  • Transcript of "2008.02.12 Massie Hyperlipidemia"

    1. 1. Stanford Massie M.D. GIM Noon Conference February 12, 2008
    2. 2. Objectives By the end of this session, participants should: <ul><li>Recall the recommendations for treatment of cholesterol in the 2004 update to the NCEP/ATP III guidelines </li></ul><ul><li>Recognize and recall the key findings of several important studies since 2004 </li></ul><ul><ul><li>Focus on Lipid measurement, CV risk prediction and Secondary Prevention </li></ul></ul><ul><li>Appreciate emerging trends in “lipidology” </li></ul><ul><li>Apply these insights to the care of patients </li></ul>
    3. 3. The scope of the problem <ul><li>Dyslipidemia affects 1 in 2 Americans </li></ul><ul><li>It is a major RF for CVD, CV death and all cause mortality </li></ul><ul><li>Large observational studies suggest a strong graded relationship between increasing LDL and CAD events. </li></ul><ul><li>Management of dyslipidemia can markedly alter CV morbidity/mortality </li></ul>Ann Intern Med. 2007; ITC-9:1-16.
    4. 4. The scope of the problem-2 <ul><li>Dyslipidemia requiring drug treatment is prevalent in nearly 30% of patients without clinical CV disease </li></ul><ul><li>Of these, only half are taking lipid lowering medication </li></ul><ul><li>Benefits of statins are only realized when pts. take them >80% of time </li></ul><ul><li>6 months after initiation of statin therapy, adherence rates are 40-65% </li></ul>Circulation 2006;113:647-656.
    5. 5. JACC 2004;44:720-32
    6. 6. 2004 Update to NCEP/ATP III <ul><li>Review of 5 major statin trials with implications for therapy: </li></ul><ul><ul><li>Heart Protection Study </li></ul></ul><ul><ul><li>PROSPER </li></ul></ul><ul><ul><li>ALLHAT-LLT </li></ul></ul><ul><ul><li>ASCOT-LLA </li></ul></ul><ul><ul><li>PROVE IT-TIMI 22 </li></ul></ul>
    7. 7. JACC 2004;44:720-32 <ul><li>Very high risk= established CVD + </li></ul><ul><li>Major risk factors (especially DM) </li></ul><ul><li>Severe and poorly controlled risk factors (especially continued smoking) </li></ul><ul><li>Multiple RFs of the metabolic syndrome </li></ul><ul><li>Acute coronary syndromes </li></ul>
    8. 8. Log-Linear relationship of LDL and CHD risk JACC 2004;44:720-32
    9. 9. Ann Intern Med. 2006;145:520-530.
    10. 10. Diminishing returns of the hypothesized log-linear relationship Ann Intern Med. 2006;145:520-530.
    11. 11. Today’s clinic <ul><li>Patient 1: Healthy 40 y.o. male </li></ul><ul><li>Patient 2: 57 y.o. male with stable CAD </li></ul><ul><li>Patient 3: 65 y.o. female with recent stroke here for follow up </li></ul>
    12. 12. Road Map <ul><li>Lipid Measurements </li></ul><ul><li>CVD risk prediction </li></ul><ul><li>Secondary Prevention (select groups) </li></ul><ul><ul><li>CHD </li></ul></ul><ul><ul><li>Stroke </li></ul></ul><ul><ul><li>ESRD </li></ul></ul><ul><ul><li>Diabetes </li></ul></ul><ul><li>Future Directions </li></ul>
    13. 13. Patient 1 <ul><li>40 y.o. white male here because </li></ul><ul><li>“ One of my coworkers who is my age just dropped dead from a heart attack. I want you to check me and make sure I’m not going to do the same thing.” </li></ul><ul><li>“ My insurance is good, I want the best cholesterol test there is” </li></ul>
    14. 14. Focus Questions for Patient 1 <ul><li>Which lipid test should you order? </li></ul><ul><li>What is the best way to predict his CV risk? </li></ul>
    15. 15. Clinical Utility of Different Lipid Measures for Prediction of Coronary Heart Disease in Men and Women JAMA. 2007;298(7):776-785
    16. 16. Background <ul><li>ApoB 100 is included in all atherogenic particles (VLDL, IDL, LDL, LP(a)) </li></ul><ul><li>Higher ApoB levels and lower Apo A-I levels linked with pathogenesis of CHD </li></ul><ul><li>Some reports suggest these markers may be superior for CHD risk prediction </li></ul><ul><ul><li>LDL not all the same </li></ul></ul><ul><ul><li>Apo B levels may better reflect the number of atherogenic particles in plasma </li></ul></ul>JAMA. 2007;298(7):776-785
    17. 17. Study design <ul><li>Population based, prospective cohort </li></ul><ul><li>3322 middle aged white participants in Framingham offspring study </li></ul><ul><ul><li>Without known CV disease </li></ul></ul><ul><li>Outcome: incidence of first CHD event </li></ul><ul><li>Measure: Complex analyses to compare several different lipid measures for ability to predict CHD events </li></ul>
    18. 18. Results <ul><li>Ratios are superior to individual lipids </li></ul><ul><ul><li>Chol:HDL vs. ApoB: ApoA-I </li></ul></ul><ul><li>ApoB:ApoA-I ratio </li></ul><ul><ul><li>Performed well, but not significantly better than other lipid measures </li></ul></ul><ul><ul><li>“ Did not provide incremental value for CHD risk prediction over established risk factors, including Chol:HDL.” </li></ul></ul>
    19. 19. Implications <ul><li>Head to head, Chol:HDL and ApoB/ApoA-1 ratios are comparable </li></ul><ul><li>Further knowledge of ApoB/ApoA-1 does not seem to improve ability to predict CHD risk </li></ul><ul><li>Suggests routine measurement of apoliproteins in clinical practice is not necessary </li></ul>
    20. 20. General Cardiovascular Risk Profile for Use in Primary Care The Framingham Heart Study <ul><li>Ralph B. D’Agostino, Sr, PhD; Ramachandran S. Vasan, MD; Michael J. Pencina, PhD; Philip A.

    21. 21. Background <ul><li>Framingham risk score effective, but only predicts CHD risk (not stroke etc.) </li></ul><ul><li>CV diseases share common risk factors </li></ul><ul><li>Set out to develop a way to predict risk for all CVD events </li></ul>JAMA. 2007;298(7):776-785
    22. 22. Study design <ul><li>8491Framingham study participants </li></ul><ul><ul><li>Without known CV disease </li></ul></ul><ul><li>Outcome: incidence of first CHD event </li></ul><ul><li>Derived CVD prediction algorithm and compared with disease specific prediction tools </li></ul>Circulation. 2008;117: 743-753.
    23. 23. Results <ul><li>General CV risk prediction algorithm performed as well as individual disease specific multivariable risk predictions </li></ul><ul><li>It builds on prior models by: </li></ul><ul><ul><li>Adding HDL </li></ul></ul><ul><ul><li>Being based on study with more events </li></ul></ul><ul><ul><li>Estimating absolute CV risk </li></ul></ul><ul><li>It is simple to use, will be provided in electronic forms once validated </li></ul>Circulation. 2008;117: 743-753.
    24. 24. Implications <ul><li>A new tool for CVD risk prediction now available </li></ul><ul><li>Allows prediction of all CV events </li></ul><ul><ul><li>Stroke, CAD, PVD, CHF </li></ul></ul><ul><li>Designed for use in primary care </li></ul><ul><li>Needs validation </li></ul>Circulation. 2008;117: 743-753.

He does not have Diabetes. </li></ul><ul><li>He takes Simvastatin 10 mg daily for his cholesterol and his LDL is 105. </li></ul><ul><li>He is here for routine f/u. </li></ul>
    28. 28. Focus Questions for Patient 2 <ul><li>Is he on an adequate dose of statin? </li></ul><ul><li>What should his target LDL be? </li></ul>

(2007) 1, 182–190 TNT: If results extrapolated to clinical practice, use of 80 mg atorvastatin to reduce LDL from 101 to 77 in 1000 pts with stable CAD would prevent 34 CV events over a period of 5 years. NNT to prevent one event~30.
