Aortic sclerosis is not part of coronary artery disease. Coronary artery disease is the hardening of the coronary artery site, while aortic sclerosis refers to the hardening of the aortic artery site, and the two are somewhat related. Because the arteries throughout the body are a system, aortic sclerosis indicates that the coronary arteries are also likely to be sclerotic. Aortic atherosclerosis may be due to previous arteritis, atherosclerosis, and aging, all of which tend to cause aortic atherosclerosis. The majority of coronary arteries are due to atherosclerosis. For people with aortic atherosclerosis, the main thing is to actively look for the cause, and also to see if the patient has susceptibility factors such as hypertension and diabetes. If there are these risk factors and the usual lifestyle control is not good, you can choose carotid ultrasound and coronary CT to see if there is hardening of the carotid arteries and coronary arteries to determine if there is coronary heart disease or cranial vascular lesions.
