Cholesterol and Lipid Disorders

Call for an Appointment 855-855-6484

Duke cardiologists, endocrinologists, and lipid specialists manage and treat a full range of lipid disorders, including abnormalities in cholesterol, fat, triglycerides (dyslipidemia), and other lipid levels (hyperlipidemia). Our providers treat complex lipid disorders and help determine treatment alternatives for people who cannot take statins, the most common cholesterol-lowering medication. Our goal is to help you manage your lipid disorder, avoid complications, and lead a healthier, fuller life.

Cholesterol and Lipid Disorder Tests

We offer advanced screening and diagnostic services, which are important if you have a family history of lipid disorders, or if you or a family member have been diagnosed with heart disease early in life. Early screening and detection help your doctors develop a preventive plan to better manage risks to your health.

Blood Tests

In addition to a traditional cholesterol blood test, the following blood tests may be ordered to provide more information about your risk of heart disease, stroke, and vascular disease:

  • Lipoprotein(a)
  • High-sensitivity C-reactive protein (hs-CRP)
  • Nuclear magnetic resonance (NMR) LipoProfile
  • Apolipoprotein (B)

Lower-Extremity Ultrasound and Ankle Brachial Index

A lower-extremity ultrasound uses sound waves to create images of the blood vessels inside your legs, whereas an ankle brachial index measures blood pressure in your legs. Together these tests, which are administered at the same time, assess the strength of blood flow in your lower extremities to evaluate for peripheral artery disease.

Carotid Artery Ultrasound

This specialized ultrasound measures the thickness of the inner two layers of your carotid artery, an important blood vessel in the neck that supplies blood to the brain. This test can help diagnose carotid artery disease and determine your risk for coronary heart disease, which is often caused by abnormal lipoprotein levels or a family history of lipid disorders.

Coronary Calcium Scan

This low-dose CT scan generates images of your coronary arteries, which surround the heart. It helps identify calcium deposits from cholesterol plaque buildup within the coronary arteries. Doctors use this information to calculate a coronary calcium score, which can help predict your risk for heart disease in the future and help determine whether treatment is needed.

Coronary CT Angiography

This specialized CT scan uses contrast dye to identify cholesterol plaque buildup in the coronary arteries and help determine the best treatment regimen to reduce cardiovascular risk.

Treatment: Lifestyle Changes

Reducing Risk
An important part of your treatment plan is reducing your risk for heart attack and stroke. Depending on your medical history, we may recommend a smoking cessation program or diabetes management classes.

Dietary Counseling
Managing a lipid disorder is foundational to treating high cholesterol. This often requires dietary changes. Our doctors, dietitians, nurse practitioners, and physician assistants work with you to improve your diet and eating habits. This approach can help you successfully control your cholesterol and fat levels.

Low Glycemic Diet
Sometimes initial changes to your food choices aren’t enough. A diet that emphasizes low-glycemic (carbohydrate) foods and focuses on stabilizing blood sugar levels can lead to a healthier metabolism and weight loss. An example of this type of diet was developed at the Duke Lipid Clinic, where a team of doctors from across Duke specializes in lipid management.


Treatment: Medications

Your provider may recommend one or more medications to successfully treat high cholesterol and lipid disorders. We consider your overall health, lifestyle, and other factors to recommend a medication regimen that works for you and avoids unwanted side effects.

Statins
This common medication comes in a pill form. It lowers cholesterol by blocking the substance that your body needs to produce cholesterol and helps decrease the buildup of plaque in your arteries. Statins can reduce your risk of heart attack or stroke by up to 50%. You may not be able to take statins if you have kidney or liver disease, hypothyroidism, or other conditions, or if you experience side effects like muscle pain.

Ezetimibe
This common medication also comes in a pill form. It blocks the absorption of cholesterol from the intestines into the bloodstream. Ezetimibe can be taken along with statin therapy if needed. 

PCSK9 Inhibitors 
These medications may be recommended if your body cannot tolerate statins or if you need additional treatment to lower your cholesterol, especially if you have a history of heart disease or a genetic cholesterol condition. PCSK9 inhibitors are given as injections either every two weeks or every six months. They can lower “bad” cholesterol by at least 50%.

Bempedoic Acid 
This medication is typically used in addition to statins when more cholesterol-lowering is needed in people with heart disease or genetic cholesterol disorders.

Evinacumab 
This is an injectable medication taken every four weeks for people with difficult-to-control genetic cholesterol disorders.

Omega-3 Fatty Acids
Prescription-strength omega-3 fatty acids can help lower triglycerides (a type of fat in the blood). One type called icosapent ethyl has been shown to also reduce cardiovascular events in people at high risk.

Fibrates
This is a pill that can lower triglycerides by up to 60% and can help reduce the risk of pancreatitis due to triglycerides.

Niacin
This is a pill that can help lower triglycerides in people who need additional lowering.

Olezarsen
This is an injectable medication given every four weeks to help reduce triglycerides in people with genetic triglyceride disorders or who are not responding to other triglyceride-lowering treatments.

Why Choose Duke

Expertise When You Need It
Almost half of our patients come to us because they can’t get treatment elsewhere for statin intolerance. We specialize in developing alternatives for you and have led research to find new strategies for lowering low-density lipoproteins, also known as “bad” cholesterol.

Many medications are effective at treating lipid disorders, but some people prefer not to take daily medication or may experience side effects. We’ll work with you to develop the most effective treatment possible that fits your lifestyle and preferences.

Advancing Lipid Disorder Research
Experts in our Duke Lipid Clinic and Duke Cardiometabolic Clinic research new ways to advance management of lipid disorders. This work allows our doctors to identify new ways to approach disease and gain access to the most advanced treatments.
