Cardiovascular disease, plz helppppp

Postby zabida » Sat Oct 11, 2008 8:42 pm

1: why can elevated blood pressure increase the risk of cardiovascular disease?
I have done some reasearch and i think it has something to do with atheroslerosis but i don't know how so please help.

2: what happens to the brachial artery when the pressure of the blood pressure monitor decreases to determine the diastolic blood pressure? I think that the brachial artery closess but why is this if it is right.

3: the chance of a 15 year old male dying of haemorrhagic stroke is 8, the ppopulation for males are 1778000. how do u work out the probabilty? Is it 1778000/100 then multiply by 8 , or 1778000/8*100

i really tried my best but i am just not sure so please help me, i have to understand before monday.
thank you for your help

1. http://www.americanheart.org/presenter. ... ifier=4440

2. You are right there is a good reason, for example if you need to get toothpaste from the tube you squeeze it, so if you want move the blood along once the pressure drops............................

3. I assume you want the probability as a percentage in which case this should help
