OBJECTIVE: To describe thyroid hormone profile in patients with acute coronary syndromes (ACS), divided into two groups: 1) unstable angina and/or non-ST-segment elevation acute myocardial infarction (UA/NSTEMI); 2) ST-segment elevation acute myocardial infarction (STEMI), as well as in patients that progressed or not to death, according to the groups.
METHODS: Seventy ACS patients admitted to the coronary care unit of the Hospital dos Servidores do Estado, Rio de Janeiro, were prospectively studied. Blood samples were collected on day 1 and on days 4 and 7 following admission. Clinical evaluation and electrocardiograms were performed during hospitalization.
RESULTS: Of the 70 patients admitted, 13 (18.6%) had "euthyroid sick syndrome" (ESS), a condition characterized by decreased serum T3 and/or free T3, increased serum reverse T3 (rT3), plus normal serum TSH, T4, and free T4. Patients belonging to the STEMI group showed early elevations, in addition to higher mean reverse T3 (rT3) and lower mean T3 and free T3 levels. In coronary heart disease patients that progressed to death, hormonal findings were consistent with those found in the ESS, with more expressive rT3 and T3 mean values.
CONCLUSION: Our results show the importance of recognizing the "euthyroid sick syndrome" in coronary heart disease patients, suggesting an association with poorer prognosis in patients with acute coronary syndrome.
