Is chelation therapy truly effective in removing heart-arterial blocks?

No: Chelation therapy has never been shown in any reputable clinical trial to be of benefit for vascular disease. It is frowned upon by the credible authorities. The argument is, if a provider thinks this works, why are they unwilling to do the study to prove it? An expensive waste of money.

Not for 100% blocks: Although chelation therapy is very effective for improving blood flow, it will not "unclog" a completely blocked artery. However, atherosclerosis does not effect single arteries. It is a systemic problem. Therefore, for those with complete or near-complete blockages, i recommend stents or bypass, followed by chelation to improve blood-flow throughout the body and prevent progression.

Chelation Study Here: The tact nih study on IV chelation is one of the few large clinical trials that showed some benefit.
