The application of lung ultrasound in acute decompensated heart failure in heart failure with preserved and reduced ejection fraction

Objectives Lung ultrasound detection of B-lines has become a simple, semiquantitative, noninvasive tool for evaluating pulmonary congestion in heart failure (HF) patients. This study compared the correlation of B-lines with E/eʹ, NT-proBNP, and ejection fraction (EF) in acute decompensated heart failure (ADHF). Methods Eighty-two consecutive patients who were diagnosed with acute decompensated HF were divided into two groups: preserved ejection fraction heart failure (HFpEF, EF≥50%, n=32) and reduced ejection fraction heart failure (HFrEF, EF
