  Purpose
This study is planned to medicate oral T3(Liothyronine)to the patients who are planned to have OPCAB(off- pump coronary bypass graft surgery. The aim of this study was to assess the effects of oral triiodothyronine (T3) therapy on postoperative thyroid hormone concentrations, hemodynamic variables and outcomes in patients undergoing OPCAB in a randomized, controlled trial.

Condition Intervention
Non-thyroidal Illness Syndrome Drug: liothyronine sodium Drug: placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Supportive Care

Further study details as provided by Yong-Sun Choi, Yonsei University:

Primary Outcome Measures:
  • compare the serum T3 concentrations and the number of patients with serum T3 concentrations below the normal range between the groups [ Time Frame: until 36 hours after surgery ]

Secondary Outcome Measures:
  • difference of hemodynamic performance and myocardial injury [ Time Frame: during surgery and 36 hr after surgery ]
    difference of hemodynamic performance and myocardial injury between the groups


Other Outcome Measures:
  • major morbidity endpoints including acute renal failure, cardiovascular failure, stroke, mediastinitis, need for ventilator support for >48 h, and new onset atrial fibrillation [ Time Frame: until discharge of hospital ]
