Article Synopsis
  • Optical coherence tomography (OCT) is used to identify dangerous plaques in patients with acute coronary syndrome (ACS), but manual analysis has its limitations.
  • This study developed a deep-learning model using convolutional neural networks (CNN) and transformers to automatically predict the prognosis of ACS patients from OCT images after they underwent percutaneous coronary intervention (PCI).
  • The deep-learning model showed superior predictive performance for target vessel failure compared to traditional models, indicating that it can effectively analyze OCT images as well as or better than human observers.
