Clinical Utility of Electronic Alberta Stroke Program Early Computed Tomography Score Software in the ENCHANTED Trial Database Clinical Sciences
Background and Purpose—Clinical utility of electronic Alberta Stroke Program Early CT Score (e-ASPECTS), an automated system for quantifying signs of infarction, was evaluated in a large database of thrombolyzed patients with acute ischemic stroke.Methods—All baseline noncontrast computed tomographic scans of patients with anterior circulation acute ischemic stroke who participated in the alteplase dose arm of the randomized controlled trial ENCHANTED (Enhanced Control of Hypertension and Thrombolysis Stroke Study) were reviewed; poor quality and large (>6 mm) slice thickness were excluded. Included scans had e-ASPECTS...

Protocol for the perfusion and angiography imaging sub‐study of the Third International Stroke Trial (IST‐3) of alteplase treatment within six‐hours of acute ischemic stroke
RationaleIntravenous thrombolysis with recombinant tissue Plasminogen Activator improves outcomes in patients treated early after stroke but at the risk of causing intracranial hemorrhage. Restricting recombinant tissue Plasminogen Activator use to patients with evidence of still salvageable tissue, or with definite arterial occlusion, might help reduce risk, increase benefit and identify patients for treatment at late time windows. AimsTo determine if perfusion or angiographic imaging with computed tomography or magnetic resonance help identify patients who are more likely to benefit from recombinant tissue Plasminogen Ac...

Intra-Arterial Therapy and Post-Treatment Infarct Volumes: Insights From the ESCAPE Randomized Controlled Trial Clinical Sciences
Conclusions— These results support the primary results of the ESCAPE trial and show that the biological underpinning of the success of endovascular therapy is a reduction in infarct volume. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT01778335.

Stroke Care: A Balanced Approach to the tPA Debate
In conclusion, alteplase is the only treatment available for acute ischemic stroke that is effective in some patients. In order to improve tPA effectiveness and minimize risks, patients with symptoms suggestive of an AIS should get rapid assessment and treatment with tPA after careful review of the contraindications. Given that smaller strokes can still be associated with considerable long term neurological morbidity, treatment should still be considered in those patients after weighing the risks and benefits and in consultation with the patient and family. Advanced age should also not be a limiting factor. Although the NI...

Frequency of Hemorrhage on Follow Up Imaging in Stroke Patients Treated With rt-PA Depending on Clinical Course
Conclusions: Frequency of hemorrhagic transformation in Routine follow-up brain imaging and consecutive changes in therapeutic management were different depending on clinical course measured by NHISS score. Introduction Brain imaging 24–36 h after systemic thrombolysis for acute ischemic stroke is recommended in American Stroke Association and European Stroke Organization guidelines (1, 2). Brain imaging is performed to detect secondary bleeding or hemorrhagic transformation in order to adapt medical stroke prevention if necessary. Guideline recommendations are based on the results of the first study on rt-PA...

Influence of Sex on Stroke Prognosis: A Demographic, Clinical, and Molecular Analysis
Conclusion Our data suggest that women who suffer from IS present with a poorer functional outcome than men at 3-months, regardless of other preclinical and clinical factors during the acute phase. These relationships seem to be mediated by atrial dysfunction and inflammation. The inflammatory response is slightly higher in women; however, there are no sex differences in their functional behavior. There is a probable relationship between the molecular marker of atrial dysfunction NT-proBNP and worse functional outcome in women, and the connection seems to be more important in cardioembolic stroke patients. In patients wi...

Memphis Mobile Stroke Unit Saves Lives
A year after a mobile stroke unit hit the streets of Memphis, officials say it is saving lives by cutting the time it takes to treat stroke patients. The University of Tennessee Health Science Center began using the 14-ton ambulance last year as part of a three-year controlled study. The unit has a CT scanner that can X-ray images of the brain, and is equipped to provide early fluids to stroke patients and dye blood vessels to determine the type of stroke the patient has had. "The emergency room on average takes 40 to 50 minutes to do the things we do in 13 to 14 minutes," said Dr.Andrei Alexandrov, UTHSC neurolo...

Tenecteplase versus Alteplase for Stroke Thrombolysis Evaluation Trial in the Ambulance (Mobile Stroke Unit--TASTE-A): protocol for a prospective randomised, open-label, blinded endpoint, phase II superiority trial of tenecteplase versus alteplase for ischaemic stroke patients presenting within 4.5 hours of symptom onset to the mobile stroke unit
Introduction Mobile stroke units (MSUs) equipped with a CT scanner are increasingly being used to assess and treat stroke patients’ prehospital with thrombolysis and transfer them to the most appropriate hospital for ongoing stroke care and thrombectomy when indicated. The effect of MSUs in both reducing the time to reperfusion treatment and improving patient outcomes is now established. There is now an opportunity to improve the efficacy of treatment provided by the MSU. Tenecteplase is a potent plasminogen activator, which may have benefits over the standard of care stroke lytic alteplase. Specifically, in the MSU ...

Routine serum C‐reactive protein and stroke outcome after intravenous thrombolysis
ConclusionsAccording to our findings, elevated routine serum CRP measured within 24 h after admission does not seem to independently affect the outcome in patients receiving intravenous thrombolysis for stroke. However, further studies of blood samples taken directly before the treatment are needed.

Endovascular clot retrieval for acute ischaemic stroke: the Auckland City Hospital experience.
CONCLUSIONS: Endovascular clot retrieval can be safely and effectively performed in a New Zealand setting with similar results to recent trials in anterior circulation occlusion patients. We suggest that District Health Boards develop clot retrieval services as part of regional hyperacute stroke treatment pathways. PMID: 26645756 [PubMed - in process]

Effect of alteplase on the CT hyperdense artery sign and outcome after ischemic stroke
Conclusions: IV alteplase promotes measurable reduction in HAS regardless of HAS location or extent. Alteplase increased independence at 6 months in patients with and without HAS. Classification of evidence: This study provides Class I evidence that for patients within 6 hours of ischemic stroke with a CT hyperdense artery sign, IV alteplase reduced intra-arterial hyperdense thrombus.
