Doppler Map of 100

What's the significance of a map of 100? Doctor wants to double my Coreg now.

My understanding is that the MAP, Mean Arterial Pressure, should be between 65 and 90. It appears as if they are trying to lower the MAP so that the pressure created by the pump doesn't collapse the left ventricle by drawing too much blood out for circulation. Might be incorrect, but that was the explanation I got when the slowed the pump and increase blood pressure medicine.
