Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 100 years
  • All sexes
  • Adult, Older adult

Study population: 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.

Who may be able to join

  • Older than 18 years
  • Symptoms suggestive of myocardial ischemia or the presence of multiple cardiovascular disease risk factors
  • Underwent coronary angiography during hospitalization
  • Underwent blood sample collection during hospitalization
  • Underwent bilateral color fundus photography during hospitalization
  • Availability of complete clinical data

Who cannot join

  • History of heart transplantation or other solid-organ transplantation
  • Severe heart failure, defined as New York Heart Association (NYHA) functional class IV or left ventricular ejection fraction (LVEF) ≤20%
  • History of severe congenital heart disease, valvular heart disease, myocardial disease, pericardial disease, or aortic dissection
  • Pregnancy, breastfeeding, or plans to become pregnant during the study period
  • Progressive life-threatening disease
  • History of alcohol or drug abuse

  • Current treatment for a psychiatric disorder
  • Current receipt of radiotherapy or chemotherapy for a malignant tumor
  • Acute or chronic infectious disease

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.

  1. Number of participants with coronary artery disease

    Measured: Within 7 days of coronary angiography during hospitalization

  2. 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

  3. 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)
  1. Major Adverse Cardiovascular Events

    Measured: At 6 months and 1 year after hospital discharge

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Artery Disease, run by Beijing Hospital at 3 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 20 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with coronary artery disease (time frame: Within 7 days of coronary angiography during hospitalization). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2026.
