Body Mass Index and Stroke: Overweight and Obesity Less Often Associated with Stroke Recurrence
Background: Although obesity is associated with excess mortality and morbidity, mortality is lower in obese than in normal weight stroke patients (the obesity paradox). Studies now indicate that obesity is not associated with increased risk of recurrent stroke in the years after first stroke. We studied the association between body mass index (BMI) and stroke patient's risk of having a history of previous stroke (recurrent stroke).Methods: A registry designed to collect data on all hospitalized stroke patients in Denmark 2000-2010 includes 61,872 acute stroke patients with information on BMI in 38,506. Data include age, se...

Cause-specific Mortality after Stroke: Relation to Age, Sex, Stroke Severity, and Risk Factors in a 10-Year Follow-up Study
We investigated cause-specific mortality in relation to age, sex, stroke severity, and cardiovascular risk factor profile in the Copenhagen Stroke Study cohort with 10 years of follow-up. In a Copenhagen community, all patients admitted to the hospital with stroke during 1992-1993 (n = 988) were registered on admission. Evaluation included stroke severity, computed tomography scan, and a cardiovascular risk profile. Cause of death within 10 years according to death certificate information was classified as stroke, heart/arterial disease, or nonvascular disease. Competing-risks analyses were performed by cause-specific Co...

Stroke Size Correlates with Functional Outcome on the Simplified Modified Rankin Scale Questionnaire
Background: Acute stroke size is one of the factors impacting functional outcome. To further validate the simplified modified Rankin Scale questionnaire (smRSq), we tested its correlation with stroke size.Methods: We screened 60 ischemic stroke patients with acute brain images available for stroke volume measurement who were enrolled in 2 smRSq reliability studies. Inclusion criteria were acute ischemic stroke visible on computed tomography (CT) or magnetic resonance imaging (MRI) and the smRSq scored at least 3 months after stroke. We excluded patients with disabilities from a previous stroke. One investigator who was bli...

Effect of Middle Cerebral Artery Territory Ischemic Stroke on QT Interval
In this study, we investigated whether QT interval dynamics is different in patients with right and left middle cerebral artery (MCA) territory stroke.Method: Electrocardiogram (ECG) intervals were compared between baseline (retrieved retrospectively from medical records) and admission (acquired at the acute hospital admission) in 33 patients (65 ± 9.5 years) with right or left MCA territory ischemic stroke. Head computed tomography (CT), cardiac ultrasound, and cardiac CT scans were undertaken.Results: Stroke was located in the right MCA territory in 21 (64%) and in the left MCA territory in 12 (36%) patients. Patients w...

Wake-up Stroke Within 3 Hours of Symptom Awareness: Imaging and Clinical Features Compared to Standard Recombinant Tissue Plasminogen Activator Treated Stroke
Background: Patients with wake-up stroke (WUS) are excluded from thrombolysis because of unknown time of symptom onset. Previous studies have reported similar stroke severity and early ischemic changes (EICs) in patients with WUS and stroke of known onset. These studies, however, included patients within a large timeframe to imaging or did not quantify EICs. The aim of our study was to quantify EICs of patients with WUS presenting within 3 hours of symptom recognition compared to standard 3-hours recombinant tissue plasminogen activator (rt-PA)–treated patients and assess the extent of ischemic lesion and functional ind...

Hospital Prenotification of Stroke Patients by Emergency Medical Services Improves Stroke Time Targets
Background: Prenotification to hospitals by emergency medical services of patients with suspected stroke is recommended to reduce delays in time-dependent therapies. We hypothesized that hospital prenotification would reduce recommended stroke time targets.Methods: We used the Robert Wood Johnson University Hospital (RWJUH) Brain Attack Database, which includes demographic and clinical data on all emergency department (ED) patients alerted as a Brain Attack between January 1, 2009 and June 30, 2010. Outcome variables included the time from door to stroke team arrival, computed tomographic (CT) scan completion, CT scan inte...

Time to Stroke Magnetic Resonance Imaging
Conclusions: Stroke guidelines favor the use of MRI over CT only during the first 12 hours from symptom onset, yet less than one-third of stroke MRIs are actually performed within this timeframe.

Discrimination of Acute Ischemic Stroke from Nonischemic Vertigo in Patients Presenting with Only Imbalance
We examined 332 consecutive patients with an acute feeling of imbalance who showed no neurologic findings or responsible lesions on CT scan at the hyperacute phase. We examined their clinical backgrounds, physical findings, and laboratory examinations, with ischemic stroke diagnosed by later CT and/or magnetic resonance imaging (MRI). We identified 41 (12.3%) ischemic stroke patients. Atrial fibrillation (odds ratio 4.1; 95% confidence interval 1.4-11.5), white blood cell count (103/μL, 1.4; 1.2-1.6), head and/or neck pain (4.6; 2.1-10.3), first attack of imbalance feeling (3.3; 1.1-12.2), and dizziness (3.7; 1.7-8.3) wer...

The Utility of Middle Cerebral Artery Clot Density and Burden Assessment by Noncontrast Computed Tomography in Acute Ischemic Stroke Patients Treated with Thrombolysis
Conclusions: Utility of the HMCAS as a prognostic marker in stroke thrombolysis is not high in the CT angiography era. Previous observation regarding its positive prognostic role can be attributed to its association with proximal location and extent of clot burden, which are detectable reliably with current CT angiography techniques. Neither quantification nor extent of increased density seems to have clinical utility for treatment decision making in MCA strokes and prediction of emboli composition and response to recanalization attempt.

Pooled Assessment of Computed Tomography Interpretation by Vascular Neurologists in the STRokE DOC Telestroke Network
Conclusions: Both vascular neurologists and reports from spoke radiologists had excellent reliability in identifying radiologic rt-PA contraindications. These pooled findings demonstrate that telestroke evaluation of head CT scans for acute rt-PA assessments is reliable.

Stroke Volume Predicts Nocturnal Hypoxemia in the Acute Ischemic Stroke after Intravenous Thrombolysis
The Goal: The aim of the study was to investigate whether stroke volume or the presence of ischemic stroke lesion on follow-up computed tomography 1 day after admission had association with sleep apnea among ischemic stroke patients undergoing thrombolysis. Materials and Methods: We prospectively recruited 110 consecutive ischemic stroke patients and performed computed tomography on admission and after 24 hours after intravenous thrombolysis. Stroke volume was measured from post-thrombolysis computed tomography scans.

Lateralization of Insular Ischemic Stroke is Not Associated With Any Stroke Clinical Outcomes: The Athens Stroke Registry
Background: Controversial evidence suggests that right insular stroke may be associated with worse outcomes compared to the left insular ischemic lesion. Objectives: We investigated whether lateralization of insular stroke is associated with early and late outcome in terms of in-hospital complications, stroke recurrence, cardiovascular events, and death. Methods: Data were prospectively collected from the Athens Stroke Registry. Insular cortex involvement was identified based on brain CT scans or MRI images.

The Detrimental Effect of Aging on Leptomeningeal Collaterals in Ischemic Stroke
Conclusion: Our findings show that there is a significant interplay between patient age and adequacy of leptomeningeal collateral circulation in patients with proximal MCA occlusion. The relationship could contribute to adverse tissue outcome and thereby to unfavorable clinical outcome observed in elderly patients with ischemic stroke.

Mechanism of Acute Ischemic Stroke in Patients with Severe Middle Cerebral Artery Atherosclerotic Disease
Conclusions: In patients with severe MCA ICAD, the mechanism of stroke is multifactorial, but hemodynamic insufficiency plays a significant role. This finding is important in selecting a subgroup of patients who may benefit from revascularization.
