View clinical trials related to Carotid Artery Plaque.
Filter by:A study on the prediction model of carotid unstable plaque protein and its early intervention. Protein antibody chip was used to detect the remaining biological samples, and patients with carotid artery unstable plaque with stroke risk were selected for interventional clinical trials. The selected patients were randomly divided into 3 groups, which were treated with Zhu's Wenban Formula (TCM compound granules), Qushi Formula (TCM compound granules) and placebo for 6 months, respectively. The size and number of carotid artery unstable plaques before and after 6 months were observed, and the occurrence of adverse reactions during the intervention period was observed.
Objective: To explore the association between spatio-temporal blood flow velocities (peak systole and end-diastole at prior-stenosis, at maximum stenosis, and post-stenosis) and carotid plaque vulnerability defined by histology staining. Secondary, to assess the association between ultrasound elastography and carotid plaque vulnerability defined by histology staining. Furthermore, to assess the association between blood flow-derived parameters, including wall shear stress (WSS), vector complexity and vorticity, and plaque vulnerability. To evaluate the hemodynamic consequences of a CEA. Last, to explore whether the presence of circulating biomarkers is related to the degree of plaque vulnerability (as reflected by histology and/or ultrasound). Study design: A multicentre, prospective, observational, cohort study in a total of 70 patients. Study population: Patients with a carotid artery stenosis ≥50% according to clinically performed imaging (i.e. duplex, computed tomography angiography (CTA), or magnetic resonance angiography (MRA)) that are scheduled for a CEA. Intervention (observational): A carotid ultrasound with flow and elastography (strain and shear wave) measurements will be performed maximally 2 weeks prior to the CEA. In the first 20 included patients in the Radboudumc, a 10 mL blood sample will be collected during surgery via the arterial line that is applied for regular care. The plaque excised during CEA will be histologically examined to assess the plaque composition, and therefore plaque vulnerability. Ultrasound-based flow imaging will be repeated six weeks after the CEA to assess the hemodynamic consequences of the CEA procedure. Besides, clinical parameters will be subtracted from electronic health record or, if missing, anamnestically collected from the patient. Main study parameters/endpoints: Association between 2D spatio-temporal blood flow velocities (peak systole and end-diastole at prior-stenosis, maximum stenosis and post-stenosis), measured by ultrafast ultrasound measurements, and plaque vulnerability (stable versus unstable), defined by histology staining.
The investigators want treat Vulnerable plaque of carotid artery with a herbal and insects Chinese medicine. Designing a RCT trial to prove the effect and safety.
