Despite the widespread use of stents, previous studies have shown that stent implantation mainly relieves symptoms but may not significantly improve long-term outcomes in patients with stable coronary artery disease. Identifying the types of plaques that are most likely to benefit from stenting is essential for improving personalized treatment. This study explores whether coronary computed tomography angiography (CCTA)-derived imaging biomarkers of coronary plaques are associated with increased risk of adverse outcomes after percutaneous coronary intervention (PCI). Around 2,000 patients who underwent CCTA followed by stent placement were included. Advanced software was used to quantify plaque inflammation and composition. Findings from this research may help guide personalized treatment strategies in patients undergoing PCI.
