The Effects of Hypertension on the Body

The Effects of Hypertension on the Body


>Now let’s go to hypertension, or you know
obviously high blood pressure, I know we have a 3d image, and I’d like you to
explain to us exactly, what’s happening in the body when we have hypertension?.>
Well here you see an artery cut in cross-section, so this would be the
outside of the artery here, and we see the artery moving in and out, so as it moves
in that’s what we call systolic blood pressure which is the top number
offering a 120 or below is considered ideal, and then when the artery is
stretching here that’s what we call diastole which is the blood vessel in
its relaxed state, so systole is the heart contracting, diastole is the heart
in relaxation, top numbers the systolic blood pressure, bottom number is the
diastolic blood pressure, and those numbers we want at all times as much as
possible below 120 over 80.>And so when one is doing like exercise, or running, or
pilates, and obviously are getting that heart rate going, which is the number
that goes up?.>The normal response blood pressure response to
exercise, is that the systolic blood pressure which is commensurate with the
heart contracting, which during exercise the heart has to contract it contracts
more frequently, that is the higher the heart rate, and it pumps out more blood
with each beat of the heart, so the systolic blood pressure will often go up
significantly depending upon the level of our severity of activity, the
diastolic blood pressure should actually stay the same or go down, so one of the
things when we’re doing an exercise stress test they may be looking for
blockage by looking at EKG abnormalities we also pay very close attention to the
blood pressure response to the exercise, because one of the early changes in
people with high blood pressure, is that their top number goes up, but their
diastolic blood pressure goes up, and that’s a sign already that the blood
vessels are involved with the effects of high blood pressure.
