Objectives: It was known that oxidative/antioxidative balanceshifted to oxidative side in patients with coronaryartery disease. The aim of this study is to evaluate therelationship between coronary artery disease and totalantioxidant status, oxidative stress index.Materials and methods: The study group consisted of87 consecutive patients who were hospitalized for coronaryangiography. Plasma total oxidative status (TOS)and total antioxidative capacity (TAC) levels were measuredand oxidative stress index (OSI) was calculated.Results: The TAC values increased statistically significantin the four tertile compared with the first tertile (1.9± 0.2 vs 2.0 ± 0.2 mmol Trolox Eq/l) and the TOS valuesdecreased non- significantly in the four tertile ( 5.2 ± 2.8vs 7.2 ± 5.4 μmol H2O2 Eq/l) as compared to the patientsin the first tertile. According to the number of diseasedvessels, plasma oxidative characteristics did not differ betweenthe three groups.Conclusions: Plasma TAC levels increased in subjectswith coronary atherosclerosis and severity of coronaryatherosclerosis is related with TAC.
