Learning Objectives
Introduction and Overview
  • At the conclusion of this program, participants
    will be able to
  • Increase the ability to identify patient types
    at risk for
  • hypertriglyceridemia and, if present, to
    treat the condition to improve
  • outcomes
  • Recognize the complex etiology of
    hypertriglyceridemia and the link
  • to cardiovascular disease
  • Appreciate the need to measure triglyceride
    levels in patients at risk,
  • even those that may have normal LDL-C levels
  • Assess the efficacy and safety of current
    first-line and adjunct
  • therapies for hypertriglyceridemia
  • Formulate patient specific treatment regimens
    that may include
  • combination regimens that will improve
    patients prognosis

Non-HDL-Cholesterol
  • Very low-density lipoprotein (VLDL)
  • Made in the liver1
  • TG-rich1
  • Atherogenic2
  • Intermediate-density lipoprotein (IDL)
  • Formed from VLDL by TG lipolysis1
  • Also known as a VLDL remnant particle1
  • Atherogenic2
  • Low-density lipoprotein (LDL)
  • Formed from IDL due to further TG lipolysis1
  • Taken up by the liver and other organs via the
    LDL receptor1
  • Major atherogenic particle2
  • sdLDL is a highly atherogenic form of LDL that
    may occur under high TG levels1
  • High-density lipoprotein (HDL)
  • Carries cholesterol away from artery wall (and
    other peripheral tissues) for metabolism or
    excretion1
  • Other possible antiatherogenic effects include
    anti-inflammatory and antioxidant actions, and
    improvement in endothelial function1

goal. bPrimary aim of therapy is to reduce risk
for pancreatitis through TG lowering first, then
focus on LDL-C. cTo achieve nonHDL-C goal (set
at 30 mg/dL higher than LDL-C goal), intensify
therapy with LDL-Clowering drug, or add

Summary
  • Not all TG are created equal, think atherogenic
    particles, not just overall TG levels
  • TG-associated CHD risk can be assessed by looking
    at the standard lipid profile
  • Non-HDL-C should be lt 30LDL goal
  • TG/HDL ratio should be lt 3.8
  • Omega-3 acid ethyl esters at doses of 4 g/d are
    effective TG-lowering agents
  • Increased RBC Omega-3 fatty acid levels are
    associated with reduced risk for CHD events,
    especially sudden cardiac death

Ms. Jacobs-Treatment Plan
  • A nicotine patch, buproprion prescription, and
    smoking quit date (her upcoming birthday) will
    assist her in smoking cessation.
  • She will rejoin Weight Watchers and see a
    nutritionist for more education on eating a
    heart-healthy diet.
  • She agrees to limit her alcohol use to 1 drink on
    the weekends.
  • She also commits to taking a brisk 30-minute walk
    in the evenings around her neighborhood most days
    of the week.

58
Ms. Jacobs-3 Months Later
  • Ms. Jacobs happily reports that she has lost 10
    pounds, and she is walking 30 minutes most days
    of the week. She is still smoking, but she has
    cut back to 1 pack a week.
  • Her blood pressure is 134/78 mmHg.
  • Dr. Wright applauds Ms. Jacobs for her weight
    loss and exercise efforts and encourages her to
    continue, but he recommends that she initiate
    drug therapy to get her lipids under better
    control and to reduce her cardiovascular risk.

59
Pharmacological Options
60
Statin Mechanism of Action and Clinical Rationale
  • Competitive inhibitors of HMG CoA reductase,
    rate-limiting step in cholesterol biosynthesis
  • Reduction in TG due to decreased VLDL synthesis
    and clearance of VLDL remnants by apo B/E (LDL)
    receptors
  • Reduction in oxidized and small dense LDL
    subfractions and reduce remnant lipoprotein
    cholesterol levels (reduction of CE transfer from
    LDL to VLDL)

61
Statin Side Effects
  • Generally tolerable and safe
  • Myopathy
  • Myalgias (2-11), myositis(0.5), rhabdomyolysis
    (lt0.1)
  • Few weeks-4 months onset
  • Hepatic
  • 0.5 to 3 persistent elevations in LFTs in first
    3 months and dose-dependent
  • Several randomized trials have found no
    difference compared with placebo

62
Evolving Treatment Paradigm
  • Statin monotherapy reduces risk, but significant
    residual risk remains
  • Future of therapy is aggressive management of
  • LDL-C, Non-HDL-C, TG, and HDL-C
  • Combination therapy increasingly important
  • Addresses multiple risk contributors
  • Effective through multiple mechanisms

63
Fibrates Mechanism of Action and Clinical
Rationale
  • Fibrates activate the nuclear transcription
    factor peroxisome proliferator-activated
    receptor-alpha (PPARa) and
  • Upregulate genes for apolipoprotein A-I, fatty
    acid transport protein, fatty acid oxidation, and
    possibly lipoprotein lipase
  • Downregulate the apolipoprotein C-III gene
  • Reduce VLDL-C TG formation
  • Serum TG lowering and increased synthesis of
    apolipoproteins raise HDL-C
  • Extra-atherogenic, small, dense LDL-C converted
    to normal-sized LDL-C

Fibrates Side Effects
  • Fibrates are generally well tolerated1
  • GI side effects are the most common complaints
  • Adverse drug interaction
  • Gemfibrozil- inhibits glucuronidation of
    lipophilic statins and increases levels thus
    increased risk of myopathy.

67
Ms. Jacobs - 3 months Later
  • Ms. Jacobs reports that she is tolerating the
    gemfibrozil well. Her liver function tests are
    within the normal range.
  • Although her TG level has improved, Dr. Wright
    recommends adding another agent to optimize her
    levels.

68
Niacin Mechanism of Action and Clinical Rationale
  • Niacin appears to modify lipids by
  • Inhibiting mobilization of free fatty acids and
    lipoprotein synthesis
  • Decreasing HDL-C catabolism and VLDL-C
    production
  • Shifting LDL-C from small, denser LDL-C particles
    to larger, more buoyant LDL-C particles

Niacin Side Effects
  • Flushing (less common with controlled release)
  • Nausea, paresthesias, pruritis
  • Elevation of hepatocellular enzymes and possible
    hepatotoxicity, jaundice and fulminant hepatitis
  • Insulin resistance and worsening hyperglycemia
  • Hyperuricemia
  • Hypotension in combination with other
    vasodilators
  • (can increase unstable angina)

71
Using Niacin
  • Tolerability can be enhanced by
  • Initiating therapy with small doses taken with
    meals and slowly titrating upward
  • Taking aspirin or other NSAID prior to the
    morning dose
  • Avoiding taking niacin with alcohol, spicy foods,
    or hot beverages
  • Avoiding interruptions in niacin therapy
  • Using newer formulation/extended-release niacin
    instead of immediate-release niacin
  • Educating patients about the possibility of side
    effects
