The values are the mean ± SE. n, number of hearts; HR, heart rate (beats per min, bpm); FR, flow rate (ml/min); LVDP, left ventricular developed pressure (cmH2O); ±dp/dt, rates of pressure rise and fall (cmH2O/ms), respectively. The groups are: WT: I/R, Wild type subjected to ischemia-reperfusion without preconditioning; qKO: I/R, Quadruple knockout type subjected to ischemia-reperfusion without preconditioning; WT: PC & I/R, Wild type subjected to preconditioning and then ischemia-reperfusion; qKO: PC & I/R, Quadruple knockout type subjected to preconditioning and then ischemia-reperfusion.
