Glycated Hemoglobin and Risk of First Episode Stroke in Diabetic Patients with Atrial Fibrillation: A Cohort Study
Diabetes is associated with increased risk of stroke in patients with atrial fibrillation. Whether glycemic control, evaluated by glycated hemoglobin, affects the risk of stroke in diabetic patients with atrial fibrillation remains unknown.

Risk of stroke after catheter ablation versus cardioversion for atrial fibrillation: a propensity matched study of 24,244 patients
Stroke is the major cause of morbidity and mortality related to atrial fibrillation (AF). Catheter ablation for AF is effective in reducing AF burden, but its impact on long-term stroke risk is unknown.

HRS/NSA 2014 Survey of Atrial Fibrillation and Stroke: Gaps in Knowledge and Perspective, Opportunities for Improvement
The prevalence of atrial fibrillation (AF) is substantial and increasing. Stroke is common in AF and can have devastating consequences. Oral anticoagulants are effective in reducing stroke risk, but are underutilized.

Volume and Morphology of Left Atrial Appendage as Determinants of Stroke Subtype in Patients with Atrial Fibrillation
Atrial fibrillation (AF) is a leading cause of stroke, but not all cases of stroke in patients with AF are due to AF.

Atrial fibrillation ablation, stroke and mortality. Evaluating the effects of therapy in the era of big data
Atrial fibrillation (AF) is associated with an increased stroke and mortality risk. The logical extension of this is that if AF is controlled or eliminated then patient outcomes with respect to stroke and mortality should improve. The AFFIRM trial comparing rate and rhythm control strategies unfortunately did not demonstrate an improvement in either of these endpoints in the rhythm control population (1). An interesting sub-analysis of the AFFIRM trial did however indicate that patients who were in sinus rhythm more often at the time of their follow-up had a reduced mortality (2).

Atrial fibrillation ablation, stroke, and mortality: Evaluating the effects of therapy in the era of big data
Atrial fibrillation (AF) is associated with an increased stroke and mortality risk. The logical extension of this is that if AF is controlled or eliminated then patient outcomes with respect to stroke and mortality should improve. The Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) trial1 comparing rate and rhythm control strategies unfortunately did not demonstrate an improvement in either of these end points in the rhythm control population. An interesting subanalysis of the AFFIRM trial2 did, however, indicate that patients who were in sinus rhythm more often at the time of their follow-up had a reduced mortality.

Race and stroke in an atrial fibrillation inception cohort: Findings from the Penn Atrial Fibrillation Free study
Stroke may be the initial manifestation of atrial fibrillation (AF). Limited studies, however, have evaluated racial differences in stroke before the diagnosis of AF.

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-po02-079 performance of atrial fibrillation burden patterns detected via insertable cardiac monitor for stroke risk stratification
Atrial fibrillation (AF) is associated with increased stroke risk, yet limitations in conventional monitoring restrict our understanding of AF burden risk thresholds. Predictive algorithms incorporating continuous monitoring data may be useful for stroke prediction.

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.

B-po01-028 utilization of cardiac monitoring for atrial fibrillation in cryptogenic stroke patients
Atrial fibrillation (AF) is found in ∼1/3 of cryptogenic stroke (CS) patients after long-term monitoring with an insertable cardiac monitor (ICM), enabling the use of anticoagulants for recurrent stroke prevention. However, little is known about monitoring pathways prior to ICM in this population.
