Aortic atherosclerosis detected by CT cannot be identified as coronary artery disease, and the two are different types of atherosclerosis. Atherosclerosis refers to pathological changes in the arteries, such as lipid aggregation, fibrous tissue proliferation and calcium salt deposition, etc. CT examination of aortic atherosclerosis refers to atherosclerotic lesions in the ascending aorta, descending aorta, thoracic aorta and abdominal aorta and other parts. Coronary heart disease, known as coronary atherosclerotic heart disease, lesions in the coronary arteries, such as the left trunk, the right coronary artery, anterior descending branch, the gyration branch and so on. The two are different lesion sites, aortic lesions do not deduce coronary artery lesions, the two are different types of atherosclerosis disease. When coronary artery disease is suspected, it is recommended to go to the cardiology department, improve the electrocardiogram, cardiac ultrasound, troponin, and if necessary, coronary arteriography, to make a clear diagnosis, and treatment according to the doctor’s instructions.
