Small Airway Disease in Pre-Chronic Obstructive Pulmonary Disease with Emphysema: A Cross-Sectional Study.

Rationale: Small airway disease is an important pathophysiological feature of chronic obstructive pulmonary disease (COPD). Recently, "pre-COPD" has been put forward as a potential precursor stage of COPD that is defined by abnormal spirometry findings or significant emphysema on computed tomography (CT) in the absence of airflow obstruction. Objective: To determine the degree and nature of (small) airway disease in pre-COPD using microCT in a cohort of explant lobes/lungs. Methods: We collected whole lungs/lung lobes from patients with emphysematous pre-COPD (n = 10); Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage I (n = 6), II (n = 6), and III/IV (n = 7) COPD; and controls (n = 10), which were analyzed using CT and microCT. The degree of emphysema and the number and morphology of small airways were compared between groups, and further correlations were investigated with physiologic measures. Airway and parenchymal pathology was also validated with histopathology. Measurements and Main Results: The numbers of transitional bronchioles and terminal bronchioles per milliliter of lung were significantly lower in pre-COPD and GOLD stages I, II, and III/IV COPD compared with controls. In addition, the number of alveolar attachments of the transitional bronchioles and terminal bronchioles was also lower in pre-COPD and all COPD groups compared with controls. We did not find any differences between the pre-COPD and COPD groups in CT or microCT measures. The percentage of emphysema on CT showed the strongest correlation with the number of small airways in the COPD groups. Histopathology showed an increase in the mean chord length and a decrease in alveolar surface density in pre-COPD and all GOLD COPD stages compared with controls. Conclusions: Lungs of patients with emphysematous pre-COPD already show fewer small airways and airway remodeling even in the absence of physiologic airway obstruction.

The impact of diabetes on mortality rates after lower extremity amputation.

OBJECTIVE: To assess the impact of diabetes, amputation level, sex and age on mortality rates after lower extremity amputation (LEA) in Belgium, and to assess temporal trends in one-year survival rates from 2009 to 2018. METHODS: Nationwide data on individuals who underwent minor and major LEA from 2009 to 2018 were collected. Kaplan-Meier survival curves were constructed. A Cox regression model with time-varying coefficients was used to estimate the likelihood of mortality after LEA in individuals with or without diabetes. Matched amputation-free individuals with or without diabetes were used for comparison. Time trends were analysed. RESULTS: Amputations 41,304 were performed: 13,247 major and 28,057 minor. Five-year mortality rates in individuals with diabetes were 52% and 69% after minor and major LEA, respectively (individuals without diabetes: 45% and 63%, respectively). In the first six postoperative months, no differences in mortality rates were found between individuals with or without diabetes. Later, hazard ratios (HRs) for mortality in individuals with diabetes (compared with no diabetes) after minor LEA ranged from 1.38 to 1.52, and after major LEA from 1.35 to 1.46 (all p ≤ 0.005). Among individuals without LEA, HRs for mortality in diabetes (versus no diabetes) were systematically higher compared to the HRs for mortality in diabetes (versus no diabetes) after minor and major LEA. One-year survival rates did not change for individuals with diabetes. CONCLUSIONS: In the first six postoperative months, mortality rates after LEA were not different between individuals with or without diabetes; later, diabetes was significantly associated with increased mortality. However, as HRs for mortality were higher in amputation-free individuals, diabetes impacts mortality less in the minor and major amputation groups relative to the comparison group of individuals without LEA.

The diagnosis and management of chronic lung allograft dysfunction.

PURPOSE OF REVIEW: Chronic lung allograft dysfunction (CLAD) remains a life-threatening complication following lung transplantation. Different CLAD phenotypes have recently been defined, based on the combination of pulmonary function testing and chest computed tomography (CT) scanning and spurred renewed interests in differential diagnosis, risk factors and management of CLAD. RECENT FINDINGS: Given their crucial importance in the differential diagnosis, we will discuss the latest development in assessing the pulmonary function and chest CT scan, but also their limitations in proper CLAD phenotyping, especially with regards to patients with baseline allograft dysfunction. Since no definitive treatment exists, it remains important to timely identify clinical risk factors, but also to assess the presence of specific patterns or biomarkers in tissue or in broncho alveolar lavage in relation to CLAD (phenotypes). We will provide a comprehensive overview of the latest advances in risk factors and biomarker research in CLAD. Lastly, we will also review novel preventive and curative treatment strategies for CLAD. SUMMARY: Although this knowledge has significantly advanced the field of lung transplantation, more research is warranted because CLAD remains a life-threatening complication for all lung transplant recipients.

A call for action to include psychosocial management into holistic, integrated care for patients with atrial fibrillation.

Contemporary management of atrial fibrillation (AF) has become increasingly complex. Therefore, strong efforts have been made during the past decade to develop models for structured, integrated care for patients with AF. These have also been incorporated in international guidelines for the management of patients with AF. However, implementation of integrated care approaches in daily clinical practice is scarce and far from optimal, and it may require a re-thinking of the structure of the healthcare system. The reasons for the poor implementation are many, from limited time and economic resources to deficits in postgraduate education of healthcare professionals, lack of involvement of patients in how integrated care should be designed, and fragmentation of the healthcare system. Moreover, patients' psychological challenges, which not only impact patients' adherence to treatment but, if untreated, increase their risk of morbidity, mortality, and poor quality of life, are not given sufficient attention. It is time to start a necessary discussion of what integrated care should be, what it should contain, and what is necessary to implement it in daily clinical practice.

Measurement properties of utility-based health-related quality of life measures in cardiac rehabilitation and secondary prevention programs: a systematic review.

PURPOSE: To identify utility-based patient-reported outcome measures (PROMs) for assessing health-related quality of life (HRQoL) in cardiac rehabilitation and secondary prevention programs (CR) and appraise existing evidence on their measurement properties. Secondly, to link their items to the International Classification of Functioning Disability and Health (ICF) and the International Consortium of Health Outcome Measures (ICHOM) domains for cardiovascular disease (CVD). METHODS: Eight databases were searched. The review followed the COSMIN and JBI guidelines for measurement properties systematic reviews and PRISMA 2020 reporting guidelines. Non-experimental and observational empirical studies of patients ≥ 18 years of age with CVD undergoing CR and assessed quality of life (QoL) or HRQoL using utility-based PROMs or one accompanied by health state utilities were included. RESULTS: Nine PROMs were identified with evidence on measurement properties for three measures: the German translations of SF-12, EQ-5D-5L, and MacNew heart disease HRQoL questionnaire. There was moderate quality evidence for responsiveness and hypothesis testing of the SF-12 and EQ-5D-5L, and high-quality evidence for responsiveness and hypothesis testing for the MacNew. All items of SF-12 and EQ-5D were linked to ICF categories, but four items of the MacNew were not classified or defined. All the PROM domains were mapped onto similar constructs from the ICHOM global sets. CONCLUSION: Three utility-based PROMs validated in CR were identified: the German versions of the EQ-5D and SF-12 and the MacNew questionnaire. These PROMs are linked to a breadth of ICF categories and all ICHOM global sets. Additional validation studies of PROMs in CR are required.

Implementation of a screening and management pathway for chronic obstructive pulmonary disease in patients with atrial fibrillation.

AIMS: Chronic obstructive pulmonary disease (COPD) negatively impacts the efficacy of heart rhythm control treatments in patients with atrial fibrillation (AF). Although COPD is recognized as a risk factor for AF, practical guidance about how and when to screen for COPD is not available. Herein, we describe the implementation of an integrated screening and management pathway for COPD into the existing pre-ablation work-up in an AF outpatient clinic infrastructure. METHODS AND RESULTS: Consecutive unselected patients accepted for AF catheter ablation in the Maastricht University Medical Center+ were prospectively screened for airflow limitation using handheld (micro)spirometry at the pre-ablation outpatient clinic supervised by an AF nurse. Patients with results suggestive of airflow limitation were offered referral to the pulmonologist. Handheld (micro)spirometry was performed in 232 AF patients, which provided interpretable results in 206 (88.8%) patients. Airflow limitation was observed in 47 patients (20.3%). Out of these 47 patients, 29 (62%) opted for referral to the pulmonologist. The primary reason for non-referral was low perceived symptom burden. Using this screening strategy 17 (out of 232; 7.3%) ultimately received a diagnosis of chronic respiratory disease, either COPD or asthma. CONCLUSION: A COPD care pathway can successfully be embedded in an existing AF outpatient clinic infrastructure, using (micro)spirometry and remote analysis of results. Although one out of five patients had results suggestive of an underlying chronic respiratory disease, only 62% of these patients opted for a referral. Pre-selection of patients as well as patient education might increase the diagnostic yield and requires further research.

Psychometric Validation of the Chinese Version of the Atrial Fibrillation Knowledge Scale in Chinese Patients With Atrial Fibrillation.

BACKGROUND: Assessment of patients' knowledge on atrial fibrillation (AF) and its management is important for evaluating their learning needs. However, a validated and comprehensive instrument to be used among Chinese patients is yet to be developed. OBJECTIVES: The aim of this study was to develop and validate the Chinese version of the Atrial Fibrillation Knowledge Scale (AFKS-C) in Chinese patients. METHODS: The 11-item AFKS was translated, and then content and face validations were conducted by an expert panel and patients with AF. A sample of 255 patients with AF was recruited from a university-affiliated hospital to evaluate its psychometric properties. The internal consistency and test-retest reliability were evaluated using the Kuder-Richardson formula 20 and κ statistics. Item analysis determined the item difficulty index and item discrimination coefficients. Factorial and discriminant validity were evaluated using exploratory factor analysis and the known-groups method. RESULTS: The content validity index of the AFKS-C was 0.94, and the Kuder-Richardson formula 20 value was 0.60. The difficulty indices of the items ranged from 0.36 to 0.89, and the point-biserial coefficients of the items ranged from 0.122 to 0.255, indicating sufficient discriminatory ability. The test-retest reliability was acceptable, because the κ values ranged from 0.234 to 0.710. The principal axis factoring analysis indicated a 3-factor structure that explained 50.4% of the total variance. The AFKS-C also demonstrated satisfactory discriminant validity, having yielded significantly different scores between patients with newly diagnosed and established AF. CONCLUSION: The AFKS-C has acceptable psychometric properties and can be used to measure the knowledge of patients and evaluate the effects of patient education programs.

The information needs of patients with atrial fibrillation: A scoping review.

AIMS AND OBJECTIVES: To identify the atrial fibrillation (AF)-specific information needs of patients with AF. BACKGROUND: Patients' understanding of AF is pertinent to optimising treatment and outcomes, thus highlighting the need for effective patient education. The information required to deliver effective AF-specific patient education is less examined. METHODS: Guided by Arksey and O'Malley's framework, a scoping review was conducted for studies reporting the AF-specific information needs of patients with AF. Systematic searches were conducted across six databases (Medline, PubMed, CINAHL, Scopus, PsycINFO and ProQuest). All analyses were narrated in prose and outlined in tables. The PRISMA-ScR checklist was used to report this review. RESULTS: The systematic search yielded 3816 articles, of which 22 were included. Three major themes emerged from the thematic analysis. Each theme was supported by three subthemes. First, in 'Understanding AF', patients reported the need for 'Easy-to-understand information', information on the 'Screening and diagnosis' of AF and 'Trajectory of disease and its associated risks'. Second, in 'Treating AF', patients required information on the 'Role of anticoagulation', 'Existing or novel therapeutic options' and 'Monitoring effectiveness of treatment'. Lastly, in 'Living with AF', patients needed education in 'Symptom management', 'Secondary prevention of risks' and 'Recognition of emergency situations'. CONCLUSIONS: This review has identified the key AF-specific information needs of patients with AF. Being cognisant of the information needs of patients with AF, healthcare providers may become more effective in developing person-centred patient education interventions. RELEVANCE TO CLINICAL PRACTICE: Delivering relevant patient education is an important cornerstone for atrial fibrillation care. Nurses by convention play a professional role in patient education. It may be facilitative for nurses to refer to the review findings when developing and implementing patient education interventions. Being in the midst of an ongoing pandemic, patient education strategies may require the use of telecommunication technologies.

An Overview of the Use of Anti-Angiogenic Agents in the Treatment of Thymic Epithelial Tumors.

Angiogenesis significantly influences the carcinogenesis of thymic epithelial tumors (TET). Both thymomas and thymic carcinoma (TC) overexpress VEGF-A and VEGFR-1 and -2. This review aims to provide an appraisal of the use of anti-angiogenics in the treatment of TET. The literature research identified 16 studies that were deemed eligible for further analysis. Seven studies assessed the clinical efficacy of sunitinib and five studies the use of apatinib and/or anlotinib. The multicenter Japanese phase II REMORA trial investigated the efficacy of lenvatinib, which is a multi-targeted inhibitor of VEGFR, FGFR, RET, c-Kit, and other kinases. The objective response rate was 38% (25.6-52%), which is the highest documented in TET that progressed after first-line chemotherapy. Anti-angiogenic agents may be useful in the treatment of TET, which are not amenable to curative treatment. Their toxicity profile seems to be acceptable. However, angiogenesis inhibitors do not appear to have a major influence on either thymomas or TC, although multikinase inhibitors may have some effect on TC. The current evidence suggests that the most active agent is lenvatinib, whereas sunitinib could be proposed as an acceptable second-line therapy for TC. Further research concerning the combination of immune checkpoint inhibitors with anti-angiogenic drugs is warranted.

A Clinical Guide for Assessment and Prescription of Exercise and Physical Activity in Cardiac Rehabilitation. A CSANZ Position Statement.

Patients with cardiovascular disease benefit from cardiac rehabilitation, which includes structured exercise and physical activity as core components. This position statement provides pragmatic, evidence-based guidance for the assessment and prescription of exercise and physical activity for cardiac rehabilitation clinicians, recognising the latest international guidelines, scientific evidence and the increasing use of technology and virtual delivery methods. The patient-centred assessment and prescription of aerobic exercise, resistance exercise and physical activity have been addressed, including progression and safety considerations.

Cardiovascular Nursing and Climate Change: A Call to Action From the CSANZ Cardiovascular Nursing Council.

This Call to Action aims to provide key considerations for cardiovascular nursing, related to climate and environmental impacts. Strategies to optimise nursing preparation, immediate response and adaptation to climate emergencies are crucial to ensure those at greatest risk, including First Nations peoples, are protected from potentially avoidable harm. Professionals who manage climate consequences must also understand the impact of their care on the root cause of the problem.

Assessment of the general public's knowledge of atrial fibrillation through social media: a cross-sectional study.

BACKGROUND: Early detection and timely treatment of atrial fibrillation (AF) remains pivotal to preventing AF-related complications. Public involvement in recognising potential AF symptoms and managing AF is vital for early detection and treatment of AF. OBJECTIVE: The aim of the study is to assess the general public's knowledge of AF using an online survey, disseminated via social media. METHODS: A cross-sectional online survey of the general public was conducted between November to December 2021. The survey's URL was shared on National University Heart Centre, Singapore's official Facebook page. Digital marketing strategies were employed to recruit members of the public. The 27-item survey assessed public's knowledge across five domains: basic information about AF, risk factors of AF, detection of AF, prevention of AF, and management of AF. RESULTS: The survey involved 620 participants. Approximately two-thirds were between the ages 21 to 40 years (64.5%), female (60%) and had at least a degree (64.7%) as their highest level of education. Participants obtained a mean percentage score of 63.3 ± 26.0 for their AF knowledge. One-way ANOVA was done to examine the associations between the participants' characteristics and their knowledge of AF. There were no statistically significant differences in the AF knowledge scores across the various sociodemographic subgroups. CONCLUSIONS: Members of the public recruited from Facebook and via digital marketing had moderately good knowledge of AF. However, public awareness pertaining to preventing AF has potential for improvement. The utility of social media in reaching the general public was illustrated through this study.

Alcohol intake and bradyarrhythmia risk: a cohort study of 407 948 individuals.

AIMS: There is a paucity of epidemiological evidence on alcohol and the risk of bradyarrhythmias. We thus characterized associations of total and beverage-specific alcohol consumption with incident bradyarrhythmias using data from the UK Biobank. METHODS AND RESULTS: Alcohol consumption reported at baseline was calculated as UK standard drinks (8 g alcohol)/week. Bradyarrhythmia events were defined as sinus node dysfunction (SND), high-level atrioventricular block (AVB), and permanent pacemaker implantations. Outcomes were assessed through hospitalization and death records, and dose-response associations were characterized using Cox regression models with correction for regression dilution bias. We studied 407 948 middle-aged individuals (52.4% female). Over a median follow-up time of 11.5 years, a total of 8 344 incident bradyarrhythmia events occurred. Increasing total alcohol consumption was not associated with an increased risk of bradyarrhythmias. Beer and cider intake were associated with increased bradyarrhythmia risk up to 12 drinks/week; however, no significant associations were observed with red wine, white wine, or spirit intake. When bradyarrhythmia outcomes were analysed separately, a negative curvilinear was observed for total alcohol consumption and risk of SND, but no clear association with AVB was observed. CONCLUSION: In this predominantly White British cohort, increasing total alcohol consumption was not associated with an increased risk of bradyarrhythmias. Associations appeared to vary according to the type of alcoholic beverage and between different types of bradyarrhythmias. Further epidemiological and experimental studies are required to clarify these findings.

A VIRTUAL Sleep Apnoea management pathway For the work-up of Atrial fibrillation patients in a digital Remote Infrastructure: VIRTUAL-SAFARI.

AIMS: In atrial fibrillation (AF) patients, untreated sleep-disordered breathing (SDB) is associated with lower success rates of rhythm control strategies and as such structured SDB testing is recommended. Herein, we describe the implementation of a virtual SDB management pathway in an AF outpatient clinic and examine the utility and feasibility of this new approach. METHODS AND RESULTS: Prospectively, consecutive AF patients accepted for AF catheter ablation procedures without previous diagnosis of SDB were digitally referred to a virtual SDB management pathway and instructed to use WatchPAT-ONE (ITAMAR) for one night. Results were automatically transferred to a virtual sleep laboratory, upon which a teleconsultation with a sleep physician was planned. Patient experience was measured using surveys. SDB testing was performed in 119 consecutive patients scheduled for AF catheter ablation procedures. The median time from digital referral to finalization of the sleep study report was 18 [11-24] days. In total, 65 patients (55%) were diagnosed with moderate-to-severe SDB. Patients with SDB were prescribed more cardiovascular drugs and had higher body mass indices (BMI, 29 ± 3.3 vs. 27 ± 4.4kg/m2, P < 0.01). Patients agreed that WatchPAT-ONE was easy to use (91%) and recommended future use of this virtual pathway in AF outpatient clinics (86%). Based on this remote SDB testing, SDB treatment was recommended in the majority of patients. CONCLUSION: This novel virtual AF management pathway allowed remote SDB testing in AF outpatient clinics with a short time to diagnosis and high patient satisfaction. Structured SDB testing results in a high detection of previously unknown SDB in AF patients scheduled for AF ablation.

Chronic obstructive pulmonary disease and atrial fibrillation: an interdisciplinary perspective.

Chronic obstructive pulmonary disease (COPD) is highly prevalent among patients with atrial fibrillation (AF), shares common risk factors, and adds to the overall morbidity and mortality in this population. Additionally, it may promote AF and impair treatment efficacy. The prevalence of COPD in AF patients is high and is estimated to be ∼25%. Diagnosis and treatment of COPD in AF patients requires a close interdisciplinary collaboration between the electrophysiologist/cardiologist and pulmonologist. Differential diagnosis may be challenging, especially in elderly and smoking patients complaining of unspecific symptoms such as dyspnoea and fatigue. Routine evaluation of lung function and determination of natriuretic peptides and echocardiography may be reasonable to detect COPD and heart failure as contributing causes of dyspnoea. Acute exacerbation of COPD transiently increases AF risk due to hypoxia-mediated mechanisms, inflammation, increased use of beta-2 agonists, and autonomic changes. Observational data suggest that COPD promotes AF progression, increases AF recurrence after cardioversion, and reduces the efficacy of catheter-based antiarrhythmic therapy. However, it remains unclear whether treatment of COPD improves AF outcomes and which metric should be used to determine COPD severity and guide treatment in AF patients. Data from non-randomized studies suggest that COPD is associated with increased AF recurrence after electrical cardioversion and catheter ablation. Future prospective cohort studies in AF patients are needed to confirm the relationship between COPD and AF, the benefits of treatment of either COPD or AF in this population, and to clarify the need and cost-effectiveness of routine COPD screening.

Evaluation of Temporal Artery Duplex Ultrasound for Diagnosis of Temporal Arteritis.

BACKGROUND: Temporal arteritis or giant cell arteritis is a form of systemic inflammatory vasculitis closely associated with polymyalgia rheumatica. It may have serious systemic, neurologic, and ophthalmic consequences as it may lead to impaired vision and blindness. Definitive diagnosis is made after histopathologic analysis of a superficial temporal artery (TA) biopsy, which requires a small surgical procedure often under local anesthesia. We investigated whether a noninvasive technique such as duplex ultrasound of the TA could replace histopathological analysis. METHODS: Eighty-one patients referred to our department for TA biopsy were first screened with a duplex ultrasound for a surrounding halo and/or occlusion of the TA. Presence of visual disturbances and unilateral pain (headache and/or tongue/jaw claudication) was noted before TA biopsy. Pathological analysis was considered the gold standard. Correlation between duplex findings, symptoms, and pathology was determined by Spearman's Rho test. The predictive value of a halo and TA occlusion on duplex were determined by ROC curve analysis. RESULTS: A halo or TA occlusion was found in 16.0% and 3.7% of patients, respectively. Unilateral pain was reported in 96% of cases while 82% complained of visual disturbances. Correlation coefficients for halo and occlusion were 0.471 and 0.404, respectively (P < 0.0001), suggesting a moderate correlation between duplex and biopsy. There was no significant correlation between visual impairment or pain and histologic findings. The ROC curve analysis showed a sensitivity of 53.3% and 20.0%, and specificity of 91.9% and 100% for presence of a halo and occlusion of the TA on duplex, respectively. CONCLUSIONS: Arterial duplex is a moderately sensitive but highly specific test for exclusion of temporal arteritis. We observed a moderate correlation between these findings on duplex and histopathological analysis as a gold standard. Arterial duplex may serve as a valuable diagnostic addition to prevent unnecessary surgical procedures and can even substitute biopsy in patients where surgery is not an option.

Obstructive sleep apnoea testing and management in atrial fibrillation patients: a joint survey by the European Heart Rhythm Association (EHRA) and the Association of Cardiovascular Nurses and Allied Professions (ACNAP).

Obstructive sleep apnoea (OSA) is highly prevalent in atrial fibrillation (AF) patients and associated with reduced response to rhythm control strategies. However, there is no practical guidance on testing for OSA in AF patients and for OSA treatment implementation. We sought to evaluate current practices and identify challenges of OSA management in AF. A descriptive cross-sectional study was performed with a content-validated survey to evaluate OSA management in AF by healthcare practitioners. Survey review, editing, and dissemination occurred via the European Heart Rhythm Association and the Association of Cardiovascular Nursing and Allied Professions and direct contact with arrhythmia centres. In total, 186 responses were collected. OSA-related symptoms were ranked as the most important reason to test for OSA in AF patients. The majority (67.7%) indicated that cardiologists perform 'ad-hoc' referrals. Only 11.3% initiated systematic testing by home sleep test or respiratory polygraphy and in addition, 10.8% had a structured OSA assessment pathway in place at the cardiology department. Only 6.7% of the respondents indicated that they test >70% of their AF patients for OSA as a component of rhythm control therapy. Various barriers were reported: no established collaboration between cardiology and sleep clinic (35.6%); lack in skills and knowledge (23.6%); lack of financial (23.6%) and personnel-related resources (21.3%). Structured testing for OSA occurs in the minority of AF patients. Centres apply varying methods. There is an urgent need for increased awareness and standardized pathways to allow OSA testing and treatment integration in the management of AF.

Risk factor management and atrial fibrillation.

The management of atrial fibrillation (AF) is multifaceted and treatment paradigms have changed significantly in the last century. The treatment of AF requires a comprehensive approach which goes beyond the treatment of the arrhythmia alone. Risk factor management has been introduced as a crucial pillar of AF management. As a result, the landscape of care delivery is changing as well, and novel models of comprehensive care delivery for AF have been introduced. This article reviews the evidence for the role of risk factor management in AF, how this can be integrated and implemented in clinical practice by applying novel models of care delivery, and finally identifies areas for ongoing research and potential healthcare reform to comprehensively manage the burgeoning AF population.

The interpretation of CHA2DS2-VASc score components in clinical practice: a joint survey by the European Heart Rhythm Association (EHRA) Scientific Initiatives Committee, the EHRA Young Electrophysiologists, the Association of Cardiovascular Nursing and Allied Professionals, and the European Society of Cardiology Council on Stroke.

This European Heart Rhythm Association (EHRA) Scientific Initiatives Committee, EHRA Young Electrophysiologists, Association of Cardiovascular Nursing and Allied Professionals, and European Society of Cardiology (ESC) Council on Stroke joint survey aimed to assess the interpretation of the CHA2DS2-VASc score components and preferred resources for calculating the score. Of 439 respondents, most were general cardiologists (46.7%) or electrophysiologists (EPs) (42.1%). The overall adherence to the ESC-defined scoring criteria was good. Most variation was observed in the interpretation of the significance of left ventricular ejection fraction and brain natriuretic peptide in the scoring for the 'C' component, as well as the 'one-off high reading of blood pressure' to score on the 'H' component. Greater confidence was expressed in scoring the 'H' component (72.3%) compared with the 'C' (46.2%) and 'V' (45.9%) components. Respondents mainly relied on their recall for the scoring of CHA2DS2-VASc score (64.2%). The three most favoured referencing resources varied among different professionals, with pharmacists and physicians relying mainly on memory or web/mobile app, whereas nurses favoured using a web/mobile app followed by memory or guidelines/protocol. In conclusion, this survey revealed overall good adherence to the correct definition of each component in scoring of the 'C', 'H', and 'V' elements of the CHA2DS2-VASc score, although the variation in their interpretations warrants further clarifications. The preferred referencing resources to calculate the score varied among different healthcare professionals. Guideline education to healthcare professionals and updated and unified online/mobile scoring tools are suggested to improve the accuracy in scoring the CHA2DS2-VASc score.

Implementation of an on-demand app-based heart rate and rhythm monitoring infrastructure for the management of atrial fibrillation through teleconsultation: TeleCheck-AF.

During the coronavirus 2019 (COVID-19) pandemic, outpatient visits in the atrial fibrillation (AF) clinic of the Maastricht University Medical Centre (MUMC+) were transferred into teleconsultations. The aim was to develop anon-demand app-based heart rate and rhythm monitoring infrastructure to allow appropriatmanagement of AF through teleconsultation. In line with the fundamental aspects of integrated care, including actively involving patients in the care process and providing comprehensive care by a multidisciplinary team, we implemented a mobile health (mHealth) intervention to support teleconsultations with AF patients: TeleCheck-AF. The TeleCheck-AF approach guarantees the continuity of comprehensive AF management and supports integrated care through teleconsultation during COVID-19. It incorporates three important components: (i) a structured teleconsultation ('Tele'), (ii) a CE-marked app-based on-demand heart rate and rhythm monitoring infrastructure ('Check'), and (iii) comprehensive AF management ('AF'). In this article, we describe the components and implementation of the TeleCheck-AF approach in an integrated and specialized AF-clinic through teleconsultation. The TeleCheck-AF approach is currently implemented in numerous European centres during COVID-19.
