The therapeutic benefits of low-dose ("baby") aspirin in terms of
prevention of cardiovascular disease is not related to the coating.  The
effect of the coating is only to modify the release of the contents from
the tablet in the digestive tract.  What Bayer calls "safety coated" is
enteric coating: a way to delay release of the medicine until it has
moved past the stomach in an attempt to reduce stomach upset (or worse,
for people with existing stomach problems).

As long as your physician has determined that low-dose aspirin is safe
and suitable for you to take, the only important thing is to take it.
Coated, or uncoated doesn't make any difference.  Why, Bayer even makes
a low-dose chewable aspirin; it'll work just as well, too.

The coated tablet is only advantageous if your stomach is sensitive to
aspirin.  I take coated.  Discussed this with my cardio and we both agreed
that one should have some uncoated aspirin (adult) on hand in case of cardio
emergency (chew, hold under tongue).
Frankly, I would take uncoated aspirin but I can't stand the taste of it.
