When the subgroup of in-hospital death was compared to that ofpatients discharged, we observed that the first showed higher baseline BNP [770pg/mL (320-1.260) vs 227 pg/mL (123-553); p = 0.017]; a higher incidence ofpulmonary arterial hypertension (54.6% vs 21.6%; p = 0.024); CRF (81.8% vs 51.2%;p=0.048); and ARF (45.5% vs. 11.2%; p = 0.008). Here, NPPB is linked to Hypertension.
