But the PCSK9 inhibitor trial I linked on the very same post did go below 50 mg/dl. Maybe you are misreading what I was writing (I was not limiting my argument do statins, but arguing about low LDL in general) or you are actually not reading what I’m posting.
The final results for JUPITER (4 years in controlled open label) were published AFTER your linked article was published. It would be prudent if you are quoting articles written from 2013 onward.
And just to be clear: the argument for low LDL is not resting on rosuvastatin/JUPITER alone. Even pravastatin (a rather weak statin) showed lower ACM in it’s major trial designed to test for that.
You said, quote: “the RCTs often don’t show lower all cause mortality the lower the LDL (down to 50mg/dl and below). They show fewer cardiovascular deaths but not lower ACMortality”
That’s just plain wrong.
Also I was under the impression, that you are making an argument against Low LDL, thereby referencing the observational trials reporting a U-shaped relationsip. If that is not the case I apologize for the misunderstanding. So… what’s you hypothesis?
I was making a general argument for low LDL. The evidence for that is overwhelming. So just that I understand you correctly: you are in favor of low LDL - just not about aiming for 50 or below 50? If you want it specifically for below 50mg/dl - look at the PCSK9i trials. ODYSEE lowered ACM in addition to high dose statin, by targeting and achieving sub 50 mg/dl.
I see: now you are narrowing down my and your statement specifically to the below 50 mg/dl part. So you agree that low LDL in general is prudent? As for below 50mg/dl - these are the trials for PCSK9i.
I would agree that there is no strong evidence, that the general population should aim for below 50 mg/dl. Depending on the trial, ASCVD plaque regression was seen by aiming at 70mg/dl-80mg/dl - though lower levels lead to better outcomes. So if you can keep at, let’s say, 60 mg/dl for decades from early age on, that should be sufficient.
Tom Dayspring would argue, that newborns and small kids, and some hunter-gatherer tribes naturally have LDL in the range 20-40 mg/dl. And kids have a high demand for cholesterol to begin with (cell membranes). If there would a problem at very low level - why are there still kids?
