For table triggers adding an index to a table referenced by the trigger has no effect on the trigger state. Alteringa table referenced by the trigger on the other hand is likely to require Oracle to re-compile the trigger to ensure the code is valid prior to 11g and Oracle's more advanced dependency tracking.
Check DBA_DEPENDENCIES before altering any table to see what dependent objects are going to be affected.
Loss of object privileges can cause a trigger to become INVALID when the trigger code references tables owned by a different user than the trigger owner.
