Medical Forum / General / Cardiology / January 2005observation concerning diastolic BP readings
in passing, Hello Dr. Chung, Zee, and Bill.. may 2005 be good to you ! I had a flash this morning while taking my BP sitting in bed nearly every morning. In general, I'm always disappointed by the diastolic reading first thing in the morning : it's always high. This morning was no exception, except for a second measure taken just after I got up for a look around the house. Diastolic pressure dropped 10-15 points. I'd like your comments concerning the following thoughts. As I understand it, diastolic pressure readings indirectly measure the elasticity of the arteries. The arteries act like a spring release to assist the heart on the upflow of the blood. Without this, the heart has to pump harder. It seems to me that the vascular system upon waking up in the morning may still "stiff" in the same way legs and arms are stiff when we first get up and therefore measure a higher diastolic. Upon getting up, going to the bathroom, opening shutters, the vascular system gets warmed up and loosens up, thereby leading to lower diastolic readings. What do you think, where are the flaws or the merits of these suppositions !? liaM > in passing, Hello Dr. Chung, Zee, and Bill.. may 2005 be good to you ! > [quoted text clipped - 21 lines] > > liaM Woke up this morning Snow still about Beauty and Pain Walked down the hallway Breath OK Kitchen said clean me I said afterwards Children went about I stayed home Time to shop Time to work out Time to ready dinner It goes by fast Vascular system on auto. Hi Liam! Flaws are very hard to ascertain in a temporal world. Who knows?

"Who knows" indeed ! I have my doubts ! Grave doubts and thanks how the world wakes up in the morning even after nights spent under a nearly full moon.. One day we should scheme to surprise Zee and plan to show up together at her doorstep ! That'll be the day.. liaM Chocolate > Chocolate This is sweet http://www.answers.com/ ?

The arteries have a capacitance to keep the diastolic pressure from going to zero in between heart beats. > Without this, the heart > has to pump harder.

It would have to be the other way around to explain a higher diastolic. > Upon getting up, > going to the bathroom, opening shutters, the vascular system gets warmed > up and loosens up, thereby leading to lower diastolic readings. More likely is that there is some fluid shift away from the vasculature into the tissues upon arising and walking about. Also there will be increased renal output because of the increased cardiac output. This reduced vascular volume will lead to a decreased diastolic pressure. > What do you think, where are the flaws or the merits of these > suppositions !? See above.
