Yes, definitely doing a lot of reading since I got my score (2534) this past week (age 60). Everything I've read so far indicates you CAN'T lower your CAC score. I recall reading one story where someone's CAC score from 84 to 186 to 554 over a 20 year time span. Not sure if that's the norm or not.

There are just so many variables to consider from this test score (e.g. where the calcium is deposited - inside the artery, outside the artery, inside the artery walls, how much soft plaque do you have, how much blockage do you have, etc.). Can't wait to see my cardiologist in two weeks to see what he thinks about my score.
