Interesting, Dean. Thanks for posting that.
There are some interesting studies about density of calcification, though they sometimes – I think – become clouded by a prevalence to skew the results toward statins (which increase calcification, but also density).
If you (by “you”, I mean anyone reading this) follow David Diamond or particularly Ivor Cummins on Twitter, people keep posting their CAC scores and the results are truly all over the map. People with “great” lipids getting bad results; people with super high LDL (familial hypercholesterolemia or lean mass hyper-responder type of LDL) getting great results. There are also low scores yet blockages (though these are rare).
