I always invoke via a script (named "+") which has assorted 
figure-it-out logic before invoking mutt. You could sniff the terminal 
size and choose a narrower index_format for narrow terminals. (_And_ 
bind that to a keyboard toggle macro as well if you wanted.)

I've got a ttysize script which does this:

    stty -a </dev/tty \
    | sed -n '
          s/.* rows \([0-9][0-9]*\); columns \([0-9][0-9]*\).*/\2 \1/p
          t
          s/.*; *\([0-9][0-9]*\) rows; *\([0-9][0-9]*\) columns.*/\2 \1/p
          t'

but I'm sure there must be a more direct way.

Anyway, given the tty width you could make a choice about index_format.
