Trigger 3: Hypertension Flashcards
1
Q
high BP affects
A
1.13 billion people
2
Q
how many death caused by high BP (e.g. stroke)
A
one in eight
3
Q
hypertensio def
A
sustained elevation of BP
4
Q
clinical def
A
systolic BP >140mmHg
diastolic BP> 90
5
Q
BP measurement
A
- doctor wraps cuff around your arm
- the cuff has a gauge which reads blood pressure
- doctor then inflates the cuff to squeeze your arm
- after the cuff is inflated, the doctor slowly lets air out
- ## whilst doing this they will listen to your pulse with a stethoscope and watch the gauge
6
Q
what scale does the gauge use
A
mmHg- to measure BP in your blood vessels
7
Q
systolic
A
measures the pressure in your blood vessel when your hear beats
8
Q
diastolic
A
measures the pressure in your blood vessels when your hear rests between beats
9
Q
normal bp
A
<120/ <80
10
Q
pre hypertension
A
<120-139/,80-89
11
Q
stage 2 hypertension
A
> 160 />100
12
Q
SBP is a
A
more important risk factor than DBP
13
Q
environmental risk factors for hypertension
A
smoking, diet and stress
14
Q
genetic factors environmental risk factors for hypertension
A
mitochondrial genome and nucelar genome (e.g. kidney and RAAS gene variants)
