Advanced lipid profile lab testing, which includes measurements of apolipoprotein B (apoB) and LDL particle number, can provide important information about an individual’s cardiovascular health beyond what is typically measured in a standard lipid panel. Let’s explore the research supporting the use of advanced lipid profile testing and what these tests can tell us about cardiovascular disease risk.
What is the Standard Lipid Panel?
A standard lipid panel typically includes measurements of total cholesterol, LDL cholesterol (often referred to as “bad” cholesterol), HDL cholesterol (often referred to as “good” cholesterol), and triglycerides. These measurements can provide useful information about an individual’s overall cardiovascular health, but they do not always tell the whole story.
For example, it is possible for an individual to have normal levels of LDL cholesterol but still be at increased risk for cardiovascular disease if they have a high number of small, dense LDL particles. On the other hand, an individual with high levels of HDL cholesterol may not necessarily have a lower risk of cardiovascular disease if their HDL particles are not functioning properly.
Advanced Lipid Panel: Apolipoprotein B
This is where advanced lipid profile testing comes in. Let’s review two important measurements that are included in advanced lipid profile testing: apolipoprotein B and LDL particle number.
Apolipoprotein B is a protein that is found on the surface of LDL particles, and it plays an important role in the transport of cholesterol and other lipids throughout the body. Measurement of apoB can provide a more accurate reflection of LDL particle number than measuring LDL cholesterol alone. In fact, some studies have suggested that apoB may be a better predictor of cardiovascular disease risk than LDL cholesterol.
Advanced Lipid Panel: LDL Particle Number
LDL particle number, also known as LDL-P, is a measurement of the number of LDL particles in the blood. This measurement can provide important information about an individual’s cardiovascular disease risk. It is the number of LDL particles, rather than just the amount of cholesterol carried by these particles, that is thought to be most important in the development of atherosclerosis. Atherosclerosis is a disease in which fatty plaques are deposited on the inner walls of your arteries.
What does the research say?
So, what does the research say about the use of apoB and LDL particle number in advanced lipid profile testing? A number of studies have demonstrated that these measurements can provide valuable information about an individual’s cardiovascular disease risk above and beyond what is provided by a standard lipid panel.
For example, a study published in the Journal of the American College of Cardiology in 2017 found that measurement of apoB was a stronger predictor of cardiovascular disease risk than measurement of LDL cholesterol in a population of individuals with a family history of premature cardiovascular disease.
Similarly, a study published in the Journal of Clinical Lipidology in 2016 found that measurement of LDL particle number was a better predictor of cardiovascular disease risk than measurement of LDL cholesterol in a population of individuals with type 2 diabetes.
overall,
The research supports the use of advanced lipid profile testing, including measurement of apoB and LDL particle number, in the assessment of cardiovascular disease risk.
