What is Cholesterol?What is Cholesterol?
● a wax-like steroid molecule that plays a critical role in metabolism
● major component of cellular membranes

NECESSARY “HERO”NECESSARY “HERO”
Precursor to the steroid hormones..
●Sex hormones (testosterone, estrogens)●Mineral-corticoids…control balance of water & minerals in the kidney●Glucocorticoids…..control protein and carbohydrate metabolism, immune suppression, and inflammation ●Also the precursor to vitamin D

STANDARD LIPID PROFILESTANDARD LIPID PROFILE
● TOTAL CHOLESTEROL● LDL “BAD” CHOLESTEROL● HDL “GOOD” CHOLESTEROL● TRIGLYCERIDES
TAKE AWAY!•Standard testing provides limited insight into multiple factors underlying CVD•Identifies only 40% of people at risk for CAD•Calculated values…not measured

LDL “BAD” CHOLESTEROLLDL “BAD” CHOLESTEROL● LOW DENSITY LIPOPROTEIN: Combination
fat/protein● Lipoprotein is a carrier for cholesterol and
fats● Has 3 particle sizes● DANGER: Small,dense particles vulnerable
to oxidation● Oxidized LDL penetrates lining of artery● Contributes to development of
atherosclerosis

HDL “good” CholesterolHDL “good” Cholesterol● Removes LDL cholesterol from vessel walls● Carries it to the liver for disposal● “Reverse cholesterol transport”● Higher the HDL, less risk for CVD● CVD events reduced 11% for every 5 mg/dl
increase in HDL● More than LDL, better predictor of future heart
attack (Framingham Study)● Large HDL (HDL 2b) most active in removing
cholesterol

ADVANCED CHOLESTEROL TESTINGADVANCED CHOLESTEROL TESTING● Directly measures LDL (Bad Cholesterol)
and● Provides measurements for 15 lipid
components.● VAP (vertical auto profile), NMR, CardioIQ

PREVENTIONPREVENTION
TAKE AWAY! VAP DETECTS CARDIOVASCULAR RISK LONG BEFORE SYMPTOMS MANIFESTDATA ALLOWS PERSONAIZED PREVENTION AND TREATMENT STRATEGY
VAP tests for all present and emerging risk
factors in NCEP ATP III cholesterol guidelines

Coenzyme Q10Coenzyme Q10An enzyme produced in all tissues
Called a “coenzyme” because of its unique ability to participate in chemical reactions but remain at steady-state levels in the cell,
ANTIOXIDANT: •NEUTRALIZES FREE-RADICALS•INHIBITS LIPID PEROXIDATION (OXIDATION OF LDL)
MITOCHONDRIAL ATP SYNTHESIS: •Plays integral role in suppying energy to chemical reactions in the body

ESSENTIAL FATTY ACIDSESSENTIAL FATTY ACIDS● Essential fatty acids or EFAs,.● Fatty acids required for biological processes● Not produced in our body…must be ingested● Essential components of all cell membranes ● Three most nutritionally important omega-3
fatty acids are ● alpha-linolenic acid (ALA) ● eicosapentaenoic acid (EPA) and ● docosahexaenoic acid (DHA)
