Article Abstract

We assessed cost-effectiveness of insertable cardiac monitors (ICMs) in a US cryptogenic stroke population. We modelled lifetime costs and quality-adjusted life years for three monitoring strategies post cryptogenic stroke: ICM starting immediately, ICM starting after Holter monitoring (delayed ICM) and standard of care involving intermittent ECG and Holter monitoring. Patient characteristics and detection efficacy were based on the CRYSTAL-AF trial. AF detection altered the modelled anticoagulation therapy and subsequent stroke and bleed risks. Immediate ICM was found to be cost-effective versus standard of care and cost-saving versus delayed ICM. Results were robust to sensitivity analyses. ICMs are a cost-effective diagnostic tool for the prevention of recurrent stroke in a US cryptogenic stroke population.

Background: Patent foramen ovale (PFO) has been identified as a potential risk factor for cryptogenic stroke (CS). Although transesophageal echocardiography (TEE) is considered the gold standard for PFO detection, false-negative results remain a clinical concern, particularly in CS patients with high suspicion of PFO-related etiology.

Aims: To evaluate the clinical utility of transcatheter PFO exploration (TPFOE) in CS patients with negative TEE findings but high suspicion of PFO-related etiology.

Background: protamine sulfate is used to reduce bleeding risk after Carotid Artery Stenting (CAS), but its efficacy in personalized patient settings remains underexplored. This study aims to identify factors associated with greater benefits from protamine sulfate following CAS.

Methods: A retrospective review of Vascular Quality Initiative (VQI) data (2016-2022) identified patients undergoing CAS, divided into Transfemoral CAS (TF-CAS) and Transcarotid artery revascularization (TCAR) groups.

Endovascular therapy (EVT) is standard care for acute ischemic stroke due to large vessel occlusion, but its availability is limited in areas with long distances. It has also been demonstrated that there are differences in the utilization of thrombectomy related to socioeconomic factors. The aim of this study is to examine regional differences in the utilization of mechanical thrombectomy and outcome within one comprehensive stroke center district in terms of distance and income.

20(R)-ginsenoside Rg3 Inhibits Neuroinflammation Induced by Cerebral Ischemia/Reperfusion Injury by Regulating the Toll-Like Receptor 4/Myeloid Differentiation Factor-88/Nuclear Factor Kappa B Signaling Pathway.

20(R)-ginsenoside Rg3 can reduce the effects of oxidative stress and cell death in cerebral ischemia‒reperfusion injury (CIRI). Neuroinflammation is crucial post-CIRI, but how 20(R)-Rg3 affects ischemia‒reperfusion-induced neuroinflammation is unclear. To study 20(R)-Rg3's effects on neuroinflammation and neuronal preservation in stroke models and explore toll-like receptor 4/myeloid differentiation factor-88/nuclear factor kappa B (TLR4/MyD88/NF-κB) pathway mechanisms.
