Structural Integrity of Normal Appearing White Matter and Sex-Specific Outcomes After Acute Ischemic Stroke Brief Report
Background and Purpose—Women have worse poststroke outcomes than men. We evaluated sex-specific clinical and neuroimaging characteristics of white matter in association with functional recovery after acute ischemic stroke.Methods—We performed a retrospective analysis of acute ischemic stroke patients with admission brain MRI and 3- to 6-month modified Rankin Scale score. White matter hyperintensity and acute infarct volume were quantified on fluid-attenuated inversion recovery and diffusion tensor imaging MRI, respectively. Diffusivity anisotropy metrics were calculated in normal appearing white matter contralateral to...

Impact of Smoking on Clinical Outcome and Recanalization After Intravenous Thrombolysis for Stroke Clinical Sciences
Conclusions—Our study suggests that good outcome in smokers is mainly related to differences in baseline characteristics and not to biological effects of smoking. The higher recanalization rates in smokers, however, call for further studies.

Cost-Effectiveness of Apixaban, Dabigatran, Rivaroxaban, and Warfarin for Stroke Prevention in Atrial Fibrillation Clinical Sciences
Conclusions— In patients with nonvalvular atrial fibrillation and an increased risk of stroke prophylaxis, apixaban 5 mg, dabigatran 150 mg, and rivaroxaban 20 mg were all cost-effective alternatives to warfarin. The cost-effectiveness of novel oral anticoagulantss was dependent on therapy pricing in the United States and neurological events associated with rivaroxaban 20 mg.

Detection of Atrial Fibrillation After Ischemic Stroke or Transient Ischemic Attack: A Systematic Review and Meta-Analysis Clinical Sciences
Conclusions— Detection of AF was highly variable, and the review was limited by small sample sizes and marked heterogeneity. Further studies are required to inform patient selection, optimal timing, methods, and duration of monitoring for detection of AF/paroxysmal AF.

Supraventricular Premature Beats and Short Atrial Runs Predict Atrial Fibrillation in Continuously Monitored Patients With Cryptogenic Stroke Brief Reports
Conclusions— Numerous SPBs and SVRs demonstrated a high risk for future AF in patients with cryptogenic stroke.

Antithrombotic Therapy After Acute Ischemic Stroke in Patients With Atrial Fibrillation Clinical Sciences
Conclusions— Contrary to current guidelines, 30% of patients with atrial fibrillation and recent IS are not prescribed any OAC therapy on discharge, whereas a further 30% are prescribed combination OAC and antiplatelet therapy. Combination OAC and antiplatelet therapy in patients at high cardiovascular risk requires evaluation in clinical trials, particularly with the newer OACs, given their more favorable risk–benefit ratio compared with warfarin.

Detection of paroxysmal atrial fibrillation in stroke/tia patients.
Authors: Khan M, Miller DJ Abstract One-third of stroke and transient ischemic attack (TIA) are cryptogenic, and paroxysmal atrial fibrillation (PAF) has been suggested as a possible cause for these cryptogenic strokes. Multiple studies have recently evaluated long-term cardiac rhythm monitoring with good yield for PAF. The duration of monitoring varies between studies as well as the qualifying event definition. Moreover, the clinical significance of very brief atrial fibrillation events is unclear in the literature. This paper provides an overview of current advances in the detection of paroxysmal atrial fibrillat...

Type of Anesthesia and Differences in Clinical Outcome After Intra-Arterial Treatment for Ischemic Stroke Clinical Sciences
Conclusions— Our study suggests that patients with AIS of the anterior circulation undergoing IAT without GA have a higher probability of good clinical outcome compared with patients treated with general anesthesia.

Stroke and Embolic Events in Hypertrophic Cardiomyopathy: Risk Stratification in Patients Without Atrial Fibrillation Clinical Sciences
Conclusions— The incidence of stroke and embolic events was about 1.0% per year in the HCM cohort. AF had not been previously documented before the event in more than half of patients with events. Older age and enlarged left atrial dimension are possible risk factors for embolic events in patients with HCM without documented AF.

Stroke in Duchenne Muscular Dystrophy: A Retrospective Longitudinal Study in 54 Patients Brief Reports
Conclusions— This study indicates an increased risk for ischemic strokes in DMD patients. Regular cardiological assessment of all DMD patients is mandatory to evaluate the individual risk profile for cardioembolic events and to adapt therapeutic strategies.

FABS: An Intuitive Tool for Screening of Stroke Mimics in the Emergency Department Clinical Sciences
Conclusions— FABS seems to be reliable in stratifying SM from acute cerebral ischemia cases among patients in whom the head computed tomography was negative for any acute findings. It can help clinicians consider advanced imaging for further diagnosis.

Risk Factors and Cognitive Relevance of Cortical Cerebral Microinfarcts in Patients With Ischemic Stroke or Transient Ischemic Attack Clinical Sciences
Conclusions— Cortical CMIs are a common finding in patients with stroke/transient ischemic attack. Associations between CMI with atrial fibrillation and white matter hyperintensities suggest that these lesions have a heterogeneous cause, involving microembolism and cerebral small vessel disease. CMI seemed to preferentially impact visuospatial functions as assessed by a cognitive screening test.

Geographic Variation in the Use of Oral Anticoagulation Therapy in Stroke Prevention in Atrial Fibrillation Brief Report
Conclusions—Large geographic variation exists in oral anticoagulation use in atrial fibrillation. The use of oral anticoagulation is lower in the South, where the rates of stroke are unusually high. In the future, it will be important to analyze whether the high rates of stroke in the South can be partially attributed to the underuse of oral anticoagulation in this region.

Comparison of Clinical Risk Stratification for Predicting Stroke and Thromboembolism in Atrial Fibrillation Clinical Sciences
Conclusions— A direct comparison of 9 risk schemes reveals no profound differences in risk stratification accuracy for high-risk patients. Accurate prediction of low-risk patients is perhaps more valuable in determining those unlikely to benefit from oral anticoagulation therapy. Among our cohort, CHA2DS2-VASc performed best in this purpose.

Atrial Premature Beats Predict Atrial Fibrillation in Cryptogenic Stroke: Results From the EMBRACE Trial Clinical Sciences
Conclusions— Among older cryptogenic stroke or transient ischemic attack patients, the number of APBs on a routine 24-hour Holter ECG was a strong dose-dependent independent predictor of prevalent subclinical AF. Those with frequent APBs have a high probability of AF and represent ideal candidates for prolonged ECG monitoring for AF detection. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT00846924.
