Description
On Episode 19 of the Stroke Alert Podcast, host Dr. Negar Asdaghi highlights two articles from the August 2022 issue of Stroke: “Direct to Angiosuite Versus Conventional Imaging in Suspected Large Vessel Occlusion” and “Recurrent Ischemic Stroke and Bleeding in Patients With AF Who Suffered an Acute Stroke While on Treatment With NOACs.” She also interviews Dr. Alexander Nave about “Combined Oral Triglyceride and Glucose Tolerance Test After Acute Ischemic Stroke to Predict Recurrent Vascular Events.” Dr. Negar Asdaghi:         Let's start with a few questions. 1) How much time do we actually save if we were to transfer all patients with suspected target vessel occlusion directly to the angiosuite and practically bypassing our current conventional imaging model? 2) What is the impact of an impaired metabolic state as measured by abnormal glucose and triglyceride tolerance tests on the risk of stroke recurrence in patients with ischemic stroke? 3) And finally, should we or should we not change the anticoagulant therapy of a patient with atrial fibrillation who suffered an ischemic stroke despite appropriate treatment with anticoagulation? We have the answers to these questions and much more in today's podcast because this is the best in Stroke. Stay with us. Dr. Negar Asdaghi:         Welcome back to another issue of the Stroke Alert Podcast. My name is Negar Asdaghi. I'm an Associate Professor of Neurology at the University of Miami Miller School of Medicine and your host for the monthly Stroke Alert Podcast. The August 2022 issue of Stroke contains a range of really stimulating articles. We have an interesting study titled "Individual and Joint Effects of Influenza-Like Illness and Vaccinations on Stroke in the Young," led by Dr. Amelia Boehme and colleagues from Columbia University, with its accompanying editorial on how influenza-like illness is associated with increased risk of stroke in the young and middle-aged population while vaccinations of any type is protective of this risk. In a different paper, as part of a population-based study out of Scotland, Dr. Rustam Al-Shahi Salman from University of Edinburgh and colleagues report on a positive association between the use of beta-blockers, especially propranolol, and a lower risk of cerebral cavernous malformation, or CCM, associated intracranial hemorrhage. This study's findings are very interesting and quite important, and I encourage you to review the growing literature to suggest how beta-blockers may, in fact, reduce the risk of CCM-related hemorrhages through their anti-angiogenic properties. Dr. Negar Asdaghi:         Later in the podcast, I have the great pleasure of interviewing Dr. Alexander Nave from Charité University Hospital in Berlin to discuss the relationship between having an impaired metabolic state in the setting of acute stroke and the risk of ischemic stroke recurrence, as we'll review the long-awaited results of the Berlin "Cream&Sugar" study, a very catchy title. But first, with these two articles. Dr. Negar Asdaghi:         Time to successful endovascular reperfusion is an important predictor of clinical outcomes in patients with acute ischemic stroke related to a large vessel occlusion. And for years, we've known that the faster we're able to open the affected artery, the better the ischemic stroke outcomes are. Correspondingly, systems of care have adapted to various requirements of this so-called rapid workflow to ensure that all necessary pre-reperfusion steps are completed as fast as possible, preferably most in parallel to one another. And if any steps are unnecessary, they're bypassed altogether. Dr. Negar Asdaghi:         Despite all these modifications to date, time from conventional imaging to angiosuite arrival remains both the longest and the most variable interval in the intra-hospital workflow prior to endovascular therapy. So, it's not surprising that many recent studi
