1. A method of determining whether a subject with elevated concentrations of very large high density lipoprotein (HDL) particles (HDL-P) is at increased risk for a cardiac event and/or CHD, comprising:
- providing a blood plasma or serum sample from the subject;
obtaining NMR signal data of the blood plasma or serum sample from the subject;
determining NMR derived concentration measurements of at least HPVS, HPML, and HPVL, where HPVS is a concentration of very small HDL-P subclasses, HPML is a concentration of medium and large HDL-P subclasses, and HPVL is a concentration of very large HDL-P subclasses;
identifying when a subject has an elevated concentration of HPVL relative to a population norm, wherein the subject has an elevated concentration of HPVL when the subject'"'"'s concentration is ≥
80% of a population norm; and
calculating at least one HDL interaction risk parameter associated with HDL content of a blood plasma or serum sample of the subject, the at least one HDL interaction risk parameter comprising at least two of HPVS, HPML, and HPVL.
