Comparisons of CHADS and CHADS-VASc scores for stroke risk stratification in atrial fibrillation: Which scoring system should be used for Asians?
Both U.S. and European guidelines recommend use of the CHA2DS2-VASc rather than CHADS2 score for stroke risk stratification in atrial fibrillation (AF). However, the CHA2DS2-VASc score has not been proved to be better than CHADS2 score for Asians in a large-scale study.

Over One Year Efficacy and Safety of Left Atrial Appendage Occlusion Novel Oral Anticoagulants for Stroke Prevention in Atrial Fibrillation: A Systematic Review and Meta-analysis of Randomized Controlled Trials and Observational Studies
Direct comparison of the efficacy and safety profile between left atrial appendage occlusion (LAAO) devices and novel oral anticoagulants (NOACs) for stroke prevention in atrial fibrillation (AF) is warranted but currently unavailable.

Over 1-year efficacy and safety of left atrial appendage occlusion versus novel oral anticoagulants for stroke prevention in atrial fibrillation: A systematic review and meta-analysis of randomized controlled trials and observational studies
A direct comparison of the efficacy and safety profiles of left atrial appendage occlusion (LAAO) devices and novel oral anticoagulants (NOACs) for stroke prevention in atrial fibrillation is warranted but currently unavailable.

Warfarin Use and the Risk of Mortality, Stroke, and Bleeding in Hemodialysis Patients with Atrial Fibrillation
The optimal management of stroke prophylaxis in hemodialysis patients with atrial fibrillation is controversial.

Benefits of non –vitamin K antagonist oral anticoagulants in patients with atrial fibrillation go beyond stroke prevention
The last decade has produced a large body of robust randomized controlled trial (RCT) data investigating the use of non –vitamin K antagonist oral anticoagulants (NOACs) in nonvalvular atrial fibrillation (AF).1–4 Compared with warfarin, dabigatran and apixaban have been found to reduce the combined outcome of stroke and systemic embolism. In addition, apixaban and edoxaban significantly reduce major bleeding. Fu rthermore, a pooled meta-analysis has demonstrated superior efficacy and overall safety of the NOACs.

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.

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 duration>30 seconds. Whether AF characteristics during short SVT episodes predict AF and stroke is not known.

Seasonal variation in the risk of ischemic stroke in patients with atrial fibrillation: A nationwide cohort study
Several cardiovascular diseases exhibit seasonal variations, but data about cold temperature and risk of ischemic stroke in patients with atrial fibrillation (AF) are limited.

A New Model to Predict Ischemic Stroke in Patients with Atrial Fibrillation Using Warfarin or Direct Oral Anticoagulants
Stroke risk stratification scores (e.g., CHA2DS2-VASc) are used to tailor therapeutic recommendations for patients with atrial fibrillation (AF) in different risk groups.

Refining the Prediction of Stroke in Atrial Fibrillation. An elusive endeavor
Atrial fibrillation (AF), the most common sustained arrhythmia, is responsible for>20% of all strokes.1 AF-associated strokes are more severe, causing significantly greater long-term disability, accounting for greater resource utilization, and result in significantly higher mortality when compared to non-AF strokes.2-4 Oral anticoagulants (OACs) are the standard of care for the prevention of AF-associated stroke and systemic thromboembolism. To date OACs are the only therapeutic intervention that has been consistently and definitively shown to improve survival in the AF population.

Impact of atrial fibrillation/flutter on the in-hospital mortality of ischemic stroke patients
Stroke is the second leading cause of death worldwide. Ischemic strokes, which are caused by atrial fibrillation/flutter (AF) may be more devastating than those without AF.

The Decrease in Peak Atrial Longitudinal Strain in Patients with Atrial Fibrillation as a Practical Parameter for Stroke Risk Stratification
Decreased peak atrial longitudinal strain (LA strain) derived from two-dimensional speckle tracking is frequently observed in patients with atrial fibrillation (AF) and associated with the risk of ischemic stroke.

Predictors of ischemic stroke for low-risk patients with atrial fibrillation: A matched case-control study
The predictors of ischemic stroke in ‘low-risk’ patients with atrial fibrillation (AF) (CHA2DS2-VASc score 0 in men or 1 in women) are debated.
