80mg, really?
i always thought it was in the range between 20-40mg
as already mentioned - it reduces the risk of thromboembolism
which means, generally speaking, that it inhibits the clotting-ability of the thrombocytes, therefore the possibility that a bloodclot in some of your bloodvessels will build up and then be washed through your body until it blocks some vessel somewhere is reduced
promote a healthy heart? from the top of my head i could imagine that it reduces the risk of a bloodclot forming on the ground of an atherosclerotic lesion, other than that,...
i'm no big fan of ASA and i wouldn't take it daily if it hasn't been prescribed to me because of a reason
interesting fact: everytime you take ASA you'll have a mico-bleeding in your stomach (because of the chemical principle called 'ion trapping') (as far as i know ASA is one of the main reasons for gastro-intestinal bleedings _and_ ulcera)
i'm sorry for my inability to express myself correctly on medical terms - it's hard to transfer it from german to english
