[Prevalence and prognosis significance of euthyroid sick syndrome in critical illness]. / Prevalencia y significación pronóstica del síndrome del enfermo eutiroideo en patología crítica.

ABSTRACT

The prevalence and prognosis of the sick euthyroid syndrome (SES) was studied in 91 patients admitted to the ICU by determining free thyroid hormones (FT3 and FT4), T3 reverse (rT3) and thyrotropin (TSH). The prevalence of SES was lower than expected, type I being higher that type II. The acute coronary syndrome had a lower prevalence of SES than other clinical conditions. Patients who developed type II SES had a higher mortality rate.
