Hi Penn, No a CCS is not the same as an angiogram. I did learn that. CCS is non-invasive and shows images of Coronary Calcium and plaque in your arteries. You then are given a Coronary Calcium score that is an objective measure of how far along your "hardening of the arteries" is. An angiogram, I believe focuses more on images of blood flow through your coronary vessels. It does not, to my knowledge, specifically show the Coronary Calcium/plaque pictures or quantify by a score your level of "clogged arteries". I refreshed my memory on angiograms by skimming a Wikipedia article on what it does and doesn't do. The CCS is considered by most Drs. to be the best predictor of heart attack risk according to numerous articles I have read.
