Beneficial effects of EDTA chelation for people with cardiovascular disease have been reported since the 1950s (Jick & Karsh, 1959).
This has been confirmed in the TACT trial which found chelation patients had a modest reduction in cardiovascular events (Lamas, et al., 2013). A TACT sub-study found significant benefits for people with diabetes (Escolar et al., 2014) – read more detail about that.
Lead and other metals have also been identified as risk factors for cardiovascular disease and reducing blood lead levels through chelation may reduce the risk (Schwartz, 1991; Alissa & Ferns, 2011).
EDTA is well known as an anticoagulant in laboratories. Some evidence suggests there is an increased risk of blood clots that lead to myocardial infarction after insertion of stents, and EDTA chelation may reduce the risk (Chappell, 2007).
Case reports indicate that EDTA chelation may help reduce blood pressure (Jackson, 1992), and improve circulation (Jackson, 1999).
Intravenous Chelation Therapy
EDTA binds with varying affinity to both harmful and essential extracellular metals and facilitates their excretion from the body. It is important to take a multivitamin supplement while having chelation to replace the essential minerals. The multivitamin may also help relieve metal-induced oxidative stress, but additional vitamin C is typically administered with the EDTA for greater benefit.
There are some risks associated with chelation: calcium disodium EDTA may cause renal damage (Flora & Pachauri, 2010) and too-rapid an infusion of disodium EDTA has been linked to fatalities caused by hypocalcemia (Brown, et al., 2006). These risks are managed by slow infusion of EDTA, monitoring renal function and providing extra calcium.
