Claim:
1. A method for identifying a biomarker peptide for diagnosing a cardiovascular disease, comprising: (a) obtaining a biological sample from a subject having or at risk of having a cardiovascular disease; (b) fractionating the biological sample to obtain an unbound fraction having the biomarker peptide free from albumin and immunoglobulin present in the biological sample and a bound fraction having the biomarker peptide bound to albumin or immunoglobulin present in the biological sample; and (c) determining an amount of the biomarker peptide in the unbound fraction, the bound fraction, or both the unbound fraction and the bound fraction, the biomarker peptide consisting of an amino acid sequence selected from the group consisting of SEQ ID NOS: 8-30.
