Ce-454029-4 racial disparities in the use of oral anticoagulation for atrial fibrillation by sex and within high and low stroke risk populations
Atrial fibrillation (AF) is the most common arrhythmia and is associated with an increased risk of ischemic stroke. Oral anticoagulation (OAC) has been shown to reduce the risk of ischemic stroke in patients with AF. Previous studies have demonstrated that both females and Black, Hispanic, and Asian groups are less likely to be prescribed OAC.

Po-701-01 nine month readmission rates and clinical outcomes of anticoagulation versus watchman device in octogenarians
Atrial Fibrillation (AF), the most common arrhythmia in older adults, is fraught with an increased risk of stroke. Studies which have demonstrated non-inferiority of Left atrial appendage occlusion (LAAO) with a watchman device compared to oral anticoagulation for stroke risk reduction in AF did not include patients greater than 80 years of age, making it difficult to generalize these results to this population.

Ce-543-04 inter-atrial block identifies patients with low cha2ds2-vasc score but high stroke risk
Beyond current methods of risk stratification, clinical studies employing machine learning methodology have demonstrated that the 12-lead ECG harbors additional prognostic information for various cardiovascular outcomes. Interatrial block (IAB) manifests as P wave duration>120 msec and is associated with thromboembolism, atrial arrhythmias, and mortality.

Po-669-06 brain metabolism in patients with atrial fibrillation: insights from a pilot fdg-pet study
Atrial Fibrillation (AF) is an independent risk factor for incident dementia. Overt stroke, microembolism and microbleeds are among the main mechanisms linking this arrhythmia and cognitive dysfunction. Cerebral hypoperfusion related to beat-to-beat blood flow variation during AF can also explain the occurrence of dementia or mild cognitive impairment, as rhythm control strategies were shown to reduce its incidence. However, data regarding brain metabolism patterns in patients with AF are still scarce.

B-po02-051 atrial arrhythmia detection using insertable cardiac monitor in patients with cryptogenic stroke: a real-word cohort study
AF can be the underlying cause of cryptogenic strokes (CS). CRYSTAL-AF demonstrated that 30% developed AF by 36 months using an insertable cardiac Monitor (ICM) in patients with CS.

Anticoagulation for Stroke Prevention in Patients With Hypertrophic Cardiomyopathy and Atrial Fibrillation: A Review
Atrial fibrillation is the most common arrhythmia in patients with hypertrophic cardiomyopathy with a prevalence and incidence of 23% and 3.1% respectively. The risk of thromboembolism is high in patients with hypertrophic cardiomyopathy regardless of the CHADS2VASC score. This review includes five observational studies that focused on prevention of thromboembolism in patients with hypertrophic cardiomyopathy and atrial fibrillation. These papers evaluated and compared outcomes between patients on either warfarin or direct oral anticoagulants.

Is A Little Atrial Fibrillation Still Too Much?
Atrial fibrillation (AF) is most often viewed as a dichotomous variable, one that is either entirely present or absent. Guidelines support this perspective by recommending anticoagulation based on underlying stroke risk without regard to AF “type”, duration, or burden.1 The use of cardiac monitoring, however, has allowed us to quantify AF and associate outcomes with various arrhythmia characteristics.2, 3 These types of studies have raised legitimate doubts as to whether the 30 second threshold used to define AF is associated with meaningful consequences and have created equipoise for sub-clinical AF episodes lasting minutes to hours.

Atrial Fibrillation and Cognitive Decline —Another Piece for a Big Puzzle
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, and its prevalence is increasing over time.1, 2 AF is associated with an increased risk of stroke,3 heart failure,4 and death.5-7 In recent years, evidence has emerged to indicate that AF is associated with another growing public health problem: cognitive impairment and dementia.8 Although the evidence is compelling, existing studies suffer from several limitations such as reliance on the Mini-Mental State Examination, cross-sectional design, and lack of attention to domain-specific changes.

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.

Increasing time between first diagnosis of atrial fibrillation and catheter ablation adversely affects long-term outcomes
Conclusion: Delays in treatment with catheter ablation impact procedural success rates independent of temporal changes to the AF subtype at ablation.
