Once I have opened the Recent Expensive Queries pane, I watch the queries being run on the SQL Server instance using the default sort settings: which orders queries by CPU usage against all databases. You can't capture an execution plan for encrypted stored procedures. While it is rare for a single new index to cause problems, maybe there are already a large number of indexes on this table and adding another will cause undue stress during data modification when all the indexes have to be maintained.
