LDL - It's not the "Bad Cholesterol" - That's Simplistic Foolery in Light of 21st Century Science

UPDATE 9th Oct 2016: Just got this article on the debacle:  http://newsroom.ucla.edu/releases/majority-of-hospitalized-heart-75668

I had approximated that around 20% of these guys were on lipid-lowering medication, which didn't change the absurdity of the result. At all. But now this article verifies it - only 21% were on the cholesterol-attacking sauce. What a farce...original blog post continues below:

Interesting twitter chat with foremost Lipid Expert Dr. Thomas Dayspring this evening - he has acknowledged the following histograms I put together, so I feel comfortable posting them(!). Basically, the Coronary Artery Disease (CAD) Histograms (Red Bars) are from a 2009 report which measured the LDL values for >130,000 people admitted with CAD issues. I pulled the US general population LDL distribution from a similar timeframe, and averaged it to match the gender split of the CAD cohort (...Green Bars). The message is:- the majority of Myocardial Infarctions (Heart Attacks) are now driven by Insulin Resistance and excessive sugar & carbohydrate in the diet, helped by Magnesium, sunlight/D, Omega3 and other nutrient deficiencies, along with excessive Omega 6 (Note - IR with concurrent Hyperinsulinemia, not the 'physiological IR of a low-carber). Reply from Dr. Dayspring: "Current NHANES data: majority of MI are explained by IR. But real message is unless >200 mg/dL - LDLc is terrible biomarker". And indeed it is - LDL should never be used to diagnose, as can be seen from my graph below (Red = Coronary Disease people, Dark Green = general population).

The Coronary Disease bus is now being driven by excess sugar/carb and probably the putrid veg oils - hence the low LDL levels seen in the afflicted. Now, if you tested them for LDL-P (the particle count), you would get a slightly different story - but 'cholesterol' is still largely junk-science - only a problem when yer Lipoproteins are damaged...or when there are far more important underlying causes at play.

the papers: CAD patients: http://www.ahjonline.com/.../S0002-8703%2808.../fulltext and NHANES data for population: http://circ.ahajournals.org/content/106/25/3237.full

Does LDL have some predictive power when measured long in advance of the disease that drives heart attacks (i.e. the inflammatory milieu)? In spite of being a junk biomarker, it has some - that's how it fooled them all decades ago. It depends totally on HDL value and much else though - which speaks to the core mechanisms. The following plot from Framingham illustrates:

LDL is intimately interactional with HDL and other properties. Because Insulin Resistance is the primary driver of heart attacks. LDL will fool you into the ground.

LDL is just a misleading messenger...of the real deal.
