Clinical TrialAtrial fibrillation in elderly patients after cardiac surgery: postoperative hemodynamics and low postoperative serum triiodothyronine.
The purpose of this study was to evaluate serum triiodothyronine levels as a trigger of postoperative atrial fibrillation (AF) in elderly patients undergoing cardiac surgery and to study the possible association of serum triiodothyronine levels with preoperative and postoperative hemodynamics. ⋯ In a group of elderly patients undergoing cardiac surgery, there was a strong association between a postoperative decrease of serum triiodothyronine levels and atrial fibrillation. The decrease of serum triiodothyronine levels was related to the changes of hemodynamic parameters only in the immediate postoperative period.
