Cholesterol and Lipids TIPS Wokefield Park 15/5/2013 Just a few questions! What is the NDA target for total cholesterol and LDL cholesterol? What are the QOF targets for cholesterol? What is the ideal time to take a statin and why? Name the most serious side effect of statins. What blood test would you order if you suspected it? Name another side effect of statins. All statins increase HDL cholesterol – true or false? What is the most typical lipid profile for type 2 diabetes? What is the most typical lipid profile for type 1 diabetes? R77 Statins & Ezetimibe For a person who is 40 yrs+ • Simvastatin (to 40 mg) unless CVS risk from non-hyperglycaemia-related factors is low (see R72) R72 Consider a person to be at high CVS risk unless…… • Not overweight • Normotensive • No microalbuminuria • Non-smoker • No high risk lipid profile • No h/o CVS disease • No FH of CVS disease If low CVS risk………… • Assess CVS risk using UKPDS risk engine • Start simvastatin if CVS risk > 20% over 10 yrs Once on a statin……….. • Repeat lipid profile in 1-3 months then annually • If total cholesterol>4.0 or LDL cholesterol >2.0 mmol/L titrate simvastatin to 80 mg daily Consider intensifying if……. • Existing/newly diagnosed CVS disease • Choose different statin/ezetimibe If h/o raised triglycerides……. • Consider secondary causes • Full lipid profile • Prescribe fenofibrate if Tg remain > 4.5 mmol/L • If Tg remain > 2.3 mmol/L consider adding fenofibrate to statin Kaplan–Meier Estimates of the Incidence of Outcome Events in the Total Study Population.

What ideally would you like the average baseline lipid profile to be? FIELD Study • 9795 participants • Type 2 diabetes • Age 50- 75 yrs • No prior statin/fibrate therapy • 2131 previous CVS disease • 7664 no known previous CVS disease FIELD - Recruitment Lipids • Total cholesterol 3-6.5 mmol/L + • Either TC:HDL cholesterol > 4 • Or triglycerides 1.0-5.0 mmol/L Original Article Effects of Combination Lipid Therapy in Type 2 Diabetes Mellitus The ACCORD Study Group N Engl J Med Volume 362(17):1563-1574 April 29, 2010 Lipid Values The ACCORD Study Group. N Engl J Med 2010;362:15631574 Kaplan-Meier Analyses of the Primary Outcome, Expanded Macrovascular Outcome, and Death The ACCORD Study Group. N Engl J Med 2010;362:15631574 Conclusion • The combination of fenofibrate and simvastatin did not reduce the rate of fatal cardiovascular events, nonfatal myocardial infarction, or nonfatal stroke, as compared with simvastatin alone • These results do not support the routine use of combination therapy with fenofibrate and simvastatin to reduce cardiovascular risk in the majority of high-risk patients with type 2 diabetes Baseline Characteristics of the Patients The ACCORD Study Group. N Engl J Med 2010;362:15631574 Conclusions Statins are safe, benefit many diabetics and almost all diabetics should be on them Treat total cholesterol & LDL cholesterol to target There is still a place for fibrates in combination and first line for those with HDL<1 and/or Tg>2.3
