There is push back on the high LDL leads to cacium build-up in arteries (being specific instead of just "longevity").

The challenge is that some people, like myself, have outrageously high LDL, yet no calcium build-up in arteries via calcium score testing.

This is why ApoB is the newer more common test. Molecules containing ApoB can stick to the walls of arteries, and the theory is that the more ApoB molecules in the blood, the more likelihood of a molecule sticking and then becoming calcified.

If you have an auto-immune disease or diabetes, which increases the amount of time it takes for tears in the arteries to repair, you have a longer exposure time of fats sticking to the arterial walls which increases the likleihood of calcifying.

However, that doesn't mean that everyone with high LDL and high ApoB are at higher risk.

This is why I went for the calcium score. Don't show me the things that might lead to calcium build up later, just measure my calcium levels and let's see if I am currently at risk, and we can keep monitoring this.

Doctors are still trying to push me on to statins, but without a history of heart-disease and every other biomarker being off the charts high, I am taking that risk myself, knowing that calcium score is 0, so my suspected risk is actually very low.

Long answer, but hopefully that clarifies the understanding.

I'm not a doctor, I work in neurotech so am around health and have gone through this process myself.
