Abstract
Atrial fibrillation is a frequent cardiac arrhythmia and is associated with an increased risk of cardioembolic stroke. The left atrial appendage is a finger-like extension originating from the main body of the left atrium and the main location of thrombus formation in patients with atrial fibrillation. Surgical or percutaneous left atrial appendage occlusion (LAAO) aims at preventing clot formation in the left atrial appendage. Here, we describe available surgical and percutaneous approaches to achieve LAAO and discuss the available evidence for LAAO in patients with atrial fibrillation. We discuss the role of LAAO and its role in stroke prevention in frequent scenarios in cerebrovascular medicine: LAAO as a potential alternative to oral anticoagulation in patients with a history of intracranial hemorrhage, and LAAO as a promising add-on therapy to direct oral anticoagulant therapy in patients with breakthrough stroke despite anticoagulation. Finally, we provide an outlook on currently ongoing trials that will provide further evidence in the next years.

Risk of Intracranial Hemorrhage Associated With Direct Oral Anticoagulation vs Antiplatelet Therapy: A Systematic Review and Meta-Analysis. JAMA Netw Open 2024; 7:e2449017. [PMID: 39630447 PMCID: PMC11618459 DOI: 10.1001/jamanetworkopen.2024.49017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2024] [Accepted: 10/11/2024] [Indexed: 12/08/2024] Open
Abstract
Importance For patients with atrial fibrillation, clinicians often prescribe antiplatelet therapy rather than oral anticoagulation, which may be related to a concern that direct oral anticoagulants (DOACs) are associated with a higher risk of intracranial bleeding, despite being less effective for stroke prevention. Objective To determine whether DOAC therapy, compared with single-agent antiplatelet therapy, was associated with an increased risk of intracranial and major hemorrhage. Data Sources A systematic search of PubMed and Embase databases from inception to February 7, 2024, was performed. Study Selection Randomized clinical trials that compared DOAC therapy with single-agent antiplatelet therapies were included. Trials with active follow-up of less than 30 days or a sample size less than 200 were excluded. Data Extraction and Synthesis The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. Data were extracted independently by 2 researchers. A random-effects meta-analysis model was used to report pooled treatment effects and 95% CIs. Main Outcomes and Measures The primary outcome was occurrence of intracranial hemorrhage. Results A total of 9 randomized clinical trials were included (45 494 participants). DOAC therapy was not associated with significantly higher odds of intracranial hemorrhage compared with antiplatelet therapy (0.55% vs 0.48% over a mean trial follow-up of 17.1 months; odds ratio [OR], 1.15; 95% CI, 0.71-1.88), but there was heterogeneity among trials (I2 = 53.7%). In an analysis by DOAC agent, the respective estimates for intracranial hemorrhage risk were as follows: rivaroxaban, OR, 2.09 (95% CI, 1.20-3.64); dabigatran, OR, 1.00 (95% CI, 0.61-1.64); and apixaban, OR, 0.72 (95% CI, 0.44-1.17). Overall, DOAC therapy was associated with higher odds of major hemorrhage compared with antiplatelet therapy (2.41% vs 1.76% over a mean trial follow-up of 15.5 months; OR, 1.39; 95% CI, 1.07-1.80), with the following estimates by agent: rivaroxaban, OR, 1.91 (95% CI, 1.22-3.00); dabigatran; OR, 1.21 (95% CI, 0.86-1.69); and apixaban, OR, 1.09 (95% CI, 0.73-1.63). Conclusions and Relevance In this systematic review and meta-analysis, DOAC therapy was not associated with a significantly higher risk of intracranial hemorrhage compared with antiplatelet therapy, but was associated with a higher risk of major hemorrhage. These findings support the safety of DOAC compared with antiplatelet therapy with respect to risk of ICH and reinforce adherence with current atrial fibrillation guidelines.

Abstract
Cardiovascular diseases (CVDs) continue to be a major global health concern, representing a leading cause of morbidity and mortality. This review provides a comprehensive examination of CVDs, encompassing their pathophysiology, diagnostic biomarkers, advanced imaging techniques, pharmacological treatments, surgical interventions, and the emerging role of herbal remedies. The review covers various cardiovascular conditions such as coronary artery disease, atherosclerosis, peripheral artery disease, deep vein thrombosis, pulmonary embolism, cardiomyopathy, rheumatic heart disease, hypertension, ischemic heart disease, heart failure, cerebrovascular diseases, and congenital heart defects. The review presents a wide range of cardiac biomarkers such as troponins, C-reactive protein, CKMB, BNP, NT-proBNP, galectin, adiponectin, IL-6, TNF-α, miRNAs, and oxylipins. Advanced molecular imaging techniques, including chest X-ray, ECG, ultrasound, CT, SPECT, PET, and MRI, have significantly enhanced our ability to visualize myocardial perfusion, plaque characterization, and cardiac function. Various synthetic drugs including statins, ACE inhibitors, ARBs, β-blockers, calcium channel blockers, antihypertensives, anticoagulants, and antiarrhythmics are fundamental in managing CVDs. Nonetheless, their side effects such as hepatic dysfunction, renal impairment, and bleeding risks necessitate careful monitoring and personalized treatment strategies. In addition to conventional therapies, herbal remedies have garnered attention for their potential cardiovascular benefits. Plant extracts and their bioactive compounds, such as flavonoids, phenolic acids, saponins, and alkaloids, offer promising cardioprotective effects and enhanced cardiovascular health. This review underscores the value of combining traditional and modern therapeutic approaches to improve cardiovascular outcomes. This review serves as a vital resource for researchers by integrating a broad spectrum of information on CVDs, diagnostic tools, imaging techniques, pharmacological treatments and their side effects, and the potential of herbal remedies.

Abstract
Atrial fibrillation (AF) is a prevalent cardiac arrhythmia associated with an increased risk of stroke due to disrupted heart function and potential clot formation. This review examines current management strategies for stroke prevention in AF, focusing on the efficacy, safety, and long-term outcomes of anticoagulation therapies. Anticoagulants, including novel oral anticoagulants (NOACs) and vitamin K antagonists, play a crucial role in reducing stroke risk by preventing clot formation in the heart. Recent studies highlight NOACs as superior alternatives to traditional therapies, offering improved safety profiles and enhanced patient adherence. Despite the risk of bleeding complications, judicious use of anticoagulants significantly improves clinical outcomes in AF patients. The review synthesizes evidence from clinical trials and meta-analyses to underscore the pivotal role of NOACs in transforming stroke prevention strategies in AF. Moreover, it discusses emerging interventions such as left atrial appendage occlusion and emphasizes the importance of personalized, patient-centered care in optimizing treatment decisions for AF patients at risk of stroke.

Eur Heart J Case Rep 2024; 8:ytae157. [PMID: 38707534 PMCID: PMC11065339 DOI: 10.1093/ehjcr/ytae157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 03/04/2024] [Accepted: 03/20/2024] [Indexed: 05/07/2024]
Abstract
Background Clinical practice guidelines recommend oral anticoagulation (OAC) for stroke prevention in selected patients with atrial fibrillation (AF). However, some patients still experience thrombo-embolic events despite adequate anticoagulation. The optimal management of these cases remains uncertain, leading to practice pattern variability. We present a series of three cases illustrating the use of left atrial appendage occlusion (LAAO) as an adjunctive stroke prevention strategy in AF patients with recurrent thrombo-embolic events despite adequate anticoagulation. Case summary Case one describes an 89-year-old female on apixaban who presented with a thrombus and underwent successful mechanical thrombectomy. Left atrial appendage occlusion was performed, and no subsequent thrombo-embolic events were reported. Case 2 involves a 72-year-old female on full-dose apixaban who experienced recurrent strokes despite adequate anticoagulation. Thrombectomy was performed twice, and complications arose during LAAO. The patient was discharged on warfarin + clopidogrel and remained event-free at the six-month follow-up. Case 3 features an 88-year-old female on rivaroxaban who experienced recurrent cerebral ischaemic events and gastrointestinal bleeding. Left atrial appendage occlusion using an Amplatzer Amulet™ device was successful, and the patient remained event-free at the one-year follow-up. Discussion This case series emphasizes the complexity of stroke prevention in AF patients and underscores the need for an individualized approach. Incorporating LAAO alongside OAC can provide additional stroke protection for patients with inadequate response to anticoagulation. Further randomized controlled trials are needed to evaluate the efficacy and safety of this approach. In light of the limited evidence available, these cases contribute to the growing body of knowledge on the potential role of LAAO in secondary stroke prevention in AF patients with recurrent thrombo-embolic events despite appropriate anticoagulation.

Abstract
Atrial fibrillation is one of the most common cardiac arrhythmias and is a major cause of ischaemic stroke. Recent findings indicate the importance of atrial fibrillation burden (device-detected, subclinical, or paroxysmal and persistent or permanent) and whether atrial fibrillation was known before stroke onset or diagnosed after stroke for the risk of recurrence. Secondary prevention in patients with atrial fibrillation and stroke aims to reduce the risk of recurrent ischaemic stroke. Findings from randomised controlled trials assessing the optimal timing to introduce direct oral anticoagulant therapy after a stroke show that early start (ie, within 48 h for minor to moderate strokes and within 4-5 days for large strokes) seems safe and could reduce the risk of early recurrence. Other promising developments regarding early rhythm control, left atrial appendage occlusion, and novel factor XI inhibitor oral anticoagulants suggest that these therapies have the potential to further reduce the risk of stroke. Secondary prevention strategies in patients with atrial fibrillation who have a stroke despite oral anticoagulation therapy is an unmet medical need. Research advances suggest a heterogeneous spectrum of causes, and ongoing trials are investigating new approaches for secondary prevention in this vulnerable patient group. In patients with atrial fibrillation and a history of intracerebral haemorrhage, the latest data from randomised controlled trials on stroke prevention shows that oral anticoagulation reduces the risk of ischaemic stroke but more data are needed to define the safety profile.

Abstract
AIMS Atrial fibrillation (AF) and heart failure (HF) often coexist. Older age is strongly associated with stroke, HF, and mortality. The association between coexistence of HF and a risk of clinical outcomes and the effectiveness of anticoagulation therapy including direct oral anticoagulants (DOACs) in elderly patients with AF and HF have not been investigated. We aimed to evaluate 2 years of outcomes and to elucidate the efficacy of DOACs or warfarin in elderly AF patients in the All Nippon AF In the Elderly (ANAFIE) Registry with and without a history of HF. METHODS AND RESULTS The ANAFIE Registry is a multicentre, prospective observational study following elderly non-valvular AF patients aged ≥75 years for 2 years. Hazard ratios (HRs) were calculated based on the presence or absence of an HF diagnosis and DOAC or warfarin use at enrolment. Among 32 275 eligible patients, 12 116 (37.5%) had been diagnosed with HF. Patients with HF had significantly higher rates of HF hospitalization or cardiovascular death (HR 1.94, P < 0.001), cardiovascular events (HR 1.59, P < 0.001), cardiovascular death (HR 1.49, P < 0.001), all-cause death (HR 1.32, P < 0.001), and net clinical outcome including stroke/systemic embolism, major bleeding, and all-cause death (HR 1.23, P < 0.001), compared with those without HF; however, HRs for stroke/systemic embolism (HR 0.96, P = 0.56) and major bleeding (HR 1.14, P = 0.13) were similar. DOAC use was associated with a low risk of stroke/systemic embolism (HR 0.86, P = 0.19 in HF; HR 0.79, P = 0.016 in non-HF; P for interaction = 0.56), major bleeding (HR 0.71, P = 0.008 in HF; HR 0.75, P = 0.016 in non-HF; P for interaction = 0.74), HF hospitalization or cardiovascular death (HR 0.81, P < 0.001 in HF; HR 0.78, P < 0.001 in non-HF; P for interaction = 0.26), cardiovascular events (HR 0.83, P < 0.001 in HF; HR 0.82, P = 0.001 in non-HF; P for interaction = 0.65), cardiovascular death (HR 0.84, P = 0.12 in HF; HR 0.75, P = 0.035 in non-HF; P for interaction = 0.18), all-cause death (HR 0.89, P = 0.082 in HF; HR 0.80, P = 0.001 in non-HF; P for interaction = 0.091), and net clinical outcome (HR 0.88, P = 0.019 in HF; HR 0.81, P < 0.001 in non-HF; P for interaction = 0.21) compared with warfarin, irrespective of the presence or absence of HF. Analysis using the propensity score matching method showed similar associations. CONCLUSIONS Non-valvular AF patients aged ≥75 years with a history of HF had higher risks of cardiovascular events and mortality. DOACs were favourable to warfarin regardless of the coexistence of HF. These results might encourage the use of DOACs in elderly patients with non-valvular AF with or without HF.

Abstract
BACKGROUND The safety and efficacy of oral anticoagulation for prevention of major adverse cardiovascular events in people with atrial fibrillation and spontaneous intracranial haemorrhage are uncertain. We planned to estimate the effects of starting versus avoiding oral anticoagulation in people with spontaneous intracranial haemorrhage and atrial fibrillation. METHODS In this prospective meta-analysis, we searched bibliographic databases and trial registries using the strategies of a Cochrane systematic review (CD012144) on June 23, 2023. We included clinical trials if they were registered, randomised, and included participants with spontaneous intracranial haemorrhage and atrial fibrillation who were assigned to either start long-term use of any oral anticoagulant agent or avoid oral anticoagulation (ie, placebo, open control, another antithrombotic agent, or another intervention for the prevention of major adverse cardiovascular events). We assessed eligible trials using the Cochrane Risk of Bias tool. We sought data for individual participants who had not opted out of data sharing from chief investigators of completed trials, pending completion of ongoing trials in 2028. The primary outcome was any stroke or cardiovascular death. We used individual participant data to construct a Cox regression model of the time to the first occurrence of outcome events during follow-up in the intention-to-treat dataset supplied by each trial, followed by meta-analysis using a fixed-effect inverse-variance model to generate a pooled estimate of the hazard ratio (HR) with 95% CI. This study is registered with PROSPERO, CRD42021246133. FINDINGS We identified four eligible trials; three were restricted to participants with atrial fibrillation and intracranial haemorrhage (SoSTART [NCT03153150], with 203 participants) or intracerebral haemorrhage (APACHE-AF [NCT02565693], with 101 participants, and NASPAF-ICH [NCT02998905], with 30 participants), and one included a subgroup of participants with previous intracranial haemorrhage (ELDERCARE-AF [NCT02801669], with 80 participants). After excluding two participants who opted out of data sharing, we included 412 participants (310 [75%] aged 75 years or older, 249 [60%] with CHA2DS2-VASc score ≤4, and 163 [40%] with CHA2DS2-VASc score >4). The intervention was a direct oral anticoagulant in 209 (99%) of 212 participants who were assigned to start oral anticoagulation, and the comparator was antiplatelet monotherapy in 67 (33%) of 200 participants assigned to avoid oral anticoagulation. The primary outcome of any stroke or cardiovascular death occurred in 29 (14%) of 212 participants who started oral anticoagulation versus 43 (22%) of 200 who avoided oral anticoagulation (pooled HR 0·68 [95% CI 0·42-1·10]; I2=0%). Oral anticoagulation reduced the risk of ischaemic major adverse cardiovascular events (nine [4%] of 212 vs 38 [19%] of 200; pooled HR 0·27 [95% CI 0·13-0·56]; I2=0%). There was no significant increase in haemorrhagic major adverse cardiovascular events (15 [7%] of 212 vs nine [5%] of 200; pooled HR 1·80 [95% CI 0·77-4·21]; I2=0%), death from any cause (38 [18%] of 212 vs 29 [15%] of 200; 1·29 [0·78-2·11]; I2=50%), or death or dependence after 1 year (78 [53%] of 147 vs 74 [51%] of 145; pooled odds ratio 1·12 [95% CI 0·70-1·79]; I2=0%). INTERPRETATION For people with atrial fibrillation and intracranial haemorrhage, oral anticoagulation had uncertain effects on the risk of any stroke or cardiovascular death (both overall and in subgroups), haemorrhagic major adverse cardiovascular events, and functional outcome. Oral anticoagulation reduced the risk of ischaemic major adverse cardiovascular events, which can inform clinical practice. These findings should encourage recruitment to, and completion of, ongoing trials. FUNDING British Heart Foundation.

Abstract
This focused update about antiplatelet agents to reduce the high risk of major adverse cardiovascular events after stroke due to spontaneous (nontraumatic) intracerebral hemorrhage (ICH) complements earlier updates about blood pressure-lowering, lipid-lowering, and oral anticoagulation or left atrial appendage occlusion for atrial fibrillation after ICH. When used for secondary prevention in people without ICH, antiplatelet agents reduce the risk of major adverse cardiovascular event (rate ratio, 0.81 [95% CI, 0.75-0.87]) and might increase the risk of ICH (rate ratio, 1.67 [95% CI, 0.97-2.90]). Before 2019, guidance for clinical decisions about antiplatelet agent use after ICH has focused on estimating patients' predicted absolute risks and severities of ischemic and hemorrhagic major adverse cardiovascular event and applying the known effects of these drugs in people without ICH to estimate whether individual ICH survivors in clinical practice might be helped or harmed by antiplatelet agents. In 2019, the main results of the RESTART (Restart or Stop Antithrombotics Randomized Trial) randomized controlled trial including 537 survivors of ICH associated with antithrombotic drug use showed, counterintuitively, that antiplatelet agents might not increase the risk of recurrent ICH compared to antiplatelet agent avoidance over 2 years of follow-up (12/268 [4%] versus 23/268 [9%]; adjusted hazard ratio, 0.51 [95% CI, 0.25-1.03]; P=0.060). Guidelines in the United States, Canada, China, and the United Kingdom and Ireland have classified the level of evidence as B and indicated that antiplatelet agents may be considered/reasonable after ICH associated with antithrombotic agent use. Three subsequent clinical trials have recruited another 174 participants with ICH, but they will not be sufficient to determine the effects of antiplatelet therapy on all major adverse cardiovascular events reliably when pooled with RESTART. Therefore, ASPIRING (Antiplatelet Secondary Prevention International Randomized Study After Intracerebral Hemorrhage) aims to recruit 4148 ICH survivors to determine the effects of antiplatelet agents after ICH definitively overall and in subgroups.

Abstract
PURPOSE The anti-thrombotic approach in individuals undergoing transcatheter aortic valve replacement (TAVR) mirrors a controversial field in clinical practice. METHODS/RESULTS The aim of this article was to critically appraise the randomized controlled GALILEO trial, where two different antithrombotic regimes (10 mg rivaroxaban + 3 months aspirin vs. aspirin + 3 months clopidogrel) were compared in patients who underwent TAVR as well as available evidence in literature in this field. CONCLUSION The GALILEO trial was prematurely terminated as a consequence of increased risk of both death or thromboembolic complications and a higher risk of bleeding in the anticoagulation arm, compared to the antiplatelet-based strategy. Various concerns have been raised that the negative results of the GALILEO trial need to be regarded with caution. A routine use of oral anticoagulation (OAC) for the prevention of atherothrombotic events and valve thrombosis after TAVR in individuals who do not have an indication for oral anticoagulation, can currently not be recommended when considering the evidence base of available literature. However, the negative results of the GALILEO trial need to be interpreted with caution - especially in terms of dose of rivaroxaban - and should not discourage from performing further trials investigating safety and efficacy of this therapeutic approach. Additionally, further dose-finding trials for rivaroxaban should be considered.

Abstract
Patients with atrial fibrillation (AF) experiencing ischemic stroke despite oral anticoagulation (OAC), i.e., breakthrough strokes, are not uncommon, and represent an important clinical subgroup in view of the consistently high risk of stroke recurrence and mortality. The understanding of the heterogenous potential mechanism underlying OAC failure is essential in order to implement specific therapeutic measures aimed at reducing the risk of recurrent ischemic stroke. However, due to the incomplete comprehension of this phenomenon and the limited available data, secondary stroke prevention in such high-risk patients represents a clinical dilemma. There are several available strategies to prevent ischemic stroke recurrence in AF patients with breakthrough stroke in the absence of competing causes unrelated to AF, and these include continuation or change in the type of OAC, addition of antiplatelet therapy, left atrial appendage closure, or any combination of the above options. However, due to the limited available data, the latest guidelines do not provide any specific recommendations about which of the above strategies may be preferred. This review describes the incidence, the clinical impact and the potential mechanisms underlying OAC failure in AF patients. Furthermore, the evidence supporting each of the above therapeutic options for secondary stroke prevention and the potential future directions will be discussed.

Abstract
Atrial fibrillation (AF) is an important risk factor for ischemic stroke (IS). Oral anticoagulation (OAC) significantly reduces the risk of IS in AF but also increases the risk of systemic bleeding, including intracerebral hemorrhage (ICH). AF-related strokes are associated with greater disability and mortality compared to non-AF strokes. The management of patients with AF-related strokes is challenging, and it involves weighing individual risks and benefits in the acute treatment and preventive strategies of these patients. This review summarizes the current knowledge of the acute management of ischemic and hemorrhagic stroke in patients with AF, and the prognosis and potential implications for management both in the acute and long-term setting.

Abstract
BACKGROUND Ischaemic stroke may occur despite antiplatelet therapy (APT). We aimed to investigate frequency, potential causes and outcomes in patients with ischaemic stroke despite APT. METHODS In this cohort study, we enrolled patients with imaging-confirmed ischaemic stroke from the Swiss Stroke Registry (01/2014-07/2022). We determined the frequency of prior APT, assessed stroke aetiology (modified TOAST classification) and determined the association of prior APT with unfavourable functional outcome (modified Rankin Scale score 3-6) and recurrent ischaemic stroke at 3 months using regression models. RESULTS Among 53,352 patients, 27,484 (51.5%) had no prior antithrombotic treatment, 17,760 (33.3%) were on APT, 7039 (13.2%) on anticoagulation and 1069 (2.0%) were on APT + anticoagulation. In patients with a history of ischaemic stroke/TIA (n = 11,948; 22.4%), 2401 (20.1%) had no prior antithrombotic therapy, 6594 (55.2%) were on APT, 2489 (20.8%) on anticoagulation and 464 (3.9%) on APT + anticoagulation. Amongst patients with ischaemic stroke despite APT, aetiology was large artery atherosclerosis in 19.8% (n = 3416), cardiac embolism in 23.6% (n = 4059), small vessel disease in 11.7% (n = 2011), other causes in 7.4% (n = 1267), more than one cause in 6.3% (n = 1078) and unknown cause in 31.3% (n = 5388). Prior APT was not independently associated with unfavourable outcome (aOR = 1.06; 95% CI: 0.98-1.14; p = 0.135) or death (aOR = 1.10; 95% CI: 0.99-1.21; p = 0.059) at 3-months but with increased odds of recurrent stroke (6.0% vs 4.3%; aOR 1.26; 95% CI: 1.11-1.44; p < 0.001). CONCLUSIONS One-third of ischaemic strokes occurred despite APT and 20% of patients with a history of ischaemic stroke had no antithrombotic therapy when having stroke recurrence. Aetiology of breakthrough strokes despite APT is heterogeneous and these patients are at increased risk of recurrent stroke.

Abstract
AIMS The prognosis of patients with atrial fibrillation (AF) and ischemic stroke while taking oral anticoagulation is poorly understood. This study aimed to characterize the outcomes of patients following a stroke event while on oral anticoagulation. METHODS AND RESULTS Individual participant data from five pivotal randomized trials of antithrombotic therapy in AF were used to assess the outcomes of patients with a post-randomization ischemic stroke while on study medication (warfarin, standard-, or lower-dose direct oral anticoagulant regimen) during trial follow-up. The primary outcome was recurrent ischemic stroke after the first post-randomization ischemic stroke. The primary analysis included 1163 patients with a first post-randomization ischemic stroke while on study medication (median age 73 years, 39.3% female, 35.4% history of stroke before trial enrollment). During a median continued follow-up of 337 days, 74 patients had a recurrent ischemic stroke [cumulative incidence at 1 year: 7.0%, 95% confidence interval (CI) 5.2%-8.7%]. The cumulative incidence of mortality at 3 months after stroke was 12.4% (95% CI 10.5%-14.4%). Consistent results for the incidence of recurrent ischemic stroke at 1 year were obtained in an analysis accounting for the competing risk of death (6.2%, 95% CI 4.8%-7.9%) and in a landmark analysis excluding the first 2 weeks after the index stroke and only including patients without permanent study drug discontinuation since then (6.8%, 95% CI 4.6%-8.9%). CONCLUSION Patients with AF and ischemic stroke while on oral anticoagulation are at increased risk of recurrent ischemic stroke and death. These patients currently have an unmet medical need.

Abstract
INTRODUCTION Obesity is a chronic disease, which has significant health consequences and is a staggering burden to health care systems. Obesity can have harmful effects on the cardiovascular system, including heart failure, hypertension, coronary heart disease, and atrial fibrillation (AF). One of the possible substrates might be epicardial adipose tissue (EAT), which can be the link between AF and obesity. EAT is a fat deposit located between the myocardium and the visceral pericardium. Numerous studies have demonstrated that EAT plays a pivotal role in this relationship regarding atrial fibrillation. AREAS COVERED This review will focus on the role of obesity and the occurrence of atrial fibrillation (AF) and examine the connection between these and epicardial adipose tissue (EAT). The first part of this review will explain the pathophysiology of EAT and its association with the occurrence of AF. Secondly, we will review bariatric and metabolic surgery and its effects on EAT and AF. EXPERT COMMENTARY In this review, the epidemiology, pathophysiology, and treatments methods of AF are explained. Secondly the effects on EAT were elucidated. Due to the complex pathophysiological link between EAT, AF, and obesity, it is still uncertain which treatment strategy is superior.
