    Abstract

    Inflammation is an important element in the development and destabilization of atherosclerotic plaque. Using a high sensitivity multiplex assay, previously untested in the context of atherosclerotic disease, we determined serum concentrations of GM-CSF, IFNgamma, IL-1beta, IL-2, IL-10, IL-12p70, TNF alpha, IL-6, and IL-8 in 48 Myocardial Infarction (MI) patients, 14 Unstable Angina (UA) patients and 12 healthy controls. IFNgamma levels were significantly higher in MI compared to UA (p=0.0091) and Control groups (p=0.0014). IL-10 also showed higher expression levels between MI, UA groups and Controls (p=0.0299).This up-regulation may reflect the extent of plaque instability and/or rupture in MI patients.Our observations provide evidence that IFNgamma and IL-10 merit further investigation in atherosclerotic disease states as potential markers of disease and therapeutic targets.
