The endothelial spaces in the inner layer of the arterial wall are large enough for almost any size or shape of LDL particle to penetrate.

"The space between cells in the inner layer of the artery wall is big enough for almost any size or shape of LDL to go through." (said at 0:34:53)

The claim states that the spaces between endothelial cells (paracellular junctions) in the arterial wall are large enough for LDL particles of almost any size to pass through. In intact arterial endothelium, normal inter-endothelial junctions are narrow (typically under 5–6 nm) and restrict passive paracellular diffusion of intact LDL particles (which measure 20–25 nm in diameter). Vascular biology research demonstrates that LDL penetration into the arterial intima occurs predominantly via active transcellular vesicular transport (transcytosis) mediated by specific receptors (such as SR-BI and ALK1) and caveolae, rather than by passive passage through wide paracellular spaces.

"To reach the subendothelial space, both LDL and HDL must cross the intact endothelium. Traditionally, this transit is explained by passive filtration. This dogma has been challenged by the identification of several rate-limiting factors namely scavenger receptor SR-BI, activin like kinase 1, and caveolin-1 for LDL as well as SR-BI, ATP binding cassette transporter G1, and endothelial lipase for HDL."

HDL particles can penetrate the inner layer of the arterial wall, bind to LDL, absorb cholesterol and triglycerides, and transport them back to the liver.

"HDL particles are capable to go through the inner layer of the artery wall, connect to LDL, and absorb cholesterol and some triglycerides out of it and bring it back to the liver, which is fantastic." (said at 0:35:56)

The speaker mischaracterizes the physiological mechanism of reverse cholesterol transport (RCT). HDL does not bind directly to LDL particles inside the arterial wall to extract cholesterol and triglycerides from them. In atherogenesis, LDL particles enter the arterial intima and are engulfed by macrophages via scavenger receptors, transforming them into lipid-laden foam cells. HDL enters the arterial intima and promotes cholesterol efflux directly from these macrophage foam cells via membrane transporters (such as ABCA1, ABCG1, and SR-BI) and aqueous diffusion, rather than binding to or clearing LDL particles directly. HDL then transports this mobilized cholesterol back to the liver for excretion.

"The original concept of a direct transfer of cholesterol from LDL to HDL has been proved to be oversimplified. Recent studies confirm direct participation of HDL in anti-atherogenesis by promoting the efflux of cholesterol contained in the foam cells that constitute atherosclerotic lesions."

"Macrophage foam cells play a critical role in the occurrence and development of atherosclerosis. The generation of these cells is associated with imbalance of cholesterol influx, esterification and efflux. CD36 and scavenger receptor class A (SR-A) are mainly responsible for uptake of lipoprotein-derived cholesterol by macrophages. Acyl coenzyme A:cholesterol acyltransferase-1 (ACAT1) and neutral cholesteryl ester hydrolase (nCEH) regulate cholesterol esterification. ATP-binding cassette transporters A1(ABCA1), ABCG1 and scavenger receptor BI (SR-BI) play crucial roles in macrophage cholesterol export." (abstract, passage verified)

Most statin clinical trials exclude patients who experience early adverse effects during run-in periods before formal randomization begins.

"Now, [clears throat] there's also a design problem in most statin trials. They remove patients who show early side effects before the formal study even begins. Meaning, there's more people that have side effects than even the studies show because they pulled them out before they even started marking the results." (said at 0:52:20)

The claim that most statin clinical trials exclude patients who experience early adverse effects during a pre-randomization active run-in phase is contradicted by trial design analyses. A systematic review evaluating large randomized controlled trials included in the Cholesterol Treatment Trialists' (CTT) Collaboration found that the majority of major statin trials did not employ an active statin run-in phase to weed out intolerant participants. Furthermore, among trials that did include a run-in phase, there was no significant difference in adherence or intolerance rates compared to trials without one, refuting the assertion that active run-in exclusions drive the low adverse event rates seen in major statin trials.

contradicts: Reasons for disparity in statin adherence rates between clinical trials and real-world obs… (European heart journal. Cardiovascular pharmacotherapy 2018) · cited 52x in the literature
"Two major conclusions arise: (i) the majority of RCTs did not have a test dose of a statin in the run-in phase. (ii) A test dose in the run-in phase was not associated with a significantly improved adherence rate within that trial when compared to trials without a test dose. Taken together, the RCTs of statins reviewed here do not suggest a bias towards an artificially higher adherence rate because of a run-in period with a test dose of the statin."
