Kaplan-Meier survival plots for all-cause mortality for 642 CAD patients stratified into 4 groups based on cut-off values for NT-proBNP (290.4 ng/L) and ratio fT3/fT4 (0.206) levels. fT3/fT4 – Free Triiodothyronine/Free Thyroxine ratio; NT-pro-BNP – N-terminal pro-B-Type natriuretic peptide. The group with low fT3/fT4 ratio (<0.206) and high NT-proBNP (>290.4 ng/L) (bottom line) had a worse prognosis than others groups (p < 0.001; by the log-rank test)
