Study summary

This study included patients with carotid artery atherosclerotic plaques to conduct multimodal ultrasound examinations, aiming to establish a plaque vulnerability assessment model based on ultrasonic imaging indicators, clinical history, and laboratory indicators. Based on the occurrence of cardiovascular and cerebrovascular events during the 3-year follow-up period, the correlation between the vulnerability of carotid plaques and the occurrence of cardiovascular and cerebrovascular events was explored. Furthermore, a cardiovascular and cerebrovascular risk prediction model for patients with plaques was established by combining multi-dimensional data indicators such as patients\' clinical data and ultrasonic multimodal imaging data, forming a risk warning tool suitable for clinical use and providing a reference for risk management in patients with carotid artery plaques.

Research Objectives：

1. To establish a plaque vulnerability assessment model based on ultrasonic imaging indicators of plaques, clinical indicators of patients, and laboratory indicators.
2. To establish a cardiovascular and cerebrovascular risk prediction model for patients with carotid plaques by combining clinical indicators of patients and ultrasonic multimodal imaging data.
3. To screen ultrasonic imaging indicators for predicting cardiovascular and cerebrovascular events.

Eligibility

Primary outcome measure(s)

• IPN semi-quantitative grading — 36 months
  Grade 0: no microbubbles seen within the plaque; Grade 1: microbubbles limited to the plaque shoulder or adventitial surface; Grade 2: microbubbles visible at the thickest part of the plaque, the intimal surface, or extensive enhancement within the plaque
