I would like to know same things. What I am not willing to accept presently is almost any answers based on the now widely discredited idea that cholesterol, HDL, LDL are the cause(s) of cardiovascular diseases. Your doctor, like most are still singing the old refrain about cholesterol and lipids -- we both may be dead of natural causes before ordinary doctors learn to sing a more accurate tune.
Suggest you browse through or search on the various articles by Duane Graveline, Malcom Kendricks, Kilmer McCully, Uffe Ravenskov, all on this site for the information most likely to be accurate and based on more accurate understanding of causes of cardiovascular diseases.
Back before I agreed to take Lipitor (one of my most stupid decisions) I too had such high LDL, as well as high triglycerides. BUT, ultrasound measurements on my cartoid arteries (big ones on each side of neck, that feed blood to brain) showed absolutely NO plaque of any kind. Ditto for subsequent measurements on femoral, etc. arteries in legs. Leaves my cardiologist with "egg on his face". He also thinks all statins are wonderful -- I try to keep poker face when he says that.
Perhaps someone that has digested all this will post some truly useful answer.
