Quantitative CTA vascular calcification, atherosclerosis burden, and stroke mechanism in patients with ischemic stroke
CONCLUSION: Atherosclerosis calcium volumes in major vessels were significantly higher in LAA compared to non-LAA stroke in younger age.PMID:37148773 | DOI:10.1016/j.jns.2023.120667

Stress-induced cardiomyopathy accompanied by heat stroke
We describe a case with high body temperature and coma, who also presented with wide QRS tachycardia and shock. He was initially treated for heat stroke and wide QRS tachycardia. Serial electrocardiographic change and echocardiographic findings suggested this was complicated with stress-induced cardiomyopathy. This case demonstrates the importance of recognizing that serious myocardial damage can result from heat stroke. <Learning objective: Heat stroke can cause multiple organ failure and the presentation of circulatory failure in heat stroke may be the sign of myocardial dysfunction. To distinguish acute coronary ...

Abstract 218: Expanding a Learning Collaborative Model in Chicago to Improve Door to Needle for Stroke Thrombolysis: Raising the Bar Session Title: Poster Session II
Conclusions: Using a learning collaborative model to implement strategies to reduce DTN times among 24 Chicago area hospitals continues to impact times. Regional collaboration, data sharing, and best practice sharing should be a model for rapid and sustainable system-wide quality improvement.

Preventing post-stroke dementia. The MARCH Trial. Protocol and statistical analysis plan of a randomized clinical trial testing the safety and efficacy of Maraviroc in post-stroke cognitive impairment
CONCLUSIONS: The results of this work could lead to a novel, readily available, therapeutic avenue to reduce PSCI, and possibly other pathologies. This study will test safety and effectiveness of Maraviroc in limiting cognitive deterioration and/or post stroke cognitive impairment in patients with cerebral small vessel disease.SCHEDULE: First-patient first-visit was May 2021. Recruitment to complete in 2023, follow-up to complete in 2024.PMID:36082248 | PMC:PMC9446318 | DOI:10.1177/23969873221098857

Reperfusion therapy of acute ischaemic stroke and acute myocardial infarction: similarities and differences
The evolution of reperfusion therapy in acute myocardial infarction and acute ischaemic stroke has many similarities: thrombolysis is superior to placebo, intra-arterial thrombolysis is not superior to intravenous (i.v.), facilitated intervention is of questionable value, and direct mechanical recanalization without thrombolysis is proven (myocardial infarction) or promising (stroke) to be superior to thrombolysis—but only when started with no or minimal delay. However, there are also substantial differences. Direct catheter-based thrombectomy in acute ischaemic stroke is more difficult than primary angioplasty (in S...

A Special Report on Changing Trends in Preventive Stroke/Cardiovascular Risk Assessment Via B-Mode Ultrasonography
AbstractPurpose of ReviewCardiovascular disease (CVD) and stroke risk assessment have been largely based on the success of traditional statistically derived risk calculators such as Pooled Cohort Risk Score or Framingham Risk Score. However, over the last decade, automated computational paradigms such as machine learning (ML) and deep learning (DL) techniques have penetrated into a variety of medical domains including CVD/stroke risk assessment. This review is mainly focused on the changing trends in CVD/stroke risk assessment and its stratification from statistical-based models to ML-based paradigms using non-invasive car...

Heterogeneity in diagnosis and prognosis of ischaemic stroke subtypes: 9-year follow-up of 22000 cases in Chinese adults
CONCLUSIONS: This study highlighted substantial heterogeneity in prognosis of IS subtypes and utility of ML approaches for classification of IS cases with incomplete clinical investigations.PMID:36847304 | DOI:10.1177/17474930231162265

Machine Learning and the Conundrum of Stroke Risk Prediction
Stroke is a leading cause of death and permanent disability worldwide.1 Ischaemic stroke is the most common stroke variety, comprising more than 80% of strokes in the US.2 One mechanism of ischaemic stroke is atherosclerosis in the extracranial and intracranial arteries, with plaque rupture leading to thrombosis. The second major category is embolic stroke, in which thrombi form in the heart or the arterial/venous ...

The association of stroke risk factors with the future thickness of carotid atherosclerotic plaques
DISCUSSION: The effect of each predictor on plaque thickness is complicated by interactions with other risk factors, particularly for the left carotid artery. The side of carotid artery involvement should be considered for stroke prevention.PMID:37125820 | DOI:10.1080/01616412.2023.2208484

A comparative effectiveness study of carotid intervention for long-term stroke prevention in patients with severe asymptomatic stenosis from a large integrated health system
CONCLUSIONS: In this contemporary cohort study of patients with ACS utilizing rigorous analytic methodology, CEA appears to have a small but statistically significant effect on stroke prevention out to 8 years. Further study is needed to appropriately select the subset of patients most likely to benefit from intervention.PMID:37406943 | DOI:10.1016/j.jvs.2023.06.024

Acute ischemic stroke what is hidden behind?
We present a case of a 58-year-old male patient that presented to ED with sudden onset of headache and left-sided hemiparesis, computed tomography (CT) demonstrated an ischemic stroke of the right middle cerebral artery. When the question of whether to start r-TPA or mechanical thrombectomy was discussed, a cardiac point-of-care ultrasound was performed in ED and showed a type A aortic dissection; immediately a CT aortic angiogram was performed and confirmed the diagnosis. The patient was taken to theater and had a favorable outcome. <Learning objective: Acute aortic dissection (AAD) may present as acute ischemic st...

Improving Door-to-needle Times in the Treatment of Acute Ischemic Stroke Across a Canadian Province: Methodology
Background: Alteplase is a proven medical treatment for acute ischemic stroke; however, the effectiveness of this treatment is highly time dependent. Therefore, it is imperative that hospitals treat acute ischemic stroke patients as quickly as possible. The measure, door-to-needle time, is the time from hospital arrival to when alteplase administration begins. Objective: The goal in the Canadian province of Alberta was to reduce the door-to-needle time to a median of 30 minutes and to increase the percent of patients treated within 60 minutes to 90%. Overview of Methodology: A modified version of Institute for Heal...
