Case Studies in Dyslipidemia: Implementing Evidence-based Strategies to Manage Patients

Program Description Dyslipidemia is a major risk factor for coronary heart disease (CHD), and its management is important in preventing the occurrence of cardiovascular events. Because many patients are unable to achieve their target lipid goals when treated with statin monotherapy, pharmacists need to be aware of the importance of combination therapy in controlling dyslipidemia. This program will briefly review therapeutic goals based on National Cholesterol Education Panel (NCEP) guidelines. Evidence supporting the rationale, efficacy, and safety data of combination therapy in patients with dyslipidemia will also be presented. Case studies will be used to demonstrate therapeutic strategies, goals, and challenges in managing patients with dyslipidemia. Special patient populations and challenges in identifying appropriate therapeutic goals will be discussed. Learning Objectives At the conclusion of this presentation, participants should be able to:

• Discuss therapeutic goals for managing dyslipidemia based on current NCEP guidelines.

• Identify the role and importance of LDL cholesterol, non-LDL parameters, and other factors in assessing cardiovascular risk.

• Given a summary of three specific patients with dyslipidemia, assess cardiovascular risk and lipid values and identify appropriate goals of therapy.

• Compare and contrast appropriate patient-specific treatment plans to treat dyslipidemia based on a cardiovascular risk assessment.

• Identify evidence to support treatment plans for patients with dyslipidemia.

Continuing Education Accreditation

Mark J. Cziraky, Pharm.D., FAHA Executive Vice President HealthCore, Inc. Wilmington, Delaware Dr. Mark Cziraky is Executive Vice President and co-founder of HealthCore Inc., a research organization based in Wilmington, Delaware. Prior to his current position, Dr. Cziraky was Assistant Professor at the Philadelphia College of Pharmacy and Science (PCPS) until 1997. He currently holds an Adjunct Associate Professor appointment at the University of Delaware School of Nursing. He is a graduate of PCPS, receiving both his Bachelor of Science and Doctor of Pharmacy degrees and attaining Summa Cum Laude honors for each degree. After receiving his graduate degree, he completed an ambulatory care residency at Blue Cross and Blue Shield of Delaware (BCBSDE). Dr. Cziraky has been extensively involved in clinical, health economic, and outcomes research for more than a decade with a clinical focus on cardiovascular diseases. While a faculty member at PCPS, Dr. Cziraky initiated a dyslipidemia management program at a large group practice within BCBSDE and eventually transformed it into a multidisciplinary cardiovascular risk-management program. This initiative was recognized by the Delaware Pharmacy Society and earned Dr. Cziraky the Delaware Innovative Pharmacy Practice Award in 1997. Additionally, he was recognized by his peers and American Druggist as one of the 50 Most Influential Pharmacists in 1998. In 1998, the American Heart Association awarded Dr. Cziraky with fellowship on the Council of Arteriosclerosis, Thrombosis and Vascular Biology. Dr. Cziraky was elected a member of the National Heart, Lung and Blood Institute’s (NHLBI) National High Blood Pressure Education Program Coordinating Committee in 2000 representing the American Pharmacists Association and was part of the writing committee for the Joint National Committee (JNC-7) Hypertension Management Guidelines. Additionally, he is currently the chairman of the National Committee on Quality Assurance’s (NCQA) Health Care Practitioner Advisory Committee and a member of the Board of Trustees of both the Institute of Safe Medication Practice and the Wellness Community of Delaware. He was elected to the board of directors of the Northeast Lipid Association, part of the National Lipid Association. Dr. Cziraky is currently a reviewer for numerous medical and pharmacy journals. He is a nationally recognized presenter on both cardiovascular and health economic-related topics and has published original research and book chapters in these same areas.

Facts, Cardiovascular Disease in the U.S.

• In 2002, accounted for 38.0% of all deaths or 1 of every 2.6 deaths

• CVD mortality was nearly 60% of “total mortality”

• Since 1900 CVD has been the No. 1 killer in every year but 1918 (influenza pandemic)

• Claims as many lives each year as the next 5 leading causes of death combined, including cancer

• 3,339 case reports of rhabdomyolysis with statinsfrom 1990 - 2 002; 38% were associated with concurrent fibrate therapy

• Statin/Fibrate:– Controlled clinical trials (n=600): 1% incidence of

CK > 3 x ULN, with no cases of rhabdomyolysis– Low to moderate dose statin with fibrate has a low risk

of myopathy– Interaction most problematic with gemfibrozil

• Statin/Niacin:– Lower risk for myopathy than statin/fibrate

JAMA 2003;289:1681-1690.J Am Col Cardiol 2002;40(3):568-579.

Risks of Statin Combination Therapy

Statin/Fibrate Interaction• Facts about gemfibrozil:

– Known to ↑ risk of rhabdomyolysis with statins– Inhibits hepatic glucuronidation of certain statins– Reduced maximum statin dose in combination:

• Lovastatin 20 mg daily• Rosuvastatin 10 mg daily• Simvastatin 10 mg daily

• Fenofibrate does not inhibit glucuronidation

JAMA 2003;289:1681-1690.

CASE #3:Pharmacotherapy Options

o non - HDL reduction– Higher potency

statin regimen– Add a nicotinic acid– Add a fibrate

o LDL - C reduction– Higher potency

statin regimen– Add ezetimibe– Add a bile acid

sequestrant– Add nicotinic acid

• Potential regimen modifications:
