The aim of this randomized double-blind study was to evaluate the effect of oral zinc and selenium supplementation on oxidative stress and inflammation biomarkers as well as the status of zinc and selenium in patients with atherosclerosis and angina stable treated with rosuvastatin. The hypotheses tested in this study were: Treatment with rosuvastatin impairs zinc and selenium status in patients with atherosclerosis and stable angina? Zinc and selenium supplementation, concomitantly with rosuvastatin, influences the antioxidant and anti-inflammatory as well as the status of minerals?
The study included 47 men and 29 women, average age around 60 years, with coronary atherosclerosis diagnosed by angiography. Data from patients were obtained at beginning and after four months of treatment with 10 mg rosuvastatin, concomitantly with zinc (30mg/d) and selenium (150μg/d) supplementation or placebo. The anthropometric and dietary data, zinc and selenium concentrations in plasma and erythrocyte, lipid profile, electronegative LDL (LDL(-)), anti- electronegative LDL, Ac-LDL(-) immune complexes, GPx and SOD activities, IL-6 and hs-CRP were evaluated in all patients.

Change from baseline in zinc and selenium status at 4 months
We evaluated the effects of 10mg rosuvastatin treatment as well as the effect of treatment with 10 mg rosuvastatin, concomitantly with zinc (30mg/d) and selenium (150μg/d) supplementation on plasma zinc and selenium and on erythrocyte zinc and selenium.
Time frame: Baseline and 4 months
Change from baseline in lipid profile at 4 months
We evaluated the effects of 10mg rosuvastatin treatment as well as the effect of treatment with 10 mg rosuvastatin, concomitantly with zinc (30mg/d) and selenium (150μg/d) supplementation on total cholesterol, LDL, non-HDL cholesterol and, triglycerides.
Time frame: Baseline and 4 months
