Background: Implementation of the Atrial fibrillation Better Care (ABC) pathway is recommended by guidelines on atrial fibrillation (AF), but the impact of adherence to ABC pathway in patients with cancer is unknown. Objectives: To investigate the adherence to ABC pathway and its impact on adverse outcomes in AF patients with cancer. Methods: Patients enrolled in the EORP-AF General Long-Term Registry were analyzed according to (i) No Cancer; and (ii) Prior or active cancer and stratified in relation to adherence to the ABC pathway. The composite Net Clinical Outcome (NCO) of all-cause death, major adverse cardiovascular events and major bleeding was the primary endpoint. Results: Among 6550 patients (median age 69 years, females 40.1%), 6005 (91.7%) had no cancer, while 545 (8.3%) had a diagnosis of active or prior cancer at baseline, with the proportions of full adherence to ABC pathway of 30.6% and 25.7%, respectively. Adherence to the ABC pathway was associated with a significantly lower occurrence of the primary outcome vs. non-adherence, both in ‘no cancer’ and ‘cancer’ patients [adjusted Hazard Ratio (aHR) 0.78, 95% confidence interval (CI): 0.66–0.92 and aHR 0.59, 95% CI 0.37–0.96, respectively]. Adherence to a higher number of ABC criteria was associated with a lower risk of the primary outcome, being lowest when 3 ABC criteria were fulfilled (no cancer: aHR 0.54, 95%CI: 0.36–0.81; with cancer: aHR 0.32, 95% CI 0.13–0.78). Conclusion: In AF patients with cancer enrolled in the EORP-AF General Long-Term Registry, adherence to ABC pathway was sub-optimal.

Background: The outcome implications of asymptomatic vs. symptomatic atrial fibrillation (AF) in specific groups of patients according to clinical heart failure (HF) and left ventricular ejection fraction (LVEF) need to be clarified. Methods: In a prospective observational study, patients were categorized according to overt HF with LVEF≤40 %, or with LVEF>40 %, or without overt HF with LVEF40 %≤ or > 40 %, as well as according to the presence of asymptomatic or symptomatic AF. Results: A total of 8096 patients, divided into 8 groups according to HF and LVEF, were included with similar proportions of asymptomatic AF (ranging from 43 to 48 %). After a median follow-up of 730 [699 -748] days, the composite outcome (all-cause death and MACE) was significantly worse for patients with asymptomatic AF associated with HF and reduced LVEF vs. symptomatic AF patients of the same group (p = 0.004). On adjusted Cox regression analysis, asymptomatic AF patients with HF and reduced LVEF were independently associated with a higher risk for the composite outcome (aHR 1.32, 95 % CI 1.04-1.69) and all-cause death (aHR 1.33, 95 % CI 1.02-1.73) compared to symptomatic AF patients with HF and reduced LVEF. Kaplan-Meier curves showed that HF-LVEF≤40 % asymptomatic patients had the highest cumulative incidence of all-cause death and MACE (p < 0.001 for both). Conclusions: In a large European cohort of AF patients, the risk of the composite outcome at 2 years was not different between asymptomatic and symptomatic AF in the whole cohort but adverse implications for poor outcomes were found for asymptomatic AF in HF with LVEF≤40 %. © 2023 European Federation of Internal Medicine

The most recent atrial fibrillation (AF) guidelines delivered by European Society of Cardiology (ESC) offer an updated approach to AF management, with the perspective of improved characterization of the arrhythmia, the cardiac substrate and the patients profile in terms of associated risk factors and comorbidities. Recommendations were based on careful scrutiny and assessment of all available evidence with the final aim to offer to practitioners a lower level of uncertainty in the complex process of decision making for patients with AF. The 2020 ESC guidelines on AF propose a paradigm shift in the clinical approach to AF patients, moving from a single-domain AF classification to comprehensive characterization of AF patients. Given the complex nature of AF, an integrated holistic management of AF patients is suggested by the guidelines for improving patients outcomes through the formal introduction of the CC (Confirm AF and Characterize AF) to ABC (Atrial fibrillation Better Care) pathway. In line with this concept, these new guidelines underline the importance of a more comprehensive management of AF patients which should not be limited to simply prescribe oral anticoagulation or decide between a rhythm or rate control strategy. Indeed, each step of the ABC pathway represents one of the pivotal pillars in the management of AF and only a holistic approach has the potential to improve patients’ outcomes. In this review we will discuss the background that supports some of the new recommendations of 2020 ESC guidelines, with important implications for daily management of AF patients. © 2021

Background: Cardiac troponins (cTn) have been reported to be predictors for adverse outcomes in atrial fibrillation (AF), patients, but their actual use is still unclear. Aim: To assess the factors associated with cTn testing in routine practice and evaluate the association with outcomes. Methods: Patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry were stratified into 3 groups according to cTn levels as (i) cTn not tested, (ii) cTn in range (≤99th percentile), (iii) cTn elevated (>99th percentile). The composite outcome of any thromboembolism /any acute coronary syndrome/cardiovascular (CV) death, defined as Major Adverse Cardiovascular Events (MACE) and all-cause death were the main endpoints. Results: Among 10 445 AF patients (median age 71 years, 40.3% females) cTn were tested in 2834 (27.1%). cTn was elevated in 904/2834 (31.9%) and in-range in 1930/2834 (68.1%) patients. Female sex, in-hospital enrollment, first-detected AF, CV risk factors, history of coronary artery disease, and atypical AF symptoms were independently associated with cTn testing. Elevated cTn were independently associated with a higher risk for MACE (Model 1, hazard ratio [HR] 1.74, 95% confidence interval [CI] 1.40–2.16, Model 2, HR 1.62, 95% CI 1.28–2.05; Model 3 HR 1.76, 95% CI 1.37–2.26) and all-cause death (Model 1, HR 1.45, 95% CI 1.21–1.74; Model 2, HR 1.36, 95% CI 1.12–1.66; Model 3, HR 1.38, 95% CI 1.12–1.71). Conclusions: Elevated cTn levels were associated with an increased risk of all-cause mortality and adverse CV events. Clinical factors that might enhance the need to rule out CAD were associated with cTn testing. © 2022 European Federation of Internal Medicine

Background: Chronic kidney disease (CKD) and atrial fibrillation (AF) often coexist, making accurate renal function estimation crucial, typically through equations calculating estimated glomerular filtration rate (eGFR) or creatinine clearance (CrCl). Objective: To compare the concordance and predictive performance of different renal function estimation equations in a European cohort of AF patients. Methods: We analyzed data from AF patients enrolled in a prospective observational European registry. Renal function was estimated using eight formulas: BIS-1, CG, CG-BSA, CKD-EPI, EKFC, FAS, LMR and MDRD. Concordance between formulas was assessed using weighted Cohen's Kappa, while Cox regression and receiver operating characteristic (ROC) curves evaluated their association with outcomes (composite of all-cause death, any coronary revascularization and any thromboembolism). Results: We included 8,506 patients. CKD-EPI demonstrated good to excellent concordance with other formulas, with the lowest concordance with CG (K = 0.607; 95% CI, 0.595-0.618) and the highest with MDRD (K = 0.880; 95% CI, 0.873-0.887). The risk of adverse outcomes increased sharply when renal function dropped below 60 ml/min across all formulas. CG-BSA and CG formulas showed the best discriminative ability for predicting composite outcomes (AUC 0.660, 95% CI 0.644-0.677, and 0.661, 95% CI 0.644-0.678, respectively). Based on integrated discrimination improvement (IDI) analysis, compared to the CKD-EPI equation, the CG and CG-BSA formulas showed significant improvements in sensitivity of 0.9% and 1.1%, respectively Conclusion: Equations for estimating renal function vary in concordance, with potential implications for drug prescription and predicting adverse events. CG and CG-BSA formulas showed superior performance in identifying patients at risk for adverse outcomes. © 2025 The Authors

Background: Clinical complexity is increasingly prevalent among patients with atrial fibrillation (AF). The ‘Atrial fibrillation Better Care’ (ABC) pathway approach has been proposed to streamline a more holistic and integrated approach to AF care; however, there are limited data on its usefulness among clinically complex patients. We aim to determine the impact of ABC pathway in a contemporary cohort of clinically complex AF patients. Methods: From the ESC-EHRA EORP-AF General Long-Term Registry, we analysed clinically complex AF patients, defined as the presence of frailty, multimorbidity and/or polypharmacy. A K-medoids cluster analysis was performed to identify different groups of clinical complexity. The impact of an ABC-adherent approach on major outcomes was analysed through Cox-regression analyses and delay of event (DoE) analyses. Results: Among 9966 AF patients included, 8289 (83.1%) were clinically complex. Adherence to the ABC pathway in the clinically complex group reduced the risk of all-cause death (adjusted HR [aHR]: 0.72, 95%CI 0.58–0.91), major adverse cardiovascular events (MACEs; aHR: 0.68, 95%CI 0.52–0.87) and composite outcome (aHR: 0.70, 95%CI: 0.58–0.85). Adherence to the ABC pathway was associated with a significant reduction in the risk of death (aHR: 0.74, 95%CI 0.56–0.98) and composite outcome (aHR: 0.76, 95%CI 0.60–0.96) also in the high-complexity cluster; similar trends were observed for MACEs. In DoE analyses, an ABC-adherent approach resulted in significant gains in event-free survival for all the outcomes investigated in clinically complex patients. Based on absolute risk reduction at 1 year of follow-up, the number needed to treat for ABC pathway adherence was 24 for all-cause death, 31 for MACEs and 20 for the composite outcome. Conclusions: An ABC-adherent approach reduces the risk of major outcomes in clinically complex AF patients. Ensuring adherence to the ABC pathway is essential to improve clinical outcomes among clinically complex AF patients. © 2022, The Author(s).

Clinical practice in atrial fibrillation (AF) patient management is constantly evolving. In the past 3 years, various new AF guidelines or focused updates have been published, given this rapidly evolving field. In 2019, the American College of Cardiology/American Heart Association published a focused update of the 2014 guidelines. In 2020, both the European Society of Cardiology and the Canadian Cardiovascular Society released their new guidelines. Finally, the most recent guidelines were those published in 2021 by the Asian Pacific Heart Rhythm Society, which updates their 2017 version and the 2021 National Institute for Health and Care Excellence (NICE) guidelines. In the present narrative review, we compare these guidelines, emphasizing similarities and differences in the following mainstay elements of patient care: thromboembolic risk assessment, oral anticoagulants (OACs) prescription, bleeding risk evaluation, and integrated patient management. A formal evaluation of baseline thromboembolic and bleeding risks and their reassessment during follow-up is evenly recommended, although some differences in using risk stratification scores. OACs prescription is highly encouraged where appropriate, and prescription algorithms are broadly similar. The importance of an integrated and multidisciplinary approach to patient care is emerging, aiming to address several different aspects of a multifaceted disease. © 2022

Aims Bleeding risk assessment is recommended in guidelines for the management of atrial fibrillation (AF). The HAS-BLED score was proposed prior to non-vitamin K antagonist oral anticoagulants (NOACs) and it has been suggested that the ORBIT score may be superior in predicting bleeds in NOAC users. We aimed to compare the HAS-BLED and ORBIT scores in contemporary AF patients treated with NOACs. Methods and results We analysed patients enrolled in the ESC-EHRA EORP-AF (EURObservational Research Programme in AF) General Long-Term Registry. HAS-BLED and ORBIT scores were computed based on original schemes. The primary outcome was the occurrence of major bleeding (MB). A total of 3018 patients (median age 70; 39.6% females) were included: median [interquartile range (IQR)] HAS-BLED and ORBIT scores were 1 [1-2] and 1 [0-2], respectively; 356 (11.8%) patients were at high risk for MB using HAS-BLED (≥3) and 123 (4.1%) using ORBIT (≥4). Overall, 60 (2.0%) MB events were recorded, with an incidence of 1.1 per 100 patient-years. Both HAS-BLED and ORBIT were associated with outcome, modestly predicting MB [area under the curve (AUC) 0.653, 95% confidence interval (CI) 0.593-0.714 and AUC 0.601, 95% CI 0.526-0.677, respectively]. Calibration plots showed that both scores were poorly calibrated, particularly the ORBIT score, which showed consistent poorer calibration. Time-dependent reclassification analysis showed a trend towards incorrect lower risk reclassification using ORBIT compared with HAS-BLED. Conclusion In this real-life contemporary cohort of AF patients treated with NOACs, the ORBIT score did not provide reclassification improvement, showing even poorer calibration compared with HAS-BLED. Our findings do not support the preferential use of ORBIT in NOAC-treated AF patients. © The Author(s) 2021.
