Inclusion criteria

✓. 18-80 years old men and women.
✓. The diagnosis and assessment of the disease meet any of the following criteria:
✓. The rest 99mTc-Sestamibi (MIBI) SPECT imaging has been completed in the past month and no imaging technical issues were leading to poor image quality. Image indicated myocardial perfusion defect of ≥ 2 segments or total resting perfusion score (SRS) ≥4.
✓. The patient has completed glucose-loaded 18F-FDG myocardial metabolic PET imaging in the last month and has not failed to diagnose because of poor image quality due to technical problems with the imaging, except for his own glucose regulation.
✓. Patients who can communicate properly with the investigators, understand and follow the study requirements, voluntarily participate, and understand and sign the informed consent.
