This study explores the relationships betweenmarkers for lesion progression in arteriosclerosis production of radicals and clinical characteristics. Methods The radical production during carotid endarterectomy was studied in 13 patients with an ex vivo spin trap method using OXANOH as a spin trap. MCP-1 ICAM-1 MMP-9 and oxLDL were determined in venous blood samples before during and after clamping of the carotid artery. Principal component analysis PCA as well as partial least square regression analysis pLS was applied to interpret the data. Results PCA and PLS analysis revealed that high values of MMP-9 and low values of ICAM-1 were associated with high radical production whereas MCP-1 and oxLDL were not correlated to radical production. MMP-9 was elevated at diabetes high haemoglobin high leucocyte counts and thrombocyte counts as well as at .
