[Ferritin, oxidative stress and coronary atherosclerosis].

Abstract In the recent years several studies showed the association between body iron stores, represented by serum ferritin, and atherosclerosis. It was proposed that iron bound to ferritin catalyzes the formation of highly reactive forms of oxygen free radicals which subsequently cause the oxidative modification of atherogenic lipoproteins. Aim of our study was to compare serum ferritin concentrations and certain markers of oxidative stress in patients with and without coronarographically assessed coronary vascular disease. Measurements were performed in 216 subjects at the age of 35-60 years. The patient group included 76 patients with coronarographically assessed coronary vascular disease (CVD) (mean age 51.16 +/- 5.713 years) and 140 healthy controls (mean age 50.21 +/- 5.331 years). The plasma concentration of ferritin was higher in patients (169.04 +/- 63.899 micrograms/l) than controls (87.70 +/- 41.394 micrograms/l), p
