Figure 4. Effects of sufentanil (SUFN) or HOE 642 alone or in combination on left ventricular developed pressure and left ventricular end-diastolic pressure during reperfusion after 60 min of ischemia in hearts. Values are mean +/- SEM and depict the percentage of preischemic values. *P < 0.05 for either the HOE-alone or HOE + SUFN groups compared with the two other treatments. #P < 0.05 from control. n = 6 for all groups except control (n = 7).
