Pulmonary Embolism in Ischemic Stroke: Clinical Presentation, Risk Factors, and Outcome Stroke
Conclusions In this large cohort study, PE occurred in nearly 1% of AIS patients. PE was more common in patients with severe stroke, history of cancer, previous DVT/PE or acute DVT and associated with lower short- and long-term survival, greater disability, and longer length of stay.

Improving Door-to-Needle Times for Acute Ischemic Stroke: Effect of Rapid Patient Registration, Moving Directly to Computed Tomography, and Giving Alteplase at the Computed Tomography Scanner Original Articles
Conclusions— Taking the patient to CT on the emergency medical services stretcher, registering the patient as unknown, STAT stroke protocol, and administering alteplase in CT are associated with lower DTN time.

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...

Fragmentation of Care and the Use of Head Computed Tomography in Patients With Ischemic Stroke Original Articles
Conclusions— Rates of high-intensity CT use for patients with ischemic stroke reflect wide practice patterns across regions and races. Medicare expenditures parallel these disparities. Fragmentation of care is associated with high-intensity CT use.

Prevalence and Prognostic Features of ECG Abnormalities in Acute Stroke
Conclusions About 4 in 5 acute stroke patients in this African cohort had evidence of a baseline ECG abnormality, but presence of any atrial enlargement was the only independent ECG predictor of death or disability.

Vertebrobasilar Artery Calcification as a Risk Factor for the Development of Stroke: Case-Control Study From a Tertiary Care Center, Southern India
Conclusion The presence of higher grades of calcifications in the vertebrobasilar arteries is a major risk factor for stroke. Hence, its presence in asymptomatic individuals needs to be taken as a warning sign for the development of stroke.PMID:37605701 | PMC:PMC10440145 | DOI:10.7759/cureus.42196

Relationship between left atrial appendage morphology and stroke in patients with atrial fibrillation
Background: Atrial fibrillation (AF) is an important cause of stroke. Given the morbidity and mortality associated with stroke, the risk stratification of patients based on left atrial appendage (LAA) characteristics is of great interest.Objective: To explore the association between LAA morphology and LAA characteristics including the extent of trabeculations, orifice diameter, and length with prevalent stroke in a large cohort of patients with drug refractory AF who underwent AF ablation to develop mechanistic insight regarding the risk of stroke.Methods: An institutional cohort of 1063 patients referred for AF ablation f...

Association between vertebrobasilar artery geometry and vertebrobasilar stenosis, recurrence, and death in posterior circulation stroke and transient ischemic attack
CONCLUSIONS: The geometric characteristics of the VBA are associated with vertebrobasilar stenosis, LAA stroke, 1-year recurrence, and death in posterior circulation stroke and TIA. VBA geometry may be used to stratify the risk of stroke and TIA in the posterior circulation.PMID:37598548 | DOI:10.1016/j.jstrokecerebrovasdis.2023.107306

Thoracic Aortic < sup > 18 < /sup > F-Sodium Fluoride Activity and Ischemic Stroke in Patients With Established Cardiovascular Disease
CONCLUSIONS: In patients with established cardiovascular disease, thoracic aortic 18F-sodium fluoride activity is associated with the progression of atherosclerosis and future ischemic stroke. Arterial 18F-sodium fluoride activity identifies localized areas of atherosclerotic disease activity that are directly linked to disease progression and downstream regional clinical atherothrombotic events.

Association of Left Atrial Sphericity with Risk of Stroke in Patients with Atrial Fibrillation. Sub-Analysis of the ASSAM Study
ConclusionLASP is associated with prior stroke in AF patients. The proposed new formula for identification of AF patients who are at risk of stroke, based on geometrical measurements of LA, is superior to the basic LASP in identification of AF patients with a history of stroke.
