NCT04928547

Brief Summary

The project will be properly embedded in the clinical practice landscape to both provide a real-world context for research requirements gathering and research result assessment, and a practical application context from the industrial perspective. The landing is planned for cardiology solutions as carotid plaque assessment that can be value-adding features to tackle the current challenges of stroke prediction. The development of stroke prediction model could accelerate the R\&D process and land to key market ultrasound prototypes/products in an agile way. Collaboration and alignment with key market business and R\&D (China Digital Innovation CDI) through workshops and hackathons will be a unique feature of this agile project.

Sampling MethodNon-Probability Sample
Study Population

According to previous research and experience, the percentage of neovascularization grade II and above accounted for about 79% of all plaques in the enrolled patients, neovascularization grade I accounted for 21%, neovascularization grade II predicted the recurrence of stroke in the same basin 10%, neovascularization I The recurrence rate of stroke in the same watershed below grade is 6%, and the sample size is calculated to be about 100 cases. Gray-scale ultrasound shows the presence or absence of hypoechoic and iso-echoic, calcified nodules and other characteristics. The loss to follow-up rate is calculated as 10-15%. This study intends to include 2000 patients with acute anterior circulation ischemic stroke. A total of 100 patients were enrolled in this research center.

You may qualify if:

  • Age is greater than or equal to 18 years old and less than or equal to 80 years old;
  • At least one imaging examination suggests the presence of carotid artery plaque;
  • No allergy and other contraindications to ultrasound contrast;
  • Contrast-enhanced ultrasound examination of carotid artery plaque is required;
  • Volunteer to join this research project and sign informed consent.

You may not qualify if:

  • Patients who are unable to coordinate their body position or hold their breath during the ultrasound examination;
  • Patients with severe lack of clinical data;
  • During the follow-up, use drugs for the treatment of carotid plaque except lipid-lowering drugs, antiplatelet drugs, antioxidants, and calcium channel blockers;
  • Follow up those who have lost contact;
  • Ischemic stroke caused by non-carotid artery plaque shedding;
  • Patients with atrial fibrillation and other serious heart diseases;
  • A history of allergy to ultrasound contrast agents.
