Background: Lung ultrasound (LUS) has been proposed as a reliable tool to evaluate pulmonary congestion (PC) through B-lines assessment despite different described methodologies. We aim to test different LUS methodologies performance in a heart failure (HF) outpatient evaluation.
Methods: 97 advanced systolic HF patients (age 52±9yrs, 61% male, 48% dilated cardiomyopathy) were evaluated by 3 different LUS methodologies: 4 points-scheme (anterior left and right hemithorax wall is divided into upper and lower halves); 8 points-scheme (left and right hemithorax wall is divided into anterior and lateral, upper and lower halves); 28 points-scheme (anterior and lateral right and left hemithorax are scanned from the 2nd to the 5th intercostal spaces, along the parasternal, mid-clavicular, anterior axillary and mid-axillary lines). For all schemes, 2 different approach were followed: B-lines score; positive exam as the presence of >2 B-lines in >2 scanning sites bilaterally. ROC analysis was performed to determine the accuracy of the 6 different methods. A combined NT-proBNP + echocardiography method (COMB) was used as reference for PC.
Results: All schemes were feasible in all patients. PC was present in 75% of the patients according to COMB. Different LUS methodologies performances are summarized in the Table.
Conclusions: B-lines score method performed with the 8 or 28-points schemes have a similar accuracy in PC assessment and could be applied for a quick and reliable evaluation of PC in HF outpatients.
