ABSTRACT: Background
The 4S-AF scheme and the ABC pathway for integrated care have been proposed to better characterize and treat patients with atrial fibrillation (AF). We aimed to evaluate the assessment of the 4S-AF scheme and ABC pathway in Chinese AF patients.Methods
The ChiOTEAF is a prospective, observational, multicentre registry. Consecutive AF patients from 44 centres across 20 Chinese provinces with available 1-year follow-up data were included.Results
A total of 6419 patients were included, median age 76 years (interquartile range 67-83; 39.1% female). Of these, 3503 (59.8%) patients were not characterized using the 4S-AF scheme and not management according to the ABC pathway (group 1); 1795 (28.0%) were characterized according to the 4S-AF scheme but ABC pathway non-adherent or vice versa (group 2); and 1121 (17.4%) characterized according to the 4S-AF scheme and were ABC pathway adherent (group 3). As compared with group 1, group 2 and group 3 were independently associated with lower odds of the composite endpoint of all-cause death/any thromboembolic event, with the greatest benefit observed in group 3 (OR: 0.19; 95% CI 0.12-0.31) [for group 2: OR: 0.28; 95% CI 0.20-0.37]. Similar results were observed for all-cause death (group 2: OR: 0.18; 95% CI 0.12-0.27; group 3: OR: 0.14; 95% CI 0.07-0.25).Conclusions
In a contemporary real-word cohort of Chinese AF patients, it is feasible to characterize and manage AF patients using the novel 4S-AF scheme and ABC pathway for integrated care. The use of both these tools is associated with improved clinical outcomes.

Project description:AimsThe recent 4S-AF (scheme proposed by the 2020 ESC AF guidelines to address stroke risk, symptom severity, severity of AF burden and substrate of AF to provide a structured phenotyping of AF patients in clinical practice to guide therapy and assess prognosis) scheme has been proposed as a structured scheme to characterize patients with atrial fibrillation (AF). We aimed to assess whether the 4S-AF scheme predicts AF progression in patients with self-terminating AF.Methods and resultsWe analysed 341 patients with self-terminating AF included in the well-phenotyped Reappraisal of Atrial Fibrillation: Interaction between HyperCoagulability, Electrical remodelling, and Vascular Destabilization in the Progression of AF (RACE V) study. Patients had continuous monitoring with implantable loop recorders or pacemakers. AF progression was defined as progression to persistent or permanent AF or progression of self-terminating AF with >3% burden increase. Progression of AF was observed in 42 patients (12.3%, 5.9% per year). Patients were given a score based on the components of the 4S-AF scheme. Mean age was 65 [interquartile range (IQR) 58-71] years, 149 (44%) were women, 103 (49%) had heart failure, 276 (81%) had hypertension, and 38 (11%) had coronary artery disease. Median CHA2DS2-VASc (the CHA2DS2-VASc score assesses thromboembolic risk. C, congestive heart failure/left ventricular dysfunction; H, hypertension; A2, age ≥ 75 years; D, diabetes mellitus; S2, stroke/transient ischaemic attack/systemic embolism; V, vascular disease; A, age 65-74 years; Sc, sex category (female sex)) score was 2 (IQR 2-3), and median follow-up was 2.1 (1.5-2.6) years. The average score of the 4S-AF scheme was 4.6 ± 1.4. The score points from the 4S-AF scheme did not predict the risk of AF progression [odds ratio (OR) 1.1 95% CI 0.88-1.41, C-statistic 0.53]. However, excluding the symptoms domain, resulting in the 3S-AF (4S-AF scheme without the domain symptom severity, only including stroke risk, severity of AF burden and substrate of AF) scheme, predicted the risk of progression (OR 1.59 95% CI 1.15-2.27, C-statistic 0.62) even after adjusting for sex and age.ConclusionsIn self-terminating AF patients, the 4S-AF scheme does not predict AF progression. The 3S-AF scheme, excluding the symptom domain, may be a more appropriate score to predict AF progression.Trial registration numbersClinicaltrials.gov NCT02726698 for RACE V.

Project description:BackgroundThe Atrial Fibrillation Better Care (ABC) has been proposed as an integrated approach to improve management in patients with atrial fibrillation (AF), based on 3 pillars: "A" Avoid stroke with Anticoagulation; "B" Better symptoms control; "C" Cardiovascular risk-factor and comorbidities management.ObjectivesThis study sought to investigate the association with outcomes of ABC adherence in the prospective multinational Asia-Pacific Heart Rhythm Society (APHRS) Atrial Fibrillation registry.MethodCox-regression analyses adjusted for age, sex, CHA2DS2-VASc score, paroxysmal AF, chronic obstructive pulmonary disease, chronic kidney disease, cancer, dyslipidemia, and dementia were performed to investigate the association with outcomes. Primary outcome was a composite of all-cause death, any thromboembolic events, acute coronary syndrome or percutaneous interventional procedures, and advancing heart failure.ResultsOf the 4,013 included patients with AF (mean age 68 ± 12 years; 34.4% female); 38.6% were adherent to all 3 main ABC pillars. After 1 year of follow-up, adherence to the ABC pathway was associated with a low incidence of composite outcome (4.0% vs 8.5%, P < 0.001), all-cause and cardiovascular death, and advancing heart failure. On Cox regression analysis, ABC adherence was associated with a lower risk of primary outcome (HR: 0.72; 95% CI: 0.53-0.97), with risk reduction progressively higher with a higher number of ABC criteria attained. No significant interaction in the association was seen according to the different geographic areas (Pint = 0.217).ConclusionsIn a large contemporary cohort of Asian patients with AF, adherence to ABC pathway was associated with a reduction of the risk for adverse outcomes.

Project description:Growth differentiation factor 15 (GDF-15) is a biomarker independently associated with bleeding and death in anticoagulated patients with atrial fibrillation (AF). GDF-15 is also used as one component in the more precise biomarker-based ABC (age, biomarkers, clinical history)-AF-bleeding and ABC-AF-death risk scores. Data from large trials indicate a geographic variability in regard to overall outcomes, including bleeding and mortality risk. Our aim was to assess the consistency of the association between GDF-15, ABC-AF-bleeding score and ABC-AF-death score, with major bleeding and death, across world geographic regions. Data were available from 14 767 patients with AF from the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial and 8651 patients with AF from the Randomized Evaluation of Long-Term Anticoagulation Therapy (RE-LY) trial in this cohort study. GDF-15 was analysed from plasma samples obtained at randomisation. The geographical consistency of the associations between outcomes and GDF-15, ABC-AF-bleeding score and ABC-AF-death scores were assessed by Cox-regression models including interactions with predefined geographical region. GDF-15 and the ABC-AF-bleeding score were associated with major bleeding in both trials across regions (p<0.0001). Similarly, GDF-15 and the ABC-AF-death score were associated with all-cause mortality in both trials across regions (p<0.0001). Overall, the association between GDF-15, the ABC-AF-bleeding score and ABC-AF-death risk score with major bleeding and death was consistent across regions in both ARISTOTLE and the RE-LY trial cohorts. The ABC-AF-bleeding and ABC-AF-death risk scores were consistent regarding discriminative ability when comparing geographic regions in both trial cohorts. The C-indices ranged from 0.649 to 0.760 for the ABC-AF-bleeding and from 0.677 to 0.806 for the ABC-AF-death score by different geographic regions. In patients with AF on anticoagulation, GDF-15 and the biomarker-based ABC-AF-bleeding and ABC-AF-death risk scores are consistently associated with respectively increased risk of major bleeding and death and have similar prognostic value across world geographic regions.

Project description:IntroductionA multidisciplinary approach is needed for the management of atrial fibrillation (AF) in which the patient has a central role. Smart devices create opportunities to improve AF management. This paper aimed to evaluate the in-house developed AF-EduApp application on its usability, satisfaction, and communication effectiveness with the care team.MethodsDuring a multicenter, prospective randomized controlled trial, 153 AF patients were included in the AF-EduApp study, with a minimum follow-up of 12 months and a maximum follow-up of 15 months if taking oral anticoagulation (OAC). The AF-EduApp contains six main modules: Questionnaires, Education, Measurement data entry, Medication overview with reminders, Appointments, and Communication with the care team. The App focuses on four main goals: (1) to improve AF knowledge, (2) to increase self-care capabilities, (3) electronic monitoring to improve therapy adherence to OAC, and (4) communication with the care team. Patients unable to use the AF-EduApp were assigned to a no-App control group (n = 41) without intervention comparable to the standard care group (SC, n = 346) of the AF-EduCare study.ResultsA total of 152 patients effectively used the App during a mean follow-up of 386.8 ± 108. 1 days (one included patient could not install the application due to an iPhone from the United States). They opened the application on average on 130.1 ± 144.7 days. Of the 109 patients still in follow-up after 12 months (i.e. patients who did not withdraw and on OAC), 90 patients (82.6%) actively used the application at least one day in the next 41 days. The Measurement module was the most used, with a median of used days over the total available days of 6.4%. A total of 75 App patients (49.3%) asked questions, mostly clinical-related questions (e.g. medication use, or actionability on clinical entered parameters). A mean score of 8.1 ± 1.7 about the "perceived quality of follow-up in the past year" was given by the App ITT patients, compared to a score of 7.7 ± 2.0 by the SC group (P = .072). Patients who used the App were more attracted to future follow-up with an application compared to patients who would be capable of using the application of the SC group (31.6% vs. 12.5%; P < .001).ConclusionThis study showed a positive attitude towards using a mobile application, with AF patients using the application one-third of the available days. Patients used the App most for entering measured parameters, and to contact the care team.

Project description:BackgroundClinical 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.MethodsFrom 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.ResultsAmong 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.ConclusionsAn 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.

Project description:Atrial fibrillation (AF) is associated with substantially increased risk of cardiovascular events and overall mortality. The Atrial fibrillation Better Care (A-Avoid stroke, B-Better symptom management, C-Cardiovascular and comorbidity risk management) pathway provides a simple and comprehensive approach for integrated AF therapy. This study's goals were to evaluate the ABC pathway compliance and determine the main gaps in AF management in the Middle East population, and to assess the impact of ABC pathway adherence on the all-cause mortality and composite outcome in AF patients. 2021 patients (mean age 57; 52% male) from the Gulf SAFE registry were studied. We evaluated: A-appropriate implementation of OACs according to CHA2DS2-VASc score; B-symptom control according to European Heart Rhythm Association (EHRA) symptom scale; C-proper cardiovascular comorbidities management. The primary endpoints were the composite cardiovascular outcome (ischemic stroke or systemic embolism, all-cause death and cardiovascular hospitalization) and all-cause mortality. One-hundred and sixty-eight (8.3%) patients were optimally managed according to adherence with the ABC pathway. Over the one-year follow up (FU), there were 578 composite outcome events and 224 deaths. Patients managed with integrated care had significantly lower rates for the composite outcome and mortality comparing to non-ABC group (20.8% vs. 29.3%, p = 0.02 and 7.3% vs. 13.1%, p = 0.033, respectively). On multivariable analysis, ABC compliance was independently associated with reduced risk of composite outcome (HR 0.53; 95% CI 0.36-0.8, p = 0.002) and death (HR 0.46; 95% CI 0.25-0.86, p = 0.015). Integrated ABC pathway adherent care resulted in the reduced composite outcome and all-cause mortality in AF patients from Middle East, highlighting the necessity of promoting comprehensive holistic and integrated care management of AF.

Project description:BackgroundBALKAN-AF evaluated patterns of atrial fibrillation (AF) management in real-world clinical practice in the Balkans. The objectives were: to assess the proportion of patients with first-diagnosed AF in the BALKAN-AF cohort and to compare the management of patients with newly-diagnosed AF and those with previously known AF in clinical practice.MethodsConsecutive patients from 7 Balkan countries were enrolled prospectively to the snapshot BALKAN-AF survey.ResultsOf 2712 enrolled patients, 2677 (98.7%) with complete data were included. 631 (23.6%) patients had newly-diagnosed AF and 2046 (76.4%) patients had known AF. Patients with newly-diagnosed AF were more likely to be hospitalized for AF and to receive single antiplatelet therapy (SAPT) alone and less likely to receive OACs than those with known AF (all p < 0.001). The use of OAC was not significantly associated with the CHA2DS2-VASc (p = 0.624) or HAS-BLED score (p = 0.225) on univariate analysis. Treatment in capital city, hypertension, dilated cardiomyopathy, mitral valve disease, country of residence or rate control strategy were independent predictors of OAC use, whilst non-emergency centre, treatment by cardiologist, paroxysmal AF, palpitations, symptoms attributable to AF (as judged by physician), mean heart rate and AF as the main reason for hospitalization were independent predictors of rhythm control strategy use.ConclusionsIn BALKAN-AF survey, patients with newly-diagnosed AF were more often hospitalized, less often received OAC and were more likely to receive SAPT alone. The use of OAC for stroke prevention has not been driven by the individual patient stroke risk.

Project description:AimTo evaluate changes in healthcare utilisation and comprehensive packages of care activities and procedures (referred in the Netherlands to as 'diagnose-behandelcombinatie (DBC) care products) during the implementation of the TeleCheck-AF approach (teleconsultation supported by app-based heart rate/rhythm monitoring) in a Dutch atrial fibrillation (AF) clinic.Methods and resultsIn the Maastricht University Medical Centre+ AF Clinic, data on healthcare utilisation and DBC care products for patients consulted by both a conventional approach in 2019 and the TeleCheck-AF approach in 2020 were analysed. A patient experience survey was performed. Thirty-seven patients (median age 68 years; 40% women) were analysed. With the conventional approach, 35 face-to-face consultations and 0 teleconsultations were conducted. After the implementation of TeleCheck-AF, the number of face-to-face consultations dropped by 80% (p < 0.001) and teleconsultations increased to 45 (p < 0.001). While 42 electrocardiograms (ECGs) and 25 Holter ECGs or echocardiograms were recorded when using the conventional approach, the number of ECGs decreased by 71% (p < 0.001) and Holter ECGs or echocardiograms by 72% (p < 0.001) with the TeleCheck-AF approach. The emergency department patient presentations showed no statistically significant change (p = 0.33). Overall, 57% of medium-weight DBC care products were changed to light-weight ones during implementation of the TeleCheck-AF approach. Patient satisfaction with the TeleCheck-AF approach was high.ConclusionThe implementation of TeleCheck-AF led to a change in healthcare utilisation, a change from medium-weight to light-weight DBC care products and a reduction in patient burden. These results created the basis for a new reimbursement code for the TeleCheck-AF approach in the Netherlands.

Project description:BackgroundAtrial fibrillation (AF) is a complex disease associated with comorbidities and adverse outcomes. The Atrial fibrillation Better Care (ABC) pathway has been proposed to streamline the integrated and holistic approach to AF care.ObjectivesThis study sought to evaluate patients' characteristics, incidence of adverse events, and impact on outcomes with ABC pathway-adherent management.MethodsThe study included consecutive AF patients enrolled in the nationwide, ChioTEAF registry (44 centers, 20 Chinese provinces from October 2014 to December 2018), with available data to evaluate the ABC criteria and on the 1-year follow-up.ResultsA total of 3,520 patients (mean age 73.1 ± 10.4 years, 43% female) were included, of which 1,448 (41.1%) were managed as ABC pathway adherent. The latter were younger and had comparable CHA2DS2-VASc and lower HAS-BLED (mean 71.7 ± 10.3 years of age vs 74.1 ± 10.4 years of age; P < 0.01; 3.54 ± 1.60 vs 3.44 ± 1.70; P = 0.10; and 1.95 ± 1.10 vs 2.12 ± 1.20; P < 0.01, respectively) scores compared with ABC-nonadherent patients. At 1-year follow-up, patients managed adherent to the ABC pathway had a lower incidence of the primary composite outcome of all-cause death or any thromboembolic event (1.5% vs 3.6%; P < 0.01) as compared with ABC-nonadherent patients. On multivariate analysis, ABC pathway-adherent care was independently associated with a lower risk of the composite endpoint (OR: 0.51; 95% CI: 0.31-0.84).ConclusionsAdherence to the ABC pathway for integrated care in a contemporary nationwide cohort of Chinese AF patients was suboptimal. Clinical management adherent to the ABC pathway was associated with better outcomes.

Project description:Atrial fibrillation (AF), the most common cardiac arrhythmia, is a major contributor to population mortality and morbidity. The goal of this study is to explore molecular mechanisms of the AF-induced profibrotic remodelling in human atrial fibroblasts (ACFs). Specifically, we assessed single-cell transcriptome of cultured human ACFs treated with calcitonin(CT) or vehicle (from 6 individual patients) and of freshly-isolated ACFs from patients with AF (4 individual patients) vs controls (4 individual patients) (SR). We found that ACF transcriptome was unaltered by CT in cultured ACFs, and identified 5 transcriptional clusters with 23 differentially expressed transcripts in AF in freshly-ioslated ACFs.
