Lei Song, Jun Cheng, Cun Zhang, Hang Zhou, Wenmin Guo, Yu Ye, Rujia Wang, Hui Xiong, Ji Zhang, Ren Ke, Dongfang Tang, Yufei Fu, Zhibing He, Liwei Zou, Longsheng Wang, Lianghong Kuang, Xiaoming Qiu, Tingting Guo, Yongqiang Yu
BACKGROUND: Hematoma expansion (HE) is common in patients with intracerebral hemorrhage (ICH), and associated with a worse outcome. Imaging makers and shorter time from symptom onset are both associated with HE, but prognostic scores based on these parameters individually have not been satisfactory. We hypothesized that a score including both imaging markers of expansion, and time of onset, would improve prediction. METHODS: Patients with supratentorial ICH within 6 h after onset were consecutively recruited from six centers between January 2018 and August 2022...

RATIONALE: Mechanical thrombectomy (MT) associated with the best medical treatment (BMT) has recently shown efficacy for the management of acute ischemic stroke (AIS) secondary to a large vessel occlusion. However, evidence is lacking regarding the benefit of MT for more distal occlusions. AIM: To evaluate the efficacy in terms of good clinical outcome at 3 months of MT associated with the BMT over the BMT alone in AIS related to a distal occlusion. METHODS: The DISCOUNT trial is a multicenter open-label randomized controlled trial involving 22 French University hospitals...

BACKGROUND: Carotid tandem lesions (≥70% stenosis or occlusion) account for 15-20% of acute stroke with large vessel occlusion. AIMS: We investigated the safety and efficacy of intravenous tenecteplase (0.25mg/kg) versus intravenous alteplase (0.9mg/kg) in patients with carotid tandem lesions (TL). METHODS: This is a substudy of the Alteplase compared to Tenecteplase trial. Patients with ≥70% stenosis of the extracranial internal carotid artery (ICA) and concomitant occlusion of the intracranial ICA, M1 or M2 segments of the middle cerebral artery on baseline CTA were included...

BACKGROUND: Patients with minor ischemic stroke or transient ischemic attacks (TIAs) are often treated with dual antiplatelet therapy regimens as part of secondary stroke prevention. Clopidogrel, an antiplatelet used in these regimens, is metabolised into its active form by the CYP2C19 enzyme. Patients with loss of function (LOF) mutations in CYP2C19 are at risk for poorer secondary outcomes when prescribed clopidogrel. AIMS: We aimed to determine the cost effectiveness of three different treatment antiplatelet regimens in ischemic stroke populations with minor strokes or TIAs and how these treatment regimens are influenced by the LOF prevalence in the population...

BACKGROUND: A significant portion of cryptogenic stroke is hypothesized to be secondary to cardiac embolism. However, transthoracic echocardiogram is usually delayed after stroke, and more detailed cardiac imaging is not routinely done. AIMS: This study aimed to determine whether non-ECG-gated cardiac CT angiography (cCTA) during hyperacute stroke would provide diagnostic quality images and act as an adjunct modality of cardiac imaging to detect sources of emboli...

BACKGROUND: India accounts for 13.3% of global disability-adjusted life years (DALYs) lost due to stroke with a relatively younger age of onset compared to the Western population. In India's public healthcare system, many stroke patients seek care at tertiary-level government-funded medical colleges where an optimal level of stroke care is expected. However, there are no studies from India that have assessed the quality of stroke care, including infrastructure, imaging facilities, or the availability of stroke care units in medical colleges...

Remote ischemic conditioning (RIC) is the application of brief periods of ischemia to an organ or tissue with the aim of inducing protection from ischemia in a distant organ. It was first developed as a cardioprotective strategy but has been increasingly investigated as a neuroprotective intervention. The mechanisms by which RIC achieves neuroprotection are incompletely understood. Preclinical studies focus on the hypothesis that RIC can protect the brain from ischemia reperfusion (IR) injury following the restoration of blood flow after occlusion of a large cerebral artery...

RATIONALE: Mechanical thrombectomy (MT), the standard of care for acute ischemic stroke (AIS) secondary to large vessel occlusion (LVO), is generally not offered to patients with large baseline infarct (core). Recent studies demonstrated MT benefit in patients with anterior circulation stroke and large core (i.e. Alberta Stroke Program Early Computed Tomography Score, ASPECTS 3-5). However, its benefit in patients with the largest core (ASPECTS 0-2) remains unproven. AIM: To compare the efficacy and safety of MT plus best medical treatment (BMT) and of BMT alone in patients with ASPECTS 0-5 (baseline computed tomography (CT) or magnetic resonance imaging (MRI)) and anterior circulation LVO within 7 h of last-seen-well...

BACKGROUND: Embolic stroke of undetermined source (ESUS) refers to ischemic stroke where the underlying cause of thromboembolism cannot be found despite the recommended diagnostic workup. Unidentified source of emboli hinders clinical decision-making and patient management with detrimental consequences on long-term prognosis. The rapid development and versatility of magnetic resonance imaging (MRI) make it an appealing addition to the diagnostic routine of patients with ESUS for the assessment of potential vascular and cardiac embolic sources...
