TACT3a is a double blind, placebo-controlled, randomized trial to test a novel therapy, edetate disodium-based chelation of environmentally acquired toxic metals, to reduce cardiovascular events including amputation in high-risk diabetic patients.

The researchers propose to investigate the prevalence of gadolinium in the urine of patients with a prior gadolinium-enhanced MRI before and after a edetate calcium disodium challenge. Moreover, will investigate if there is any correlation of gadolinium urine levels with levels of endogenous (e.g zinc) and xenobiotic metals.

Trial to Assess Chelation Therapy 2 (TACT2) is a randomized, double blind controlled factorial clinical trial of edetate disodium-based chelation and high-dose oral vitamins and minerals to prevent recurrent cardiac events in diabetic patients with a prior myocardial infarction (MI).
