Chelation therapy is a process of removing heavy metals such as lead and cadmium from blood as a means to prevent heart attacks. It is an old treatment that was felt to be quackery when I learned about it as a medical student at Johns Hopkins many years ago. But now there is convincing evidence that it can dramatically reduce the incidence of heart attacks without the use of toxic drugs. Cardiologist GA Lamas in Miami, originally a skeptic of the technique has performed studies showing marked reduction in heart attacks incidence with this technique – and new larger studies are underway. At a time when large percentages of patients refuse to take statin drugs for heart disease, and other pharmaceuticals, because of onerous side effects, alternative safe and effective treatments like this are becoming increasingly popular.
