Regardless of the mechanism, the therapy can really help people avoid bypass surgery.
It helped my father for 20 years.
Here is my anecdotal evidence. 1n 1995, my neighbor was being tested for a blockage. During the test, the wire hit the blockage, bent, and pierced the vein. So, it was very painful and he said, “Get me the H out of here.” He came home, and began chelation because of a friend doing it. He never had surgery, is now 77 years old, and works as hard as he ever did. Once a month he travels about 100 miles away for his treatment. Takes an hour or 2 and he is done.
