I will let Dave Feldman or Nick Norwitz do that explanation. Lots of Youtube videos doing so.

I think the important thing about the research is it shows that not everyone with high LDL is subject to coronary calcification and subsequent heart disease because of it. It opens up the current medical understanding of LDL and its importance in heart disease.

If you go to a heart disease risk calculator LDL shows very little influence. You can keep all the other risk factors the same and change only the LDL from low to high and it will make no or very little difference in the risk factor. So the science is already up to date in its risk assessment yet the medical community still seems to be sticking on the "lower is better" theme by doctors still prescribing statins for high LDL.

Takes ten to twenty years for the medical community to catch up to the science. Probably will take a new generation of doctors to lose the dogma of the past.
