P1655Lung ultrasound B-lines in patients with acute heart failure and comorbidities

Abstract Background Lung ultrasound assessment of B-lines is a sonographic method for a semi-quantitative evaluation of extravascular lung water, that can be employed to asssess and monitor pulmonary congestion in acute heart failure. Purpose To assess the degree and changes in B-lines during hospitalization for acute heart failure, independently of the etiology, and their correlation with patients' comorbidities. Methods Two-hundred and forty-one complete antero-lateral B-lines assessments were recorded in an old population of 73 patients (mean age 83.0±7.6 years, 54.8% males) admitted with a diagnosis of acute heart failure (AHF). Chronic obstructive pulmonary disease (COPD) was present in 30% patients, chronic kidney disease (CKD) was present in 31% patients, a previously known cardiac condition was present in 73% of patients. B-lines were evaluated according to standard protocol at admission (T1), at 24 hours (T2), 48 hours (T3) and at discharge (T4). NT-proBNP was assessed at admission and at discharge. Results Mean antero-lateral B-lines at T1 were 42±39 with a statistically significant reduction at T3 (25±23, p
