Ok.....what I see is low CAC, high Lp(A), rising HDL and rising LDL....no reported triglycerides which would be helpful.

CAC only looks at hard plaque not soft plaque....CAC is a picture in time that is frequently zero before about 60 years old or thereabouts. A CCTA is usually used to find a more complete picture if the doctor feels that it is needed.

Lp(A) is more of a future indicator of which way your body may age, plus a major risk factor for the aortic valve.
Without hormone therapy and probably even with BHRT or HRT, albeit lessened, your cardio system will continue to age and be driven by your life style and genetics, Lp(A) is one of these.

ApoB, blood test, might help clarify the LDL by showing the number of plaque forming particles.
But...
It looks like your doctor feels that the higher LDL and the high Lp(A) will be driving your cardio system as you age. So the dr wishes to lower the LDL to lower your risk of cardio plaque forming driven by your genetics, Lp(A) in this case. Basically, your doctor is looking at future problems. It is much easier to prevent a problem than to "fix" an existing problem with plaque etc.

I actually have a similar problem. I have had an array of cardio tests which I requested. My very high HDL and low optimal triglycerides have blinded most doctors to any possible cardio problems. I had a borderline Lp(A) and ApoB, very high HDL, slightly elevated LDL and low triglycerides. My CAC was below 11 in one artery with one valve showing mild calcification, both these areas are where plaque occurs with age, due to the way the blood flows. I am in my 70s so this is a good age to see how the body is using my mixed bag of cardio numbers, earlier in my 50s or 60s probably nothing would have been found on the CAC scan. A mixed bag but heavy leaning towards "no problem".
I am having an ultrasound next week to check that valve just to make sure that the mild plaque is not in a place to impede the valve.
But right now no statins etc are being prescribed.
