- Abstract
Background: Subclinical hypothyroidism (SCH) is characterized by an elevated thyroid-stimulating hormone and normal free thyroxine. This study aimed to evaluate the influence of SCH on the recovery of patients after coronary artery bypass grafting (CABG). Methods: In this study, we selected patients who underwent CABG were identified. The postoperative outcomes were compared. We retrospectively reviewed and compared all-cause mortality, cardiovascular mortality, and cardiovascular events in 100 patients who underwent CABG. Results: The incidence of all-cause mortality after CABG was significantly higher in patients with SCH (55%) than in euthyroid patients (32%), with a hazard ratio of 1.70 (95% confidence interval, 1.10 to 2.63; P=0.018) after adjustment for age, sex, current smoking status, body mass index, underlying diseases, left ventricular dysfunction, and emergency operation. Conclusions: SCH or low total T3 might be associated with a poor prognosis after CABG, implying that preoperative thyroid hormonal status may be important in ischemic heart disease patients.
