Filter by:Until recently, acute ischemic stroke (AIS) patients with a baseline large infarct core have been generally excluded from clinical trials of endovascular therapy (EVT). A first multicenter randomized trial (Rescue Japan Limit trial) found a significant benefit of EVT in AIS patients with large infarct core (DWI-ASPECTS of 3-5). Another non-randomized multicenter prospective study found a positive association of EVT with 3-month outcome in AIS patients with a baseline CTP ischemic core volume >70mL. More recently, 2 additional randomized trials were published. They both confirmed a strong efficacy of EVT in patients with large infarct core. However, even with EVT, the proportion of good outcome (3-month mRS score of 0-3), remains low in these highly severe AIS patients ranging from 8-30%. Almost 75% of EVT-treated patients are still severely disabled or dead at 3 months. In experimental studies, we and others described the pathophysiological features of the downstream microvascular thrombosis (DMT) in AIS setting highlighting its immediate occurrence and the pivotal role of platelet activation and aggregation. In recent clinical studies, it has been shown that, even with a complete angiographic recanalization after EVT, up to 40% of patients presented no-reflow (NR), a failure of downstream microvascular reperfusion, visible on perfusion imaging performed after EVT. Some clinical studies reported the clinical impact of NR after successful EVT. We found that DMT participated to the development of neurovascular lesions in AIS with both an early ischemic lesion growth risk evolving towards a delayed hemorrhagic transformation (HT) and vasogenic edema risks and therefore worse outcome. Our results suggested that an antiplatelet therapy infused early in AIS patients could reduce both the ischemic lesion but also the risk of delayed vasogenic edema and HT. Platelet glycoprotein VI (GPVI) is a key receptor for collagen and fibrin and plays a major role in platelet activation, platelet recruitment and thrombosis. Furthermore, inhibition of the GPVI does not impair haemostasis and subjects with a genetic or acquired GPVI deficiency are not prone to excessively bleed. Glenzocimab is a monoclonal antibody directed against the GPVI. It has been developed as an immediate antiplatelet agent with minimal bleeding risk for treating AIS. The ACTIMIS trial, a phase IB/IIA clinical study that assessed for the first time the glenzocimab IV infusion in AIS patients found very promising safety data including a significant reduce of symptomatic HT (1% vs. 7.8%) and mortality rates (7.8% vs. 18.7%), especially in severe AIS patients. Our hypothesis is that IV glenzocimab infusion would improve good functional outcome in large ischemic core AIS patients treated with EVT by reducing the DMT, ischemic lesion growth, and the HT rate.
The objective of this clinical trial was to explore the efficacy and safety of Y-3 injection at different doses in patients with acute ischemic stroke within 48 hours of onset. A multicenter, randomized, double-blind, parallel, placebo-controlled trial design was designed to include 240 participants. Subjects press 1:1:1: 1 ratio of patients were randomly divided into Y-3 low-dose group (20 mg/ time, qd), medium-dose group (40 mg/ time, qd), high-dose group (60mg/ time, qd) and placebo control group, with 60 cases in each group. Random stratification factors include: Time of onset (≤24 hours, > 24 hours). The patients were treated for 10 consecutive days (10 times) and followed up to 90 days after the first dose. The trial was divided into three phases: screening/baseline, treatment, and follow-up. Screening/baseline period: Subjects enter the screening/baseline period for screening examination after signing the informed consent. Treatment period: Eligible subjects were randomly assigned at a ratio of 1:1:1:1 to receive Y-3 injection low-dose group, medium-dose group, high-dose group and placebo control drug for 10 consecutive days (10 times), during which relevant examinations required by the protocol were conducted and safety was assessed. Follow-up period: Participants who finished treatment were followed up until 90 days after the first dose. Stroke-related scale scores were performed at 10, 30, and 90 days after first use of the investigational drug The scores of Montgomery Depression Rating Scale (MSAS) and Hamilton Anxiety Scale (HAMA) were performed on the 10th and 90th days after the use of experimental drugs. Adverse events were recorded during treatment and follow-up to further assess safety
Acute mesenteric ischaemia (AMI) is a notorious disease with a high mortality, the diagnostic and management is truly multidisciplinary, but not very extended. The aim of this study is to analyse the results of the patients admited with an AMI in Catalonia.
Ischemic stroke continues to be of the leading causes of disability and death. Distal vessel occlusion one of most presenting and disabling varieties of ischemic stroke. Distal vessel occlusion stroke is a type of ischemic stroke that affects the small arteries in the brain, usually beyond the M2 segment of the middle cerebral artery. These strokes can cause various neurological symptoms depending on the location and size of the occluded vessel and the extent of the brain tissue damage
The results of previous studies were used to assess the causal association between TK levels and stroke occurrence at 5 and 12 years of follow-up, respectively.
1.1. Background Cardiovascular disease (CVD) remains the leading cause of death in our country for over four decades. The pathophysiology of CVD begins with various cardiovascular risk factors (CRFs) and their poor management, leading to subclinical lesions in target organs such as albuminuria or left ventricular hypertrophy, which may evolve into CVD. This progression is referred to as the cardiovascular continuum. Patients with chronic cardiovascular conditions require comprehensive periodic health monitoring in primary care (PC), including lifestyle advice and an assessment of comorbidities. Risk factors linked to disease progression are monitored and managed, along with medication reconciliation and planning follow-up care. Such activities, especially post-COVID, help maintain clinical stability and organize healthcare demand, reducing unnecessary interventions and costs. In Galicia, continuity of care programs for ischemic heart disease focus on optimizing service delivery at appropriate levels, including electronic consultations that improve healthcare accessibility, outcomes, and cost-effectiveness. Introducing Inclisiran for chronic CVD patients post-acute coronary syndrome (ACS) hospitalization might streamline care continuity, reducing healthcare costs and improving outcomes. 1.2. Purpose The disruption of care continuity in patients post-ACS increases their risk of mortality and hospitalizations due to coronary complications and comorbidities, as well as emergency visits and unplanned healthcare interactions, thus elevating healthcare costs. We propose reorganizing care continuity for ACS patients by establishing a PC pathway with scheduled semi-annual visits to assess overall and cardiovascular health and to evaluate patient prognosis and healthcare resource utilization. 2. Objectives 2.1. Primary Objectives The main goal is to evaluate whether a follow-up program incorporating Inclisiran treatment in patients with chronic coronary syndrome can optimize follow-up (reducing unscheduled visits to PC and hospital emergency departments), improve control of risk factors (like physical activity, adherence to a Mediterranean diet, lipid profiles, blood pressure, glycemic profile, and renal function), and decrease direct economic costs. 2.2. Secondary Objectives The secondary objectives include analyzing adherence to prescribed chronic pharmacological treatment, factors driving higher demand among patients with chronic coronary syndrome, reasons for emergency visits, hospital admissions, and causes of mortality among these patients. 3. Methodology 3.1. Study Design A pilot, multicentric, analytical intervention study will be conducted involving five health centers in the Santiago de Compostela health area, with specific inclusion and exclusion criteria outlined. The study will monitor patients over 27 months, following a detailed protocol.
CAIS-MT is a single-center, prospective cohort study, to evaluate the correlation between outcomes of endovascular treatment(EVT) and intracranial artery calcification(IAC) in patients with acute ischemic stroke due to large or medium vessel occlusion.
The SupPORT Registry aims at collecting real-world from Portuguese centers performing femoral-popliteal revascularization with Supera (r) implants. This is a prospective non-randomized non-controlled consecutive registry.
The goal of this clinical trial is to learn if transcranial magnetic stimulation(rTMS) can improve neurological rehabilitation in patients with acute ischemic stroke. The main questions it aims to answer are: Can rTMS Promote Recovery of Limb Impairment in Patients with Acute Ischemia? Can rTMS Cause Changes in the Functional Connections of Brain Networks in Patients? Researchers will compare rTMS therapy to non-stimulation therapy to see if rTMS is effective in promoting neurological recovery from ischemic stroke. Participants will: Receive rTMS or sham stimulation with LF-rTMS on the contralateral M1 of the brain lesion for 20 minutes, 1200 pulses, 120% RMT, and a treatment period of 5 days； Be evaluated on a scale before and after treatment
The trial is a multicenter, prospective, open-label, blinded-endpoint randomized controlled design. Participants with acute minor ischemic stroke (baseline NIHSS≤5) accompanied with measurable neurological deficit will be randomized 1:1 to 0.25mg/kg intravenous tenecteplase or standard medical treatment.
