heart attack and aspirin

I heard that it si good practice to keep two aspirins by one's bedside. Should it happen that one should wake up with chest pains and suspect that a heart attack is imminent, then swallow these two aspirins, call the neighbour, say heart attack and request for emergency help. Say you have taken two aspirins. And not to lie down.

This is important information but is there anyone out there who can verify this as the right thing to do in a suspected heart attack situation...taking aspirins i mean.
