The odds? We'd all like to know that but we don't have enough data points. I have a colleague who has a high score, had an angiogram, and the calcium was all on the outside of the artery. While this doesn't represent atherosclerosis, we also don't know what, if any, are the long term consequences of external Ca++ build up. But we'd sure like it there rather than lining the pipes, huh..... "Doc hates vitamins"?.... sheesh....
