Inclusion Criteria:
Inclusion criteria for CSAP
- Patients should meet the diagnostic criteria of coronary heart disease, which includes the following items: 1)confirmed old myocardial infarction (MI), or a history of percutaneous coronary intervention(PCI), or coronary artery bypass grafting; 2)50% or more luminal stenosis in at least one coronary artery or major branch segment confirmed by coronary angiogram or CT angiography; 3) myocardial ischemia indicted by exercise stress radionuclide myocardial imaging; 4) treadmill exercise testing is positive (for male patients);
- Patients should meet the diagnostic criteria of CSAP and the Canadian Cardiovascular Society(CCS) classification for CSAP is level II or III;
- The medical history of angina pectoris ≥3 months, with at least 2 episodes per week in the last month;
- 35 ≤ age ≤65 years, male or female;
- Patients have clear consciousness and could communicate with others normally;
- Patients could understand the full study protocol and have high adherence. Written informed consent is signed by themselves or their lineal kin.
Inclusion criteria for health volunteers
