Association between Low Free Triiodothyronine Levels and Poor Prognosis in Patients with Acute ST-Elevation Myocardial Infarction

Figure 1

Kaplan-Meier survival curves for (a) 30-day mortality, (b) 1-year mortality, (c) 30-day major adverse cardiac events (MACE), and (d) 1-year MACE in patients in the low and normal fT3 groups. The log-rank tests showed that all four parameters (mortality and MACE occurrence) were higher in the low fT3 group than in the normal fT3 group (all ). After adjustment for age and sex, all associations remained significant, except for 30-day and 1-year mortality and 30-day MACE in female >75 years of age (all ); only the difference in 1-year MACE remained significant ().
