OBJECTIVE: Considering the knowledge gap between underlying pathophysiological mechanisms of oxidative stress and increased cardiovascular risk, the present study aimed to examine the potential relationship between total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) and the Reynolds Risk Score (RRS) in the cohort of postmenopausal women.

PATIENTS AND METHODS: A total of 126 postmenopausal women participated in this cross-sectional study. Blood pressure, anthropometric and biochemical markers were determined. OSI was calculated as the TOS/TAS ratio. Associations of biochemical parameters with RRS were tested using univariable and multivariable logistic ordinal regression analysis.

RESULTS: TOS and OSI were the highest in women in high RRS category compared to moderate and low risk ones (p<0.001, for both). There was no difference in TAS level across RRS categories (p=0.370). Multivariable ordinal regression analysis showed independent association of TOS and OSI with RRS when tested with other clinical variables [OR=2.45; 95% CI (1.08-5.53); p=0.031 and OR=2.84; 95% CI (1.27-6.36); p=0.011, respectively].

CONCLUSIONS: TOS and OSI are associated with the RRS in the cohort of postmenopausal women. Longitudinal studies are needed to confirm whether adding the TOS and OSI to the standard RRS algorithm could improve its potential to predict cardiovascular event.
