Figure 1:

Baseline left ventricular haemodynamic variables mean (SE) or median (25%; 75%), and values obtained after CPB and 60 min of cardiac arrest with polarizing (STH-POL) and depolarizing (STH-2) cardioplegia. Bars represent SE. P_w, P_g and P_i: P-values for within subjects, between groups and interaction from two-way RM-ANOVA, respectively; ^#Significantly different from STH-POL at 180 min of reperfusion with Bonferroni post hoc test. SE: standard error of the mean; CPB: cardiopulmonary bypass; RM-ANOVA: analysis of variance for repeated measurement; CI: Cardiac Index; LVSP: left ventricular peak systolic pressure; LVEDP: left ventricular peak end-diastolic pressures; dP/dt_max and dP/dt_min: peak positive and peak negative of the first derivative of left ventricular pressure.
