LDL Particle Concentration NMR, Plasma [A Test in Focus]

ldlp-brochureTo offer a more complete picture of cardiovascular disease (CVD) risk, Mayo Medical Laboratories is now performing nuclear magnetic resonance (NMR) lipoprotein testing using Liposcience’s Vantera® Clinical Analyzer.

The Vantera Clinical Analyzer can identify and quantify concentrations of lipoproteins using NMR spectroscopy and proprietary signal processing algorithms. This analysis provides physicians and patients with a detailed assessment of CVD risk from a single blood test that measures the concentration of LDL-P and other lipoprotein information. LDL-P may assist in determining treatment strategies and clinical decision making for personalized LDL management.

  • Low-density lipoprotein cholesterol (LDL-C) remains the primary focus for cardiovascular risk assessment and evaluation of pharmacologic effectiveness based on treatment target goals.
  • Measurement of LDL-C may not accurately reflect the true burden of atherogenic LDL particles.
  • The total LDL particle concentration (LDL-P) is a measure of the total number of atherogenic particles, whereas LDL-C is only an estimate of the cholesterol contained within LDL particles.
  • LDL-P may aid in determining treatment strategies and clinical decision making for personalized LDL management.

Additional Information/Resources

Who should be tested?

LDL-P by NMR is appropriate for patients being managed with a lipid-lowering therapy, intensive lifestyle management, or who meet at least 1 of the following criteria1:

  • Known cardiovascular disease
  • Coronary heart disease risk equivalents, such as type 2 diabetes mellitus or chronic kidney disease
  • Multiple cardiometabolic risk factors that define metabolic syndrome:
    • High blood pressure or on antihypertensive medication
    • High blood sugar
    • High triglycerides
    • Low high-density lipoprotein cholesterol (HDL-C)
    • Abdominal obesity

What’s the relationship of LDL-P to cardiovascular disease?

Historically, clinicians have determined a patient’s risk for cardiovascular disease by measuring lipids such as LDL-C, HDL-C, and triglycerides. More recently, it’s been shown that measurement of lipoprotein particles, the containers that carry cholesterol, may be beneficial for patient management.

Among patients at risk for cardiovascular disease, about one-half have high LDL-P despite optimal levels of LDL-C2,3. For these patients, measuring and lowering LDL-P should be considered a primary goal of therapy due to its stronger association with cardiovascular risk.
