFG, and control patients. However, EAT is not an independent predictor for CAD in patients presenting with stable chest pain.
