RESUMO
BACKGROUND: Screening of high-risk patients is advocated to achieve early detection and treatment of clinical atrial fibrillation (AF). The Dutch-GERAF study will address two major issues. Firstly, the effectiveness and feasibility of an opportunistic screening strategy for clinical AF will be assessed in frail older patients and, secondly, observational data will be gathered regarding the efficacy and safety of oral anticoagulation (OAC). METHODS: This is a multicentre study on opportunistic screening of geriatric patients for clinical AF using a smartphone photoplethysmography (PPG) application. Inclusion criteria are age ≥â¯65 years and the ability to perform at least three PPG recordings within 6 months. Exclusion criteria are the presence of a cardiac implantable device, advanced dementia or a severe tremor. The PPG application records patients' pulse at their fingertip and determines the likelihood of clinical AF. If clinical AF is suspected after a positive PPG recording, a confirmatory electrocardiogram is performed. Patients undergo a comprehensive geriatric assessment and a frailty index is calculated. Risk scores for major bleeding (MB) are applied. Standard laboratory testing and additional laboratory analyses are performed to determine the ABC-bleeding risk score. Follow-up data will be collected at 6 months, 12 months and 3 years on the incidence of AF, MB, hospitalisation, stroke, progression of cognitive disorders and mortality. DISCUSSION: The Dutch-GERAF study will focus on frail older patients, who are underrepresented in randomised clinical trials. It will provide insight into the effectiveness of screening for clinical AF and the efficacy and safety of OAC in this high-risk population. TRIAL REGISTRATION: NCT05337202.
RESUMO
BACKGROUND: Early aspirin withdrawal, also known as P2Y12-inhibitor monotherapy, following percutaneous coronary intervention (PCI) for non-ST-segment elevation acute coronary syndrome (NSTE-ACS) can reduce bleeding without a trade-off in efficacy. Still the average daily bleeding risk is highest during the first months and it remains unclear if aspirin can be omitted immediately following PCI. METHODS: The LEGACY study is an open-label, multicenter randomized controlled trial evaluating the safety and efficacy of immediate P2Y12-inhibitor monotherapy versus dual antiplatelet therapy (DAPT) for 12 months in 3,090 patients. Patients are randomized immediately following successful PCI for NSTE-ACS to 75-100 mg aspirin once daily versus no aspirin. The primary hypothesis is that immediately omitting aspirin is superior to DAPT with respect to major or minor bleeding defined as Bleeding Academic Research Consortium type 2, 3, or 5 bleeding, while maintaining noninferiority for the composite of all-cause mortality, myocardial infarction and stroke compared to DAPT. CONCLUSIONS: The LEGACY study is the first randomized study that is specifically designed to evaluate the impact of immediately omitting aspirin, and thus treating patients with P2Y12-inhibitor monotherapy, as compared to DAPT for 12 months on bleeding and ischemic events within 12 months following PCI for NSTE-ACS.

AIMS: It is common practice for clinicians to advise fluid restriction in patients with heart failure (HF), but data from clinical trials are lacking. Moreover, fluid restriction is associated with thirst distress and may adversely impact quality of life (QoL). To address this gap in evidence, the Fluid REStriction in Heart failure vs liberal fluid UPtake (FRESH-UP) study was initiated. METHODS: The FRESH-UP study is a randomized, controlled, open-label, multicenter trial to investigate the effects of a 3-month period of liberal fluid intake vs fluid restriction (1500 mL/day) on QoL in outpatients with chronic HF (New York Heart Association Classes II--III). The primary aim is to assess the effect on QoL after 3 months using the Overall Summary Score of the Kansas City Cardiomyopathy Questionnaire (KCCQ). Thirst distress, as assessed by the Thirst Distress Scale for patients with HF, KCCQ Clinical Summary Score, each of the KCCQ domains and clinically meaningful changes in these scores, the EQ-5D-5L, patient-reported fluid intake and safety (ie, death, HF hospitalizations) are secondary outcomes. The FRESH-UP study is registered at ClinicalTrials.gov (NCT04551729). CONCLUSION: The results of the FRESH-UP study will add substantially to the level of evidence concerning fluid management in chronic HF and may impact the QoL of these patients.

OBJECTIVE: There is a significant cardiac morbidity and mortality after endovascular aneurysm repair (EVAR). However, information about long-term risk of cardiac events after EVAR and potential predictors is lacking. Therefore, the aim of this study was to determine incidence and predictors of major adverse cardiac events (MACE) at 1 and 5 years after elective EVAR for infrarenal abdominal aortic aneurysms. METHODS: Baseline, perioperative, and postoperative information of 320 patients was evaluated. The primary outcome was the incidence of MACE after EVAR, which was defined as acute coronary syndrome, unstable angina pectoris, de novo atrial fibrillation, hospitalization for heart failure, mitral valve insufficiency, revascularization (including percutaneous coronary intervention and coronary artery bypass grafting), as well as cardiovascular and noncardiovascular death. Kaplan-Meier analyses were performed to determine incidences of MACE, MACE excluding noncardiovascular death and cardiac events by excluding noncardiovascular and vascular death from MACE. Predictors of MACE were identified using univariate and multivariate binary regression analysis. RESULTS: Through 1 and 5 years of follow-up after EVAR, freedom from MACE was 89.4% (standard error [SE], 0.018) and 59.8% (SE, 0.033), freedom from MACE excluding noncardiovascular death was 94.7% (SE, 0.013) and 77.5% (SE, 0.030) and freedom from cardiac events was 96.0% (SE, 0.011) and 79.1% (SE, 0.030), respectively. Predictors for MACE within 1 year were American Society of Anesthesiologists (ASA) score of III or IV (odds ratio [OR], 3.17; 95% confidence interval [CI], 1.52-6.59) and larger abdominal aortic diameter (OR, 1.04; 95% CI, 1.01-1.08). A history of atrial fibrillation (OR, 0.14; 95% CI, 0.03-0.60) was a negative predictor factor. Predictors for MACE through 5 years were a history of heart failure (OR, 4.10; 95% CI 1.36-12.32) and valvular heart disease (OR, 2.31; 95% CI, 0.97-5.51), American Society of Anesthesiologists score of 3 or 4 (OR, 1.66; 95% CI, 0.96-2.88), and older age (OR, 1.04; 95% CI, 1.01-1.08). CONCLUSIONS: MACE is a common complication during the first 5 years after elective EVAR. Cardiac diseases at baseline are strong predictors for long-term MACE and potentially helpful in optimizing future postoperative long-term follow-up.

AIMS: TeleCheck-AF is a multicentre international project initiated to maintain care delivery for patients with atrial fibrillation (AF) during COVID-19 through teleconsultations supported by an on-demand photoplethysmography-based heart rate and rhythm monitoring app (FibriCheck®). We describe the characteristics, inclusion rates, and experiences from participating centres according the TeleCheck-AF infrastructure as well as characteristics and experiences from recruited patients. METHODS AND RESULTS: Three surveys exploring centre characteristics (n = 25), centre experiences (n = 23), and patient experiences (n = 826) were completed. Self-reported patient characteristics were obtained from the app. Most centres were academic (64%) and specialized public cardiology/district hospitals (36%). Majority of the centres had AF outpatient clinics (64%) and only 36% had AF ablation clinics. The time required to start patient inclusion and total number of included patients in the project was comparable for centres experienced (56%) or inexperienced in mHealth use. Within 28 weeks, 1930 AF patients were recruited, mainly for remote AF control (31% of patients) and AF ablation follow-up (42%). Average inclusion rate was highest during the lockdown restrictions and reached a steady state at a lower level after easing the restrictions (188 vs. 52 weekly recruited patients). Majority (>80%) of the centres reported no problems during the implementation of the TeleCheck-AF approach. Recruited patients [median age 64 (55-71), 62% male] agreed that the FibriCheck® app was easy to use (94%). CONCLUSION: Despite different health care settings and mobile health experiences, the TeleCheck-AF approach could be set up within an extremely short time and easily used in different European centres during COVID-19.

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.

AIMS: In patients with atrial fibrillation (AF), echocardiographic tissue velocity imaging (TVI) enables assessment of electrical and structural remodelling by measuring, respectively, the AF cycle length (AFCL-TVI) and the atrial fibrillatory wall motion velocity (AFV-TVI). We investigated the clinical and echocardiographic correlates of atrial remodelling assessed by TVI. METHODS AND RESULTS: We studied 215 patients presenting with AF. In all patients, we measured the AFCL-TVI and the AFV-TVI in the left atrium. Standard baseline characteristics were recorded. We divided patients by median value of AFV-TVI and AFCL-TVI to evaluate the determinants of atrial remodelling. A low AFV-TVI was related with a longer median duration of the current AF episode, a higher prevalence of significant mitral regurgitation and a thicker left ventricle (LV). Multivariate analysis revealed that a low AFV-TVI was independently associated with a longer median duration of the current AF episode [OR 0.09 (95% CI 0.03-0.027); P < 0.001]. Univariately, a short AFCL-TVI was associated with a long median duration of the current AF episode, the use of anti-arrhythmic drugs, a lower LV ejection fraction (LVEF) and a smaller left atrial volume index (LAVI). Multivariate analysis revealed that LVEF [OR 1.48 (95% CI 1.09-2.01); P = 0.013] and LAVI [OR 1.37 (95% CI 1.08-1.74); P = 0.010] were independently associated with AFCL-TVI. CONCLUSION: This study investigated the clinical and echocardiographic correlates of atrial remodelling assessed by TVI. The AFV-TVI is reduced in patients with a long AF duration and who have mitral regurgitation. In addition, the AFCL is long if LAVI is high and LVEF preserved. Tissue velocity imaging parameters measured during AF may be helpful to characterize the degree of atrial remodelling and optimize treatment.

INTRODUCTION: Both the prevalence of atrial fibrillation (AF) and its subsequent use of direct oral anticoagulants (DOACs) are rapidly increasing in patients of older age. In the absence of contra-indications, guidelines advocate anticoagulation based on the CHA2DS2-VASc score for all AF patients aged 75 and above. However, some practitioners are hesitant to prescribe anticoagulants to older and frail patients due to perceived elevated bleeding risks. This review delves into the comparative treatment outcomes of DOACs versus vitamin K antagonists (VKAs) in older patients with AF, particularly focusing on those of advanced age, frailty, increased risk of falling, chronic kidney disease (CKD), or with a history of major bleeding. Additionally, considerations on the use of off-label DOAC doses, the role of left atrial appendage (LAA) closure and future developments in factor XIa-inhibitors will be discussed. RESULTS: While strong evidence supports the use of DOACs in the vital older patients with nonvalvular AF, it remains scant in frail patient groups. There is some evidence from non-randomized studies suggesting that the effect of DOACs compared with VKAs is consistent between frail and nonfrail patients. However, recent findings from a single randomized trial showed increased bleeding risks but comparable thromboembolic outcomes in frail individuals switching from VKAs to DOACs. In patients with an increased risk of falling, data suggest no relevant interaction of increased risk of falling on the effectiveness and safety of DOACs compared with warfarin. Resuming oral anticoagulants in patients with Af after major bleeding seems to be beneficial. Off-label low-dose DOAC is often prescribed to patients who were underrepresented in larger randomized trails because of an elevated risk of bleeding or overexposure to DOACs, but its effect on clinical outcomes remains uncertain. CONCLUSIONS: DOACs are the recommended oral anticoagulant for vital older patients with AF. The scarcity of data backing DOAC use in frail individuals, those with renal impairments, or significant bleeding history underscores the necessity for further investigation. However, existing evidence suggests at least similar effectiveness and safety and potential benefits for DOACs in these patient subsets. Therefore, there is no reason to suggest these patients should be treated differently than the established guidelines regarding anticoagulation.
RESUMO
AIMS: Despite clear guideline recommendations for initiating four drug classes in all patients with heart failure (HF) with reduced ejection fraction (HFrEF) and the availability of rapid titration schemes, information on real-world implementation lags behind. Closely following the 2021 ESC HF guidelines and 2023 focused update, the TITRATE-HF study started to prospectively investigate the use, sequencing, and titration of guideline-directed medical therapy (GDMT) in HF patients, including the identification of implementation barriers. METHODS AND RESULTS: TITRATE-HF is an ongoing long-term HF registry conducted in the Netherlands. Overall, 4288 patients from 48 hospitals were included. Among these patients, 1732 presented with de novo, 2240 with chronic, and 316 with worsening HF. The median age was 71 years (interquartile range [IQR] 63-78), 29% were female, and median ejection fraction was 35% (IQR 25-40). In total, 44% of chronic and worsening HFrEF patients were prescribed quadruple therapy. However, only 1% of HFrEF patients achieved target dose for all drug classes. In addition, quadruple therapy was more often prescribed to patients treated in a dedicated HF outpatient clinic as compared to a general cardiology outpatient clinic. In each GDMT drug class, 19% to 36% of non-use in HFrEF patients was related to side-effects, intolerances, or contraindications. In the de novo HF cohort, 49% of patients already used one or more GDMT drug classes for other indications than HF. CONCLUSION: This first analysis of the TITRATE-HF study reports relatively high use of GDMT in a contemporary HF cohort, while still showing room for improvement regarding quadruple therapy. Importantly, the use and dose of GDMT were suboptimal, with the reasons often remaining unclear. This underscores the urgency for further optimization of GDMT and implementation strategies within HF management.

Heart failure (HF) is a common and growing health problem with high morbidity and mortality rates. Thromboembolism is a major contributor to the poor prognosis of HF patients. HF independently increases the risk of thromboembolism, and the high incidence of atrial fibrillation (AF) in HF patients further adds to the risk of thromboembolic events. The reviewed evidence for the efficacy of anticoagulation in HF patients shows a potential preventive effect of oral anticoagulation in thromboembolism-in particular, risk reduction for stroke-but this is offset by an increased risk of major bleeding. However, given the inhomogeneity of the HF cohorts, the diagnosis of AF warranting oral anticoagulation, the increasing awareness of the potential of bleeding risk assessment, and the advantages of the new oral anticoagulants, the future of thromboembolic prevention in HF patients could very well be brighter than it appears and help improve outcomes for this large group of patients.

AIMS: The management of patients with atrial fibrillation (AF) is often inadequate due to deficient adherence to the guidelines. A nurse-led AF clinic providing integrated chronic care to improve guideline adherence and activate patients in their role, may effectively reduce morbidity and mortality but such care has not been tested in a large randomized trial. Therefore, we performed a randomized clinical trial to compare the AF clinic with routine clinical care in patients with AF. METHODS AND RESULTS: We randomly assigned 712 patients with AF to nurse-led care and usual care. Nurse-led care consisted of guidelines based, software supported integrated chronic care supervised by a cardiologist. The primary endpoint was a composite of cardiovascular hospitalization and cardiovascular death. Duration of follow-up was at least 12 months. Adherence to guideline recommendations was significantly better in the nurse-led care group. After a mean of 22 months, the primary endpoint occurred in 14.3% of 356 patients of the nurse-led care group compared with 20.8% of 356 patients receiving usual care [hazard ratio: 0.65; 95% confidence interval (CI) 0.45-0.93; P= 0.017]. Cardiovascular death occurred in 1.1% in the nurse-led care vs. 3.9% in the usual care group (hazard ratio: 0.28; 95% CI: 0.09-0.85; P= 0.025). Cardiovascular hospitalization amounted (13.5 vs. 19.1%, respectively, hazard ratio: 0.66; 95% CI: 0.46-0.96, P= 0.029). CONCLUSION: Nurse-led care of patients with AF is superior to usual care provided by a cardiologist in terms of cardiovascular hospitalizations and cardiovascular mortality. Trial registration information: Clinicaltrials.gov identifier number: NCT00391872.

Background: Despite ongoing digital and technological developments, incorporation of new developments in outpatient care tends to be slow. Regarding an increasing demand for outpatient care, digitalization of health care carries the potential of a much needed more efficient and patient-oriented system. Objective: To optimize classic face-to-face outpatient clinic follow-up consultations and evaluate the added value of an upfront digital consult preparation (DCP). Methods: A cross-sectional observational study was conducted at Rijnstate Hospital (Arnhem, the Netherlands) among all consecutive patients, 18 years or older, who visited the Cardiology (in June 2021) or Neurology (in September 2021) outpatient clinic. All received a DCP survey before their scheduled outpatient clinic appointment, containing three questions regarding their upcoming visit. In addition, the involved health care providers were approached by using a questionnaire to share their experience regarding the DCP. Data concerning the experience of patients and health care providers was anonymous and gathered using Qualtrics.com. Results: All 25 involved health care providers (12 cardiologists, 13 neurologists) provided feedback. According to the health care providers DCP decreased the workload and improved theirs and patients' preparation. In total, 785 of 1626 (48.3%) patients filled-in the DCP before their appointment within a predetermined period. Only 4% of the patients wanted to change or cancel the consultation. A total of 122 of the 300 (40.1%) patients approached, filled-in a questionnaire to reflect on the DCP. Patients experienced DCP as an improvement of consultation, more time-efficient, increasing patients' and health care providers' preparation, increasing a feeling of acknowledgement and improving co-decision on type of consultation. The DCP did not attribute to co-deciding on treatment. Conclusion: DCP was perceived as an improvement of the standard outpatient care by both health care providers and patients with automated integration into the electronic patient record being of key importance.
RESUMO
In patients with short episodes of clinical, non-triggered AF is the evidence for long-term anticoagulation based on the CHA2DS2-VASc score strong. In situations where a temporary trigger for AF is observed (e.g. after surgery or an infection), or when AF is only detected on a cardiac implantable electronic device (CIED) or smartwatch, the evidence for anticoagulation is less well established. Despite the short duration of the AF episode(s), both patients with subclinical or triggered AF are often at an inherently increased risk of stroke or thromboembolism. In some of these cases long-term anticoagulation can be considered, especially when other cardiovascular risk factors are present. Important considerations when deciding to start with long-term anticoagulation are the individually estimated risk of thrombosis and bleeding, the implementation of shared decision making, and the optimization of the overall cardiovascular risk management.

Up to 45% of patients who underwent percutaneous coronary intervention (PCI) may have a high bleeding risk (HBR), depending on the bleeding risk definition.1 This condition is often associated with an enhanced risk of thrombotic events with a negative impact on short- and long-term outcomes,2-8 making the choice of an appropriate antithrombotic regimen after PCI particularly challenging. Advances in stent technologies, in which the introduction of newer generations of thinner strut drug-eluting stents (DES), have significantly reduced the rate of thrombotic complications and may justify a shorter dual antiplatelet therapy (DAPT) duration. Both in vitro and in vivo studies have shown that local hemodynamic factors may critically affect the natural history of atherosclerosis. Strut thickness correlates with flow disturbances and endothelial shear stress. Flow separation within struts determines areas of recirculation with low endothelial shear stress which promotes local concentration of activated platelets.9 By mitigating inflammation, vessel injury, and neointimal proliferation, thin and streamlined struts have been associated with faster vascular healing and re-endothelization and have resulted in lower rates of thrombotic events after PCI.10,11 The use of thin strut and ultra-thin strut stents may lead to a favorable trade-off in bleeding and ischemic events in patients with HBR. However, dedicated studies evaluating the performance of thin strut versus ultrathin strut stents in patients with HBR are lacking.
RESUMO
OBJECTIVES: To investigate the underprescription of oral anticoagulation (OAC) in individual atrial fibrillation (AF) patients in primary care. SETTING: Screening of patient records in 39 participating general practitioners (GPs) across the Netherlands. PARTICIPANTS: We screened 101 207 patient records identifying 2375 non-valvular AF patients. METHODS: Using electronic patient files, we were able to screen the entire GP population for AF, CHA2DS2-VASc stroke risk scores, and the use of guidelines recommended OAC prescription. In case of a deviation from guidelines recommended OAC prescription, we checked the electronic patient file for any documented reason. Additionally, 6 weeks following the screening, we asked all GPs to provide information on any actions taken for the underprescribed patients. RESULTS: We found a mean CHA2DS2-VASc score of 3.2. OAC prescription consisted of direct OAC in 1342/1984 (68%) and vitamin K-antagonists in the remainder of patients. OAC underprescription was present in 93/944 (9.9%) females and 101/1374 (9.7%) in males, respectively. In 111/146 (76.0%) of the underprescribed AF patients, no reason to withhold OAC was reported. Reported reasons to withhold OAC were patient refusal (n=10), cardiologist advice (n=7) and high risk of bleeding (n=7). Data regarding actions following the identification of OAC underprescription were available for 92/194 (47%) of the OAC underprescribed cases. After consultation OAC was initiated in 9/92 (10%) only. CONCLUSIONS: In this large Dutch study among GPs, we observed 9.8% underprescription of OAC in AF patients. In 76% of the AF patients lacking a prescription for OAC, no documentation for deviating from the guidelines was found. Only in a minority of cases detection of OAC underprescription lead to OAC initiation.

OBJECTIVE: Patients with acute coronary syndrome (ACS) remain at high risk for recurrent ischaemic and bleeding events during follow-up. Our study aimed to quantify and compare the impact of these adverse events on quality of life (QoL). METHODS: Data from patients with ACS prospectively enrolled in the FORCE-ACS registry between January 2015 and December 2019 were used for this study. The primary ischaemic and bleeding events of interest were hospital readmission for ACS and Bleeding Academic Research Consortium type 2 or 3 bleeding during 12 months follow-up. QoL was measured using the EQ-5D Visual Analogue Scale (VAS) score and the 12-item Short Form Survey version 2 derived Physical Component Summary (PCS) and Mental Health Component Summary (MCS) scores at 12 months follow-up. RESULTS: In total, 3339 patients (mean age 66.8 years, 27.9% women) were included. During follow-up, ischaemic events occurred in 202 patients (6.0%) and bleeding events in 565 patients (16.9%). After adjustment for demographic and clinical characteristics, ischaemic events remained independently associated with lower QoL regardless of metric used. Bleeding was also independently associated with lower EQ-5D VAS and PCS scores, but not with a lower MCS score. The QoL decrement associated with ischaemic events was numerically larger than the decrement associated with bleeding. CONCLUSIONS: Ischaemic and bleeding events remain prevalent and are independently associated with lower QoL at 12 months follow-up in patients previously admitted for ACS. The incidence and impact of these adverse events should be considered when balancing individual ischaemic and bleeding risks.

AIMS: The aim of this TeleCheck-AF sub-analysis was to evaluate motivation and adherence to on-demand heart rate/rhythm monitoring app in patients with atrial fibrillation (AF). METHODS AND RESULTS: Patients were instructed to perform 60 s app-based heart rate/rhythm recordings 3 times daily and in case of symptoms for 7 consecutive days prior to teleconsultation. Motivation was defined as number of days in which the expected number of measurements (≥3/day) were performed per number of days over the entire prescription period. Adherence was defined as number of performed measurements per number of expected measurements over the entire prescription period.Data from 990 consecutive patients with diagnosed AF [median age 64 (57-71) years, 39% female] from 10 centres were analyzed. Patients with both optimal motivation (100%) and adherence (≥100%) constituted 28% of the study population and had a lower percentage of recordings in sinus rhythm [90 (53-100%) vs. 100 (64-100%), P < 0.001] compared with others. Older age and absence of diabetes were predictors of both optimal motivation and adherence [odds ratio (OR) 1.02, 95% coincidence interval (95% CI): 1.01-1.04, P < 0.001 and OR: 0.49, 95% CI: 0.28-0.86, P = 0.013, respectively]. Patients with 100% motivation also had ≥100% adherence. Independent predictors for optimal adherence alone were older age (OR: 1.02, 95% CI: 1.00-1.04, P = 0.014), female sex (OR: 1.70, 95% CI: 1.29-2.23, P < 0.001), previous AF ablation (OR: 1.35, 95% CI: 1.03-1.07, P = 0.028). CONCLUSION: In the TeleCheck-AF project, more than one-fourth of patients had optimal motivation and adherence to app-based heart rate/rhythm monitoring. Older age and absence of diabetes were predictors of optimal motivation/adherence.

AIMS: In atrial fibrillation (AF) cardioversion is the cornerstone of the rhythm management strategy despite the lack of contemporary data on acute and long-term success. We aim to describe present-day cardioversion of AF and identify characteristics associated with immediate and long-term outcome. METHODS AND RESULTS: Based on the 5333 AF patients enrolled in the multi-centre prospective Euro Heart Survey on AF we selected the 1801 patients undergoing cardioversion at enrolment. Sinus rhythm (SR) was restored in 630 of 712 (88%), 458 of 643 (71%), and 333 of 446 (75%) (P< 0.001) of the electrical (ECV), intravenous (ivCCV), and oral (oCCV) chemical cardioversions, respectively, at the cost of few (4.2%) major complications. In multivariate analysis, absence of chronic obstructive pulmonary disease (COPD) (P< 0.001), presence of paroxysmal AF (PAF) (P= 0.013), and use of biphasic waveform (P= 0.018) were predictors of successful ECV. For ivCCV PAF (P< 0.001), absence of valvular heart disease (P= 0.004), and heart failure (P= 0.009), the presence of hypertension (P= 0.018) and coronary artery disease (P= 0.007) were predictive. Success of oCCV was driven by PAF (P< 0.001) and a smaller left atrial dimension (P= 0.001). At 1-year follow-up 893 of 1271 (70%) patients were in SR. Multivariate analysis revealed PAF (P< 0.001), shorter total AF history (P< 0.001), continuous use of Class Ic drugs or amiodarone during follow-up (P< 0.001), absence of COPD (P= 0.003), younger age (P= 0.004), and smaller left atrial dimension (P= 0.005) as independent predictors of SR at 1-year follow-up. CONCLUSIONS: Contemporary cardioversion of AF is routinely successfully and safely performed with a high proportion of patients in SR at 1-year follow-up.

AIMS: An age of 60 years is often used as cut-off for the diagnosis of idiopathic atrial fibrillation (AF). We investigated the importance of age and atrial size in patients with idiopathic AF and AF patients with isolated hypertension. METHODS AND RESULTS: Out of 3978 AF patients in the Euro Heart Survey on AF with known follow-up, 119 (3%) patients had idiopathic AF. We disregarded age and atrial size when selecting idiopathic AF patients since the atria may enlarge by AF itself. For comparison, we selected 152 patients with isolated hypertension from the database. A total of 57 (48%) of the patients were older than 60 years. Persistent or permanent AF was more prevalent in the older idiopathic AF patients (34% in the age <60 vs. 66% in the age >60 years group, P= 0.002) but mean duration of known AF did not differ between these groups [310 days (inter-quartile range, IQR) 60-1827) vs. 430 days (IQR 88-1669), P= 0.824]. Left atrial size did not differ significantly in relation to age (1.50 ± 0.29 mm/kg/m² in the age <60 vs. 1.56 ± 0.31 mm/kg/m² in the age >60 years group, P= 0.742). Only two paroxysmal AF patients progressed to permanent AF. No cardiovascular events occurred during the 1-year follow-up. In contrast, strokes occurred in five patients (6%) with isolated hypertension despite similar clinical profile and comparable atrial size as idiopathic AF patients. CONCLUSION: Idiopathic AF may present at advanced age and is even then not associated with significant atrial enlargement, AF progression, or an adverse short-term prognosis. In contrast, elevated blood pressure even when found in the absence of significant atrial remodelling, seems of prognostic importance.

We performed a systematic review of the available evidence on the relationship between the individual clinical, echocardiographic and laboratory characteristics of patients with atrial fibrillation (AF) and the risk of stroke. A systematic review was also performed of all published stroke risk stratification models, as well as the accuracy of their discriminative ability between risk strata. Third, we reviewed the literature on cost-effectiveness analyses with oral anticoagulation in AF. From the systematic review on stroke risk factors, a prior stroke or transient ischemic attack (15/16 studies positive, risk ratio [RR] 2.86), hypertension (11/20 studies positive, RR 2.27), aging (9/13 studies positive, RR 1.46 per decade increase), structural heart disease (9/13 studies positive, RR 2.0) and diabetes (9/14 studies positive, RR 1.62) were found to be good independent predictors of stroke. Supportive evidence was found for sex (8/22 studies positive, RR 1.67), vascular disease (6/17 studies positive, RR 2.61) and heart failure (7/18 studies positive, RR 1.85). The various risk stratification schemes classified variable proportions as low, moderate and high risk, but the CHA(2)DS(2)-VASc score classified the smallest proportion of patients as 'low risk'. Anticoagulation with vitamin K antagonists and dabigatran is cost-effective in patients at high risk of stroke, but not in patients without any other stroke risk factor beside AF. Continued efforts are warranted to improve the antithrombotic management of AF patients to identify, and challenge, risk factors and refine risk stratification models in order to realize an individualized tailored, risk factor-based approach.
