Relationship between left atrial appendage morphology and stroke in patients with atrial fibrillation
Background: Atrial fibrillation (AF) is an important cause of stroke. Given the morbidity and mortality associated with stroke, the risk stratification of patients based on left atrial appendage (LAA) characteristics is of great interest.Objective: To explore the association between LAA morphology and LAA characteristics including the extent of trabeculations, orifice diameter, and length with prevalent stroke in a large cohort of patients with drug refractory AF who underwent AF ablation to develop mechanistic insight regarding the risk of stroke.Methods: An institutional cohort of 1063 patients referred for AF ablation f...

Atrial fibrillation ablation patients have long-term stroke rates similar to patients without atrial fibrillation regardless of CHADS2 score
Background: Atrial fibrillation (AF) is a leading cause of total and fatal ischemic stroke. Stroke risk after AF ablation appears to be favorably affected; however, it is largely unknown whether the benefit extends to all stroke CHADS2 risk profiles of AF patients.Objective: To determine if ablation of atrial fibrillation reduces stroke rates in all risk groups.Methods: A total of 4212 consecutive patients who underwent AF ablation were compared (1:4) with 16,848 age-/sex-matched controls with AF (no ablation) and to 16,848 age-/sex-matched controls without AF. Patients were enrolled from the large ongoing prospective Inte...

Po-713-05 ischemic stroke after prophylaxis with left atrial appendage closure vs non-warfarin oral anticoagulants: a “real-world” multicenter comparison of stroke severity
In randomized trials, strokes occurring in patients who have received left atrial appendage closure (LAAC) devices have been less severe than in patients receiving warfarin prophylaxis - an observation thought related to warfarin ’s higher rate of hemorrhagic stroke (which are known to have worse outcomes). Similar stroke rates have been described with LAAC vs NOACs (non-warfarin oral anticoagulants), but the low hemorrhagic stroke rate of NOACs raises the question of stroke severity between these two therapies.

Ce-543-01 4-fold higher rate of atrial fibrillation detection after stroke of presumed known etiology with continuous versus intermittent monitoring: results from the stroke af study
In patients (pts) with recent ischemic stroke, atrial fibrillation (AF) may be common regardless of the stroke etiology. Timely diagnosis and intervention may prevent more disabling recurrent strokes.

Po-693-03 atrial fibrillation in cryptogenic stroke: a real-world study with insertable cardiac monitor
Patients with cryptogenic stroke (CS) undergo insertable cardiac monitor (ICM) screen for occult atrial fibrillation (AF) as a possible ischemic stroke etiology. Continuous monitoring with ICM was shown to be superior to intermittent cardiac monitoring in the detection of AF in the CRYSTAL-AF Trial. However, there is limited real-world data about the rate of AF detection using ICM in patients with cryptogenic stroke.

Incidence and prediction of ischemic stroke among atrial fibrillation patients with end-stage renal disease requiring dialysis
Renal dysfunction is a significant risk factor for ischemic stroke in atrial fibrillation (AF). However, the incidence of ischemic stroke and how to predict its occurrence among AF patients with end-stage renal disease (ESRD) are unclear.

Stroke and Dementia Risk in Patients with and without Atrial Fibrillation and Carotid Arterial Disease
We sought to understand the risks of stroke, transient ischemic attack(TIA), and dementia in patients with and without atrial fibrillation (AF) and carotid arterial disease (CD), or a combination of both, and determine if therapies for each disease may influence risks. 11,572 patients were included and matched into 4 groups of 2,893 by the presence of AF and CD. CD and AF augment risk of stroke/TIA and dementia in the general population and the coexistence of both diseases is additive in risk. Ablation of AF was associated with lower risk, the magnitude of which was greater in those with CD.

B-po05-142 atrial fibrillation patient with low cha2ds2vasc score may still benefit from oral anticoagulation therapy for ischemic stroke prevention: the need to refine stroke risk assessment scores
The CHA2DS2VASC score has shown limitations in the assessment of ischemic stroke (IS) risk in atrial fibrillation (AF) patients.

B-po03-148 risk stratification for ischemic stroke and major bleeding in patients without atrial fibrillation - validity of cha2ds2-vasc and has-bled score
Atrial fibrillation (AF) is the most common arrhythmia. Recent cardiac implantable electronic devices (CIEDs) have led to an improvement in the early detection of AF episodes. ESC guidelines for the management of AF recommend the use of CHA2DS2-VASc score as class I to predict the risk of ischemic stroke in patients with AF. However, the validity of the CHA2DS2-VASc and HAS-BLED scores to predict ischemic stroke and major bleeding events in patients without AF remains unclear.

B-po02-045 utility of a smartphone connected electrocardiogram recorder for detecting atrial fibrillation in post-stroke patients
Atrial fibrillation is one of the important causes of ischemic stroke. Routine 24-hour monitoring reveals latent atrial fibrillation in up to about 5% of cases. Despite the fact that today there are many ways to record heart rate, there is no precise algorithm that allows to detect atrial fibrillation in patients who have survived ischemic stroke of unknown etiology.

Po-625-05 electrocardiographic deep terminal negative of the p wave in v1 and ischemic stroke:the atherosclerosis risk in communities (aric) study
Abnormal P-wave indices are associated with ischemic stroke independent of atrial fibrillation (AF). Deep terminal negative of the P wave in V1 (DTNPV1) is a simple ECG index that reflects underlying left atrial remodeling. However, it is unknown whether DTNPV1 is associated with ischemic stroke.

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.

Irregularity and lack of p-waves in short tachycardia episodes predict atrial fibrillation and ischemic stroke
Atrial fibrillation (AF) is defined as an irregular supraventricular tachycardia (SVT) without p-waves, with a duration>30s. It is not known whether AF characteristics in shorter SVT episodes predict AF and stroke.
