I'm not in the enviable position of having a CAC score of zero. I have exactly the opposite, a score in the 98th percentile (as of a few years ago). My understanding is that a zero CAC score is predictive of very low risk over the next 10 years. Yet it's not a complete pass, because a CAC scan cannot detect soft plaque.

The one thing I would interject is that I had normal LDL and good HDL for decades and it was not protective for me. My CAC scan was a shock. I still didn't want to go on statins, but ultimately I decided to take them. You could try them and see if they affect you. Is there any data that it decreases your lifespan? I don't know. I would say I'd happily turn time back and go on statins if I would not have this plaque threatening to rupture unexpectedly. The zero CAC score is gold!
