I've not personally done chelation therapy, but have read and researched many good things about it. Are you looking to use it to remove heavy metals or remove the calcification of the arteries? The EDTA chelation therapy does both. The therapy has been done as an outpatient treatment that is injected intravenously, but it can now be done using oral supplements at home as well. Anyway, I've heard several accounts of people using it to remove the calcification in their arteries, and it has worked well for them. It has also been used effectively for quite some time to remove heavy metals for the body that can be toxic. Good luck!
