Does coronary heart disease cause foot edema?

Coronary heart disease generally refers to coronary atherosclerotic heart disease, mild coronary atherosclerotic heart disease generally does not cause foot edema, but if severe coronary atherosclerotic heart disease, it is easy to cause foot edema. If the patient has mild coronary atherosclerotic heart disease, the blood vessel wall has not hardened significantly, and the systemic blood flow velocity has not been significantly affected, so it will not cause foot edema. However, if the patient has severe coronary atherosclerotic heart disease, the coronary artery will obviously harden, and abnormal stenosis or obstruction of the arterial lumen may occur, and the systemic blood circulation will be limited. At this time, there will be edema of the limbs.
