Ci-452768-1 impact of new-onset atrial fibrillation detected by cardiac implantable electronic devices on cardioembolic stroke events
The association between atrial fibrillation (AF) detected by implanted cardiac implantable electronic devices (CIEDs) and the incidence of cardioembolic stroke events has been reported. However, the cut-off value of new-onset AF duration detected by CIEDs for cardioembolic stroke is still unknown. In previous studies regarding the cut-off value of AF duration, patients who had a history of AF or had received anticoagulant therapies were also included. Therefore, the solo effect of AF on the risk of cardioembolic stroke cannot be reliably evaluated on these studies.

Does atrial fibrillation ablation really reduce stroke rates?
Atrial fibrillation (AF) is increasingly becoming common among older people, and its prevalence is around 1% of the adult population in North America (roughly 2.2 million people). Patients with AF have an increased risk of strokes, heart failure, and subsequent mortality. Although antiarrhythmic drugs for restoring sinus rhythm have failed to reduce these risks, a subanalysis showed that achieving sinus rhythm was associated with halving the mortality but this effect was negated if antiarrhythmic therapy was continued. In fact, the ATHENA (A placebo-controlled, double-blind, parallel-arm Trial to assess the efficacy of dro...

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.

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).

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.

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.
