‘Low — T3 syndrome’ among patients with acute myocardial infarction

Background Recent clinical studies have found that cardiovascular incidents are sufficient triggers to affect HPA hypothalamic-pituitarythyroid axis and cause a decrease in the serum levels of triiodothyronine (T3). This phenomenon is so called ‘Low — triiodothyronine (T3) syndrome’ and is related to changes in heart remodeling. However, the pathophysiology of Low—T3 syndrome remains unclear. The present systemic literature review was designed to organize the latest scientific papers and is seeking to draw evidence-based conclusions regarding clinical aspects of the topic.
