Brief Summary: The purpose of this study is to determine the safety and effectiveness of EDTA chelation therapy in individuals with coronary artery disease.
Detailed Description:

This study is a comparing 40 infusions of the standard chelation solution versus 40 infusions of placebo. Chelation therapy, as practiced in the community, also includes the use of high dose antioxidant vitamin and mineral supplements. Thus, any clinical benefit of chelation therapy may be due either to the effect of EDTA chelation, or high dose supplements, or both. Therefore, we are conducting a 2X2 factorial design to independently test the effects of a high-dose supplementation, versus a low dose regimen to simply replace chelation-related losses. The primary endpoint of this trial will be a composite of all cause mortality, myocardial infarction, stroke, hospitalization for angina and hospitalization for congestive heart failure.

The results of TACT will provide either a significant positive result or an informative null result upon which rational clinical decision-making and health policy can be based.
