Calcification of the aorta and coronary arteries is often indicative of coronary atherosclerosis. Aortic and coronary artery calcification may be present if a chest CT scan reveals what appears to be white material in the appropriate locations, which is a normal phenomenon that can occur with age. However, in the elderly, calcification of the aorta and coronary arteries is often associated with atherosclerotic stenosis of the coronary arteries, leading to coronary artery disease. Elderly patients are advised to undergo coronary angiography immediately after the discovery of calcification of the aorta and coronary arteries for further diagnosis, to assess the degree of coronary artery stenosis, and to consider the need for interventional therapy. After discovering calcification of the aorta and coronary arteries, patients should go to the cardiology department of the hospital for examination in a timely manner to avoid the continuous development of the condition causing coronary artery disease.
