it is when artery walls become clogged with plaque and atheroma/ cholesterol
1 of 16
what parts of the body does atherosclerosis affect?/ diseases caused by atherosclerosis in different parts of the body
brain- cerebral infarction+ ischaemia which causes cerebral vascular disease and strokes
heart- IHD, MI
Aorta- can cause rupture and sudden death
kidneys- renal vascular disease
gut- gut ischaemia and mesenteric ischaemia
legs- PVD
what is ischaemia?/ what are some of the symptoms.
narrowing of artery which reduced flow of blood and delivery of oxygen to tissues. muscles have to work harder
4 of 16
where can ischaemia be seen?
cardiac angina, intermittent laudation in legs, mesenteric angina in guts etc
5 of 16
what happens if the plaque on the artery wall ruptures?
thrombus formation over the plaque and blocks the artery.
6 of 16
if plaque ruptures in atherosclerosis, what does that lead to?
infarction= tissue death
Example:
MI
stroke (blood supply to part of brain is cut off), cerebral infarction
7 of 16
what are
a. the modifiable risk factors
b.non-modifiable risk factors
for atherosclerosis ?
a. smoking, hypertension, high cholesterol, DM, obesity, harmful use of alcohol
b. genetic predisposition, increasing age, M>F
8 of 16
What measurement is considered as high blood pressure?
>140/90
>150/90 if over 80
9 of 16
what is normal blood pressure?
between 90/60 and 120/80
if below 90/60= low BP
10 of 16
What are the primary causes of hypertension? what what does primary cause mean
obesity, harmful use of alcohol, inactivity, smoking, high salt diet, genetic factors. it means that there is no single underlying cause but the hypertension is related to the factors listed above
if hypertension
is untreated, would you still carry out surgery requiring anaesthetic ?
no
