Abstract: The present disclosure provides methods, systems, and kits for quantifying lipoprotein(a) based on measuring selected proteotypic peptide(s). The methods of the disclosure are also useful in determining if a subject is at risk to develop cardiovascular disease. The disclosure also provides methods of determining a reference amount of selected proteotypic peptide(s) in a reference sample.

Abstract: The invention provides methods of screening a mammalian subject to determine if the subject is at risk to develop or is suffering from, cardiovascular disease. In one embodiment, the method comprises detecting a measurable feature of at least two biomarkers in an HDL subfraction, or in a complex containing apoA-I or apoA-III isolated from a biological sample obtained from the subject, wherein the at least two biomarkers are selected from the group consisting of apoA-I, apoA-II, apoB-100, Lp(a), apoC-I, and apoC-III, combinations or portions and/or derivatives thereof, and comparing the measurable features of the at least two biomarkers from the biological sample to a reference standard, wherein a difference in the measurable features of the at least two biomarkers from the biological sample and the reference standard is indicative of the presence or risk of cardiovascular disease in the subject.

Abstract: The invention provides methods of screening a mammalian subject to determine if the subject is at risk to develop, or is suffering from, cardiovascular disease. The methods comprise detecting an amount of at least one biomarker in a biological sample, or HDL subfraction thereof, from the subject, and comparing the detected amount of the biomarker to a predetermined value, where a difference between the detected amount and the predetermined value is indicative of the presence or risk of cardiovascular disease in the subject. In some embodiments, the biomarker comprises at least one of ApoC-IV, Paraoxonase 1, C3, C4, ApoA-IV, ApoE, ApoL1, C4B1, Histone H2A, ApoC-II, ApoM, Vitronectin, Haptoglobin-related protein, and Clusterin, or combinations thereof.
