I would argue to HAVE THE SCAN done.
Three years ago I had a TIA, which plunked me into a hospital for 2 days,
where I underwent every test imaginable. A CAC scan wasn’t included, but a
nurse suggested I get one, a freebie at this hospital. I thought 'free is good,
why not?'
I was sent home with a prescription for a “strong” statin, and they also
pushed a daily baby aspirin.
Apparently, because they were so fixated on my cholesterol, they failed to
identify my severe heart disease!
It took a five minute CT scan to discover my precarious situation, I had a
shocking, 'better write that Will', 4 digit score!

I immediately dove into researching just how I had gotten myself into such
a pickle, and how I might get the hell out.
I was a grain-a-holic vegetarian for 35 years, and I learned from the Fat
Emperor, that all those processed grains and sugars caused an ongoing train
wreck inside my arteries.
Now I eat nothing processed, I’m on a strict Ketogenic diet, which I’m
convinced is going to be my salvation.
So, I think the scan my have saved my bacon!, Bacon.... yes!, it’s time to eat!

PS-
Another way to indirectly check your heart health, and avoid being zapped
with the scan, would be to have a blood test, including insulin. That could
also show you if you're heading for the rocks.
