In "City on the Edge of Forever" McCoy's actions prevent the Federation from ever forming in the "prime" universe, they aren't confined to an alternate timeline.
Same with "First Cointact" - the Borg's trip to the past results in Earth being assimilated, and the Enterprise is only protected by being caught in the sphere's wake. The suggestion is that the rest of the fleet from the battle no longer exist.
In the TNG episode "Time's Arrow" (the episode with Mark Twain) they find Data's head in the prime universe, having been left back in the 1800's.
Time travel in "Yesterday's Enterprise" changes the prime universe to prevent war with the Klingons.
Oh, but in this case, the prime universe is untouched... :unsure
