2/ For a relevant example-- this study makes direct comparisons on symptomatic ("chest pain") patients ultimately diagnosed AMI (acute myocardial infarction, aka heart attack) vs symptomatic yet diagnosed as not having had an AMI... journals.sagepub.com/doi/full/10.41…
3/ "There were significant decreases in TC, LDL and HDL levels in both STEMI and NSTEMI patients as compared to normal subjects; however, patients with chest pain did not show any significant change in these lipids."
4/ In other words, presenting with chest pain but having CAD ruled out shows no statistically significant difference with controls.
(As an aside, the study linked is worth the read in its own right given possible prognostic value of risk severity re presented lipid markers)

2/ First, be sure to check out this short thread from the lead author, @MaBMortensen.
2 quick notes:
a) While there'll be lots of data appreciated by LDL skepticism, @MaBMortensen maintains LDL-C is still "an important causal RF"
b) Usual epi caveats, etc
3/ Okay, so if you've followed me a while, you know just how incredibly thankful I am of studies that seek to avoid common risks of selection bias (Even if entirely unintended).
This study had the distinct advantage of categorically scooping its population directly...
1/ Reminder: I realize it’s the single hardest concept to get across, but for all these years I have and continue to suggest there’s a crucial case of lipoprotein profiles as often more a reflection of disease than the independent drivers of it. (ie — from 2018 re general👇)
2/ For example, I certainly know so much more on the workings of #LEM* than when I tweeted this from 2018, but does the foundation still hold up… do I think this is more relevant or less? Definitely more!
(*Obligatory mention of @nicknorwitz here and others re coming paper!)
3/ The bottom line is that while the independent causal role of lipoproteins (whether LDLp, sdLDL, oxLDL, glLDL, etc) are well worth examining. We should likewise investigate how *both* lipid profiles and CVD can be downstream of poor lipid metabolism.
2/ They've kindly agreed to provide a coupon code "CITIZEN" for their package to help get both a discount and allow opting in your anonymized data to our OYL anonymous data pool. (Just like we do at our site)
No, there's no $$$ or compensation for us or anything like that...
3/ ... Which might seem confusing since they are technically a competitor given they offer bloodwork as well.
But hello -- @siobhan_huggins and I are *always* game for *everyone* finding what works for them. And seriously, I think this platform is a strong step forward.
2/ Occasionally I get a doctor (often a Dermatologist) ask if I've checked for hypothyroidism given it can be associated with loss of the outer eyebrow.
However, this is usually resolved when they see my eyebrows up close given it doesn't follow the same pattern...
3/ Often there is a pronounced pinching or abrupt halt in the pattern of spread. But to be sure, this is more of what I hear from them. I haven't researched much on it given I already knew this pattern was common in my family-- but this study was helpful👇 ncbi.nlm.nih.gov/pmc/articles/P…
But in this late moment of calm before the weekend, I'm finding myself truly humbled that our #LMHRpaper is finalized and has crossing so many interested eyes.
I hope many will agree with us this phenomenon is well worth researching.
2/ Via @nicknorwitz: "... this paper has stimulated vigorous discussion, risen to the top of its journal for all time reads, and is among the top 15 trending papers across all American Society of Nutrition associated journals for the year 2021." nutrition.org/15-trending-nu…
3/ There's quite a bit more work in the pipeline from the many great collaborators I have the honor to be working with. We're passionately working on a #LipidEnergyModel paper, the #LMHRstudy (currently underway), and a couple other projects I can't announce just yet...
