Chelation therapy has been in use for over fifty years to help people with heart disease, diabetes and many chronic conditions. The treatment is covered in the medical textbook by Saunders, one of the big publishing companies serving the medical community, called "Cardiovascular Drug Therapy". The effectiveness and safety has long since been established if you look. Chelation therapy (EDTA) is the therapy of choice when children have toxic overloads of lead. If you study you will find that heavy metals, molecules with an electrical charge, are present in the muscle fiber of people with heart disease, the muscle wall of the artery and the heart itself. Ionic calcium is a problem and is the reason and artery becomes hard in the first place. If you remove the ionic calcium you restore the flexibility of the artery and it can streach again with each heart beat delivering more blood to the area it serves. Arteries in your heart also have arteries serving them, chelation affects the circulatory system throughout the body.
