There are several things you can do to achieve that:
Best (thanks to Remy in the comments): "Another option is to use SetWinEventHook() to listen for EVENT_OBJECT_NAMECHANGE events. That is "more promising" than intercepting WM_SETTEXT messages, and less intrusive than "infiltrating"."
simple and boring (and it seems not really what you wanted): set a timer for the request so it is called in longer periods
propably the most promising one: Set up a Window hook with WH_GETMESSAGE to listen for the WM_SETTEXT which is messaged from the SetWindowTextA function
or go full crazy and CreateRemoteThread and infiltrate your enemy with a trusty spy.
