Fernald has no entry of its own for attention; he lists it under care, industry.
Where he writes about it:
Care also signifies watchful attention, in view of possible harm; as, "This side up with care;" "Take care of yourself;" or, as a sharp warning, "Take care!" Caution has a sense of possible harm and risk only to be escaped, if at all, by careful deliberation and observation. — from care
Heed implies attention without disquiet; it is now largely displaced by attention and care. — from care
