Underutilization of Ambulatory ECG Monitoring After Stroke and Transient Ischemic Attack: Missed Opportunities for Atrial Fibrillation Detection Clinical Sciences
Conclusions— Less than one third of patients in our cohort received guideline-recommended 24-hour Holter monitoring, and <1% received prolonged ambulatory ECG monitoring. These findings highlight a modifiable evidence-practice gap that likely contributes to an overdiagnosis of strokes as cryptogenic, an underdiagnosis of atrial fibrillation, and missed anticoagulant treatment opportunities for secondary stroke prevention.

Australian Public's Awareness of Stroke Warning Signs Improves After National Multimedia Campaigns Brief Reports
Conclusions— The Australian public’s awareness of stroke warning signs has improved since commencement of the NSF campaigns commensurate with greater awareness of stroke advertising. Public education efforts are worthwhile, and future efforts should focus on groups identified with low awareness or those at high risk of stroke.

Use of Warfarin at Discharge Among Acute Ischemic Stroke Patients With Nonvalvular Atrial Fibrillation in China Clinical Sciences
Conclusions— The rate of warfarin use remains low among patients with ischemic stroke and known nonvalvular atrial fibrillation in China. Hospital size and academic status together with patient age, heart failure, heavy alcohol drinking, international normalized ratio in hospital, and stroke severity on admission were each independently associated with the use of warfarin at discharge. There is much room for improvement for secondary stroke prevention in nonvalvular atrial fibrillation patients in China.

Ischemic Stroke Risk in Patients With Atrial Fibrillation and CHA2DS2-VASc Score of 1: Systematic Review and Meta-Analysis Brief Reports
Conclusions— Our meta-analysis of ischemic stroke risk in atrial fibrillation patients suggests that those with CHA2DS2-VASc score of 1 may be considered for a novel oral anticoagulant, but because of high heterogeneity, the decision should be based on individual patient characteristics.

Rates and Determinants of 5-Year Outcomes After Atrial Fibrillation-Related Stroke: A Population Study Clinical Sciences
Conclusions— AF-stroke is associated with considerable long-term morbidity, fatality, stroke recurrence, and nursing home requirement. Adequately resourced national AF strategies to improve AF detection and prevention are needed.

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.

Acute Hospital, Community, and Indirect Costs of Stroke Associated With Atrial Fibrillation: Population-Based Study Clinical Sciences
Conclusions— In our population study, AF-stroke was associated with substantially higher total, acute hospital, nursing home, and general practitioner costs per patient. Targeted programs to identify AF and prevent AF-stroke may have significant economic benefits, in addition to health benefits.

Left Atrial Enlargement and Stroke Recurrence: The Northern Manhattan Stroke Study Clinical Sciences
Conclusion— Moderate to severe LAE was an independent marker of recurrent cardioembolic or cryptogenic stroke in a multiethnic cohort of ischemic stroke patients. Further research is needed to determine whether anticoagulant use may reduce risk of recurrence in ischemic stroke patients with moderate to severe LAE.

Role of Prestroke Vascular Pathology in Long-Term Prognosis After Stroke: The Rotterdam Study Clinical Sciences
Conclusions— One quarter of deaths after stroke could theoretically be prevented with rigorous cardiovascular prevention and treatment, but this should preferably start before stroke occurrence. In addition, research into factors explaining the remaining deaths needs to be encouraged.

One-Year Incidence, Time Trends, and Predictors of Recurrent Ischemic Stroke in Sweden From 1998 to 2010 Clinical Sciences
Conclusions—The risk of recurrent ischemic stroke decreased from 1998 to 2010. Well-known risk factors for stroke were associated with a higher risk of ischemic stroke recurrence; whereas, secondary preventive medication was associated with a reduced risk, emphasizing the importance of secondary preventive treatment.

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.

Quality of Care and Outcomes for In-Hospital Ischemic Stroke: Findings From the National Get With The Guidelines-Stroke Clinical Sciences
Conclusions— Compared with community-onset ischemic stroke, patients with in-hospital stroke experienced more severe strokes, received lower adherence to process-based quality measures, and had worse outcomes. These findings suggest there is an important opportunity for targeted quality improvement efforts for patients with in-hospital stroke.

Assessing the Performance of the Framingham Stroke Risk Score in the Reasons for Geographic and Racial Differences in Stroke Cohort Clinical Sciences
Conclusions— Although higher FSRS was associated with higher stroke risk, the FSRS overestimated the observed stroke rates in this study, particularly in certain subgroups. This may be because of temporal declines in stroke rates, secular trends in prevention treatments, or differences in populations studied. More accurate estimates of event rates are critical for planning research, including clinical trials, and targeting health-care efforts.

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.
