The admission NT-proBNP levels in group B was lower than that in group A, and the difference was statistically significant (P < 0.05), but the differences in bleeding, heart failure, cardiogenic shock, highest hs-cTnI (ng/ml) levels, adverse events and length of stay were not statistically significant compared with group A (P > 0.05, Table 4). Here, NPPB is linked to heart failure.
