Gualandro DM, et al. - Researchers conducted a direct comparison between preoperative high-sensitivity cardiac troponin (hs-cTn) I and T concentration to find out which of these would serve as a better predictor of major cardiac complications following non-cardiac surgery. This study included 1,022 patients undergoing non-cardiac surgery, in whom hs-cTnI and hs-cTnT were measured preoperatively in a blinded fashion. The hypothesis that the type of surgery may impact on the predictive accuracy of hs-cTnI/T was tested. They found that prediction of major cardiac complications after non-vascular surgery was enabled by preoperative hs-cTnI and hs-cTnT concentrations, while, only preoperative hs-cTnI was an independent predictor of major cardiac complications in patients undergoing vascular surgery.
