Valor pronóstico postoperatorio del extremo aminoterminal del propéptido natriurético tipo B en el trasplante cardíaco

The non-survivor patients showed higher NT-proBNP concentrations than survivors, with a median of NT-proBNP concentration on the 15th day post-transplantation of 20632 ng/L (IIC: 6183 to 37925 ng/L) and 3923 ng/L (IIC: 1752 to 6890 ng/L) in the non-survivors and the survivors groups, respectively. The hazard ratio of mortality was 8.5 times higher (95% CI: 1.7 to 44.2) in those patients with NT-proBNP concentrations over 7500 ng/L on the 15th day post-transplantation.
