Paroxysmal Atrial Fibrillation in Cryptogenic Stroke: A Case–Control Study
Conclusions: Very short episodes of PAF are common in patients with CS and with SKC, but their pathogenic significance is unclear. Predominance of PAF in younger patients with CS and embolic infarct pattern suggests a causative role in these cases. More research is needed before prolonged cardiac rhythm monitoring can be recommended to guide anticoagulation in CS patients.

Outcome of 312 Japanese Patients with Carotid Endarterectomy and Factors Associated with Cardiovascular Events—A Single-center Study in Japan
Background: There have only been a few reports regarding the outcomes and risk factors after CEA. To clarify the factors associated with outcome in patients with carotid stenosis who underwent carotid endarterectomy (CEA), we investigated cardiovascular events and mortality in the Kyushu Medical Center in Japan.Methods: We consecutively registered patients with significant carotid stenosis who had CEA performed over 10 years and compared the incidences of stroke, myocardial infarction, and death. On admission, we evaluated medical records for stroke risk factors, including hypertension, diabetes mellitus, hypercholesterol...

Dilemma of Indication for Thrombolysis in a Patient with Acute Ischemic Stroke Treated with a Novel Oral Anticoagulant
We report the case of a patient treated with dabigatran who developed acute ischemic stroke and was considered for thrombolysis. Because of the prolonged thrombin time (TT), thrombolysis was not performed. Repeated coagulation tests 5 days after stroke, with unchanged anticoagulant (dabigatran) treatment, found 2-fold higher TT and activated partial thromboplastin time (APTT) compared with the values found in the acute stage. Routine coagulation tests (TT and APTT) do not reliably reflect the coagulation features of a patient; therefore, there is an urgent need to develop reliable biomarkers and an adequate guideline to ...

Predictors of Acute Stroke Mimics in 8187 Patients Referred to a Stroke Service
Conclusions: One third of the patients seen by a stroke team over 10 years had a stroke mimic. Factors associated with a stroke mimic may be ascertained by an emergency physician before calling the stroke team.

Association between Paroxysmal Atrial Fibrillation and the Left Atrial Appendage Ejection Fraction during Sinus Rhythm in the Acute Stage of Stroke: A Transesophageal Echocardiographic Study
This study aimed to investigate whether left atrial appendage (LAA) dysfunction evaluated by transesophageal echocardiography (TEE) during sinus rhythm is predictable of paroxysmal atrial fibrillation (PAF) as an embolic source in the acute stage of stroke.Methods and Results: We measured and analyzed LAA flow velocity (LAA-FV) and LAA ejection fraction (LAA-EF) in 300 acute ischemic stroke patients by TEE. We divided the acute ischemic stroke patients into 3 groups. The atrial fibrillation (AF) group (n = 58) comprised patients whose TEE was performed during AF rhythm. The PAF group (n = 42) comprised patients with a hist...

Higher Frequency of Atrial Fibrillation Linked to Colder Seasons and Air Temperature on the Day of Ischemic Stroke Onset
Background: Whether a seasonal variation of atrial fibrillation among acute ischemic stroke (AIS) patients occurs is unknown. We studied the distribution of atrial fibrillation across seasons and air temperatures in a cohort of AIS patients.Methods: We selected 899 AIS patients from the Argentinean Stroke Registry (ReNACer), who were admitted to 43 centers in the Province of Buenos Aires. We recorded the minimum and maximum temperatures at local weather centers on the day and the city where each stroke occurred. We used the goodness-of-fit χ2 test to assess the distribution of atrial fibrillation across seasons and air te...

Electrocardiographic Assessment of Coronary Artery Disease and Stroke Risk Factors in Rural and Urban Tanzania: A Case–control Study
Conclusions: This is the first published study of ECG assessment of CAD and other stroke risk factors in an incident population of stroke cases in sub-Saharan Africa. It suggests that concomitant CAD in black African stroke cases is more common than previously suggested.

Fatal Multiple Systemic Emboli after Intravenous Thrombolysis for Cardioembolic Stroke
Our objective is to present a case of fatal multiple systemic emboli after intravenous thrombolysis for cardioembolic stroke. A 64-year-old woman with atrial fibrillation was admitted for evaluation of sudden consciousness disturbance, right hemiplegia, and aphasia. Diffusion-weighted imaging showed no early ischemic changes of the brain, and magnetic resonance angiography (MRA) showed occlusion of the left middle cerebral artery (MCA). One hour after initiation of 0.6 mg/kg of intravenous alteplase, the MCA was partially recanalized. Her symptoms disappeared the following day. We began intravenous heparin for secondary pr...

The CHA(2)DS(2)-VASc Score Reflects Clinical Outcomes in Nonvalvular Atrial Fibrillation Patients with an Initial Cardioembolic Stroke
Conclusions: The severity of NVAF-induced initial cardioembolic stroke increased with higher CHA(2)DS(2)-VASc scores, and the outcomes were poor. The present study suggests that the CHA(2)DS(2)-VASc score may be useful not only for the evaluation of stroke risk but also for the prediction of clinical outcomes after stroke.

Bleeding Complications Associated with Warfarin Treatment in Ischemic Stroke Patients with Atrial Fibrillation: A Population-Based Cohort Study
Background: Bleeding events are the major obstacle to the widespread use of warfarin for secondary stroke prevention. Previous studies have not examined the use of risk stratification scores to estimate lifetime bleeding risk associated with warfarin treatment in a population-based setting. The purpose of this study is to determine the lifetime risk of bleeding events in ischemic stroke patients with atrial fibrillation (AF) undergoing warfarin treatment in a population-based cohort and to evaluate the use of bleeding risk scores to identify patients at high risk for lifetime bleeding events.Methods: The resources of the R...

Aspirin Therapy and Risk of Subdural Hematoma: Meta-analysis of Randomized Clinical Trials
Conclusions: Based on the limited available data, it is uncertain whether aspirin therapy increases the risk of subdural hematoma: the observed 1.6-fold increased risk was not statistically significant. The incidence of subdural hematoma during aspirin therapy is low but varies widely depending upon the age of the patient population.

Examination Timing and Lesion Patterns in Diffusion-weighted Magnetic Resonance Imaging of Patients with Classically Defined Transient Ischemic Attack
Conclusions: Acute ischemic lesions on DWI were associated with time-to-DWI and LAA in patients with classically defined TIA. Additionally, we identified some differences in relating factors between patients with single and multiple DWI lesions. These results indicate that time-to-DWI and DWI lesion pattern may be important for the diagnosis and management of TIA.

A Case of Superficial Hemisensory Dysfunction due to Operculo-insular Infarction: Radiological Depiction of Thalamocortical Projections to the Secondary Somatosensory Cortex
A 64-year-old obese man developed hypesthesia in the left arm and leg. Neurological examination revealed decreased senses of pain, touch, and temperature in the left face, arm, trunk, and leg. Remaining functions were normal. Electrocardiogram showed atrial fibrillation. Somatosensory-evoked potentials using the stimulation in the median nerve were normal on both sides. Brain magnetic resonance imaging revealed acute infarction in the right parietal operculum and insula. There were no pathognomonic lesions in the postcentral gyrus, the thalamus, or the brain stem. Cardioembolic operculo-insular infarction was diagnosed. Di...
