Experiments are conducted at the O.L.V. Hospital, Aalst, Belgium, in a fully equipped operating room and intensive care facility and in the presence of board-certified anesthesiologists for safety reasons. After approval by the institutional ethics committee and written informed consent, all adult patients scheduled for different types of cardiac surgery between June 2013 and June 2014 will be enrolled. Collected data include demographic information, presence of co-morbid conditions and basic preoperative laboratory testing (including Hs-cTn and CK-MB) (Table 1) as well as per- and postoperative factors (Table 2).
