PCCT-Defined High-Risk Plaque and Future Coronary Events: The PREDICT Study
Prognostic Value of Photon-Counting Detector CT-Derived High-Risk Coronary Plaque Features for Predicting Major Adverse Cardiovascular Events: a Prospective Cohort Study
Beijing Chao Yang Hospital
500 participants

Conditions
Summary
This prospective cohort study aims to determine whether high-risk coronary plaques identified by novel Photon-Counting Detector CT (PCCT) independently predict future major adverse cardiovascular events (MACE). Participants will be followed for MACE and revascularization. The primary hypothesis is that the incidence of MACE is significantly higher in patients with PCCT-defined high-risk plaque than in those without. Additionally, patients will undergo Optical Coherence Tomography (OCT) and angiography within a month after PCCT; PCCT results will be compared with OCT in a cross-sectional analysis, and diagnostic performance will be evaluated against follow-up data.
