The study aimed to examine how mild thyroid dysfunction impacts the outcomes of patients with acute ST segment elevation myocardial infarction (STEMI) in a Chinese population.
Out of 1,176 STEMI patients analyzed, those with mild thyroid dysfunction (particularly low triiodothyronine syndrome) showed significantly higher risks of in-hospital and long-term mortality compared to patients with normal thyroid function.
The findings suggest that patients with subclinical hyperthyroidism and low triiodothyronine syndrome have a notably worse prognosis, highlighting the importance of monitoring thyroid function in STEMI patients.
