NCT06315153

Brief Summary

This observational study was designed for the assessment of plaque vulnerability in patients with carotid atherosclerotic stenosis and the development of predictive models for the occurrence and recurrence of atherosclerotic ischemic stroke. The objectives of the study were as follows: first, to integrate the degree of carotid stenosis and plaque characteristics assessed by vascular ultrasound for a comprehensive assessment of plaque vulnerability; second, to develop an assessment tool for the risk of future ischemic stroke in patients with asymptomatic carotid stenosis by combining vascular risk factors, serologic markers, carotid ultrasound characteristics, and contrast-enhanced ultrasonographic parameters; and third, to incorporate vascular ultrasound parameters into existing predictive models of ischemic stroke recurrence risk to develop a risk assessment tool for atherosclerotic ischemic stroke. The main questions it aims to answer are:

  • How to screen high-risk patients and those eligible for revascularization from asymptomatic carotid stenosis patients for primary prevention of stroke.
  • How to improve the prediction accuracy of atherosclerotic ischemic stroke based on existing prediction models for secondary prevention of stroke.

Outcome Measures

Primary Outcomes (2)

  • The occurrence of ischemic stroke

    Clinical symptoms related to neurological deficits in patients and/or discovery of new infarcted lesions on head magnetic resonance imaging/computed tomography scans

    2 years

  • The recurrence of ischemic stroke

    Clinical symptoms related to neurological deficits in patients and/or discovery of new infarcted lesions on head magnetic resonance imaging/computed tomography scans

    2 years

Study Arms (2)

symptomatic group

An ischemic stroke was defined as occurring if the patient developed clinical symptoms related to neurological deficits and/or new infarcted lesions were detected on magnetic resonance imaging, and patients who developed ischemic strokes were classified in the symptomatic group.

asymptomatic group

Patients without an ischemic stroke were classified in the asymptomatic group.

Eligibility Criteria

Age40 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Five hundred hospitalized patients with ≥50% carotid artery stenosis between January 2022 and January 2024 were collected, including 400 in Xuanwu Hospital of Capital Medical University and 100 in the First Hospital of Jilin University.

You may qualify if:

  • ① Patients aged ≥ 40 years old; ② Complete clinical data and serological indicators; ③ Carotid artery ultrasound examination was performed after admission.

You may not qualify if:

  • ① Unilateral or bilateral carotid artery occlusion; ②Carotid stenosis caused by other reasons, such as entrapment, aortitis, radiculopathy and muscle fiber dysplasia; ③Previous carotid stenting or carotid endarterectomy; ④Carotid artery plaques are strongly echogenic with acoustic shadowing, resulting in unclear detection of the lumen.
