There's something I deeply don't understand about this.
> I shared these results with a leading lipidologist who proclaimed: “Not sure if the lab or the primary care doc said an LDL-C of 116 mg/dL was fine but that concentration is the 50th percentile population cut point in the MESA study and should never ever be considered as normal.

So... the exact median value is "totally unacceptable" and "should never ever be considered as normal"? I'm open to the possibility that the US population is so deeply unhealthy that this is true, but then that needs to be argued for or at least mentioned. Like, you can't say "you're exactly average in this respect" and expect your and that's terrible to be taken seriously without any followup.
Or if I'm misunderstanding what's meant by "50th percentile population cut point" then again, I think this jargon should be explained, as it's plainly not the usual meaning of "50th percentile".
I had assumed "the MESA study population" was a particularly unhealthy bunch in terms of this measurement, meaning the 50th percentile puts one in the worst half of an already bad off group.
I don't know the exact details, but I thought the Framingham survey was just a cross-section of the population. So getting upset about a 50th percentile score makes no sense at a population level.
A quick Google says that the Mesa study was actually of people without cardiovascular disease at the beginning of the study. So again, these conclusions don't make any sense to me.
Of course it makes sense. 30% of this population will die of heart disease. You don’t want to be at the median of that population if you can avoid it. And as a society we need to move the median, not just accept it. Which means giving people better advice based on better data.
The other thing these number chasers don’t tell you is that extremely low LDL numbers are also associated with anger management issues. The stuff is used in your body to build things. You need some, and probably at least half of the number this doc is trying to say is scary. In fact in a different test he is advised to talk to his doctor about whether a 29 is safe.
Has the guidance changed that you want LDL less than 2.5x (or was it 2x?) your HDLs?
Every organ in your body that utilizes LDL can synthesize it de novo. Some of the heaviest users, like your brain, literally can't get it from your serum LDL levels - they do not pass the blood brain barrier. It is all synthesized locally.
PKCS9 inhibitors and mendelian randomization studies show that people function just fine with <10 LDL-C. (Other comments I have made in here have links to all the relevant studies)
Googling for statin and aggression links I find a fairly small set of studies with fairly disparate outcomes.
I believe there was a time they thought statins were causing mood disturbances, but I was talking about unmedicated individuals with naturally low serum levels.
