- * Results indicated that patients using NOACs had a significantly lower risk of ischemic stroke, systemic embolism, major bleeding, and death compared to those on warfarin, particularly among those taking standard doses of NOACs.
- * The findings conclude that NOACs are more beneficial than warfarin in reducing the risk of secondary complications related to ischemic strokes in this patient population, whereas low
Article Abstract
Previous studies have rarely investigated the role of non-vitamin K oral anticoagulants (NOAC) and warfarin in the secondary prevention of ischemic stroke patients with nonvalvular atrial fibrillation (NVAF). In this study, we compared the effectiveness and safety of NOAC and warfarin for secondary prevention in Korean ischemic stroke patients with NVAF. Based on the Korean National Health Insurance Service Database, this study included 21,064 oral anticoagulants-naïve acute ischemic stroke patients with NVAF between July 2015 and June 2019. The main study outcomes included ischemic stroke, systemic embolism, major bleeding, and death. During the observational periods, NOAC users had a significantly decreased risk of ischemic stroke + systemic embolism (adjusted hazard ratio [aHR] 0.86; 95% confidence interval [CI] 0.78-0.95), ischemic stroke (aHR 0.89; 95% CI 0.81-0.99), major bleeding (aHR 0.78; 95% CI 0.68-0.89), and all-cause death (aHR 0.87; 95% CI 0.81-0.93). Standard-dose NOAC users had a lower risk of ischemic stroke, systemic embolism, and major bleeding events than warfarin users. In contrast, low-dose NOAC users did not differ in risk from warfarin users for all outcomes. In conclusion, NOACs were associated with a lower risk of secondary thromboembolic events and bleeding complications in Korean ischemic stroke patients with NVAF than warfarin.

Intravenous thrombolysis (IVT) and endovascular therapy (EVT) are the cornerstones of acute ischemic stroke treatment. While IVT has been an integral part of acute therapy since the mid-1990s, EVT has evolved as one of the most effective treatments in medicine over the past decade. Traditionally, systemic thrombolysis has been performed with alteplase (rtPA).

Objective: To evaluate the relationship between infarct pattern, inferred stroke mechanism and risk of recurrence in patients with ischaemic stroke. The question is clinically relevant to optimise secondary stroke prevention investigations and treatment.
Design: We conducted a retrospective analysis of the dabigatran treatment of acute stroke II (DATAS II) trial (ClinicalTrials.

Objective: The leptomeningeal ivy sign is a distinctive finding of moyamoya disease (MMD), characterized by a linear high signal intensity along the cortical sulci on contrast-enhanced T1 magnetic resonance imaging (MRI) and fluid-attenuated inversion-recovery MRI. We recently identified a similar linear enhancement along the cortical sulci using gadolinium-enhanced vessel wall MRI (VWMR) in patients with MMD. The aim of this study was to introduce the concept of the "VWMR ivy sign (VIS)".

Acute ischemic stroke (AIS) is a dangerous neurological disease associated with an imbalance in Th17/Treg cells and abnormal activation of the Wnt/β-catenin signaling pathway. This study aims to investigate whether inhibition of miR-155 can activate the Wnt/β-catenin signaling pathway to improve Th17/Treg imbalance and provide neuroprotective effects against stroke. We employed a multi-level experimental design.

Background And Purpose: Leptomeningeal collaterals have been associated with better outcomes in large-vessel stroke, but little is known about how the Circle of Willis (CoW) collaterals affect stroke outcomes. We aimed to determine the relationship between three anatomically distinct CoW subtypes and 90-day outcomes in acute ischemic stroke patients after successful revascularization via endovascular thrombectomy (EVT).
Materials And Methods: We performed a retrospective analysis of patients treated with successful EVT for large-vessel occlusion at a comprehensive stroke center between May 2016 and November 2023.
