All values are means ± SD. *p < 0.05 vs 32 °C, †p < 0.05 vs 37 °C. A and B, parameters of best-fit end systolic pressure (ESP)-volume relation (ESPVR) obtained by the equation: A{1 − exp[−B(V − V0)]}. V0, volume intercept of ESPVR. mLVV, left ventricular volume at midrange. ESPmLVV, ESP at mLVV. PVAmLVV, pressure-volume area at mLVV.
