Coronary Artery Calcium Score Improves the Prediction of Occult Coronary Artery Stenosis in Ischemic Stroke Patients Stroke
BackgroundCoronary heart disease is a significant cause of morbidity and mortality in stroke patients. The coronary artery calcium score (CACS) has emerged as a robust and noninvasive predictor of coronary events. We assessed the predictive ability of CACS to identify stroke patients with severe (≥50%) occult coronary artery stenosis in a stroke/transient ischemic attack population, in addition to the PRECORIS score, based on Framingham Risk Score and presence of cervicocephalic artery stenosis, which was derived and validated for that purpose.Methods and ResultsWe enrolled consecutive patients aged 45 to 75 years refer...

Intraoperative Completion Studies, Local Anesthesia, and Antiplatelet Medication Are Associated With Lower Risk in Carotid Endarterectomy Clinical Sciences
Conclusions—Local anesthesia, patch plasty compared with primary closure, intraoperative completion studies by duplex ultrasound or angiography, and perioperative antiplatelet medication were independently associated with lower in-hospital stroke or death rates after carotid endarterectomy.

Evaluation and Validation of Prehospital Acute Stroke Scale to Predict Large Vessel Occlusion in Patients with Proven Large Vessel Occlusion- Single Center study in US (P1.274)
Conclusions:The PASS tool is simple, quick, and easy to perform and has high sensitivity in AIS patients with LVO. To assess its value and efficacy in real time it should be implemented into EMS systems and be performed in the pre-hospital setting.Disclosure: Dr. E-Ghanmh has nothing to disclose.

Association between Inflammatory Biomarkers and Progression of Intracranial Large Artery Stenosis after Ischemic Stroke
Conclusions: In addition to traditional risk factors and baseline radiologic findings, circulating levels of IL-6 measured soon after stroke onset are associated with future ILA progression.

Long-Term Follow-up of Incidental Intracranial Aneurysms in Patients with Acute Ischemic Stroke
Conclusions: In our study, the prevalence of incidental aneurysm among acute ischemic stroke patients was 6.1%. After 2 years of follow-up, there was no aneurysm rupture or subarachnoid hemorrhage, and the diameter and shape of aneurysms did not change except for 1 patient in whom the aneurysm disappeared.

Safety of Intravenous Thrombolysis in Acute Ischemic Stroke Patients with Saccular Intracranial Aneurysms
Conclusions: Intravenous thrombolysis was safe among our patients with acute ischemic stroke and incidental intracranial saccular aneurysm.

Refining Angiographic Biomarkers of Revascularization: Improving Outcome Prediction After Intra-arterial Therapy Clinical Sciences
Conclusions— mTICI is superior to TIMI for predicting clinical outcome after intra-arterial therapy. mTICI 2b to 3 is the optimal biomarker for procedural success.

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.

Sensitivity and Specificity of the Hyperdense Artery Sign for Arterial Obstruction in Acute Ischemic Stroke Clinical Sciences
Conclusions— When present in acute ischemic stroke, HAS indicates a high likelihood of arterial obstruction, but its absence indicates only a 50/50 chance of normal arterial patency. Thin-slice CT improves sensitivity of HAS detection. Clinical Trial Registration— URL: http://www.controlled-trials.com/ISRCTN25765518. Unique identifier: ISRCTN25765518.

Distance to Thrombus in Acute Middle Cerebral Artery Occlusion: A Predictor of Outcome After Intravenous Thrombolysis for Acute Ischemic Stroke Clinical Sciences
Conclusion— DT is an independent predictor of clinical outcome in patients with acute MCA occlusion treated with IVT. In acute stroke with MCA occlusion confirmed by CT angiography and DT <16 mm, the likelihood of a good clinical outcome after treatment with IVT was exponentially <50%. This might warrant the evaluation of other therapy forms than IVT in patients with proximal MCA occlusion.

Young-aged stroke in Korea: changing patterns of risk factors and etiologies (P7.120)
CONCLUSIONS: Compared to the previous study, the proportion of male to female ratio decreased. While smoking and drinking rates decreased in male, metabolic risk factors such as diabetes and dyslipidemia increased in both genders, which explain the increasing proportion of large artery atherosclerotic disease in female patients. The proportion of strokes associated with artery dissection increased, which may be due to the use of advanced diagnostic tools. Our data show that etiologies in young age strokes change depending on the changing risk factor profiles and extensiveness of advanced diagnostic work up.Disclosure: Dr. ...
