  • Publication number: 20170083663
    Abstract: Methods, computer program products and apparatus determine a subject's risk of having or developing CHD using a calculated HDL particle risk number and/or a mathematical model of risk associated with HDL particles that adjusts concentrations of at least one of the subclasses of small, medium and large HDL particle measurements to reflect predicted CHD risk. A calculated LDL particle risk number may also be generated as well as a lipoprotein particle index derived from the ratio of RLDL/RHDL.

  • Publication number: 20170003269
    Abstract: Biomarkers and/or risk assessments identify patients having an increased risk of certain clinical disease states including, for example, CHD, type 2 diabetes, dementia, or all-cause death (ACD) using NMR signal to measure a level of “GlycA” in arbitrary units or in defined units (e.g., ?mol/L) that can be determined using a defined single peak region of proton NMR spectra. The GlycA measurement can be used as an inflammation biomarker for clinical disease states . The NMR signal for GlycA can include a fitting region of signal between about 2.080 ppm and 1.845 ppm of the proton NMR spectra.

  • Patent number: 9483611
    Abstract: Embodiments of the invention are directed to improved discrimination of protective (anti-atherogenic) HDL from atherogenic or non-protective (NP) HDL. The methods, systems and computer program products determine protective high density lipoprotein particle (HDL-P) numbers. The methods include obtaining concentration measurements of at least twenty subpopulations of HDL-P subclasses in a blood plasma or serum sample and calculating a protective HDL-P number using (i) a defined subset of the obtained HDL-P concentration measurements or (ii) a zero or defined weighting factor below 1 for HDL-P concentration measurements for HDL subclasses associated with particle sizes above about 11 nm.

  • Publication number: 20150127267
    Abstract: Methods, systems and circuits evaluate a subject's risk of developing type 2 diabetes using defined mathematical models of short term risk (STR) and longer term risk of progression. The evaluations can stratify risk for patients having the same glucose measurement, particularly those with intermediate or low (normal) fasting plasma glucose (FPG) values. The STR or IR (insulin resistance) model(s) may include an inflammatory biomarker such as an NMR derived measurements of GlycA and a plurality of selected lipoprotein components of at least one biosample of the subject. Embodiments of the invention also provide methods, systems and circuits that generate STR scores as a marker of beta-cell dysfunction or impairment.
