Is There a Role for EDTA and Oral Vitamins in the Management of CAD?

A 67-year-old Caucasian male patient presents to establish cardiology care after recently moving into your area. He has a history that is significant for type 2 diabetes mellitus, systemic hypertension, ischemic cardiomyopathy, and benign prostatic hypertrophy. He was admitted for non-ST-segment elevation myocardial infarction 6 months ago for which he underwent percutaneous coronary intervention with drug-eluting stent placement in the proximal left anterior descending coronary artery. He has remained free of any further anginal symptoms.

Echocardiogram showed global left ventricular dysfunction with an ejection fraction of 35%. Medications include aspirin, clopidogrel, carvedilol, atorvastatin, lisinopril, and eplerenone. He tolerates his medications very well and reports no side effects. As part of his post-myocardial infarction (MI) cardiac rehabilitation, he joined the local YMCA where he met his gym buddie. His gym buddy is a big proponent of "alternative therapies and complementary medicine" and advised the patient to try a new regimen that the gym buddy had read about recently in a medical journal. The journal stated that ethylenediaminetetraacetic acid- (EDTA-) based chelation and high-dose oral vitamins can benefit patients like him greatly. The patient seeks your expert opinion on this issue.
