Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

The majority of the US population has suboptimal metabolic health, often indicated by hypertension, obesity, or a combination of factors.

Well SupportedAtherosclerosis does not develop in veins, suggesting that endothelial damage is necessary for its initiation.

Well SupportedFamilial partial lipodystrophy caused by LMNA mutations leads to insulin resistance and early coronary heart disease.

Well SupportedImpaired wound healing at the endothelial level in individuals with insulin resistance prevents proper repair, leading to the initiation of atherosclerosis.

Well SupportedHypertension is primarily caused by insulin resistance unless a secondary cause is identified.

Partially SupportedLDL is not problematic unless an individual is insulin resistant and is involved in arterial healing.

Well SupportedThe number of LDL particles (LDL-P), approximated by ApoB levels, is a more accurate predictor of atherosclerosis than LDL cholesterol concentration.

Well SupportedA HOMA-IR score, calculated from fasting insulin and fasting glucose, is an indicator of insulin resistance.

Well SupportedIn individuals with insulin resistance, impaired wound healing at the endothelial level leads to the development of atherosclerotic plaques.

Well SupportedVeins transplanted into arterial circulation rapidly develop atherosclerosis.

Well SupportedPeople with familial lipodystrophy develop significant atherosclerosis despite not having elevated LDL levels.

Partially SupportedArterial injury, not LDL, is likely the initial step in plaque formation, with LDL potentially arriving as a helpful component.

Well Supported90% of the US population has pre-diabetes, indicating an epidemic of insulin resistance and a lack of optimal metabolic health.

Well SupportedAtherosclerosis develops in areas of intact endothelium where lipoproteins are retained, not in areas of arterial injury.

Partially SupportedNative LDL does not directly damage the endothelium, but oxidized LDL may cause damage after oxidation by a macrophage.

Partially SupportedInsulin resistance exists on a continuum, and any deviation from optimal metabolic health signifies some degree of insulin resistance.

Partially SupportedIndividuals without obesity or insulin resistance can still develop atherosclerosis if their LDL cholesterol is at normal levels.

Well SupportedIndividuals with abetalipoproteinemia, characterized by low LDL levels, exhibit minimal atherosclerosis.

Partially SupportedPeople with hypobetalipoproteinemia have almost no atherosclerosis.

Partially SupportedEndothelial injury initiates atherosclerosis.

Well SupportedHigher triglyceride levels are associated with higher apob levels, increasing atherosclerosis risk.

Partially SupportedBeing overweight contributes to sleep apnea, hypertension, and diabetes.

Partially SupportedCalcified plaques are generally considered protective and less likely to rupture compared to soft plaques.

Partially SupportedNormal target levels for LDL cholesterol have been lowered due to increased understanding of its association with atherosclerosis.

Partially SupportedVulnerable, soft plaques are responsible for approximately 70-80% of heart attacks.

Partially SupportedVeins are significantly thinner and less muscular than arteries.

Partially SupportedMedications are used to aid weight loss when patients stall, and the goal is to treat obesity-associated conditions.

Partially SupportedFamilial hypercholesterolemia (FH) is not the same as the general population's risk factors for atherosclerosis.
