This treatment is claimed to be beneficial for atherosclerosis.

A study, funded by the Heart Foundation and conducted at the University of Otago, tested chelation treatment for people with atherosclerosis.

The study showed that the number of people showing an improvement in walking distance was not significantly different in the chelation group (60 per cent) compared with the other group (59 per cent).

Many people improve, irrespective of chelation therapy, because of the natural history of the disease and other measures taken to improve the disease such as medication, stopping smoking and changing eating habits.

The Centre for Advanced Medicine in Auckland has a client base in excess of 15,000 people. This facility specializes in chelation therapy which, in New Zealand, is considered a very effective treatment for atherosclerosis. The progress of the treatment is monitored through the use of sophisticated infrared imaging equipment. The Centre for Advanced Medicine also provides non-conventional cancer treatment, enzyme assays and chiropracty, and is involved in some very interesting research into the diagnosis, prevention and treatment of osteoporosis.
