This retrospective study evaluated left atrial reservoir strain using echocardiography in 79 stroke/TIA patients without prior atrial fibrillation history to identify cardiac sources of emboli. Reduced reservoir strain was associated with cardioembolic stroke mechanisms and atrial fibrillation occurrence, suggesting it may aid in stroke risk stratification and AF detection.
This systematic review and meta-analysis examines the incidence and risk factors for cerebrovascular events (including stroke) in patients with cervical fibromuscular dysplasia, a non-atherosclerotic vascular condition affecting arterial walls. The study synthesizes evidence to characterize stroke risk and associated factors in this patient population.
Researchers developed a surface-enhanced Raman scattering (SERS) detection platform coupled with machine learning algorithms to identify transient ischemic attacks (TIA) through inflammatory markers in serum. The system achieved 99.64% accuracy using LightGBM and demonstrated robust performance across multiple deep learning models (>90% accuracy), with results validated against clinical diagnoses.
This meta-analysis examined ten protein biomarkers across 18,160 acute ischemic stroke (AIS) and 3,410 transient ischemic attack (TIA) patients to identify biomarkers that could improve diagnostic differentiation between these two conditions. Five biomarkers showed statistically significant differences between AIS and TIA groups: S100B, sNfl, copeptin, IL-6, and MMP-9, with MMP-9 demonstrating the largest concentration differential.
This systematic review and meta-analysis of 50 studies demonstrates that head and neck cancer patients receiving radiation therapy have a significantly increased risk of ischemic stroke (8.98 per 1,000 person-years) and carotid stenosis compared to surgical or non-treated populations. The relative risk of stroke is approximately 1.3 times higher in irradiated patients, with carotid stenosis incidence ranging from 0-40% depending on follow-up duration.
