This is one you can't decide for yourself, but I'm guessing that successful bypass surgery would have included cleaning out at least the blood vessels operated on. There is no good evidence on whether or for whom chelation works, as with most natural therapies nobody spends the money to do conclusive studies (not that allopathic studies are conclusive, either). You would have to consult with your heart specialist and a practitioner of chelation therapy, but at this point you must be on medication if you've just had bypass surgery. You have a lot of homework to do, and you need experts, not us.
