How might EDTA chelation therapy work to clear blocked arteries?如何可能的EDTA螯合疗法的工作，以清除阻塞动脉？

Several theories have been suggested by those who recommend this form of treatment.几个理论已建议由那些谁推荐这种形式的治疗。 One theory suggests that EDTA chelation might work by directly removing calcium found in fatty plaques that block the arteries, causing the plaques to break up.其中一个理论认为的EDTA螯合会的工作由直接删除钙发现，在脂肪斑块阻塞动脉，导致斑块打破。 Another is that the process of chelation may stimulate the release of a hormone that in turn causes calcium to be removed from the plaques or causes a lowering of cholesterol levels.另一个原因是，这一进程的螯合，可刺激释放激素这反过来又导致钙被遣送离境，从斑块或导致降低胆固醇水平。 A third theory is that EDTA chelation therapy may work by reducing the damaging effects of oxygen ions (oxidative stress) on the walls of the blood vessels.第三个理论是，的EDTA螯合疗法可能会减少工作所造成的破坏性影响氧离子（氧化应激）对墙的血管。 Reducing oxidative stress could reduce inflammation in the arteries and improve blood vessel function.减少氧化应激可减少炎症的动脉和改善血管功能。 None of these theories has been well tested in scientific studies.没有这些理论一直行之有效的，科学的研究。
