Are oxidative stress markers helpful for diagnosing the disease and determining its complexity or extent in patients with stable coronary artery disease?

Area of Science:

• Cardiology
• Biochemistry
• Oxidative Stress Research

Background:

• Coronary artery disease (CAD) is a significant health concern.
• Oxidative and antioxidative stress markers are implicated in various cardiovascular conditions.
• Understanding these markers' role in CAD diagnosis and complexity is crucial.

Purpose of the Study:

• To investigate the relationship between oxidative/antioxidative stress markers and the diagnosis of coronary artery disease (CAD).
• To explore the association between these markers and the complexity of CAD in patients with stable CAD.

Main Methods:

• 145 patients were categorized into non-CAD and CAD groups based on coronary angiography.
• Patients with CAD were further stratified by SYNTAX score into low and moderate/high complexity groups.
• Serum malondialdehyde (MDA) and total antioxidant capacity (TAOC) levels were measured and compared between groups.

Main Results:

• Significantly higher serum MDA and lower TAOC levels were observed in patients with CAD compared to those without (p=0.036 and p=0.029).
• No significant differences in MDA or TAOC levels were found between low and moderate/high complexity CAD groups (p=0.582 and p=0.85).

Conclusions:

• Serum MDA and TAOC levels can differentiate patients with stable CAD from those without.
• These oxidative/antioxidative stress markers do not appear to predict the complexity of coronary artery disease in stable patients.
