  • Cardiovascular diseases (CVD) are the main cause
    of morbidity and mortality among the Saudi
    population1
  • A significant proportion of hospital admissions
    is due to CVD, whether acute or chronic or to
    cardiac procedures including angiograms2

Hyperlipidemia
  • Michele Ritter, M.D.
  • Argy Resident February, 2007

7
The story of lipids
  • Chylomicrons transport fats from the intestinal
    mucosa to the liver
  • In the liver, the chylomicrons release
    triglycerides and some cholesterol and become
    low-density lipoproteins (LDL).
  • LDL then carries fat and cholesterol to the
    bodys cells.
  • High-density lipoproteins (HDL) carry fat and
    cholesterol back to the liver for excretion.

8
The story of lipids (cont.)
  • When oxidized LDL cholesterol gets high, atheroma
    formation in the walls of arteries occurs, which
    causes atherosclerosis.
  • HDL cholesterol is able to go and remove
    cholesterol from the atheroma.
  • Atherogenic cholesterol ? LDL, VLDL, IDL

9
Atherosclerosis
10
Causes of Hyperlipidemia
  • Diet
  • Hypothyroidism
  • Nephrotic syndrome
  • Anorexia nervosa
  • Obstructive liver disease
  • Obesity
  • Diabetes mellitus
  • Pregnancy
  • Obstructive liver disease
  • Acute heaptitis
  • Systemic lupus erythematousus
  • AIDS (protease inhibitors)

11
Dietary sources of Cholesterol
Type of Fat Main Source Effect on Cholesterol levels
Monounsaturated Olives, olive oil, canola oil, peanut oil, cashews, almonds, peanuts and most other nuts avocados Lowers LDL, Raises HDL
Polyunsaturated Corn, soybean, safflower and cottonseed oil fish Lowers LDL, Raises HDL
Saturated Whole milk, butter, cheese, and ice cream red meat chocolate coconuts, coconut milk, coconut oil , egg yolks, chicken skin Raises both LDL and HDL
Trans Most margarines vegetable shortening partially hydrogenated vegetable oil deep-fried chips many fast foods most commercial baked goods Raises LDL
12
Hereditary Causes of Hyperlipidemia
  • Familial Hypercholesterolemia
  • Codominant genetic disorder, coccurs in
    heterozygous form
  • Occurs in 1 in 500 individuals
  • Mutation in LDL receptor, resulting in elevated
    levels of LDL at birth and throughout life
  • High risk for atherosclerosis, tendon xanthomas
    (75 of patients), tuberous xanthomas and
    xanthelasmas of eyes.
  • Familial Combined Hyperlipidemia
  • Autosomal dominant
  • Increased secretions of VLDLs
  • Dysbetalipoproteinemia
  • Affects 1 in 10,000
  • Results in apo E2, a binding-defective form of
    apoE (which usually plays important role in
    catabolism of chylomicron and VLDL)
  • Increased risk for atherosclerosis, peripheral
    vascular disease
  • Tuberous xanthomas, striae palmaris

13
Checking lipids
  • Nonfasting lipid panel
  • measures HDL and total cholesterol
  • Fasting lipid panel
  • Measures HDL, total cholesterol and triglycerides
  • LDL cholesterol is calculated
  • LDL cholesterol total cholesterol (HDL
    triglycerides/5)

14
When to check lipid panel
  • Two different Recommendations
  • Adult Treatment Panel (ATP III) of the National
    Cholesterol Education Program (NCEP)
  • Beginning at age 20 obtain a fasting (9 to 12
    hour) serum lipid profile consisting of total
    cholesterol, LDL, HDL and triglycerides
  • Repeat testing every 5 years for acceptable
    values
  • United States Preventative Services Task Force
  • Women aged 45 years and older, and men ages 35
    years and older undergo screening with a total
    and HDL cholesterol every 5 years.
  • If total cholesterol gt 200 or HDL lt40, then a
    fasting panel should be obtained
  • Cholesterol screening should begin at 20 years in
    patients with a history of multiple
    cardiovascular risk factors, diabetes, or family
    history of either elevated cholesteral levels or
    premature cardiovascular disease.

15
Goals for Lipids
  • LDL
  • lt 100 ?Optimal
  • 100-129 ? Near optimal
  • 130-159 ? Borderline
  • 160-189? High
  • 190 ? Very High
  • Total Cholesterol
  • lt 200 ? Desirable
  • 200-239 ? Borderline
  • 240 ? High
  • HDL
  • lt 40 ? Low
  • 60 ? High
  • Serum Triglycerides
  • lt 150 ? normal
  • 150-199 ? Borderline
  • 200-499 ? High
  • 500 ? Very High

16
Determining Cholesterol Goal(LDL!)
  • Look at JNC 7 Risk Factors
  • Cigarette smoking
  • Hypertension (BP 140/90 or on anti-hypertensives)
  • Low HDL cholesterol (lt 40 mg/dL)
  • Family History of premature coronary heart
    disease (CHD) (CHD in first-degree male relative
    lt55 or CHD in first-degree female relative lt 65)
  • Age (men 45, women 55)

17
Determining Goal LDL
  • CHD and CHD Risk Equivalents
  • Peripheral Vascular Disease
  • Cerebral Vascular Accident
  • Diabetes Mellitus

18
LDL Goals
  • 0-1 Risk Factors
  • LDL goal is 160
  • If LDL 160 Initiate TLC (therapeutic
    lifestyle changes)
  • If LDL 190 Initiate pharmaceutical treatment
  • 2 Risk Factors
  • LDL goal is 130
  • If LDL 130 Initiate TLC
  • If LDL 160 Initiate pharmaceutical treatment
  • CHD or CHD Risk Equivalent
  • LDL goal is 100 (or 70)
  • If LDL 100 Initiate TLC and pharmaceutical
    treatment

19
Treatment of Hyperlipidemia
  • Lifestyle modification
  • Low-cholesterol diet
  • Exercise

Case 1
  • A 55-year-old woman without symptoms of CAD seeks
    assessment and advice for routine health
    maintenance. Her blood pressure is 135/85 mm Hg.
    She does not smoke or have diabetes and has been
    postmenopausal for 3 years. Her BMI is 24.
    Lipoprotein analysis shows a total cholesterol
    level of 240 mg/dL, an HDL level of 55 mg/dL, a
    triglyceride level of 85 mg/dL and a LDL level is
    180 mg/dL. The patient has no family history of
    premature CAD.

23
Case 1 (cont.)
  • What is the goal LDL in this woman?
  • What would you do if exercise/diet change do not
    improve cholesterol after 3 months?
  • How would your management change if she
    complained of claudication with walking?

24
Case 2
  • A 40- year-old man without significant past
    medical history comes in for a routine annual
    exam. He has no complaints but is worried
    because his father had a heart attack at the
    age of 45. He is a current smoker and has a
    23-pack year history of tobacco use. A fasting
    lipid panel reveals a LDL 170 mg/dL and an HDL of
    35 mg/dL. Serum Triglycerides were 140 mg/dL.
    Serum chemistries including liver panel are all
    normal.

25
Case 2 (cont.)
  • What is this patients goal LDL?
  • Would you start medication, and if so, what?

26
Case 3
  • A 65 year-old woman with medical history of Type
    II diabetes, obesity, and hypertension comes to
    your office for the first time. She has been
    told her cholesterol was elevated in the past and
    states that she has been following a low
    cholesterol diet for the past 6 months after
    seeing a dietician. She had a normal exercise
    stress test last year prior to knee replacement
    surgery and has never had symptoms of CHD. A
    fasting lipid profile was performed and revealed
    a LDL 130, HDL 30 and a total triglyceride of
    300. Her Hgba1c is 6.5.

27
Case 3 (cont.)
  • What is this patients goal LDL?
  • What medication would you consider starting in
    this patient?
  • What labs would you want to monitor in this
    patient?

29
Why Bother?
  • Optimum treatment of lipids helps in the primary
    secondary prevention of ASCVD still our
    nations 1 killer

30
Why Bother?
  • ASCVD has been 1 cause of death every year since
    1900 with exception of 1918.
  • 50 of CVD diagnoses and 15 of CVD deaths are in
    patients lt 65 years of age
  • Many young adults have 2 or more risk factors
    that go unrecognized and untreated.
  • HUGE opportunity to prevent disease!!

31
NCEP/ATP III 15 May 2001
  • www.nhlbi.nih.gov
  • LDL goals lowered
  • Raised acceptable HDL to 40
  • Lowered TG goal to 150
  • Risk Factor assessment enhanced with the 10-yr
    Framingham risk calculator
  • Added the Metabolic Syndrome to Tx

32
NCEP/ATP III 9 Steps
  • Step 1 Obtain, complete fasting lipids.
  • Interpret LDL lt 100mg/dl optimal
  • LDL 100-129 near optimal
  • LDL 130-159 borderline high
  • LDL 160-189 high
  • LDL gt190 very high
  • (mg/dl x 0.0259mmol/l SI units)

33
NCEP/ATP III
  • Step 2 Identify if patient has CAD or equivalent
    (PAD, DM, AAA, Carotid)
  • Step 3 Risk factor assessment (HTN, FHx, Tob,
    Age Sex, HDLlt40 or gt60)
  • Step 4 If 2 or more risk factors do Framingham
    10-yr risk assessment.

41
NCEP/ATP III Step 6
  • Initiate Therapeutic Lifestyle Changes (TLC)
  • AHA Step 2 diet
  • Soluble fiber 10-25gm/day
  • Plant sterols/Sitostanol (Benecol, Take Control
    margarines) - lower LDL 10
  • Increased exercise
  • Weight management

42
NCEP/ATP III Step 7
  • Add drug therapy simultaneously to TLC in
    patients with CHD or equivalent. Add drugs after
    3 months if TLC not effective in other risk
    categories.
  • Best unbiased source for review of drug
    treatment The Medical Letter Choice of lipid
    regulating drugs 432001,pp43-48 and
    2003177-79.

43
Drugs Step 7 (cont.)
  • Resins- (cholestyramine,colestid, colesevelam)
    lower LDL adjunct to statins GI side
    effects/malabsorption issues
  • Niacin- miracle agent, cheap moves every
    parameter in the right direction. But, side
    effects problematic. NIASPAN easier to
    tolerate. Need slow dose titration and pre-med
    with ASA. Caution with Diabetes can worsen
    glycemic control if HBA1C gt7.5 at baseline. Most
    potent agent at increasing HDL.

44
Drugs Step 7 (cont)
  • Fibrates (fenofibrate, gemfibrozil) lower TG
    and raise HDL. Can combine with statins but
    caution re hepatic side effects. Cutting statin
    dose by ½ is good rule. Fenofibrate qd less
    side effects, gt
  • If combining w/ a statin use fenofibrate
    gemfibrozil has gt rates of rhabdomyolysis

45
Newer Drugs Step 7 (cont.)
  • Ezetimibe (Zetia)- new class that inhibits the
    intestinal absorption of cholesterol. Lowers LDL
    17, TG 6, increases HDL by 1.3. Combined with
    a statin increases effects of statin by 10-15
    w/o side effects. VERY well tolerated at 10mg/d.

46
Newer Drugs Step 7 (cont)
  • Lovastatin Niacin (Advicor)- in fixed combos
    20/500, 20/750, 20/1000. Increase dose monthly up
    to max 40/2000. Max dose w/ LDL decrease 45, TG
    42, and HDL increase by 41. Causes less
    flushing and hepatic effects than any niacin
    formulation. Greater risk of myopathy than a
    statin alone.

47
Newer Drugs Step 7
  • Simvastatin(10/20/40/80) Ezetimibe 10mg
    VYTORIN
  • OMACOR concentrated omega-3s 4 capsules 12
    OTC fish oil capsules
  • Can interfere with clotting times caution in
    folks on warfarin

48
Drugs Step 7 (cont.)
  • Statins- All w/ anti-inflammatory effects. None
    safe in pregnancy. All are more potent by 10-15
    with evening dosing.
  • - muscle pain 1-5
  • - hepatitis (transaminasesgt3x nl.) 0.5
  • - rhabdomyolysis rare incidence rates per
    million Rxs pravastatin0.04, lovastatin0.19
  • atorvastatin 0.04, simvastatin 0.12.
  • (cerivistatin was 16-80x these
    rates!!)

49
Drugs Step 7 (cont.)
  • Atorvastatin great LDL TG lowering
  • Lovastatin take w/ food generic version
  • Pravastatin least drug interactions due to
    different elimination pathway take on empty
    stomach
  • Simvastatin lots of prevention data, potent
  • Fluvastatin less potent poor prevention data
  • Rosuvastatin most potent 5 - 40 mg (CRESTOR)
    may raise HDL a bit more lower TG. Caution w/
    CrCllt30cc/min and in Asian subpopulations at
    higher doses.

50
Statin Pearls
  • Elevated transaminases on statins (unless
    reaching 3x normal), are not a reason to stop the
    statin they are are a reason to watch closely.
  • Statin side effects are often agent specific, not
    always class specific.
  • Unexplained myalgias may occur on statins without
    CK elevation. Try a different statin.

51
Statin Pearls
  • Rhabdomyolysis is uncommon unless CK is elevated
    to 10 x normal. Usually occurs in patients with
    multiple co-morbidities.
  • Unless you enjoy driving yourself nuts do not
    check CK serially in patients on statins.
    Remember vigorous yard work will bump your CK!
    Some think a baseline CK may be helpful.
  • But what about the PROVE-IT study? (NEJM 8
    April 2004)

52
PROVE-IT Trial
  • Designed to PROVE that 80mg atorvastatin was no
    better than 40 mg pravastatin in secondary
    prevention.
  • But, atorvastatin was superior as early as 30
    days of therapy. In just 24 mths the
    atorvastatin group (meanLDL62) had 16 less of
    all CV events. 28 less mortality than
    pravastatin group (meanLDL95)

53
PROVE-IT Trial
  • WOW!
  • Evidence from mammalian species had shown that
    atherogenesis stops reverses at an LDL lt80
    now some clinical outcome data.

54
NCEP Update 13 July 2004
  • Circulation 13 July 2004227-239
  • Added the results of PROVE-IT, HPS, PROSPER,
    ALLHAT, ASCOT
  • Confirmed ATP-III and added that in very high
    risk an LDL goal lt70 was optional
  • For patients at moderately high risk 10-20
    Framingham risk LDL lt100 new goal
  • Felt that drug treatment should aim for at least
    a 30-40 LDL reduction.

55
Updated ATP-III Guidelines

56
TNT StudyTreat to New Targets
  • NEJM 7 April 2005 Prospective trial at lowering
    LDL well below 100mg/dl in adults with CHD
    (secondary prevention)
  • 10,001 patients 2 groups for 4.9 years with mean
    LDL 99mg/dl before study
  • 10 mg atorvastatin (mean LDL101mg/dl)
  • 80 mg atorvastain (mean LDL77mg/dl)

57
TNT - Results
  • Side Effects increased LFTs in 0.2 of patients
    on low dose and 1.2 on high dose. No change in
    rhabdomyolysis risk.
  • Results Relative risk reduction of 22 and
    absolute risk reduction of 2.2 in major
    cardiovascular events for group with LDL lt80
    versus group with LDL101.
  • More evidence to lower our LDL goals

58
NCEP/ATP III Step 8
  • Identify Metabolic Syndrome (3 of 5)
  • SBPgt130, FBSgt110, TGgt150, HDLlt40 in men and lt50
    in women, waistgt40men, 35women
  • Aggressively
  • Treat underlying causes of overweight and
    physical inactivity.
  • Treat HTN, use ASA for CHD patients

59
NCEP/ATP III Step 9
  • Treat elevated TG (gt150mg/dl)
  • First lower LDL if TG still gt200 consider
    adding/increasing drug therapy
  • But, if TG gt500mg/dl, first lower triglycerides
    to prevent pancreatitis. When they are lt500 then
    return to LDL lowering
  • Treat HDL lt40 after lowering LDL.

60
CASES
  • All real cases. No perfect answers.
  • All present real Family Practice dilemmas.
  • Will use the evidence to help formulate a best
    answer.
  • Use cases to convey cutting edge info.

61
Case 4 Middle-of the Road
  • 45 year old woman who on a routine lipid screen
    has the following values
  • TC 203 HDL48 TG 155 LDL 124
  • PMHx negative, smoker
  • Meds daily vitamin
  • FHx MI in F age 60, M age 64
  • PE 65 130lbs P72 BP118/68

62
Case 4 Middle of the Road
  • Risk Factors 2 Framingham 5 risk
  • NCEP/ATP III says that she is at her LDL goal
    e.g. lt130
  • But, concerns remain FHx, Smoking, HDL is lt50
    TG gt150 both less than ideal.
  • What do you do with this middle-of-the-road
    risk profile?

63
Case 4 Middle of the Road
  • Consider a new idea measure her hs-CRP
  • Facts CRP is a marker of inflammation.
  • ASCVD is a disease of inflammation
  • Multiple prospective epidemiological (vs.
    interventional studies) have shown that CRP can
    predict MI,CVA, PAD, sudden cardiac death.

64
Case 4 Middle of the Road
  • Hs-CRP assays are now widely available can check
    non-fasting, anytime of day.
  • lt 1mg/l low risk
  • 1-3mg/l moderate risk
  • gt3mg/l high risk
  • gt10mg/l invalid for cardiac risk
    predictionconsider 1 inflammatory disease,
    trauma, serious infection.

65
Case 4 Middle of the Road
  • PRINCE (PRavastatin INflammation/Crp Evaluation
    trial JAMA 200128664-70. And other trials have
    proven that Statins lower CRP 15-25 within 6
    weeks of initiation.
  • Weight loss, exercise and smoking cessation also
    lower CRP.

66
Case 4 Middle of the Road
  • CARE AFCAPS/TEXCAPS both suggest that the
    benefit of statin therapy among those with low
    LDL but high CRP may be as large as those with
    overt hyperlipidemia.
  • How to answer this ?
  • 2003 15,000 patients with LDLlt130 but CRP above
    2.0mg/l (JUPITER). All will be put on CRESTOR
    for prevention. What will happen?

67
Case 4 Middle of the Road
  • What does this mean for our patient?
  • CRP is most useful in those judged at
    intermediate risk and in primary prevention.
  • Review 45 yr old woman with an LDLlt130 but FHX
    and other borderline riskseg a 5 Framingham
    risk
  • HOW about checking an hs-CRP to further assess
    her risk ?

68
Case 4 Middle of the Road
  • CRP 3.2mg/l HIGH risk
  • Studies have proven she is in fact at risk more
    than her LDL would tell us. What to do?
  • Smoking cessation will lower CRP
  • Statins will lower her CRP
  • But, no prospective proof that this will change
    her outcome. It is your call, Doctor!

69
Other Novel Risk Factors
  • EBCT (coronary Ca score)
  • Lp (a) lipoprotein, Apo B, LDL particle size
  • Homocysteine
  • Plasma Adiponectin

70
EBCT/Coronary Ca scores
  • Coronary Ca occurs due to ASCVD
  • Normal score0-10 11-100 mild disease, 101-400
    non-obstructive disease, gt400 obstructive
  • Significant false positives and poor data in
    women and younger patients
  • It may not provide incremental information above
    that obtained with conventional risk factor
    assessment it is an alternative.

71
EBCT
  • Like with hs-CRP, it is not very useful in low
    risk or very high risk patients. It significantly
    correlates w/ cheaper hs-CRP.
  • Best used in intermediate risk folks where it
    might change treatment approach.
  • In patients w/ intermediate risk an EBCT score
    gt80 has a sensitivity of 85 and a specificity of
    75 for the risk of events.

72
EBCT/Coronary Ca Scores
  • USPSTF Feb 2004 D recommendation for adults
    at low risk. absence of evidence that detection
    ultimately results in improved health outcomes,
    and because false positive tests are likely to
    cause harm
  • I recommendation for those at high risk

73
Homocysteine
  • High plasma homocysteine may be directly related
    to atherosclerosis development.
  • Homocysteine may enhance inflammation
    thrombosis.
  • There may be no causal association between
    elevated homocysteine and CV disease risk.
  • New Evidence!!

74
Homocysteine
  • NEJM 13 April 2006 2 studies re homocysteine
    lowering
  • 1 Secondary prevention 5522 patients placebo
    vs 2,5mg FolateB6B12 did not reduce the risk
    of cardiovascular event, more pts in Tx had
    unstable angina.
  • 2 3749 pts post-MI treatment with B-vitamins
    did not lower risk of recurrent CV disease. A
    harmful effect of B-vitamin Tx was suggested.

75
Lipid Sub-fractions other markers
  • Lipoprotein a, Apolipoprotein B, LDL particle
    size
  • All have predictive value for CHD, indeed LDL
    particle size is more precise than LDL alone. But
    not widely available, expensive, less
    reproducible and still no outcome studies.

76
Case 5 The Unreachable Goal
  • 60 yr old male returns to see you 3 months after
    a 4vCABG. He feels great. At his last visit
    with his CT surgeon he was told follow-up with
    your family doctor to get your cholesterol in
    control
  • PMHX HTN x 20 yrs, BPH, ED, mild OA
  • MEDS ASA, Metoprolol 50 mg po bid, Viagra,
  • Simvastatin 20 mg po qd
  • FHX F with CVA at 68

Case 5 The Unreachable Goal
  • PE 70 160lbs P60 BP124/76
  • Cor RRR, no m/r/g, no jvd, healed median
    sternotomy scar
  • Ext no edema
    Lungs slight dec. breath sounds
  • TC180, HDL42 TG100 LDL118

78
Case 5 The Unreachable Goal
  • Risk Assessment he has CHD 2 prev.
  • Goal LDL is lt100 per ATP III (lt70-80 TNT trial
    data and ATP update)
  • At this level atherogenesis seems to arrest
  • At an LDL of 80 in mammalian species
    atherogenesis reverses. Also the PROVE-IT trial
    shows that an LDL of 62 was superior to an LDL of
    95.

79
Case 5 The Unreachable Goal
  • You decide to increase the simvastatin to 40mg po
    qd.
  • 6 weeks later TC 170 TG105 HDL42 LDL107
  • What do you do?

80
Case 5 The Unreachable Goal
  • Many options 1)increase simvastatin to 80 mg or
    change to atorvastatin or rosuvastatin.
  • PROBLEM inc risk of side effects and less LDL
    lowering effect as you inc statin doses. For
    every doubling of dose, LDL decreases by only 6
    . A threefold higher dose by 12 and a fourfold
    increase lowers LDL cholesterol by only 18.

81
Case 5 The Unreachable Goal
  • 2.) Add Ezetimibe 10 mg po qd less chance of
    side effects should help to reach goal LDL
    easily.
  • 3.) Intensify diet Ornish Plan add soluble
    fiber, add soy, add omega-3 fatty acids.
  • 4.) Be satisfied and await more trials

82
Summary
  • 8 Points to make you strong
  • 1) 1 2 prevention of
  • ASCVD are possible!
  • 2) NCEP/ATP III at
  • www.nhlbi.nih.gov is useful.
  • 3) The key step is risk assessment then
    tailoring treatment to individual risk.

83
Summary 8 Points
  • 3) Better medication options are a help
    Ezetimibe, Advicor, new statins and a cleaner
    understanding of statin side effects
  • 4)Attack the metabolic syndrome!! A multi-modal
    treatment plan is best.
  • 5) Dont ignore a chance for prevention because
    your patient is gt70 or lt35.

84
Summary 8 Points
  • 6) hs-CRP is a powerful new tool to predict risk
    especially in those at intermediate risk.
  • But, we need prospective proof that lowering
    it will help reduce ASCVD endpoints.
  • 7) Try to get to goal anticipate new ATP-IV
    guidelines.
