The results of multiple comparisons among the three surgical subgroups showed that interleukin-8 levels in the aortic surgery group (median, 100 pg/mL; IQR, 32–196 pg/mL) tended to be higher than the valve surgery group (median, 49 pg/mL; IQR, 31–79 pg/mL) with near significance ( p = 0.065), and significantly higher than the OPCAB group (median, 35 pg/mL; IQR, 20–57 pg/mL) ( p = 0.001).
