The results of a Duke University study recently published in the "New England Journal of Medicine" indicate that of the nearly 400,000 people in the U.S. each year who undergo a bypass operation using a heart-lung machine, an estimated forty percent risk a substantial decrease in mental ability within five years after the surgery. Dr. Elmer Cranton published "Bypassing Bypass" in 1984 as a comprehensive introduction to EDTA chelation therapy, which opens blocked arteries without invasive surgery. The book became increasingly popular among consumers and health care providers seeking a safer, noninvasive, and lower-cost alternative to the traditional bypass surgery. With the advancements in medical technology, scientific research, and an increase in the number of practitioners offering chelation therapy, Dr. Cranton knew that an updated, expanded edition was needed. "Bypassing Bypass Surgery" will bring readers up to date on the latest studies and findings regarding chelation therapy and its current status in the medical community.
