OBJECTIVE
The aim of this study was to investigate the relationship between oxidative/antioxidative stress markers and the diagnosis and complexity of coronary artery disease (CAD) in patients with stable CAD.

METHODS
A total of 145 patients were enrolled in the study. Based on coronary angiography results, the patients were categorized into 2 groups: those without CAD (Group 1) and those with CAD (Group 2). The patients in Group 2 were also categorized into low score and moderate/high score groups according to their SYNTAX score. The serum malondialdehyde (MDA) and total antioxidant capacity (TAOC) levels of Group 1 and Group 2 were compared. Finally, MDA and TAOC levels were compared between the moderate/high-risk and low-risk groups formed according to SYNTAX score.

RESULTS
There was a significant difference with respect to both serum TAOC and MDA levels between Group 1 and Group 2 (p=0.036 and p=0.029, respectively). The groups with a SYNTAX score 1-22 and with a SYNTAX score >22 were not significantly different with respect to serum TAOC or MDA level (p=0.582 and p=0.85, respectively).

CONCLUSION
The serum MDA level was significantly higher and the TAOC level was significantly lower in patients with stable CAD compared to those without; however, these molecule levels failed to predict disease complexity in patients with stable CAD.
