Outcome Measures

Primary Outcomes (2)

  • Diagnosis of ASCVD at baseline

    Whether participants have established ASCVD at baseline

    At enrollment

  • Major cardiovascular events

    a composite of myocardial infarction, coronary or non coronary revascularization surgery, hospitalization or emergency treatment due to new-onset or worsening heart failure, stroke or cardiovascular death

    during the 1 year follow-up

Study Arms (2)

Participants with CVD

Meeting any of the following: 1. Established coronary heart disease, including previously diagnosed myocardial infarction, previous treatment with coronary intervention or coronary artery bypass grafting, coronary artery stenosis ≥50%, or chest pain with objective evidence of myocardial ischemia (indicated by stress electrocardiogram or stress imaging) 2. Stroke

Diagnostic Test: fundus photograpgyDiagnostic Test: optical coherence tomographyDiagnostic Test: optical coherence tomography angiography

Participants with high CVD risk

Participants without CVD, but meeting at least two of the following: 1. Men aged ≥ 60 years old, or women aged ≥ 65 years old; 2. Diabetes; 3. Total cholesterol\>5.2 mmol/L, or LDL-C\>3.4 mmol/L, or HDL-C\<1.0 mmol/L; 4. Currently smoking, defined as daily smoking lasting for 1 year or more.

Sampling MethodNon-Probability Sample
Study Population

Participants with CVD, or otherwise with high CVD risk will be enrolled.

You may qualify if:

  • Three types of participants will be included, which are:
  • Participants with established coronary heart disease, including previously diagnosed myocardial infarction, previous treatment with coronary intervention or coronary artery bypass grafting, coronary artery stenosis ≥50%, or chest pain with objective evidence of myocardial ischemia (myocardial ischemia indicated by stress electrocardiogram or stress imaging)
  • Participants with established stroke.
  • Participants without coronary heart disease or stroke, but are at high risk for CVD, defined as meeting at least two of the following:
  • Men aged ≥ 60 years old, or women aged ≥ 65 years old;
  • Diabetes;
  • Total cholesterol\>5.2 mmol/L, or LDL-C\>3.4 mmol/L, or HDL-C\<1.0 mmol/L;
  • Currently smoking, defined as daily smoking lasting for 1 year or more.

You may not qualify if:

  • Participants unable to provide fundus imaging data required for the study due to the following reasons:
  • Permanent blindness, blurred vision, flying mosquito disease, or refractive medium opacity seriously affecting fundus examination, such as severe cataracts, vitreous hemorrhage, etc.
  • Macular edema, severe nonproliferative retinopathy in diabetes, proliferative vitreoretinopathy, radiation ophthalmopathy or retinal vein occlusion
  • Eyeball enucleation, eye deformities, etc.
  • Previous retinal laser therapy, injection therapy for any eye, or history of retinal surgery
  • Photosensitivity, or taking medication that can cause photosensitivity, or currently undergoing photodynamic therapy
  • Unable to cooperate with examination for collection of fundus imaging data
  • Other situations that the participants fail to provide fundus imaging data required for the study
  • Suffering from other serious diseases with an expected survival period of less than one year, such as advanced malignant tumors
  • Unable to adhere to follow-up
  • Other conditions which the researchers consider inappropriate for participants to enroll in the study
