EARLY-ISR FAI

Details and patient eligibility

About

This study aims to investigate the predictive value of fat attenuation index (FAI) and related radiomics characteristics of pericoronary fat in patients after percutaneous coronary intervention (PCI) for the occurrence of in-stent restenosis (ISR) during the follow-up period (9 to 24 months). The results of this study are expected to provide an early assessment of the inflammation around the coronary lesion segment in patients after PCI, and provide a basis for early targeted intensive drug therapy in clinical practice.
