is there a good correlation between carotid artery blockage and coronary artery blockage? In other words if it has been determined that one has 20 to 30% carotid blockage is there a high chance of some level of coronary artery disease?
This is a very good question, Pete. The process in which arteriosclerosis (cholesterol plaques) develop and propagate in the body is similar in both large and small vessels. So yes, those who have peripheral arterial disease (such as carotid artery disease) are often at risk of having underlying coronary artery disease as well. Treatment for all include keeping blood pressure low, lowering cholesterol levels, eating low salt/low fat foods, and maintaining good cardiovascular exercise (20-30 minutes, 4-5 times/week). The decision when to intervene (stents, surgery, etc) depends on the degree of blockage of the respective vessels and the presence of any other associated symptoms.
