NCT06025305

Brief Summary

The goal of this observational study is to develop an automatic whole-process AI model to detect, quantify, and characterize plaques using coronary CT angiography in coronary artery disease patients. The main questions it aims to answer are:

  1. 1.Whether the AI model enables to detect and quantify coronary plaques compared with intravascular ultrasound or expert readers;
  2. 2.Whether the AI model enables to identify vulnerable plaques using intravascular ultrasound or optical coherence tomography as the reference standard.
  3. 3.Whether the AI model enables to predict future adverse cardiac events in a large cohort of 10,000 patients with non-obstructive CAD.

Sampling MethodNon-Probability Sample
Study Population

consecutive patients who first underwent CCTA and then Intravascular imaging in China

You may qualify if:

  • Intravascular imaging (including intravascular ultrasound or optical coherence tomography) was performed within 3 months after CCTA;
  • No change in medications or clinical symptoms during CCTA and intravascular imaging examinations;
  • Coronary artery diameter stenosis of 30% to 90% on invasive coronary imaging.

You may not qualify if:

  • Image quality of CCTA or intravascular US was inadequate to analyze;
  • Intravascular imaging was performed after percutaneous coronary intervention (PCI) or pre-dilation of the target lesions;
  • Lesions could not be co-registered between CCTA and intravascular US;
  • Missing CCTA or intravascular US data
