Summary

For patients with severe calcification or complex non-calcified plaques, we investigate wether PCCT can enable non-invasive, in vivo precise differentiation and quantitative measurement of plaque components (e.g., spotty calcification, necrotic core, fibrous tissue). Further we also study wether these quantitative imaging features can independently predict the risk of MACE in the short term and long term

Detailed description

Photon-counting detector CT (PCD-CT), as an innovative technology in the field of CT imaging, is gradually transforming the landscape of cardiac imaging. It differs significantly from conventional energy-integrating detector CT (EID-CT) in technical principles, bringing new possibilities for the diagnosis and assessment of heart diseases. This study will enrolled patients undergo standardized PCCT coronary angiography (CCTA) and make ultra-fine quantitative plaque analysis. Then at least 12 months of clinical follow-up will be performed. Finally correlation analysis between baseline plaque characteristics and follow-up endpoint events will be made.
