In 2014, a joint consensus document dealing with the management of antithrombotic therapy in atrial fibrillation (AF) patients presenting with acute coronary syndrome (ACS) and/or undergoing percutaneous coronary or valve interventions was published, which represented an effort of the European Society of Cardiology Working Group on Thrombosis, European Heart Rhythm Association (EHRA), European Association of Percutaneous Cardiovascular Interventions (EAPCI), and European Association of Acute Cardiac Care (ACCA) endorsed by the Heart Rhythm Society (HRS) and Asia-Pacific Heart Rhythm Society (APHRS). Since publication of this document, additional data from observational cohorts, randomized controlled trials, and percutaneous interventions as well as new guidelines have been published. Moreover, new drugs and devices/interventions are also available, with an increasing evidence base. The approach to managing AF has also evolved towards a more integrated or holistic approach. In recognizing these advances since the last consensus document, EHRA, WG Thrombosis, EAPCI, and ACCA, with additional contributions from HRS, APHRS, Latin America Heart Rhythm Society (LAHRS), and Cardiac Arrhythmia Society of Southern Africa (CASSA), proposed a focused update, to include the new data, with the remit of comprehensively reviewing the available evidence and publishing a focused update consensus document on the management of antithrombotic therapy in AF patients presenting with ACS and/or undergoing percutaneous coronary or valve interventions, and providing up-to-date consensus recommendations for use in clinical practice.

Background To investigate baseline characteristics and long-term prognosis of carefully characterized asymptomatic and symptomatic patients with atrial fibrillation (AF) in a 'real-world' cohort of first-diagnosed non-valvular AF over a 10-year follow-up period. Methods and results We conducted an observational, non-interventional, and single-centre registry-based study of consecutive first-diagnosed AF patients. Of 1100 patients (mean age 52.7 ± 12.2 years and mean follow-up 9.9 ± 6.1 years), 146 (13.3%) had asymptomatic AF. Persistent or permanent AF, slower ventricular rate during AF (< 100/min), CHA2DS2-VASc score of 0, history of diabetes mellitus and male gender were independent baseline risk factors for asymptomatic AF presentation (all p < 0.01) with a good predictive ability of the multivariable model (c-statistic 0.86, p < 0.001). Kaplan-Meier 10-year estimates of survival free of progression of AF (log-rank test = 33.4, p < 0.001) and ischemic stroke (log-rank test = 6.2, p = 0.013) were significantly worse for patients with asymptomatic AF compared to those with symptomatic arrhythmia. In the multivariable Cox regression analysis, intermittent asymptomatic AF was significantly associated with progression to permanent AF (Hazard Ratio 1.6; 95% CI, 1.1-2.2; p = 0.009). Conclusions In a 'real-world' setting, patients with asymptomatic presentation of their first-diagnosed AF could have different risk profile and long-term outcomes compared to those with symptomatic AF. Whether more intensive monitoring and comprehensive AF management including AF ablation at early stage following the incident episode of AF and increased quality of oral anticoagulation could alter the long-term prognosis of these patients requires further investigation. © 2013 Elsevier Ireland Ltd.

At least 30 million people worldwide carry a diagnosis of atrial fibrillation (AF), and many more suffer from undiagnosed, subclinical, or 'silent' AF. Atrial fibrillation-related cardiovascular mortality and morbidity, including cardiovascular deaths, heart failure, stroke, and hospitalizations, remain unacceptably high, even when evidence-based therapies such as anticoagulation and rate control are used. Furthermore, it is still necessary to define how best to prevent AF, largely due to a lack of clinical measures that would allow identification of treatable causes of AF in any given patient. Hence, there are important unmet clinical and research needs in the evaluation and management of AF patients. The ensuing needs and opportunities for improving the quality of AF care were discussed during the fifth Atrial Fibrillation Network/European Heart Rhythm Association consensus conference in Nice, France, on 22 and 23 January 2015. Here, we report the outcome of this conference, with a focus on (i) learning from our 'neighbours' to improve AF care, (ii) patient-centred approaches to AF management, (iii) structured care of AF patients, (iv) improving the quality of AF treatment, and (v) personalization of AF management. This report ends with a list of priorities for research in AF patients. © 2015 Published on behalf of the European Society of Cardiology.

Background: The 4S-AF scheme includes stroke risk, symptoms, severity of burden, and substrate severity domain. Aim: We aimed to assess the adherence to the 4S-AF scheme in patients classified according to stroke risk in post hoc analysis of the BALKAN-AF dataset. Methods: A 14-week prospective enrolment of consecutive patients with electrocardiographically documented atrial fibrillation (AF) was performed in seven Balkan countries from 2014 to 2015. Results: Low stroke risk (CHA2DS2-VASc score, 0 in males or 1 in females) was present in 162 (6.0%) patients. 2 099 (77.4%) patients had CHA2DS2-VASc score ≥3 in females or ≥2 in males (high stroke risk), and 613 (22.6%) had CHA2DS2-VASc score <3 in females or <2 in males. Seventy-five (46.3%) patients with low stroke risk and 1555 (74.1%) patients with high stroke risk were prescribed oral anticoagulants (OAC). Two thousand six hundred and seventy-seven (98.6%) had data on European Heart Rhythm Association (EHRA) class. Among 2099 patients with high stroke risk, 703 (33.4%) had EHRA class ≥3. Two hundred and seven (29.4%) patients with EHRA class ≥3 and high stroke risk were offered rhythm control; 620 (55.2%) of individuals with first-diagnosed or paroxysmal AF with high stroke risk were offered rhythm control. Two or more comorbidities occurred in 1927 (91.8%) patients with high stroke risk. Conclusions: OAC overuse was observed in patients with low stroke risk, whilst OAC underuse was evident in those with high risk of stroke. The percentage of highly symptomatic patients with high risk of stroke who were offered a rhythm control strategy was low. © the Author(s), 2022.

INTRODUCTION The Atrial fibrillation Better Care (ABC) pathway provides a useful way of simplifying decision-making considerations in a holistic approach to atrial fibrillation management. OBJECTIVES To evaluate adherence to the ABC pathway and to determine major gaps in adherence in patients in the BALKAN-AF survey. PATIENTS AND METHODS In this ancillary analysis, patients from the BALKAN-AF survey were divided into the following groups: A (avoid stroke) + B (better symptom control) + C (cardiovascular and co- morbidity risk management)-adherent and -nonadherent management. RESULTS Among 2712 enrolled patients, 1013 (43.8%) patients with mean (SD) age of 68.8 (10.2) years and mean CHA2DS2-VASc score of 3.4 (1.8) had A+B+C-adherent management and 1299 (56.2%) had A+B+C-nonadherent management. Independent predictors of increased A+B+C-adherent manage- ment were: capital city (odds ratio [OR], 1.23; 95% CI, 1.03-1.46; P = 0.02), treatment by cardiologist (OR, 1.34; 95% CI, 1.08-1.66; P = 0.01), hypertension (OR, 2.2; 95% CI, 1.74-2.77; P <0.001), dia- betes mellitus (OR, 1.28; 95% CI, 1.05-1.57; P = 0.01), and multimorbidity (the presence of 2 or more long-term conditions) (OR, 1.85; 95% CI, 1.43-2.38; P <0.001). Independent predictors of decreased A+B+C-adherent management were: age 80 years or older (OR, 0.61; 95% CI, 0.48-0.76; P <0.001) and history of bleeding (OR, 0.5; 95% CI, 0.33-0.75; P = 0.001). CONCLUSIONS Physicians' adherence to integrated AF management based on the ABC pathway was suboptimal. Addressing the identified clinical and system-related factors associated with A+B+C-nonadherent manage- ment using targeted approaches is needed to optimize treatment of patients with AF in the Balkan region. © by Medycyna Praktyczna, Kraków 2020

Many patients with atrial fibrillation (AF) who are in need of stroke prevention are not treated with oral anticoagulation or discontinue treatment shortly after its initiation. Despite the availability of direct oral anticoagulants (DOACs), such undertreatment has improved somewhat but is still evident. This is due to continued risks of bleeding events or ischemic strokes while on DOAC, poor treatment compliance, or aversion to anticoagulant therapy. Because of significant improvements in procedural safety over the years left atrial appendage closure (LAAC), using a catheter-based, device implantation approach, is increasingly favored for the prevention of thromboembolic events in AF patients who cannot have long-term oral anticoagulation. This article is an executive summary of a practical guide recently published by an international expert consensus group, which introduces the LAAC devices and briefly explains the implantation technique. The indications and device follow-up are more comprehensively described. This practical guide, aligned with published guideline/guidance, is aimed at those non-implanting physicians who may need to refer patients for consideration of LAAC. © 2024. Thieme.

Background: Evidence increasingly shows that the risk of thrombotic complications in COVID-19 is associated with a hypercoagulable state. Several organizations have released guidelines for the management of COVID-19-related coagulopathy and prevention of VTE. However, an urgent need exists for practical guidance on the management of arterial thrombosis and thromboembolism in this setting. Research Question: What is the current available evidence informing the prevention and management of arterial thrombosis and thromboembolism in patients with COVID-19? Study Design and Methods: A group of approved panelists developed key clinical questions by using the Population, Intervention, Comparator, and Outcome (PICO) format that address urgent clinical questions regarding prevention and management of arterial thrombosis and thromboembolism in patients with COVID-19. Using MEDLINE via PubMed, a literature search was conducted and references were screened for inclusion. Data from included studies were summarized and reviewed by the panel. Consensus for the direction and strength of recommendations was achieved using a modified Delphi survey. Results: The review and analysis of the literature based on 11 PICO questions resulted in 11 recommendations. Overall, a low quality of evidence specific to the population with COVID-19 was found. Consequently, many of the recommendations were based on indirect evidence and prior guidelines in similar populations without COVID-19. Interpretation: The existing evidence and panel consensus do not suggest a major departure from the management of arterial thrombosis according to recommendations predating the COVID-19 pandemic. Data on the optimal strategies for prevention and management of arterial thrombosis and thromboembolism in patients with COVID-19 are sparse. More high-quality evidence is needed to inform management strategies in these patients. © 2023 American College of Chest Physicians

The use of triple antithrombotic therapy (TAT) consisting of an oral anticoagulant (OAC), aspirin, and a P2Y12 inhibitor in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) and / or undergoing percutaneous coronary intervention (PCI) is associated with a high risk of bleeding. Recently, several randomized clinical trials tested the hypothesis as to whether dual antithrombotic therapy (DAT) regimens (consisting of an OAC and a single antiplatelet drug) may be safer in terms of bleeding events as compared with TAT. They also investigated the role of non–vitamin K antagonist oral anticoagulants (NOACs) as a part of DAT and TAT. The purpose of this review is to provide an overview of available evidence regarding the safety and efficacy of DAT compared with TAT regimens, international guidelines recommendations, knowledge gaps, and unmet needs in the management of patients with AF and ACS and / or undergoing PCI. © 2020 Medycyna Praktyczna Cholerzyn.

Whilst there is a clear clinical benefit of oral anticoagulation (OAC) in patients with atrial fibrillation (AF) and venous thromboembolism (VTE) in reducing the risks of thromboembolism, major bleeding events (especially intracranial bleeds) may still occur and be devastating. The decision to initiate and continue anticoagulation is often based on a careful assessment of both the thromboembolism and bleeding risk. The more common and validated bleeding risk factors have been used to formulate bleeding risk stratification scores, but thromboembolism and bleeding risk factors often overlap. Also, many factors that increase bleeding risk are transient and modifiable, such as variable international normalized ratio values, surgical procedures, vascular procedures, or drug–drug and food–drug interactions. Bleeding risk is also not a static ‘one off’ assessment based on baseline factors but is dynamic, being influenced by ageing, incident comorbidities, and drug therapies. In this Consensus Document, we comprehensively review the published evidence and propose a consensus on bleeding risk assessments in patients with AF and VTE, with the view to summarizing ‘best practice’ when approaching antithrombotic therapy in these patients. We address the epidemiology and size of the problem of bleeding risk in AF and VTE, review established bleeding risk factors, and summarize definitions of bleeding. Patient values and preferences, balancing the risk of bleeding against thromboembolism are reviewed, and the prognostic implications of bleeding are discussed. We propose consensus statements that may help to define evidence gaps and assist in everyday clinical practice. © 2022 Authors. All rights reserved.

Introduction: Patient-reported treatment burden (TBN) refers to the patient’s time and effort invested in the management of their chronic health conditions. The aim of this research was to explore TBN in patients with coronary artery disease (CAD). Methods: Consecutive patients with chronic medical condition(s) were invited to complete the study questionnaires (TBN and EQ-5D). Results: Of 514 enrolled patients, 116 (22.6%) patients had CAD. The mean TBN score for CAD vs. non-CAD was 40.49 ±21.54 and 46.17 ±21.44 (p = 0.023), respectively. Conclusions: Patients with CAD could have a lower TBN in comparison to patients with other chronic medical conditions. © 2024 Termedia & Banach.

Stroke prevention is central to the management of patients with atrial fibrillation (AF) which has moved towards a more holistic or integrative care approach. The published evidence suggests that management of AF patients following such a holistic approach based on the Atrial fibrillation Better Care (ABC) pathway is associated with a lower risk of stroke and adverse events. Risk assessment, re-assessment and use of direct oral anticoagulants (DOACs) are important for stroke prevention in AF. The stroke and bleeding risks of AF patients are not static and should be re-assessed regularly. Bleeding risk assessment is to address and mitigate modifiable bleeding risk factors, and to identify high bleeding risk patients for early review and follow-up. Well-controlled comorbidities and healthy lifestyles also play an important role to achieve a better clinical outcome. Digital health solutions are increasingly relevant in the diagnosis and management of patients with AF, with the potential to improve stroke prevention. In this review, we provide an update on stroke prevention in AF, including importance of holistic management, risk assessment/re-assessment, and stroke prevention for special AF populations. Evidence-based and structured management of AF patients would reduce the risk of stroke and other adverse events. © 2023 The Author(s)

Brugada syndrome (BrS) is one of the commonest inherited primary arrhythmia syndromes typically presenting with arrhythmic syncope or sudden cardiac death (SCD) due to polymorphic ventricular tachycardia and ventricular fibrillation precipitated by vagotonia or fever in apparently healthy adults, less frequently in children. The prevalence of the syndrome (0.01%–0.3%) varies among regions and ethnicities, being the highest in Southeast Asia. BrS is diagnosed by the “coved type” ST-segment elevation ≥ 2 mm followed by a negative T-wave in ≥ 1 of the right precordial leads V 1 –V 2 . The typical electrocardiogram in BrS is often concealed by fluctuations between normal, non-diagnostic and diagnostic ST-segment pattern in the same patient, thus hindering the diagnosis. Presently, the majority of BrS patients is incidentally diagnosed, and may remain asymptomatic for their lifetime. However, BrS is responsible for 4–12% of all SCDs and for ~ 20% of SCDs in patients with structurally normal hearts. Arrhythmic risk is the highest in SCD survivors and in patients with spontaneous BrS electrocardiogram and arrhythmic syncope, but risk stratification for SCD in asymptomatic subjects has not yet been fully defined. Recent achievements have expanded our understanding of the genetics and electrophysiological mechanisms underlying BrS, while radiofrequency catheter ablation may be an effective new approach to treat ventricular tachyarrhythmias in BrS patients with arrhythmic storms. The present review summarizes our contemporary understanding and recent advances in the inheritance, pathophysiology, clinical assessment and treatment of BrS patients. © 2017

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

Aims: The 4S-AF scheme [Stroke risk, Symptom severity, Severity of atrial fibrillation (AF) burden, Substrate severity] has recently been described as a novel approach to in-depth characterization of AF. We aim to determine if the 4S-AF scheme would be useful for AF characterization and provides prognostic information in real-world AF patients. Methods and results: The Spanish and French cohorts of the EORP-AF Long-Term General Registry were included. The baseline 4S-AF scheme was calculated and related to the primary management strategy (rhythm or rate control). Follow-up was performed at 1-year with all-cause mortality and the composite of ischaemic stroke/transient ischaemic attack/systemic embolism, major bleeding, and all-cause death, as primary endpoints. A total of 1479 patients [36.9% females, median age 72 interquartile range (IQR 64-80) years] were included. The median 4S-AF scheme score was 5 (IQR 4-7). The 4S-AF scheme, as continuous and as categorical, was associated with the management strategy decided for the patient (both P < 0.001). The predictive performances of the 4S-AF scheme for the actual management strategy were appropriate in its continuous [c-index 0.77, 95% confidence interval (CI) 0.75-0.80] and categorical (c-index 0.75, 95% CI 0.72-0.78) forms. Cox regression analyses showed that 'red category' classified patients in the 4S-AF scheme had a higher risk of all-cause death (aHR 1.75, 95% CI 1.02-2.99) and composite outcomes (aHR 1.60, 95% CI 1.05-2.44). Conclusion: Characterization of AF by using the 4S-AF scheme may aid in identifying AF patients that would be managed by rhythm or rate control and could also help in identifying high-risk AF patients for worse clinical outcomes in a 'real-world' setting. © 2021 Published on behalf of the European Society of Cardiology.

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

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

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

Background Risk stratification in patients with atrial fibrillation (AF) is important to facilitate guideline-directed therapies. The Calculator of Absolute Stroke Risk (CARS) scheme enables an individualized estimation of 1-year absolute risk of stroke in AF. We aimed to investigate the predicted and absolute risks of ischaemic stroke, and evaluate whether CARS (and CHA2DS2VASc score) may be useful for identifying high risk patients with AF despite contemporary treatment. Methods We utilized the EORP-AF General Long-Term Registry which prospectively enrolled patients with AF from 250 centres across 27 participating European countries. Patients with sufficient data to determine CARS and CHA2DS2-VASc score, and reported outcomes of ischaemic stroke were included in this analysis. The primary outcome of ischaemic stroke was recorded over a 2-year follow-up period. Results A total of 9444 patients were included (mean age 69.1 [±11.4] years; 3776 [40.0%] females). There was a high uptake (87.9%) of anticoagulation therapy, predominantly with vitamin K antagonist (50.0%). Over a mean follow-up period of 24 months, there were a total of 101 (1.1%) ischaemic stroke events. In the entire cohort, the median CARS and absolute annual risks of ischaemic stroke were 2.60 (IQR 1.60–4.00) and 0.53% (95%CI 0.43–0.64%), respectively. There was no statistical difference between the predictive performance of CARS and CHA2DS2-VASc score (0.621 [95%CI 0.563–0.678] vs. 0.626 [95%CI 0.573–0.680], P = 0.725). Conclusion Contemporary management of AF was associated with a low risk of ischaemic stroke. CARS and CHA2DS2-VASc score may be useful to identify high risk patients despite treatment who may benefit from more aggressive treatment and follow-up. © The Author(s) 2022.

COVID-19 is associated with endothelial activation in the setting of a potent inflammatory reaction and a hypercoagulable state. The end result of this thromboinflammatory state is an excess in thrombotic events, in particular venous thromboembolism. Pulmonary embolism (PE) has been of special interest in patients with COVID-19 given its association with respiratory deterioration, increased risk of intensive care unit admission, and prolonged hospital stay. The pathophysiology and clinical characteristics of COVID-19-associated PE may differ from the conventional non-COVID-19-associated PE. In addition to embolic events from deep vein thrombi, in situ pulmonary thrombosis, particularly in smaller vascular beds, may be relevant in patients with COVID-19. Appropriate prevention of thrombotic events in COVID-19 has therefore become of critical interest. Several changes in viral biology, vaccination, and treatment management during the pandemic may have resulted in changes in incidence trends. This review provides an overview of the pathophysiology, epidemiology, clinical characteristics, and risk factors of COVID-19-associated PE. Furthermore, we briefly summarize the results from randomized controlled trials of preventive antithrombotic therapies in COVID-19, focusing on their findings related to PE. We discuss the acute treatment of COVID-19-associated PE, which is substantially similar to the management of conventional non-COVID-19 PE. Ultimately, we comment on the current knowledge gaps in the evidence and the future directions in the treatment and follow-up of COVID-19-associated PE, including long-term management, and its possible association with long-COVID. © 2022.
