Abstract

Biomarkers have the potential to improve the clinical management of patients with AAA. A prospective, proteomics discovery study was undertaken to compare patients with AAA (n = 20) to matched screened controls (n = 19) for plasma protein expression. Surface-Enhanced-Laser-Desorption-Ionization Time of Flight Mass Spectrometry (SELDI ToF MS) coupled with Artificial Neural Networks (ANN) analysis identified six protein related diagnostic biomarker ions with a combined AUC of 0.89. This study discovered a signature plasma protein profile for patients with AAA and demonstrated that mass spectrometric based research for disease specific biomarker of AAA is feasible.
