Management of atrial fibrillation in older adults.

Most people with atrial fibrillation are older adults, in whom atrial fibrillation co-occurs with other chronic conditions, polypharmacy, and geriatric syndromes such as frailty. Yet most randomized controlled trials and expert guidelines use an age agnostic approach. Given the heterogeneity of aging, these data may not be universally applicable across the spectrum of older adults. This review synthesizes the available evidence and applies rigorous principles of aging science. After contextualizing the burden of comorbidities and geriatric syndromes in people with atrial fibrillation, it applies an aging focused approach to the pillars of atrial fibrillation management, describing screening for atrial fibrillation, lifestyle interventions, symptoms and complications, rate and rhythm control, coexisting heart failure, anticoagulation therapy, and left atrial appendage occlusion devices. Throughout, a framework is suggested that prioritizes patients' goals and applies existing evidence to all older adults, whether atrial fibrillation is their sole condition, one among many, or a bystander at the end of life.

A Predictive Nomogram of In-Hospital Mortality After 48 h for Atrial Fibrillation Patients in the Coronary Care Unit.

BACKGROUND: Patients with atrial fibrillation (AF) suffer a higher risk of death, and it is necessary to develop prediction tools for mortality risk in critically ill patients with AF. This study aimed to develop a novel predictive nomogram of in-hospital mortality after 48 h in the coronary care unit (CCU) for patients with AF. METHODS: We collected information on CCU patients with AF from the "Medical Information Mart for Intensive Care-III" database and developed a nomogram model for predicting the all-cause mortality risk after 48 h in the hospital. Key variables were selected by univariate logistic and least absolute shrinkage and selection operator regression. The independent predictors with p < 0.05 were screened out by multivariate logistic regression. A predictive nomogram was constructed using these independent predictors, and the model calibration and discrimination were evaluated. RESULTS: This study finally enrolled 1248 CCU patients with AF, and the in-hospital mortality was 17% (209/1248). The predictive nomogram was constructed by 13 selected independent predictors, including age, smoking status, acute kidney injury, chronic obstructive pulmonary disease, ventricular arrhythmia, shock, urea, red cell distribution width, leucocytosis, continuous renal replacement therapy, continuous positive airway pressure, anticoagulation, and heart rate. The area under the curve of the nomogram was 0.803 (95% confidence interval 0.771-0.835). The nomogram was verified to have good accuracy and calibration. CONCLUSIONS: This study developed a novel nomogram containing age, acute kidney injury, and heart rate that can be a good predictor of potential in-hospital mortality after 48 h in CCU patients with AF.

Dual-chamber vs. single-chamber pacemaker in patients in sinus rhythm with an atrioventricular block: a nationwide cohort study.

AIMS: In complete atrioventricular block (AVB) with underlying sinus rhythm, it is recommended to implant a dual-chamber pacemaker rather than a single-chamber pacemaker. However, no large-scale study has been able to demonstrate the superiority of this choice on hard clinical criteria such as morbimortality. METHODS AND RESULTS: This retrospective observational study included all patients who received a primary pacemaker implantation in the indication of complete AVB with underlying sinus rhythm in France, based on the national administrative database between January 2013 and December 2022. After propensity score matching, we obtained two groups containing 19 219 patients each. The incidence of all-cause mortality was 9.22%/year for the dual-chamber pacemaker group, compared with 11.48%/year for the single-chamber pacemaker group (hazard ratio (HR) 0.807, P < 0.0001]. Similarly, there was a lower incidence of cardiovascular mortality (HR 0.766, P < 0.0001), heart failure (HR 0.908, P < 0.0001), atrial fibrillation (HR 0.778, P < 0.0001), and ischaemic stroke (HR 0.873, P = 0.008) in the dual-chamber pacemaker group than in the single-chamber pacemaker group. Regarding re-interventions and complications, there were fewer upgrades (addition of atrial lead or left ventricular lead) in the dual-chamber group (HR 0.210, P < 0.0001), but more haematomas (HR 1.179, P = 0.006) and lead repositioning (HR 1.123, P = 0.04). CONCLUSION: In the indication of complete AVB with underlying sinus rhythm, our results are consistent with current recommendations to prefer implantation of a dual-chamber pacemaker rather than a single-chamber pacemaker for these patients. Implantation of a dual-chamber pacemaker is associated with a lower risk of mortality, heart failure, atrial fibrillation, and stroke during follow-up.

Components of the Atrial fibrillation Better Care pathway for holistic care of patients with atrial fibrillation: a win ratio analysis from the COOL-AF registry.

AIMS: Compliance with integrated care based on the Atrial fibrillation Better Care (ABC) pathway has been associated with improved clinical outcomes. The primary objective of this study was to compare clinical outcomes of AF patients according to the compliant status of each component of the ABC pathway in a hierarchical win ratio approach. METHODS AND RESULTS: We studied AF patients in the COOL-AF registry. Each patient was followed every 6 months until 3 years. A win ratio analysis was performed, as not all clinical outcomes are equivalent. The hierarchical outcomes were (1) all-cause death, (2) intracranial haemorrhage (ICH), (3) ischaemic stroke/systemic embolism, (4) non-ICH major bleedings, and (5) acute myocardial infarction or heart failure. We also assessed win ratio and win proportion variance over the follow-up time, and the variations over time. A total of 3405 patients (mean age 67.8 ± 11.3; 41.8% female) were studied. Win ratio of ABC-compliant (all three components) vs. ABC-not-compliant was 1.57 (1.35-1.83), P < 0.001. When adding time in therapeutic range (TTR) data for compliant criteria for those who were on warfarin, the win ratio increased to 2.28 (1.89-2.75), P < 0.001. The A-compliant group (plus TTR data), B-compliant, and C-compliant had the win ratio of 1.81 (1.51-2.12), 1.82 (1.53-2.16), and 1.39 (1.18-1.62), all P < 0.001, compared to not compliant group. CONCLUSION: Management of AF patients according to each component of the ABC pathway is associated with better clinical outcomes compared to those non-compliant to ABC pathway. This finding underscores the importance of a holistic management approach strategy for AF patients.

Risk Factor Management for Patients with Atrial Fibrillation in Home Healthcare.

Atrial fibrillation (AF) is a common and persistent cardiac arrhythmia that impacts morbidity, mortality, disability, quality of life, and healthcare costs. Typically, AF is managed using a three-pillar approach of rate control, rhythm control, and anticoagulation. However, these interventions fail to address the underlying pathophysiological factors that contribute to AF. A compelling body of research expands traditional management by focusing on lifestyle modification to lower the risk of AF incidence, prevalence, progression, and severity. Home healthcare clinicians possess the knowledge and skills to examine and treat a wide range of risk factors that lead to AF, and therefore can substantially reduce incident and persistent AF and facilitate optimal outcomes. This perspective paper presents a clinical paradigm shift by proposing a five-factor Partner, Quantify, Recommend, Support, and Teach (PQRST) framework to support AF risk factor modification in home healthcare. The PQRST framework incorporates a greater focus on patient self-management through education and exercise to reduce incidence, prevalence, progression, and severity of AF.

Safety and efficacy of electric cardioversion in the emergency department: analysis of associated factors according to gender. / Eficacia y seguridad de la cardioversión eléctrica en urgencias: factores asociados y perspectiva de sexo.

OBJECTIVE: To explore the safety and effectiveness of electric cardioversion to treat atrial fibrillation in a hospital emergency department (ED). METHODS: Retrospective observational study in a hospital ED. We reviewed episodes of atrial fibrillation in patients aged 18 years orolder treated with cardioversion in our ED or referred for scheduling of cardioversion. Clinical outcome measures were conversion to sinus rhythm, immediate adverse effects (hypotension, arrythmia, or bronchial aspiration), revisiting within 90 days for atrial fibrillation, and complications (stroke, major bleeding, heart failure, or death). We studied factors associated with recurrence and adverse effects according to sex. RESULTS: Cardioversion was used in 365 episodes (median patient age, 67 years); 38.6% were women. Cardioversion was applied in the ED in 75.1% of the episodes, and 24.9% were referred for scheduled cardioversion. Sinus rhythm was restored in 90.7% of the episodes. Emergency cardioversion was more effective than a scheduled procedure (odds ratio [OR], 4.258; 95% CI, 2.046-8.859; P < .001). No serious immediate adverse effects were reported, but 16.7% of the patients revisited for atrial fibrillation within 90 days. Factors associated with revisits were heart failure (hazard ratio [HR], 2.603; 95% CI, 1.298-5.222; P = .007), sleep apnea (HR, 2.598; 95% CI, 1.163-5.803; P = .020), and, in women, hypertension (HR, 3.706; 95% CI, 1.051-13.068; P = .042). Eleven patients developed late adverse events, including stroke (n = 2), major bleeding (n = 1), heart failure (n = 5), and death (n = 3). CONCLUSIONS: Cardioversion is a useful, effective, and safe treatment for atrial fibrillation in the ED, although there are frequent recurrences. Factors associated with recurrence differ according to sex.

OBJETIVO: Conocer la seguridad y eficacia de la cardioversión eléctrica (CVE) en la fibrilación auricular (FA) en un servicio de urgencias hospitalario (SUH). METODO: Estudio observacional y retrospectivo realizado en un SUH. Se revisaron los episodios de FA en pacientes con edad igual o mayor a 18 años a los que se les realizó CVE en el SUH o se les programó de forma diferida. Las variables resultado fueron: reversión a ritmo sinusal (RS), efectos adversos inmediatos (hipotensión, arritmia y broncoaspiración), reconsulta a 90 días por FA y desarrollo de complicaciones (ictus, hemorragia mayor, insuficiencia cardiaca y mortalidad). Se estudiaron los factores asociados a recurrencia y efectos adversos, y se analizaron las diferencias por sexo. RESULTADOS: Se incluyeron 365 episodios de CVE (67 años; 38,6% mujeres); el 75,1% se realizó en el SUH y el 24,9% se derivaron para CVE diferida. El 90,7% revirtieron a RS. La CVE urgente fue más efectiva que la diferida (OR 4,258; IC 95% 2,046-8,859; p < 0,001). No hubo efectos adversos inmediatos graves. El 16,7% de pacientes reconsultaron por FA en los 90 días posteriores. Los factores asociados a reconsulta fueron insuficiencia cardiaca (HR 2,603; IC 95% 1,298-5,222; p = 0,007), apnea del sueño (HR 2,598; IC 95% 1,163-5,803; p = 0,020) y, en mujeres, hipertensión arterial (HR 3,706;IC 95% 1,051-13,068; p = 0,042). Tras la CVE, 11 pacientes presentaron eventos adversos tardíos que incluyeron ictus (n = 2), hemorragia mayor (n = 1), insuficiencia cardiaca (n = 5) y muerte (n = 3). CONCLUSIONES: La CVE es útil, eficaz y segura para la FA en los SUH, aunque las recurrencias son frecuentes. Los factores asociados a recurrencia difieren entre sexos.

Incidentally Induced Atrial Fibrillation During Programmed Electrical Stimulation in Patients With Depressed Left Ventricular Systolic Function After an Acute Myocardial Infarction.

BACKGROUND: The aim of this study was to investigate the clinical implication of incidentally induced atrial fibrillation (AF) during programmed electrical stimulation (PES) in patients with left ventricular systolic dysfunction (≤40%) after an acute myocardial infarction (MI). METHODS: In this study, we included 231 patients from the Cardiac Arrhythmias and RIsk Stratification after Myocardial InfArction (CARISMA) study with left ventricular ejection fraction ≤40% and no prior history of AF. These patients underwent PES 6 weeks post-MI as part of the study protocol. Patients all received an implantable cardiac monitor (ICM) 3-21 days post-MI and were continuously monitored for cardiac arrhythmias for 2 years. Induction of AF was unwanted but reported if this incidentally occurred. RESULTS: A total of 61 patients (26%) developed AF within 2 years of follow-up, in which n = 10 (29%) had incidental AF during PES at baseline. The overall risk of AF was not significantly increased in patients with incidental AF (n = 34) during PES compared to patients without incidental AF (n = 197) (HR 1.6 [0.9-3.0], p = 0.14). The risk of bradyarrhythmia (HR = 0.2 [0.0-1.2], p = 0.07), ventricular arrhythmias (HR = 0.7 [0.1-5.8], p = 0.77), and major cardiovascular events (MACE) (HR 0.5 [0.2-1.7], p = 0.28) was not significantly different in patients with versus without incidental AF. CONCLUSIONS: Incidentally induced AF during PES in post-MI patients with reduced LVEF was not significantly associated with a higher risk of long-term atrial fibrillation, other cardiac arrhythmias, or major cardiac events. TRIAL REGISTRATION: NCT00145119.

Prevalence and Associated Factors of Paroxysmal Atrial Fibrillation and Atrial Arrhythmias During Hospitalizations for Exacerbation of COPD.

Purpose: This study aimed to investigate the proportion and risk factors of paroxysmal atrial fibrillation (AF) and atrial arrhythmias (AA) in patients hospitalized for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Vietnam. Patients and Methods: A prospective observational study was conducted at two major hospitals in Hanoi, Vietnam, from January 2022 to January 2023. A total of 197 AECOPD patients were recruited. ECG and 24-hour Holter ECG were used to diagnose paroxysmal AF and AA. Results: The prevalence of paroxysmal AF and AA were 15.2% and 72.6%, respectively. Factors associated with a higher likelihood of paroxysmal AF included aging 75 years old and above (aOR = 3.15; 95% CI: 1.28 to 8.48), Premature atrial complex (PAC) with 500 or more (aOR = 3.81; 95% CI: 1.48 to 10.97) and severity of COPD as group C and D (aOR = 3.41; 95% CI: 1.28 to 10.50). For AA, aging 75 years old and above (aOR = 2.25; 95% CI: 1.28 to 5.20), smoking (aOR = 2.10; 95% CI: 1.07 to 4.23) and P wave dispersion (PWD) with 40 milliseconds or more (aOR = 3.04; 95% CI: 1.54 to 6.19) were associated with a higher likelihood of AA. Conclusion: Overall, our findings highlight the associated factors with the paroxysmal AF and AA among AECOPD patients. This underscores the importance of a multifaceted approach to risk assessment and management in this vulnerable population, focusing not only on respiratory symptoms but also on comprehensive cardiovascular evaluation and intervention.

Actioning atrial fibrillation identified by ambulance services in England: a qualitative exploration.

OBJECTIVES: To explore the acceptability and feasibility of detection of atrial fibrillation (AF) by emergency medical services (EMS) and identify potential barriers and facilitators to implementing a formal pathway to facilitate follow-up in primary care, which could reduce the risk of AF-related stroke. DESIGN: Qualitative study using focus groups and one-to-one interviews guided by a semistructured topic guide. SETTING: North East England. PARTICIPANTS: Focus groups with 18 members of the public and one-to-one online interviews with 11 healthcare and service providers (six paramedics and five experts representing cardiology, general practice (GP), public health, research, policy and commissioning). RESULTS: All participant groups were supportive of a role of EMS in identifying AF as part of routine assessment and formalising the response to AF detection. However, this should not create delays for EMS since rate-controlled AF is non-urgent and alternative community mechanisms exist to manage it. Public participants were concerned about communication of the AF diagnosis and whether this should be 'on scene' or in a subsequent GP appointment. Paramedics reported frequent incidental identification of AF, but it is not always clear 'on scene' that this is a new diagnosis, and there is variation in practice regarding whether (and how) this is communicated to the GP. Paramedics also focused on ensuring the safety of non-conveyed patients and a perceived need for an 'active' reporting process, so that a finding of AF was actioned. Field experts felt that a formal pathway would be useful and favoured a simple intervention without adding to time pressures unnecessarily. CONCLUSIONS: There is support for the development of a formal pathway to ensure follow-up for people with AF that is incidentally detected by EMS. This has the potential to improve anticoagulation rates and reduce the risk of stroke.

Key needs, quality performance indicators and outcomes for patients with atrial fibrillation and multimorbidity: The AFFIRMO study.

BACKGROUND: Patients with atrial fibrillation (AF) often have concomitant long-term conditions that negatively impact their quality of life and the clinical management they receive. The AFFIRMO study aimed to identify the needs, quality performance indicators (QPIs), and outcomes relevant to patients, caregivers and healthcare professionals (HCPs) to improve the care of patients with AF. METHODS: An on-line survey to collect the key needs, QPIs, and outcomes relevant to patients with AF, their caregivers and HCPs, was distributed between May 2022 and January 2023 in five countries (UK, Italy, Denmark, Romania and Spain). Results from the on-line survey were discussed in a three-round Delphi process with international representatives of patients with AF, caregivers, and HCPs to determine the key needs, QPIs and outcomes for the management of patients with AF and multimorbidity. RESULTS: 659 patients (47.2% males, mean (SD) age 70.9 (10.2) years), 201 caregivers (26.9% males, mean (SD) age: 58.3 (SD 15.2) years), and 445 HCPs (57.8% males, mean (SD) age 47.4 (10.6) years) participated in the survey. An initial list of 27 needs, 9 QPIs, and 17 outcomes were identified. Eight patients, two caregivers, and 11 HCPs participated in the Delphi process. Nineteen (70%) needs, 8 (89%) QPIs, and 13 (76%) outcomes reached "consensus in", and were included in the final list. CONCLUSIONS: The final key needs, QPIs and outcomes obtained from the Delphi process will inform the AFFIRMO clinical trial, which aims to test the iABC app which incorporates an empowerment toolbox for patients and their caregivers, providing information to improve patient engagement and empowerment to help improve the clinical and self-management of patients with AF in the context of multimorbidity.

Safety of different therapies for atrial fibrillation: a network meta-analysis.

OBJECTIVE: Most published studies have aimed to compare the effectiveness of different treatment strategies for atrial fibrillation (AF), while few articles have comprehensively compared the safety of therapeutic measures.The aim of the article was to assess the safety of different therapeutic measures (different ablation techniques, antiarrhythmic drugs and surgery) in patients with AF. METHOD: A comprehensive and systematic search was undertaken across various databases, namely PubMed, Embase, Cochrane Library, and Web of Science, with the aim of identifying pertinent randomized controlled trials (RCTs) that delve into the safety aspects of diverse atrial fibrillation treatment strategies. The search was conducted up until December 1st, 2023. R4.2.3 software gemtc package was used for data analysis, Review Manager 5.3 was used for quality assessment of included studies, and stata15.0 was used for publication bias.Safety is defined as the adverse outcomes that occur in different treatment strategies for atrial fibrillation, with specific adverse events as described below. RESULT: 22 RCTs (involving 5073 subjects) with interventions including cryoballoon ablation (CA), radiofrequency ablation (RF), laser balloon ablation (LB), pulmonary vein ablation catheter (PVAC), antiarrhythmic drugs (AADS), and surgery (SA) were included in this study. In this article, medication and surgery were combined into the same intervention (non-traditional treatment measure, UT). UT was not associated with pericardial effusion (OR:4.27e-10, 95%CI:4.91e-30-0.0663), infections (OR:0.248, 95%CI:0.0584-0.89), arrhythmias (OR:0.609,95%CI:0.393-0.936), pseudoaneurysms (OR:5.57e-10, 95%CI:1.16e-31-0.934) and pulmonary vein stenosis (OR:1.16e-09, 95%CI:6.56e-24-0.194). Complications of the procedure were mainly mechanical injuries. Among the various ablation strategies, radiofrequency ablation had a lower incidence of phrenic nerve palsy and pain (OR:4.01e-06, 95%CI:1.18e-17-0.710) than cryoballoon ablation, which was superior to radiofrequency ablation in terms of infection rates. Finally, there were no significant differences between the various ablation techniques in terms of other complication rates. CONCLUSION: Because the interventions in the UT group were predominantly AADS and antiarrhythmic drug therapy didn't have some of the common aggressive complications of ablation strategies, the UT group had a low rate of complications such as pericardial effusion, postprocedural arrhythmia, pseudoaneurysm, and pulmonary vein stenosis compared with various catheter ablation strategies. Additionally, we also discovered between the various ablation technology groups, there was no significant difference in the incidence of major adverse events.

Differentiating Left Atrial Pressure Responses in Paroxysmal and Persistent Atrial Fibrillation: Implications for Diagnosing Heart Failure With Preserved Ejection Fraction and Managing Atrial Fibrillation.

BACKGROUND: Increased left atrial pressure (LAP) contributes to dyspnea and heart failure with preserved ejection fraction in patients with atrial fibrillation (AF). The purpose of this study was to investigate the differences in baseline LAP and LAP response to rapid pacing between paroxysmal and persistent AF. METHODS AND RESULTS: This observational study prospectively enrolled 1369 participants who underwent AF catheter ablation, excluding those with reduced left ventricular ejection fraction. H2FPEF score was calculated by echocardiography and baseline characteristics. Patients underwent LAP measurements during AF, sinus rhythm, and heart rates of 90, 100, 110, and 120 beats per minute (bpm), induced by right atrial pacing and isoproterenol. The baseline LAP-peak in the persistent AF group consistently exceeded that in the paroxysmal AF (PAF) group across each H2FPEF score subgroup (all P<0.05). LAP-peak increased with pacing (19.5 to 22.5 mm Hg) but decreased with isoproterenol (20.4 to 18.4 mm Hg). Under pacing, patients with PAF exhibited a significantly lower LAP-peak (90 bpm) than those with persistent AF (17.7±8.2 versus 21.1±9.3 mm Hg, P<0.001). However, there was no difference in LAP-peak (120 bpm) between the 2 groups (22.1±8.1 versus 22.9±8.4 mm Hg, P=0.056) because the LAP-peak significantly increased with heart rate in the group with PAF. CONCLUSIONS: Patients with PAF exhibited lower baseline LAP with greater increases during rapid pacing compared with individuals with persistent AF, indicating a need to revise the H2FPEF score for distinguishing PAF from persistent AF and emphasizing the importance of rate and rhythm control in PAF for symptom control.

Position Statement on Cardiac Computed Tomography Following Left Atrial Appendage Occlusion.

Left atrial appendage occlusion (LAAO) is rapidly growing as valid stroke prevention therapy in atrial fibrillation. Cardiac imaging plays an instrumental role in preprocedural planning, procedural execution, and postprocedural follow-up. Recently, cardiac computed tomography (CCT) has made significant advancements, resulting in increasing use both preprocedurally and in outpatient follow-up. It provides a noninvasive, high-resolution alternative to the current standard, transesophageal echocardiography, and may display advantages in both the detection and characterization of device-specific complications, such as peridevice leak and device-related thrombosis. The implementation of CCT in the follow-up after LAAO has identified new findings such as hypoattenuated thickening on the atrial device surface and left atrial appendage contrast patency, which are not readily assessable on transesophageal echocardiography. Currently, there is a lack of standardization for acquisition and interpretation of images and consensus on definitions of essential findings on CCT in the postprocedural phase. This paper intends to provide a practical and standardized approach to both acquisition and interpretation of CCT after LAAO based on a comprehensive review of the literature and expert consensus among European and North American interventional and imaging specialists.
