What are the effects of hyperglycemia on mortality in patients undergoing cardiac surgery?
Multiple studies have shown that hyperglycemia during cardiopulmonary bypass is an independent risk factor for mortality in patients undergoing cardiac surgery. Studies such as the one conducted by Doenst et al. (2005) found that hyperglycemia is associated with increased mortality in this population. Gandhi et al. (2005) reported similar findings, with intraoperative hyperglycemia being associated with worsened hospital outcomes. Thus, it is evident that hyperglycemia increases the risk of mortality in patients undergoing cardiac surgery.
