Insights
EDTA chelation therapy shows promise for post-myocardial infarction (MI) patients, significantly reducing adverse cardiovascular events. Diabetic patients experienced even greater benefits, including reduced mortality, suggesting a potential new treatment avenue.
Area of Science:
- Cardiovascular Medicine
- Chelation Therapy
- Clinical Trials
Background:
- EDTA chelation therapy is used off-label for atherosclerosis.
- Large-scale randomized trials are needed to evaluate its efficacy.
Purpose of the Study:
- To review the results of the first large-scale randomized trial of EDTA chelation therapy.
- To assess the safety and efficacy of EDTA-based chelation infusions in post-myocardial infarction (MI) patients.
Main Methods:
- A $30 million National Institutes of Health-funded randomized trial.
- Involved 1708 post-myocardial infarction (MI) patients.
Main Results:
- An 18% reduction in a combined endpoint of death, MI, stroke, revascularization, or angina hospitalization (P=0.035).
- Diabetic patients showed a 41% relative risk reduction (P=0.0002) and a 43% reduction in total mortality (P=0.011).
- Favorable safety data were observed; reduced oxidative stress is a proposed mechanism.
Conclusions:
- EDTA chelation may be a well-tolerated and effective treatment for post-MI patients.
- Further replication and mechanistic studies are warranted before widespread implementation.
Purpose Of Review:
EDTA chelation therapy has been in off-label use for the treatment of atherosclerosis. We review the results of the first large-scale randomized trial of this treatment.
Recent Findings:
The trial to assess chelation therapy was a $30 million National Institutes of Health-funded study of the safety and efficacy of EDTA-based chelation infusions in 1708 post-myocardial infarction (MI) patients. The trial to assess chelation therapy demonstrated a significant (P=0.035) 18% reduction in a combined primary endpoint of death, MI, stroke, coronary revascularization, or hospitalization for angina. In diabetic patients the benefit was more extreme, with a 41% relative reduction in risk (P=0.0002) and a 43% reduction in total mortality (P=0.011). Safety data were favorable. A reduction of oxidative stress by chelation of toxic metals has been proposed as a possible mechanism of action.
Summary:
Recent research suggests that EDTA chelation may be a well-tolerated and effective treatment for post-MI patients. Future replication and mechanistic studies are important prior to implementation in all post-MI patients.
