The National Institutes of Health (NIH) is conducting a nationwide study on the safety and effectiveness of chelation therapy, an investigational treatment for people with heart disease. Chelation therapy uses a man-made amino acid, called EDTA (ethylene diamine tetra-acetic acid), which is added to the blood through a vein. For many years, people with heart disease have considered chelation therapy, despite a lack of definitive evidence. The NIH study is the largest clinical study to be conducted on chelation therapy. It is 20 times larger than any previous study and is designed to provide the answer to this important question. Results are expected in about 5 years.

More than 100 medical institutions across the country have been selected to take part in the study. You are receiving this advisory because there is a participating local site near you. For an up-to-date list of participating sites, please visit
