Usefulness of Left Atrial Appendage Volume as a Predictor of Embolic Stroke in Patients With Atrial Fibrillation
In conclusion, larger LAA volume is associated with stroke in the setting of AF, and this measure can potentially improve risk stratification for stroke risk management in AF patients.

Impact of Increased Orifice Size and Decreased Flow Velocity of Left Atrial Appendage on Stroke in Nonvalvular Atrial Fibrillation
This study investigated whether a larger LAA orifice is related to decreased LAA flow velocity and stroke in nonvalvular AF. The dimension, morphology, and flow velocity of LAA were compared in patients with nonvalvular AF with (stroke group, n = 67, mean age 66 ± 9 years) and without ischemic stroke (no-stroke group, n = 151, mean age 56 ± 10 years). Compared with no-stroke group, the stroke group had larger LA dimension (4.7 ± 0.8 vs 4.2 ± 0.6 cm, p

A Comparison of Atrial Fibrillation Monitoring Strategies after Cryptogenic Stroke (From the CRYSTAL AF Trial)
Ischemic stroke etiology remains undetermined in 30% of cases, leading to a diagnosis of cryptogenic stroke. Paroxysmal atrial fibrillation (AF) is a major cause of ischemic stroke but may go undetected with short periods of ECG monitoring. The Cryptogenic Stroke and Underlying Atrial Fibrillation trial (CRYSTAL AF) demonstrated that long-term ECG monitoring with insertable cardiac monitors (ICM) is superior to conventional follow-up in detecting AF in the cryptogenic stroke population. We evaluated the sensitivity and negative predictive value (NPV) of various external monitoring techniques within a cryptogenic stroke cohort.

Relation of Low-Density Lipoprotein Cholesterol to Ischemic Stroke in Patients With Nonvalvular Atrial Fibrillation
Low-density lipoprotein cholesterol (LDL-C) has been demonstrated as an independent risk factor of ischemic stroke, but the association of LDL-C with ischemic stroke in patients with nonvalvular atrial fibrillation (AF) remains uncertain. Our objective was to explore whether LDL-C could refine stroke stratification in AF patients. A total of 424 nonvalvular AF patients with ischemic stroke and 391 ones without ischemic stroke were enrolled. No patient had received antithrombotic therapy. Multivariate logistic regression analysis showed that LDL-C was an independent predictor of ischemic stroke in AF patients, with the adju...

Underuse of oral anticoagulants in patients with ischemic stroke and atrial fibrillation in China
Anticoagulant therapy is an effective stroke prevention measure for people with atrial fibrillation (AF) who are at high risk of ischemic stroke. However, it is reported that oral anticoagulants (OACs) are generally underused in clinical practice. A better awareness of current usage of anticoagulant therapy would enable prevention of stroke secondary to AF. Therefore, we determined the nationwide prevalence of AF and the frequency of OACs use among patients with ischemic stroke in China. Based on the China National Stroke Screening Survey (CNSSS), a representative nationwide sample of 1,252,703 adults over 40 years old dur...

Meta-Analysis of Randomized Clinical Trials Comparing the Impact of Implantable Loop Recorder Versus Usual Care After Ischemic Stroke for Detection of Atrial Fibrillation and Stroke Risk
Implantable loop recorder (ILR) is recommended to detect subclinical atrial fibrillation (AF) after cryptogenic stroke; however, the clinical outcomes of this practice is unclear. We conducted a systematic review and meta-analysis of randomized controlled trials to evaluate 12-month AF detection, change in oral anticoagulation (OAC), and recurrent stroke in ILR versus usual care after ischemic stroke. We searched Medline, Embase, Web of Science, Cochrane Library for randomized controlled trials comparing ILR with usual care after any ischemic stroke.

Prevalence of and Risk Factors for Silent Ischemic Stroke in Patients With Atrial Fibrillation as Determined by Brain Magnetic Resonance Imaging
Varied silent ischemic stroke (SS) prevalence occurs in patients with atrial fibrillation (AF). Stroke history is worth 2 points in the CHADS2 scoring system. An unknown proportion of patients with AF with a CHADS2 score of 0 or 1 have been undertreated for stroke prevention. We investigated SS risk factors using magnetic resonance imaging and estimated SS impact on clinical outcomes in patients with AF. We analyzed a total of 1,200 patients (400 with AF and 800 with sinus rhythm) who had brain magnetic resonance imaging performed for routine health checkups. Clinical outcomes including symptomatic stroke, dementia, and co...

Effect of Obstructive Sleep Apnea on Frequency of Stroke in Patients with Atrial Fibrillation
Obstructive sleep apnea (OSA) is an independent risk factor for ischemic stroke that is not included in the usual cardioembolic risk assessments for patients with atrial fibrillation (AF). The aim of this study was to investigate the impact of OSA on stroke rate in patients with AF. Patients with AF and new diagnosis of OSA were identified from retrospective chart review. Those with a history of stroke at the time of the sleep study were excluded. The primary outcome was the incidence of stroke, determined by a physician investigator blinded to the results of polysomnography.

Meta-Analysis of Anticoagulation Use, Stroke, Thromboembolism, Bleeding, and Mortality in Patients With Atrial Fibrillation on Dialysis
Atrial fibrillation (AF) is common in patients on dialysis. Although randomized trials of anticoagulation for AF have demonstrated striking reductions in stroke, these trials did not recruit patients on dialysis. We thus undertook this systematic review and meta-analysis of observational studies including patients with AF on dialysis that reported associations of anticoagulation use. Twenty studies involving 529,741 subjects and 31,321 patients with AF on dialysis were identified. Anticoagulation was associated with a 45% (95% CI 13% to 88%) increased risk of any stroke, reflecting a nonsignificant 13% (95% CI −4% to 34...

High-Sensitivity C-Reactive Protein and Risk of Stroke in Atrial Fibrillation (from the Reasons for Geographic and Racial Differences in Stroke Study)
The relation between inflammation and prothrombotic state in atrial fibrillation (AF) is well recognized. This suggests a potential role for high-sensitivity C-reactive protein (hs-CRP), a marker of systemic inflammation, in improving prediction of stroke in participants with AF. Cox proportional hazard analysis was used to examine the risk of stroke in 25,841 participants (40% black and 55% women) with and without AF who were enrolled in the Reasons for Geographic and Racial Differences in Stroke study from 2003 to 2007.

Sex Differences in the Trends of Hospitalizations for Acute Stroke among Patients with Atrial Fibrillation in the United States; 2005 - 2014
Female sex was included in stroke prediction algorithms in an attempt to improve anticoagulation rates in women with atrial fibrillation (AF). It is unclear if these efforts reduced stroke burden in women with AF. In order to bridge this literature gap, using the Nationwide Inpatient Sample (NIS), we assessed sex differences in the trends of hospitalizations for stroke among patients with AF in the United States; 2005 – 2014. International classification of diseases, 9th revision, clinical modification (ICD-9-CM) codes were used to abstract AF and stroke diagnoses.
