Hello. I guess my lack of quoting does kind of mess things up. The original poster also talked about five or six hours in emergency rooms before they admitted he had had a heart attack. I understand there is a new test available to determine if you are having a heart attack so anti-coagulant type {*filter*} can be given when they can do some good. This test is much quicker - like a half hour instead of five hours. As I am sure you know much bypass surgery was found in about 1980's to have little efficacy. There are many "standard" practices which, of course, have doubtful efficacy. I'm a chemical engineer and am hardly anti-technology. In fact I'm amazed, often, at all the "art" in conventional medecine. Lately my newest laugh is so called controlled studies in ADD comparing psychotropic medications to placebo. Like any idiot,bystander, acquaintence, much less doctor or parent can't immediately know an individual has taken a psychotropic drug and of course the patient knows. Geez. If all chelation does is have someone sit there for five hours, talk to other heart patients, remind not to eat cholesteral it may beat out a lot of "conventional" stuff. And with low danger, it may even somewhat work for someone. Cathy.
