High Prevalence of Atrial Fibrillation Among Patients With Ischemic Stroke Clinical Sciences
Conclusions— Access to nationwide register data shows that AF is more common among patients with ischemic stroke than those previously reported. Few patients with stroke and AF had anticoagulant treatment before the event, and few got it after the event. CHA2DS2-VASc could be a useful monitoring tool to intensify efforts to diagnose AF among patients with cryptogenic stroke.

Paroxysmal Supraventricular Tachycardia and the Risk of Ischemic Stroke Clinical Sciences
Conclusions— In a large and demographically diverse sample of patients, we found an independent association between PSVT and ischemic stroke. PSVT seems to be a novel risk factor that may account for some proportion of strokes that are currently classified as cryptogenic.

Predictors of Finding Occult Atrial Fibrillation After Cryptogenic Stroke Clinical Sciences
Conclusions— Mobile cardiac outpatient telemetry detects AF in a substantial proportion of cryptogenic stroke patients. Age >60 years and radiographic evidence of prior cortical or cerebellar infarction are robust indicators of occult AF. Patients with neither had a low prevalence of AF.

Electrocardiographic Left Atrial Abnormality and Risk of Stroke: Northern Manhattan Study Clinical Sciences
Conclusions— ECG-defined left atrial abnormality was associated with incident cryptogenic or cardioembolic stroke independently of the presence of AF, suggesting atrial thromboembolism may occur without recognized AF.

Abnormal P-Wave Axis and Ischemic Stroke Clinical Sciences
Conclusions—aPWA is independently associated with ischemic stroke. This association seems to be stronger for cardioembolic strokes. Collectively, our findings suggest that alterations in atrial electric activation may predispose to cardiac thromboembolism independent of atrial fibrillation.

Atrial Fibrillation, Stroke Risk, and Warfarin Therapy Revisited: A Population-Based Study Clinical Sciences
Conclusions— AF is more common than present guidelines suggest. The attributable risk of AF for ischemic stroke increases with age and is close to that of hypertension in individuals aged ≥80 years. Because a majority of patients with AF with increased risk for stroke had not received anticoagulation therapy, there is a large potential for improvement.

Improved Detection of Silent Atrial Fibrillation Using 72-Hour Holter ECG in Patients With Ischemic Stroke: A Prospective Multicenter Cohort Study Clinical Sciences
Conclusions— In unselected survivors of stroke or TIA, 72-hour ECG monitoring is feasible and improves the detection rate of silent paroxysmal AF.

P-Wave Morphology and the Risk of Incident Ischemic Stroke in the Multi-Ethnic Study of Atherosclerosis Brief Reports
Conclusions— We found an association between baseline P-wave morphology and incident stroke even after accounting for AF. This association may reflect an atrial cardiopathy that leads to stroke in the absence of AF.

CHA2DS2-VASc Score (Congestive Heart Failure, Hypertension, Age >=75 Doubled, Diabetes Mellitus, Prior Stroke or Transient Ischemic Attack Doubled, Vascular Disease, Age 65-74, Female) for Stroke in Asian Patients With Atrial Fibrillation Clinical Sciences
Background and Purpose—The CHA2DS2-VASc stroke score (congestive heart failure, hypertension, age ≥75 (doubled), diabetes mellitus, prior stroke or transient ischemic attack (doubled), vascular disease, age 65–74, female) is used in most guidelines for risk stratification in atrial fibrillation (AF), but most data for this score have been derived in Western populations. Ethnic differences in stroke risk may be present. Our objective was to investigate risk factors for stroke in AF and application of the CHA2DS2-VASc score in an Asian AF population from Korea.Methods—A total of 5855 oral anticoagulant–naive nonval...

Statin Adherence Is Associated With Reduced Recurrent Stroke Risk in Patients With or Without Atrial Fibrillation Clinical Sciences
Conclusions—The relationship between statin adherence and reduced recurrent stroke risk is as strong among patients with AFib as it is among patients without AFib, suggesting that AFib status should not be a reason to exclude patients from secondary stroke prevention with a statin.

Noninvasive Cardiac Event Monitoring to Detect Atrial Fibrillation After Ischemic Stroke: A Randomized, Controlled Trial Clinical Sciences
Conclusions— Routine noninvasive cardiac-event monitoring after acute stroke enhances detection of paroxysmal AF and early anticoagulation. Extended monitoring should be offered to all eligible patients soon after acute stroke. Guidelines on investigation for AF in stroke patients could be strengthened.

Effectiveness and Safety of Apixaban, Dabigatran, and Rivaroxaban Versus Warfarin in Patients With Nonvalvular Atrial Fibrillation and Previous Stroke or Transient Ischemic Attack Clinical Sciences
Conclusions—Results from our study of the 3 NOACs versus warfarin in nonvalvular atrial fibrillation patients with a previous history of stroke/transient ischemic attack are relatively consistent with their respective phase III trials and previous stroke/transient ischemic attack subgroup analyses. All NOACs seemed no worse than warfarin in respect to ischemic stroke, ICH, or major bleeding risk.

Pilot Randomized Trial of Outpatient Cardiac Monitoring After Cryptogenic Stroke Brief Reports
Conclusions— In the first reported randomized trial of cardiac monitoring after cryptogenic stroke, the rate of AF detection was lower than expected, incidental arrhythmias were frequent, and compliance with monitoring was suboptimal. Our findings highlight the challenges of prospectively identifying stroke patients at risk for harboring paroxysmal AF and ensuring adequate compliance with cardiac monitoring.

Atrial Cardiopathy and the Risk of Ischemic Stroke in the CHS (Cardiovascular Health Study) Clinical Sciences
Conclusions—In addition to clinically apparent AF, other evidence of abnormal atrial substrate is associated with subsequent ischemic stroke. This finding is consistent with the hypothesis that thromboembolism from the left atrium may occur in the setting of several different manifestations of atrial disease.

Patients With Ischemic Stroke and Incident Atrial Fibrillation: A Nationwide Cohort Study Clinical Sciences
Conclusions— Ischemic stroke was associated with a substantially increased risk of incident AF, particularly among individuals with higher CHADS2 or CHA2DS2-VASc scores. These risk scores seem to be simple tools for identifying patients at higher risk of incident AF after ischemic stroke.
