Comparing Guidelines for Atrial Fibrillation: Focus on Emergency Medicine.

ostoperative atrial fibrillation (POAF) is a common adverse event following cardiac and noncardiac surgery and has been associated with late-onset atrial fibrillation (AF) and stroke. 1,2 Current guidelines do not provide recommendations on the optimal duration of oral anticoagulation (OAC) and screening strategies in POAF due to limited data. We sought to evaluate the real-world outpatient management of POAF.

Given the advances in atrial fibrillation (AF) management and the availability of new European Society of Cardiology (ESC) guidelines, there is a need for the systematic collection of contemporary data regarding the management and treatment of AF in ESC member countries. We conducted a registry of consecutive in- and outpatients with AF presenting to cardiologists in nine participating ESC countries. All patients with an ECG-documented diagnosis of AF confirmed in the year prior to enrolment were eligible. We enroled a total of 3119 patients from February 2012 to March 2013, with full data on clinical subtype available for 3049 patients (40.4% female; mean age 68.8 years). Common comorbidities were hypertension, coronary disease, and heart failure. Lone AF was present in only 3.9% (122 patients). Asymptomatic AF was common, particularly among those with permanent AF. Amiodarone was the most common antiarrhythmic agent used (∼20%), while beta-blockers and digoxin were the most used rate control drugs. Oral anticoagulants (OACs) were used in 80% overall, most often vitamin K antagonists (71.6%), with novel OACs being used in 8.4%. Other antithrombotics (mostly antiplatelet therapy, especially aspirin) were still used in one-third of the patients, and no antithrombotic treatment in only 4.8%. Oral anticoagulants were used in 56.4% of CHA2DS2-VASc = 0, with 26.3% having no antithrombotic therapy. A high HAS-BLED score was not used to exclude OAC use, but there was a trend towards more aspirin use in the presence of a high HAS-BLED score. The EURObservational Research Programme Atrial Fibrillation (EORP-AF) Pilot Registry has provided systematic collection of contemporary data regarding the management and treatment of AF by cardiologists in ESC member countries. Oral anticoagulant use has increased, but novel OAC use was still low. Compliance with the treatment guidelines for patients with the lowest and higher stroke risk scores remains suboptimal.

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.

In reply:

The treatment of atrial fibrillation (AF) remains one of the most difficult tasks in modern cardiology. In 2020, the European Society of Cardiology (ESC), together with the European Association for Cardio-Thoracic Surgery (EACTS), published guidelines for the diagnosis and management of AF, which include several new directives.ESC experts have formulated a novel concept for treatment of AF patients. The first component of treatment ‘A' (Anticoagulation/ Avoid stroke) is anticoagulant therapy in patients with increased risk of thromboembolic events. The second line of treatment ‘B' (Better symptom control) is the control of arrhythmia symptoms, selection of a rhythm control strategy or ventricular rate control. The third direction ‘C' includes cardiovascular risk factors and comorbid conditions management.The most challenging tasks in AF treatment are the control of arrhythmia symptoms. As in the previous version of 2016 guidelines, the latest ones identify 2 following strategies in treatment of AF: rhythm control and ventricular rate control.According to the current ESC/EACTS guidelines (2020), antiarrhythmic therapy continues to be one of the important directions in AF management. Early prescription f antiarrhythmic and anticoagulant agents with an increased risk of thromboembolic events, catheter ablation can not only improve the quality of life, but also the prognosis of patients with AF.

Tranexamic acid (TXA) is a common haemorrhage control agent in both emergency department (ED) settings and intra-operatively. While efficacy and potential harms are well-studied, there are no overviews of reviews completed on TXA efficacy in the ED setting. We set out to provide an overview of systematic reviews on TXA efficacy in trauma, gastrointestinal bleeding, and subarachnoid haemorrhage in the ED setting, with outcomes including short and long-term mortality, thromboembolic (TE) events, and whether bleeding continued. Our review is guided by the PRIOR statement. We searched Pubmed, Medline, and EMBASE using broad search terms for systematic reviews, and calculated pooled relative-risk ratios using random and fixed-effects modelling from these studies. A risk-of-bias assessment was also completed for each review. We identified 13 systematic reviews for inclusion, with a variety of different outcomes. We identified improvements in 24-h mortality for trauma (RR 0.88, 95% CI 0.84-0.92) and gastrointestinal bleeds (RR 0.30, 95% CI 0.23-0.39), and decreased long-term gastrointestinal bleed mortality (RR 0.57, 95% CI 0.48-0.69). We also identified an increase in TE risk in gastrointestinal bleeding scenarios (RR 1.45, 95% CI 1.09-1.94), but no other clinical scenarios. TXA is effective in reducing mortality following trauma and gastrointestinal bleeds, however, there is limited evidence at this time to support TXA administration in the context of subarachnoid haemorrhage. TE risk is elevated when used in gastrointestinal bleeds. Selective use in high-risk patients may be warranted. TXA should strongly be considered in management in ED and prehospital settings.

After the release of the 2010 guidelines of the European Society of Cardiology (ESC) and the 2011 update of the guidelines of the American Heart Association/American College of Cardiology (AHA/ACC), new evidence has emerged that requires adaption of current clinical practice in the treatment of atrial fibrillation (AF). In 2011, results were published from two central AF trials concerning prevention of stroke in patients with AF: the Rivaroxaban Once daily oral direct factor Xa inhibition Compared with vitamin K antagonist for prevention of stroke and Embolism Trial in Atrial Fibrillation (ROCKET-AF) and the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) study. Other important aspects that have emerged since 2010 include findings of stroke risk in paroxysmal AF patients, prediction for AF-associated stroke and haemorrhage, risk–benefit considerations concerning oral anticoagulation in patients with chronic kidney disease and risk–benefit considerations with use of antiplatelet agents, alone, combined, or in combination with oral anticoagulants in AF patients. Canadian AF guidelines were updated earlier this year, incorporating the new evidence. Also, in 2012, the American College of Chest Physicians released guidelines for the antithrombotic therapy of AF. Similar updates of the ESC and the AHA/ACC guidelines are expected, which will include new findings from the cardiovascular congresses over the upcoming months. Additionally, also in 2012, the Heart Rhythm Society, the European Heart Rhythm Association and the European Cardiac Arrhythmia Society (HRS/EHRA/ECAS) released a consensus statement on the interventional treatment of AF. The following short review summarises these new data and furthermore highlights our current clinical practice.

The Registry on Cardiac Rhythm Disorders Assessing the Control of Atrial Fibrillation (RecordAF) study is the first worldwide, prospective, survey of real-life management of atrial fibrillation (AF) in recently diagnosed patients (n = 5604) with a 1-year follow-up. Surveys of AF management have identified a divergence between guidelines and clinical practice, and an overinterpretation of guidelines in low-risk patients. : Physicians' theoretical approaches to rhythm and rate control were investigated using a pre-study questionnaire. One cardiologist, from each of the 583 sites in 6 regions, completed a questionnaire on their practice and management of AF patients. In AF patients with structural heart disease (SHD), amiodarone was the most frequent choice of first-line rhythm control agents in all regions. Amiodarone or sotalol tended to be the preferred second-line rhythm control agents, 1 exception being Central/South America. beta-Blockers were the first-line rate control agents for patients with AF and SHD in all regions, and calcium channel blockers and cardiac glycosides were the most common second-line rate control treatments in all regions, except Asia. In lone AF patients, propafenone (30.6%), flecainide (24.1%), and amiodarone (21.7%) were the most common global choices of first-line rhythm control, and amiodarone or sotalol were the preferred second-line rhythm control agents, 1 exception being Central/South America. These results highlight points of divergence from the American College of Cardiology (ACC)/ American Heart Association (AHA)/European Society of Cardiology (ESC) guidelines for the management of AF in terms of first-line drug selection in patients with associated SHD or coronary artery disease.

The myocardial-ischaemic-injury-index (MI3) is a novel machine learning algorithm for the early diagnosis of type 1 non-ST-segment elevation myocardial infarction (NSTEMI). The performance of MI3, both when using early serial blood draws (eg, at 1 h or 2 h) and in direct comparison with guideline-recommended algorithms, remains unknown. Our aim was to externally validate MI3 and compare its performance with that of the European Society of Cardiology (ESC) 0/1h-algorithm. In this secondary analysis of a multicentre international diagnostic cohort study, adult patients (age >18 years) presenting to the emergency department with symptoms suggestive of myocardial infarction were prospectively enrolled from April 21, 2006, to Feb 27, 2019 in 12 centres from five European countries (Switzerland, Spain, Italy, Poland, and Czech Republic). Patients were excluded if they presented with ST-segment-elevation myocardial infarction, did not have at least two serial high-sensitivity cardiac troponin I (hs-cTnI) measurements, or if the final diagnosis remained unclear. The final diagnosis was centrally adjudicated by two independent cardiologists using all available medical records, including serial hs-cTnI measurements and cardiac imaging. The primary outcome was type 1 NSTEMI. The performance of MI3 was directly compared with that of the ESC 0/1h-algorithm. Among 6487 patients, (median age 61·0 years [IQR 49·0-73·0]; 2122 [33%] female and 4365 [67%] male), 882 (13·6%) patients had type 1 NSTEMI. The median time difference between the first and second hs-cTnI measurement was 60·0 mins (IQR 57·0-70·0). MI3 performance was very good, with an area under the receiver-operating-characteristic curve of 0·961 (95% CI 0·957 to 0·965) and a good overall calibration (intercept -0·09 [-0·2 to 0·02]; slope 1·02 [0·97 to 1·08]). The originally defined MI3 score of less than 1·6 identified 4186 (64·5%) patients as low probability of having a type 1 NSTEMI (sensitivity 99·1% [95% CI 98·2 to 99·5]; negative predictive value [NPV] 99·8% [95% CI 99·6 to 99·9]) and an MI3 score of 49·7 or more identified 915 (14·1%) patients as high probability of having a type 1 NSTEMI (specificity 95·0% [94·3 to 95·5]; positive predictive value [PPV] 69·1% [66·0-72·0]). The sensitivity and NPV of the ESC 0/1h-algorithm were higher than that of MI3 (difference for sensitivity 0·88% [0·19 to 1·60], p=0·0082; difference for NPV 0·18% [0·05 to 0·32], p=0·016), and the rule-out efficacy was higher for MI3 (11% difference, p<0·0001). Specificity and PPV for MI3 were superior (difference for specificity 3·80% [3·24 to 4·36], p<0·0001; difference for PPV 7·84% [5·86 to 9·97], p<0·0001), and the rule-in efficacy was higher for the ESC 0/1h-algorithm (5·4% difference, p<0·0001). MI3 performs very well in diagnosing type 1 NSTEMI, demonstrating comparability to the ESC 0/1h-algorithm in an emergency department setting when using early serial blood draws.

Introduction: Despite advances in atrial fibrillation (AF) management, patients with AF continue to experience poor quality of life and adverse outcomes. Engagement of patients, caregivers, and clinicians to identify challenges in AF management can inform strategies to improve quality of life and improve AF related outcomes. Methods: We conducted virtual Human Centered Design (HCD) sessions with a) patients with AF and their caregivers to understand challenges in living with AF, and b) clinicians caring for patients with AF to identify difficulties encountered in AF management. During HCD sessions, we engaged participants to answer open-ended questions. Transcripts of audio recorded sessions were coded and emerging themes were identified. Results: 8 patients (25% African American, 13% Asian), 3 caregivers, and 7 clinicians participated in HCD sessions. Median (interquartile range) patient age was 69 years (58 - 78). Major themes from the patient and caregiver perspective included inadequate education on AF, lack of guidance on AF risk factor modification, lack of support networks, and absence of systems to guide patients when experiencing recurrent AF episodes. Major themes from the clinician perspective were complementary to patient and caregiver input. Themes included inadequate patient education due to limited time clinicians can spend with patients, lack of AF risk factor modification programs, and lack of streamlined services to allow timely communication with patients without increasing the administrative burden for physicians (Figure 1). Conclusions: A diverse group of patients, their caregivers, and clinicians identified lack of adequate education, guidance on AF risk factor modification as well as poorly structured patient-clinician communication as major challenges in AF care. Our findings are informing development of mobile health application addressing identified challenges with a goal to improve quality of life and adverse AF outcomes.
