Hi, I've got a few questions concerning CVD, and I'd be grateful if some people can help

So how/why does alcohol increase blood pressure?

The textbook mentions the use of aspirin, and how it reduces the stickiness of the platelets. It says that some are allergic to aspirin, so use clopidogrel, so I assume they do the same thing? And is it for both, that they can cause stomach bleeding?

And it is said to be good to eat more oily fish, but how does it help?

Also, it doesn't specify on the syllabus, but are we expected to know about non-starch polysaccharides, acting as a gel which traps cholesterol and prevents its absorption?

Thanks for your help

alcohol is absorbed as sugar in the body,
so in order to metabolize the sugar, insulin is needed.

Rise of insulin will cause the blood pressure to increase.

yup, if I am not mistaken (I am doing Unit 5 biology edexcel) . clopidogrel and aspirin do the same thing but clopidogrel will have greater effect (as in the bleeding of the stomach will be more severe).

Oily fishes are rich in the good fats. Good fats will transport the bad fats aka cholesterol to the liver to be metabolized.

Hope this helps

Erm are you sure about the insulin bit? We were taught about the production of ethanal..

Umm, care to clarify a bit on that? my memory is bad nowadays :/ sorry, not really sure.

Are you trying to say that the production of ethanal is the result of oxidising the alcohol?

Quote me please so that that I know that you replied. Thanks

Erm well I've heard a few different reasons, I'll just list them.

• The liver cannot metabolise (process chemically) angiotensin, and so blood pressure cannot be controlled.
• Excess alcohol consumption means that glucose and lipids cannot be removed from the blood.
• Also, more ethanol would be produced, and though most is used in respiration, some may end up as VLDL’s which increase the likelihood of a plaque deposition.

But I'm not sure if they are all true. :/ Did you do the Edexcel course too?

Alcohol is metabolized to form LDL's, and this increases the risk of plaque formation in artery walls, which in turn increases blood pressure....Also it damages liver cells which makes the liver unable to carry out detoxification as well as process carbohydrates, fats and proteins.

yes....about aspirin and clopidogrel

Oily fish helps remove LDL from blood.

Well, i guess it isn't essential to know about the non starch polysaccharides, but then again i found it in 2 sets of notes given by 2 teachers as well as in some textbooks so i guess it is needed but idk.....

  • Oily fish contains unsaturated fats which contribute to the production of HDL which help with the removal of excess cholesterol by transporting cholesterol from the blood to the liver to be broken down.


  • Excess Alcohol consumption can damage the liver which breaks down lipids and glucose, excess lipids in the blood can build up in the inner lining of the arteries, narrowing them and therefore increasing/raising blood pressure.


In terms of glucose, I myself need to recap the reason behind that.

Hope this has helped
