Postoperative evaluation of interleukin-8 and C1q/TNF-related protein-12 in patients undergoing coronary artery bypass graft surgery.

OBJECTIVE: Coronary artery bypass graft surgery is one of the most frequently performed surgeries worldwide. Coronary artery bypass graft surgery induces an inflammatory response. Interleukin-8 is a pro-inflammatory cytokine that plays a role in the pathogenesis of cardiovascular diseases. C1q/TNF-related protein-12 is implicated in mitigating inflammation and cardiomyocyte damage. This study aimed to compare interleukin-8 and C1q/TNF-related protein-12 levels before and 45 days after coronary artery bypass graft surgery. METHODS: A total of 43 patients who underwent coronary artery bypass graft surgery were studied. Serum concentrations of interleukin-8 and C1q/TNF-related protein-12 were evaluated using the enzyme-linked immunosorbent assay method before and 45 days after the surgery. RESULTS: No significant differences were observed in interleukin-8 levels between pre- and post-coronary artery bypass graft surgery (p=0.077). However, serum levels of C1q/TNF-related protein-12 were found to be lower 45 days after coronary artery bypass graft surgery compared to pre-surgery levels (p<0.001). Moreover, changes in C1q/TNF-related protein-12 were not associated with diabetes, hypertension, and body mass index (p>0.05), but C1q/TNF-related protein-12 alterations were found to be associated with opium addiction. CONCLUSION: These findings suggest that the evaluation of C1q/TNF-related protein-12 can be beneficial for the late assessment of post-coronary artery bypass graft surgery inflammation. The reduction of C1q/TNF-related protein-12 levels might indicate increased levels of inflammation after surgery at this time point, which requires the assessment of further inflammatory factors to confirm this finding.
