The association of the serum free triiodothyronine to free thyroxine ratio with contrast-induced nephropathy and long-term outcomes in elective percutaneous coronary intervention: a retrospective study
Puntos clave
This research aims to explore the link between serum FT3/FT4 levels and the risk of contrast-induced nephropathy (CIN) and long-term mortality in patients undergoing elective percutaneous coronary intervention (PCI).
Retrospective analysis of elective PCI patients
Assessment of serum free triiodothyronine and free thyroxine levels
Evaluation of incidence of contrast-induced nephropathy and long-term mortality
Significant association found between FT3/FT4 levels and incidence of CIN
Higher FT3/FT4 ratios correlate with increased long-term all-cause mortality
Resumen
The FT3/FT4 level was significantly associated with both incidence of CIN and long-term all-cause mortality in patients undergoing elective PCI.
