Research has shown that higher levels of circulatory cytokines such as IL-6, IL-8, and TNF-α are closely related to impaired hemodynamics and may contribute to postoperative myocardial ischemia and deteriorated clinical outcomes after cardiac surgery (Deng et al. 1996; Hennein et al. 1994). This evidence concerns the gene CXCL8 and myocardial ischemia.
