  • Patent number: 8383355
    Abstract: The present invention related to a method of identifying a subject having or at risk of having or developing a cardiovascular disease and/or a cardiovascular event, comprising: —measuring, in a sample obtained from said subject, at least two cardiovascular risk factors: a) sPLA2 type HA mass and b) oxidized phospholipids on apolipoprotein B-IOO particles (OxPL/apoB), —combining said measurements, the combined value of sPLA2 type HA mass and OxPL/apoB being indicative of having or a risk of having or developing a cardiovascular disease and/or cardiovascular event.

  • Publication number: 20070122419
    Abstract: During the progression of atherosclerosis, autoantibodies are induced to epitopes of oxidized low-density lipoprotein (OxLDL), and active immunization of hypercholesterolemic mice with OxLDL ameliorates athero-genesis. The present studies have identified anti-OXLDL autoantibodies that share complete genetic and structural identity with antibodies produced by anti-phosphorylcholine B-cell clone, T15.

  • Publication number: 20060177435
    Abstract: The present invention relates to the analysis of oxidized phospholipids (OxPL) on apolipoprotein B-100 in patients at high risk or with documented coronary artery disease (CAD) or acute coronary syndromes (ACS) such as unstable angina and acute myocardial infarction or suspected of being at risk for ACS. Such methods are useful for diagnostic purposes and for monitoring the effects of dietary interventions or with drugs such as statins. More particularly, the present invention relates to methods for determining OxPL/apoB ratios as indices of atherosclerosis regression and plaque stability.
