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;
