Abstract
ObjectiveLow serum free triiodothyronine (FT3) levels are associated with the occurrence of coronary heart disease and with the prognosis of cardiovascular diseases. This study aimed to investigate the relationship between FT3 levels and risk stratification in Chinese Han patients with acute coronary syndrome (ACS) receiving percutaneous coronary intervention (PCI) treatment.MethodsPlasma FT3 levels and other parameters were measured in 191 patients with ACS who received PCI. The risk of adverse cardiovascular events was assessed using the Age, Creatinine, and Ejection Fraction (ACEF) score.ResultsFT3 levels were significantly lower in the high-risk group than in the medium- and low-risk groups. Serum FT3 levels were negatively linearly correlated with the ACEF score (r = −0.590). Stepwise regression analysis showed a negative correlation between FT3 levels and the risk of adverse cardiovascular events as measured by the ACEF score (standardized β = −0.261).ConclusionSerum FT3 levels are negatively related to risk stratification in patients with ACS. Serum FT3 levels may be used as a potential predictor for adverse outcomes of patients with ACS undergoing PCI.
