Hemodynamic studies of left ventricles. (a) Left ventricular pressures of the sham and SAC groups at the 3rd week post surgery, and (b) left ventricular pressures of the three groups at the 20th week post surgery, (c) +dP/dt and –dP/dt of the sham and SAC groups at the 3rd week post surgery and (d) +dP/dt and –dP/dt of the three groups at the 20th week post surgery. n=4 in each group. LVEDP, left ventricular end-diastolic pressure; LVESP, left ventricular end-systolic pressure; SAC, suprarenal aortic constriction; Ud, udenafil.
