The Institute of Endocrinology and Preventive Medicine, headed by Medical Director Marina Johnson, M.D., is seeking Dallas County participants for a major National Institute of Health (NIH) clinical study of diabetes.

Participants must be 50 or older, have diabetes and have had a previous heart attack. A 2013 NIH study showed that diabetics with heart disease that received IV chelation had a 50 percent reduction in repeat heart attacks, stints, bypass surgery and improved mortality. This clinical trial, called TACT2, seeks to confirm these positive benefits of IV chelation.
