Therapists point out that about 500,000 chelation therapies are being done in the USA alone every year and the patients are very happy, placebo effect or not.

There is not much risk in chelation therapy as compared to the surgery. The results were even better for the patients who were treated for peripheral vascular disease. So, 96-98 percent of the patients treated reported improvement after chelation therapy.
