The IL-6 promoter polymorphism (-174 G/C) does not affect the incidence of sepsis. However, the GG homozygous genotype is significantly associated with an improved survival in sepsis. Because this association is independent from the systemic IL-6 response, we suggest that other genetically linked polymorphisms may be the primary cause.

A-type natriuretic peptide is primarily influenced by volume reloading of the heart after cross-clamp, whereas the secretion of B-type natriuretic peptide (BNP) is related to the duration of ischemia and long-term left ventricular pressure and/or volume overload. Preoperative BNP, but not postoperative BNP, concentrations predict long-term outcome after coronary artery bypass grafting.

The agreement between EV-CO and TOE-CO is clinically acceptable, and these two techniques can be used interchangeably.
