Postoperative troponin T levels. The course of postoperative troponin T release; all groups compared to controls (represented in black in all panels). Helium preconditioning (He-pre) does not affect postoperative troponin T levels compared to controls (a), nor does helium postconditioning (He-post, b) or the combination of helium pre- and postconditioning (He-PP, c). Anesthetic preconditioning (APC) with sevoflurane did also not affect postoperative troponin T levels compared to controls in the present study (d). X axis represents troponin T level in μg/L, values in median ± interquartile range. Y axis represents time (hours)
