Effects of Triiodothyronine (T3) in Ischemic Heart Failure

Summary

This study aims to determine whether giving triiodothyronine (T3), a thyroid hormone, is safe and helps improve symptoms and signs of heart failure. The study is divided into 2 phases. In the first phase, participants have a 50-50 chance of receiving the study drug. Participants who are enrolled to receive the study drug will be admitted to the General Clinical Research Center (GCRC) for 5 days for oral thyroid hormone treatment and monitoring. They will have 4 additional follow-up visits over the next year. Participants who are not enrolled to receive the study drug will not be admitted but will have similar follow-up visits in the outpatient setting. Participants who do not receive the drug in Phase I will have the opportunity to enroll in Phase II of the study where everyone will receive the thyroid hormone treatment. If this study finds that patients have improved heart function after treatment with thyroid hormone without unacceptable side effects, this could result in a new treatment for patients with heart failure.
