Histogram depicting myocardial infarct size as a percentage of area at risk in the control, desflurane, calphostin C + desflurane (Calph + Des), PD98059 + desflurane (PD + Des), calphostin C (Calph C), and the PD98059 groups. Data are presented as mean ± SD. * P < 0.05 versus control; § P < 0.05 versus desflurane-induced preconditioning.
