Identification for High Risk of Coronary Heart Disease Based on Quantitative Analysis of Fundus Vessels and Metabolic Molecules
2026年8月18日 更新者:Xue Yu、Beijing Hospital
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.

研究人群
The study population consists of inpatients recruited from Beijing Hospital, Beijing Haidian Hospital, and Beijing Friendship Hospital, Capital Medical University.
Eligible participants are adults older than 18 years who provide informed consent and undergo coronary angiography during hospitalization because of symptoms suggestive of myocardial ischemia or the presence of multiple cardiovascular risk factors.
This study builds upon and further expands an existing coronary artery disease (CAD) cohort based on retinal fundus imaging (ChiCTR2200066429), which began enrolling participants in June 2022.

大体时间 |

|
Gensini Score
大体时间:Within 7 days of coronary angiography during hospitalization
|
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).
|
Within 7 days of coronary angiography during hospitalization
|
|
SYNTAX Score
大体时间:Within 7 days of coronary angiography during hospitalization
|
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).
