Hp-574-04 associations between obesity parameters and the risk of incident atrial fibrillation and ischemic stroke in different age groups: a nationwide population-based study
Atrial fibrillation (AF) and ischemic stroke (IS) are two representative cardiovascular diseases. They share common metabolic risk factors such as obesity and ageing is an important predisposing factor. Limited data comprehensively evaluated the relationship between obesity measurements - body mass index (BMI) and waist circumference (WC) - and incident AF and IS in the different age groups.

Ca-532-03 association between sleep apnea, atrial fibrillation and incident stroke in a very large population of young individuals
Sleep apnea (SA) worsens outcomes in patients with atrial fibrillation/flutter (AF), and both are common in young patients (20-50 years). However, it is unreported what proportion of young patients with SA have or will develop AF or stroke.

Ce-539-02 utilization of oral anticoagulation after bleeding events in stroke patients with atrial fibrillation
Oral anticoagulation (OAC) is recommended for stroke prophylaxis after diagnosis of atrial fibrillation (AF). However, the optimal strategy or timing for continuing OAC use after bleeding events in these patients has not been well established.

Po-656-08 insertable cardiac monitor in cryptogenic stroke: left atrial size, atrial ectopic burden, and atrial fibrillation
Insertable cardiac monitor (ICM) is a proven useful tool for the detection of subclinical atrial fibrillation (AF) in patients with embolic stroke of undetermined source (ESUS).

Po-05-218 atrial myopathy forms the substrate for ischemic stroke in patients without atrial fibrillation: secondary analysis of topcat trial.
Around 25% of all ischemic strokes do not have an etiology despite a complete standardized diagnostic workup. Recent studies emphasized the effect of atrial dysfunction on arrhythmogenesis and thrombogenesis. At present, there is a lack of a direct link between atrial myopathy and ischemic stroke independently of atrial fibrillation (AF).

Po-03-005 best anticoagulation strategy for stroke prophylaxis in atrial fibrillation patients with amyloidosis
A considerable proportion of elderly patients are known to have coexistent atrial fibrillation (AF) and amyloidosis. Both conditions increase stroke risk.

Po-01-220 invasively diagnosed hfpef in af associated with functional remodelling of the left atrial appendage: implications for stroke risk
HFpEF commonly coexists with atrial fibrillation (AF). The influence of coexisting HFpEF on function of the left atrial appendage (LAA) and risk of stroke remains unknown.

Po-01-140 atrial fibrillation and septic shock: a five-year retrospective observational study of anticoagulation usage, bleeding and stroke rates
Anticoagulation (AC) for atrial fibrillation (AF) is a cornerstone of management, and the benefit of mitigating stroke risk is accompanied by an increased risk of bleeding. The risk and benefit of AC in septic shock remains unclear as this disruptive hyperinflammatory state leads to multi-organ dysfunction, which can include coagulopathies.

Dh-452784-2 identifying atrial fibrillation with sinus rhythm electrocardiogram using artificial intelligence in embolic stroke with undetermined source
Previous studies have demonstrated acceptable ranges of accuracy of artificial intelligence (AI) algorithms for identifying patients with paroxysmal atrial fibrillation (AF) based on their sinus rhythm electrocardiograms (ECGs). However, none of them has been validated in patients with embolic stroke with undetermined source (ESUS) in which thorough AF screening is required.

Left atrial appendage closure: A new technique for clinical practice
Conclusion: This review concludes that it is now appropriate to consider these techniques for patients with AF who are at high risk for stroke for whom effective conventional or novel anticoagulant therapy is not available or who present problems in managing drug treatment.

Editorial Commentary: Anticoagulation for atrial fibrillation in dialysis patients: What is known and what does the future hold?
The association between atrial fibrillation and stroke is well established and, in the general population, anticoagulation with warfarin can reduce the incidence of stroke by 60% with an acceptable bleeding risk.1, 2 Patients who are on hemodialysis have an increased prevalence of atrial fibrillation possibly secondary to comorbid conditions and hemodialysis itself causing dramatic swings in fluid and electrolytes and affecting cardiac dimensions.3 There are also substantially higher rates of ischemic stroke in this population attributable both to frequently co-occurring traditional stroke risk factors as well as the incre...

Outcomes of Percutaneous Left Atrial Appendage Occlusion Device Implantation in Patients with Rheumatic Atrial Fibrillation
Patients with atrial fibrillation (AF) and rheumatic heart disease (RHD) disease have a 17-fold increased risk of stroke, and in comparison, those with AF without RHD have a 5-fold increased risk of stroke (1). However, the contemporary trials of pharmaceutical and device therapies have systematically excluded patients with AF and RHD. While Vitamin K antagonist remains the favored approach to mitigate stroke risk in patients with RHD and AF, the optimal strategy for preventing stroke in patients with RHD-associated AF who cannot tolerate oral anticoagulation therapy remains unknown (1).
