In our STEMI, the H-FABP cut-off point in mortality was 62.75 ng / ml from the ROC curve, an increase in H-FABP > 62.75 ng / ml had a risk of mortality is 18.2 times higher, 95% CI: 2.31 - 143.25, p < 0.01 is higher than the predictive ability of NT-proBNP and Hs-Troponin T Research by author Giao Thi Thoa (2018) in ACS subjects, the AUC of H-FABP with in-hospital mortality was 0.83 (95% CI: 0.75 - 0.89) higher than the value of NT-proBNP of 0.75, Killip is 0.79.
