This diet-induced model mimics human atherosclerotic clinical conditions such as atherosclerotic lesions, increased risk of cardiovascular events and plaque formation.

Correlations between metabolic activity, inflammation, lymphocyte infiltration and vulnerable plaque markers were observed in the carotids and aortic arch, similar to the clinical setting.

This translational model is thus designed to test the efficacy of anti-atherosclerotic drugs and of biomarkers for risk stratification of the patients.
