fwiw - I'm the owner of an astronomic CAC score - over 2600, but, BUT I have a normal stress treadmill and the ultrasound of my carotids shows no atherosclerosis. Point being - I'm NOT in line for a stroke. And as I've mentioned before, I don't think that those of us with extremely high CAC scores have coronary atherosclerosis in proportion to that score. So, we really don't know our risk for heart attack without coronary angiography. I'd do that if I weren't hypersensitive to contrast material. So it goes.
