Insular Cortex Lesions, Cardiac Troponin, and Detection of Previously Unknown Atrial Fibrillation in Acute Ischemic Stroke: Insights From the Troponin Elevation in Acute Ischemic Stroke Study Clinical Sciences
Conclusions— Insular cortex involvement, higher admission high-sensitivity cardiac troponin T, older age, hypertension, and longer monitoring are associated with new detection of AF during in-hospital ECG monitoring. Patients with higher high-sensitivity cardiac troponin T or insular cortex involvement may be candidates for prolonged ECG monitoring.

Clinical and Economic Implications of Apixaban Versus Aspirin in the Low-Risk Nonvalvular Atrial Fibrillation Patients Clinical Sciences
Conclusions— Anticoagulant treatment with apixaban versus aspirin in low-risk patients, as identified using CHADS2 or CHA2DS2–VASc, is projected to increase life expectancy and provide clinical benefits that are cost effective.

Does Prior Use of Beta Blockers Affect Functional Outcomes Post Ischemic Stroke Endovascular Intervention? (P5.296)
Conclusions:Prior use of beta blockers did not lead to better functional outcomes (MRS ≤2) in acute ischemic stroke patients undergoing EVI.

To Treat or Not to Treat Clinical Sciences
Conclusions—Given the patient characteristics in this study, there is room for more patients to be treated with anticoagulants, without hemorrhages to prevail. In nonagenarians, hemorrhages increased somewhat more, but this did not affect the overall outcome in this age stratum.

Some light in the shadows of atrial fibrillation and stroke: To look or not to look
In ischemic stroke, the diagnostic workup determines the best preventive strategy. However, cryptogenic stroke accounts for about 20%–40% of all strokes.1 For these patients, the best preventive treatment remains unknown, and most guidelines recommend risk factor modification and antiplatelet therapy. Given the substantial recurrence rate for cryptogenic stroke, this is not a comfortable situation: just try to tell your stroke patients, "After all these tests, I do not have any clue why you had a stroke"; and about the treatment, "Just take an aspirin and cross fingers you do not have another one."

Safety Outcomes After Percutaneous Transcatheter Closure of Patent Foramen Ovale Clinical Sciences
Conclusions—Approximately 1 in 14 patients who underwent percutaneous transcatheter PFO closure after ischemic stroke or TIA experienced a serious periprocedural adverse outcome or death. The risk of adverse outcomes was highest in older patients and in those with preceding ischemic stroke.

External Validation of the ISAN, A2DS2, and AIS-APS Scores for Predicting Stroke-Associated Pneumonia
The Prestroke Independence, Sex, Age, National Institutes of Health Stroke Scale (ISAN), Age, Atrial Fibrillation, Dysphagia, male sex, and National Institutes of Health Stroke Scale (A2DS2), and acute ischemic stroke-associated pneumonia score (AIS-APS) scores were created to predict stroke-associated pneumonia (SAP), one of the most important medical stroke complications. External validation of all such scores in an acute stroke population was the aim of our study.

Electrocardiographic RR Interval Dynamic Analysis to Identify Acute Stroke Patients at High Risk for Atrial Fibrillation Episodes During Stroke Unit Admission
AbstractPatients at short-term risk of paroxysmal atrial fibrillation (PAF) often exhibit increased RR interval variability during sinus rhythm. We studied if RR dynamic analysis, applied in the first hours after stroke unit (SU) admission, identified acute ischemic stroke patients at higher risk for subsequent PAF episodes detected within the SU hospitalization. Acute ischemic stroke patients underwent continuous cardiac monitoring (CCM) using standard bedside monitors immediately after SU admission. The CCM tracks from the first 48  h were analyzed using a telemedicine service (SRA clinic, Apoplex Medical, Germany). Bas...

Prevalence of Nonstenotic Carotid Plaque in Stroke Due to Atrial Fibrillation Compared to Embolic Stroke of Undetermined Source
Background: Embolic stroke of undetermined source (ESUS) accounts for about 20% of strokes. Nonstenotic cervical arterial plaque may be a mechanism of stroke in a subset of these patients. Methods: A cohort of consecutive patients with ischemic stroke was retrospectively identified from a stroke registry. Patients with unilateral anterior circulation embolic stroke due to atrial fibrillation (AF) or consistent with ESUS who underwent computed tomographic neck angiography were included. The prespecified primary outcome was a comparison of the prevalence of carotid plaque greater than or equal to 3 mm thickness ipsilateral v...

Differential effect of mechanical thrombectomy and intravenous thrombolysis in atrial fibrillation associated stroke
Conclusions In patients treated with MT, comorbid AF is associated with faster procedural time, fewer passes, and increased rates of first pass success without increased risk of intracranial hemorrhage or worse functional outcomes. These results are in contrast to the increased hemorrhage rates and worse functional outcomes observed in AF associated stroke treated with supportive care and or IVT. These data suggest that MT negates the AF penalty in ischemic stroke.

Another possible determinant for ischemic stroke with nonvalvular atrial fibrillation other than conventional oral anticoagulant treatment: The relationship between whole blood viscosity and stroke ☆
Prevention of ischemic stroke complication of atrial fibrillation (AF) is the crucial target in the disease. Stroke is largely prevented by warfarin and the introduction of new oral anticoagulants. While warfarin reduces stroke by 60 –70%, new oral anticoagulants provide at least equal success to this reduction with appropriate dose and treatment compliance.1,2 Nonetheless, we still encounter thromboembolic ischemic stroke in clinical practice in AF patients taking oral anticoagulants (OAC) and once experienced, stroke can hav e devastating consequences for the patients.

Incidence of atrial fibrillation detected by implantable loop recorders in unexplained stroke
Conclusion: In patients with unexplained stroke, AF was detected by ILR in 25.5%. Predictors of AF were identified, which may help to target investigations. ILRs may have a central role in the future in the investigation of patients with unexplained stroke.
