Incremental predictive value of carotid arterial strain in patients with stroke
AbstractAlthough increased carotid intima-media thickness (IMT) is a well-known risk factor for stroke, carotid IMT alone is not sufficient for risk stratification. The assessment of arterial properties using velocity vector imaging (VVI) represents a new method for quantifying structural changes. We sought to investigate the characteristics and the clinical value of carotid arterial mechanics using VVI in patients with stroke. Fifty male patients (55  ± 5 years) with stroke, 30 healthy age-matched volunteers (54 ± 8 years), and 30 healthy young male volunteers (29 ± 5 years) were evaluated. The peak circ...

Clinical and imaging features associated with intracranial internal carotid artery calcifications in patients with ischemic stroke
Conclusion ICAC burden reflects a continuum of atherosclerotic disease involving carotid arteries together with other craniocervical vascular beds. ICAC is significantly associated with stroke of large vessel or cardioembolic origin. This information might help the clinician in prioritizing etiologic work-up in the acute period.

Assessment of Intracranial Collaterals on CT Angiography in Anterior Circulation Acute Ischemic Stroke FELLOWS' JOURNAL CLUB
CONCLUSIONS: Only the Miteff scoring system for intracranial collaterals is reliable for predicting favorable outcome in thrombolyzed acute anterior circulation ischemic stroke. However, poor outcomes can be predicted by most of the existing methods of scoring intracranial collaterals.

Ischemic Stroke: Measurement of Intracranial Artery Calcifications Can Improve Prediction of Asymptomatic Coronary Artery Disease Neuroradiology
Conclusion: The IAC scores quantified by using unenhanced CT correlate significantly with coronary calcium scores and may serve as an independent predictor of asymptomatic CAD in patients with ischemic stroke. © RSNA, 2013

Middle Cerebral Artery Stenosis in Patients with Acute Ischemic Stroke and TIA in Israel BRAIN
CONCLUSIONS: An independent and significant correlation was found between MCA stenosis and vascular risk factors (diabetes mellitus) and vascular diseases, thus emphasizing the similarity of intracranial MCA stenosis and other vascular diseases originating from atherosclerosis. There was no influence of ethnicity on intracranial stenosis in our population.

Contrast-induced nephropathy: A dilemma between loss of neurons or nephrons in the setting of endovascular treatment of acute ischemic stroke.
CONCLUSION: Contrast-induced nephropathy is a relatively common complication after endovascular treatment of acute ischemic stroke and is associated with worse outcome in patients with this condition. However, there is no increase in the frequency of hemodialysis after the use of iodinated contrast medium. PMID: 31645156 [PubMed - as supplied by publisher]

Visualization of Lenticulostriate Arteries by Flow-Sensitive Black-Blood MR Angiography on a 1.5T MRI System: A Comparative Study between Subjects with and without Stroke BRAIN
CONCLUSIONS: Using FSBB-MRA to visualize LSA branches, we found a significant reduction in the numbers of LSA branches in patients with stroke, and hypertension was inversely related to total LSA length. FSBB is a promising method to investigate the LSA by using 1.5T MR imaging.

The Effect of Dabigatran Plasma Concentrations and Patient Characteristics on the Frequency of Ischemic Stroke and Major Bleeding in Atrial Fibrillation Patients The RE-LY Trial (Randomized Evaluation of Long-Term Anticoagulation Therapy)
ObjectivesThe goal of this study was to analyze the impact of dabigatran plasma concentrations, patient demographics, and aspirin (ASA) use on frequencies of ischemic strokes/systemic emboli and major bleeds in atrial fibrillation patients.BackgroundThe efficacy and safety of dabigatran etexilate were demonstrated in the RE-LY (Randomized Evaluation of Long-Term Anticoagulation Therapy) trial, but a therapeutic concentration range has not been defined.MethodsIn a pre-specified analysis of RE-LY, plasma concentrations of dabigatran were determined in patients treated with dabigatran etexilate 110 mg twice daily (bid) or 150...

Middle Cerebral Artery Pulsatility Index is Associated with Cognitive Impairment in Lacunar Stroke
CONCLUSIONSPI was associated with the cognitive performance in patients with lacunar infarcts and a lacunar syndrome. An elevated PI may be related to impairment in several cognitive domains. These findings suggest that transcranial Doppler ultrasonography could be an adjunct tool for early diagnosis of cognitive impairment after stroke.

Impaired Retinal Vasoreactivity: An Early Marker of Stroke Risk in Diabetes
ABSTRACT Diabetes is a common cause of small vessel disease leading to stroke and vascular dementia. While the function and structure of large cerebral vessels can be easily studied, the brain's microvasculature remains difficult to assess. Previous studies have demonstrated that structural changes in the retinal vessel architecture predict stroke risk, but these changes occur at late disease stages. Our goal was to examine whether retinal vascular status can predict cerebral small vessel dysfunction during early stages of diabetes. Retinal vasoreactivity and cerebral vascular function were measured in 78 subjects (19 heal...
