Can HTG Cause Atherosclerosis?
Con• HTG → CVD weaker than LDL-C, partly HDL-C dependent
• Severe HTG from ↑chylomicrons not related to ↑CVD
• TG accumulation not seen in atherosclerotic plaque
• TG-lowering drugs not completely proven to ↓CVD
Pro• TG-rich lipoproteins are atherogenic (esp. cholesterol-rich remnants)
• TG lipolysis by lipoprotein lipase (LPL) → pro-inflammatory FFA (uptake by CD36 & FA binding proteins to nucleus)
• HTG causes atherogenic changes in LDL and HDL
• TG-lowering drugs ↓CVD in HTG / low HDL-C patients
• TG ~100–800 mg/dL is OFTEN associated with hyper-Apo B (ie, pro-atherogenic state)

How Should We Use Lipid Measures to Assess CV Risk in Patients with Dyslipidemia?
Key Points in NCEP / ATP III Guidelines Regarding TG
Practice Standards
• Do a fasting lipoprotein profile in all adults
• Patients with TG ≥200 mg/dL should have non-HDL-C calculated and treated to goal (=LDL-C goal + 30)
• If TG ≥500 mg/dL, lowering TG is 1st priority
• Consider Rx with fibrates or niacin if TG >200 mg/dL (or HDL-C <40 mg/dL) after statin Rx to LDL-C / non-HDL-C goals

Rationale for Non-HDL-C Assessment
• In the presence of HTG (>200 mg/dL), non-HDL-C better assesses atherogenic particles than does LDL-C1
• Unlike calculated LDL-C, non-HDL-C can be accurately measured in nonfasting patients2,3
• Non-HDL-C is highly correlated with total Apo B1
– Serum total Apo B has been shown to have a strong predictive power for severity of coronary atherosclerosis and CHD events1
• Non-HDL-C is the difference between 2 values in the standard lipid panel (ie, TC – HDL-C) and therefore incurs no additional cost1,4

Non-HDL-C Predicts CHD Better than LDL-C
• In HTG, at a given non-HDL-C level, little / no association between LDL-C and CHD
• In contrast, non-HDL-C predicts CHD at all LDL-C levels
• Non-HDL-C is a much stronger CHD risk predictor than LDL-C

Recommendations for Using LDL Particle Number Measures as Targets of Therapy
Summary and Conclusions
HTG (and low HDL-C)
• HTG and low HDL-C (with high Apo B, LDL-P, and SD LDL) is the “atherogenic dyslipidemia” common in insulin resistance / MetS and T2DM
• Both HTG and low HDL-C strongly predict CVD risk even with excellent LDL-C control on a statin
Non-HDL-C
• ↑Non-HDL-C (and ↑Apo B / ↑LDL-P) strongly predicts CVD risk
• Non-HDL-C has ATP III Rx goals (=LDL-C goal + 30)
• Several expert panels and guidelines advocate managing to Apo B / LDL-P goals in addition to Non-HDL-C
T2DM=type 2 diabetes mellitus.
How Should HTG be Managed in MetS / T2DM?

Basic Principles of CVD Risk Management
1. Systematically quantify CVD risk
2. CVD risk category determines LDL-C / non-HDL-C goals
3. Look for 2o causes of dyslipidemia and high BP
4. Treat 2o factors/contributory metabolic disorders
5. Encourage diet and lifestyle change in everyone
6. Statins & statin adjuncts to achieve LDL-C / non-HDL-C goals
7. Consider TG / HDL-C medications (fibrates, niacin, and Om-3) if HTG / low HDL-C persists

Primary Causes of HTG
Relatively common• Familial combined hyperlipidemia (FCHL)
– Variable phenotype (↑TG alone, or ↑TC alone, or both increased)– Associated with ↑↑CVD and ↑central obesity– Multiple genetic associations of unclear causal significance– “Hyper-Apo B”
• Familial HTG (FHTG)– ↑TG alone (not TC)– Associated with ↑CVD if ↑central obesity / MetS– Largely due to ↑hepatic VLDL production– Apo B is usually normal
Rare• LPL deficiency
• Apo C-II deficiency
• Familial dysbetalipoproteinemia (Type III)
• GPIHBP1 deficiency

AHA Recommendations for Om-3 FA Intake
Kris-Etherton PM et al. Circulation. 2002;106:2747-57.
Population Recommendation
Patients without documented CHD
Eat a variety of (preferably oily) fish at least twice a week. Include oils and foods rich in alpha-linolenic acid (flaxseed, canola, and
soybean oils; flaxseeds; and walnuts).
Patients with documented CHD
Consume ~1 g of EPA+DHA per day, preferably from oily fish. EPA+DHA
supplements could be considered in consultation with the physician.
Patients needing TG lowering
2–4 grams of EPA+DHA per day provided as capsules under a physician’s care
Sources of Omega-3 Acid Ethyl Esters
*Freshwater trout is also a member of the Salmonidae family. As opposed to sea trout, freshwater trout are not marine fish.Bays HE. Drugs Today (Barc). 2008;44:205-46.

Carangidae Jack mackerel
Clupeidae Herring, sardine and menhaden

Conclusions
• HTG is likely a major RF for pancreatitis & CVD– Optimal TG level is <100 mg/dL– Rx required if TG >500 mg/dL– Consider Rx if TG 200–500 mg/dL in high-risk
patients (prior CVD, T2DM, MetS, etc.)
• Treatment modes:– Diet & Exercise– Weight control– Address 2o factors– Medications
• HTG meds may CVD in pts with HTG / low HDL-C, butdata are not robust and none are FDA approved for CVD reduction

Diabetes Is a CHD Risk Equivalent
• CVD accounts for ~2/3 of deaths in people with diabetes1
• Adults with diabetes have heart disease death rates about 2–4 times higher than adults without diabetes1
• NCEP ATP III Guidelines2
– Diabetes is a major, independent risk factor for CHD and other forms of CVD
– Patients with diabetes should be managed as a CHD risk equivalent

CHD events occur in patients treated with statins
AFCAPS= Air Force Coronary Atherosclerosis Prevention Study; LIPID= Long-term intervention with pravastatin in ischemic disease; TexCAPS=Texas Coronary Atherosclerosis Prevention Study.
Conclusions
• T2DM greatly risk for
– Microvascular disease
– Macrovascular disease (CVD)
• CVD risk is high in T2DM despite statin Rx
• Residual CVD risk might be with TG / HDL meds (fibrates, niacin, Om-3) as statin adjuncts

Case 2: 49-yo Caucasian Man with T2DM, MI, and PCI 2 yrs Ago with Modestly Elevated TG
William C. Cromwell, MD
Case 2: 49-yo Caucasian Man with T2DM, MI, and PCI 2 yrs Ago with Modestly Elevated TG
Meds: Metformin 1000 mg bid, ASA 81 mg/d, atorvastatin 40 mg/d
Exam: BMI=29 kg/m2, BP=129/82 mm Hg, Waist=41”
LabsA1c 6.5%
TG 248 mg/dL
LDL-C 75 mg/dL
HDL-C 38 mg/dL
Non-HDL-C 139 mg/dL
ASA=aspirin; Dx=diagnosis; PCI=percutaneous coronary intervention.
Case 2: Treatment Approach
First, establish the patient’s risk status:49-yo man, T2DM, previous MI with PCI 2 yrs ago, nonsmoker
Risk factor Patient
Gender: Male Yes: Male
Age: >45 years Yes: 49 years
Previous MI Yes
T2DM Yes: T2DM = CHD risk equivalent
MetS: 4 of 5 RFs1. Waist >40”2. Hyperglycemia3. HDL-C <40 mg/dL4. TG >150 mg/dL5. High BP
Yes: MetS1. 41”2. Yes3. 38 mg/dL4. 248 mg/dL5. No: BP 129/82 mm Hg
This patient is very high risk
Risk status established, set goals for therapy
Case 2: Goals for Therapy
Goal Patient Treatment
BP: 120/80 mm Hg may be optimal (JNC7)
129/82 mm Hg, Not on BP Rx
Consider low dose ACEI for renal protection in T2DM
LDL-C: <100 mg/dL, optional <70 mg/dL
75 mg/dLIs relatively low LDL-C misleading? Why? What to do?
Non-HDL-C: <130 (<100 optional)
139 mg/dLNon-HDL-C high on atorva 40! Needs non-HDL-C statin adjunct
TG: <150 mg/dL (target) 248 mg/dLAddress 2o factorsLikely needs TG statin adjunct
HDL-C >40 mg/dL (target) 38 mg/dL May need HDL-C statin adjunct
A1c: <6.5% 6.5% None: He is at goal on metformin
Waist: <40”BMI: 18.5–24.9 kg/m2
(Obese: >30 kg/m2)
41”29 kg/m2
Physical activity: 30–60 minutes of daily moderate aerobic activityDiet: ↓sugars, calories & alcohol
