a A representative example of the left ventricular pressure (LVP) waveform and its derivative in a nontreated rat. b Maximal first derivative of left ventricular pressure (dP/dtmax) at week 6 of treatment. The dP/dtmax was significantly (*P < 0.05) higher in the donepezil group (shaded bar, D) than in the nontreated group (open bar, N). c Left ventricular end-diastolic pressure (LVEDP) at week 6 of treatment. The LVEDP was significantly lower in the donepezil group (shaded bar, D) than in the nontreated control group (open bar, N). d Right atrial pressure (RAP) at week 6 of treatment. The RAP was significantly (*P < 0.05) lower in the donepezil group (shaded bar, D) than in the nontreated control group (open bar, N)
