It is very important to assess pulmonary oedema in patients with acute heart failure. The aim of the study was to investigate the accuracy of lung ultrasound in evaluating pulmonary oedema and to explore lung ultrasound in predicting the prognosis. One hundred twenty-four acute heart failure patients were divided into 3 groups, according to the total number of lung ultrasound B-lines groups: B-lines < 15 was the mild pulmonary oedema group (33 cases), 15 ≤ B-lines < 30 was the moderate pulmonary oedema group (33 cases), and B-lines ≥ 30 was the severe pulmonary oedema group (58 cases). The PiCCO monitoring system was used in 11 patients and measured 26 times in different clinical situations. EVLWI have a higher positive correlation with B-lines (r = 0.95), compared with NT-proBNP and E/e' (r = 0.72, r = 0.62). During 1 year of follow-up, a multivariate cox regression analysis showed that age, E/e' and B-lines ≥ 30 at admission (C-index of 75%) were risk factors for prognosis. 12-month event-free survival showed a significantly worse outcome was observed in patients with ≥ 30 B-lines at admission. B-lines have a good correlation with EVLWI; age, E/e' and B-lines ≥ 30 at admission were risk factors for prognosis.
