Study of prooxidant-antioxidant balance and some risk factors of coronary artery disease

There is evidence that oxidative stress can be considered as a critical event in the development of atherosclerotic complications. In this study, we aimed to assay the values of prooxidant-antioxidant balance (PAB) in patients with coronary artery disease (CAD), as a cardiovascular risk factor, and its relationship with some clinical, biochemical, and anthropometric parameters was examined.
In a case–control study, forty CAD patients and forty age and body mass index (BMI)-matched healthy controls hospitalized in the cardiology section of Imam Ali hospital of Zahedan, Iran, were enrolled. The levels of serum lipid profile, C-reactive protein (CRP), blood pressure, BMI, and waist circumference (WC) were evaluated. The values of PAB were also assayed simultaneously by photometric method, using 3, 3′, 5, 5′-tetramethylbenzidine and its cation, used as an indicator of redox.
PAB was found to be significantly higher in CAD patients (P The study shows that the PAB assay in conjunction with other risk factors can be used as an independent prognostic predictor of CAD, particularly in patients who need antioxidant therapy.
