83 yr female. ct for kidney stones shows calcifcation abdominal aorta and ivc. is this normal for age? ldl good hdl slightly low. bp good. a1c 5.7

Normal for age: This is a normal finding for your age. Unless there is calcification that is separated from the arterial wall, i would not be concerned about this. It does suggest that you will be prone to systolic hypertension (the top number) and that it might be hard to treat.

Calcification: Yes, calcification of aorta and IVC is usual for this age; the data you provide indicates low risk; it is helpful to know diameter of aorta - is aneurysm present?
