Worried about heart / pulse pressure

I'm a bit worried about my blood pressure but in particular my pulse pressure.  Blood pressure ranges from 119/40 to 139/65.  My average pulse pressure seems to be around 70-80. Below are a few readings I took over a couple of days (blood pressure and pulse pressure)-

119/40   79
121/43   78
116/43   73
117/40   77
118/41   77
116/41   75
111/41   70
129/50   79
115/60   55

Are these lower values something to be concerned with?  I went to the doctor with chest pains around a year or so back and he said I had a slight heart murmour.  I underwent tests at the hospital, ecg, excersise test, ultrasound etc and everything looked ok although something quite wasn't right but the examiner couldn't tell me exactly what as he wasn't qualified so it was passed over to the specialist.  Over a year has passed and I heard nothing back so thought no more of it untill recently when I took these readings!  I know the readings are correct as the rest of my family has tried using it and get average readings of 120/80.

I've used steroids in the past and this was when the chest pains seemed to start but I have stopped that all around 18months back.

As I remember a value above 60 is of some concern.  It doesn't bode well for a prediction of a future heart event...higher risk.  Your systole is very good, but the diastole is very low.  Are you on medication?  An individual that is in very good cardio condition can have a low diastole measurement, but around 40 would cause some people to pass out.

Since it has been a year since the examiner told you that "something wasn't quite right" I'd make an appointment with a Cardiologist especially since you were told that you had a slight heart murmur, and tell him/her about your concern for your low diastolic pressure.  I think the diastolic pressure is to low, but I'm not a doctor that is why I would see a Cardiologist if I were you.
