NPPB and pulmonary edema: Comparing with those with HFrEF, the population with HFpEF were older (76.7 ± 13.0 versus 72.5 ± 13.9 years, p = 0.01), consisted of more female patients (67.5% versus 42.5%, p < 0.001), presented higher serum NT-pro-BNP level at hospitalization (9072.3 ± 10113.8 versus 13602.3 ± 13168.1, p = 0.002), had longer length of hospital stay (13.9 ± 12.9 versus 10.7 ± 10.00, p = 0.026), showed lower proportions of presenting pulmonary edema (21.1% versus 37.0%, p = 0.005), and demonstrated lower proportions of taken oral diuretics (50.4% versus 69.9%, p = 0.001).
