About this study
This ambidirectional observational cohort study builds upon and expands an existing coronary artery disease (CAD) cohort based on retinal fundus imaging (ChiCTR2200066429). A comprehensive baseline database will be established, including demographic characteristics, laboratory test results, coronary angiography findings, quantitative retinal vascular features, and multi-omics data.Artificial intelligence methods will be used to quantify retinal vascular characteristics and to develop and validate models for identifying and predicting CAD. In addition, targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays will be developed to measure previously identified CAD-related biomarkers, including metabolites and lipids, in baseline biological samples. Clinical, retinal imaging, and multi-omics data will subsequently be integrated to develop a risk stratification model for identifying individuals at high risk of CAD. Participants will be followed for cardiovascular events to evaluate the predictive performance of the model. The findings may support the development of improved strategies for CAD detection, risk assessment, and clinical management. No treatment or clinical intervention is assigned by the study protocol, and all medical decisions are made as part of routine clinical care.
Read the detailed description
This study uses an ambidirectional cohort design comprising both retrospective and prospective phases. The retrospective phase includes eligible participants identified from clinical records between June 01, 2022 and May 13, 2024. The prospective phase includes participants enrolled between May 14, 2024 and December 31, 2026, with follow-up for cardiovascular events.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of participants with coronary artery disease
Measured: Within 7 days of coronary angiography during hospitalization
Gensini Score
The Gensini score is used to assess the angiographic severity of coronary artery disease. The minimum score is 0, with no predefined maximum score. Higher scores indicate more severe coronary artery disease and a worse outcome.The Gensini score will be calculated only for patients who undergo coronary angiography and have no history of percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG).
Measured: Within 7 days of coronary angiography during hospitalization
SYNTAX Score
The Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery (SYNTAX) score is used to assess the anatomical complexity of coronary artery disease.The minimum score is 0, with no predefined maximum score. Higher scores indicate more severe coronary artery disease and a worse outcome.The SYNTAX score will be calculated only for patients who undergo coronary angiography and have no history of percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG).
Measured: Within 7 days of coronary angiography during hospitalization
Secondary outcomes (1)
Major Adverse Cardiovascular Events
Measured: At 6 months and 1 year after hospital discharge
