Effects of surgery on myocardial inotropic (left) and lusitropic (right) reserves. All measurements were performed at ZT8; values are mean ± SD (n = 6–8). Left: only strain had a significant effect; the asterisks correspond to the significance of differences as detected by post-hoc Tukey multiple comparison tests (***P < 0.001; **P < 0.01). Right: there was a significant interaction of strain with the effect of surgery on lusitropic reserve. The asterisks correspond to the significance of the differences detected by post-hoc Tukey multiple comparison tests (**P < 0.01)
