Abstract
- 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<50%, n=50). Spearman's correlation was used to evaluate associations of B-lines with E/eʹ, NT-proBNP, and EF in the two groups. Receiver operating characteristic (ROC) analysis was performed to compare B-lines with the E/eʹ ratio. Results Results revealed no significant differences were observed in the B-lines between the HFpEF and HFrEF groups. However, compared with the control group, B-lines were significantly increased in the HFpEF and HFrEF groups ( P<.05). The B-lines were positively correlated with E/eʹ (r=0.742, r=0.52) and NT-proBNP (r=0.678, r=0.417) but were negatively correlated with EF (r=−0.365, r=−0.337), and the correlation coefficients were higher in the HFpEF group than in the HFrEF group. In ROC analyses, considering E/eʹ ≥14 as a reference, B-lines yielded a C-statistic value of 0.94 (sensitivity 92%, specificity 83%) in the HFpEF group and 0.84 (sensitivity 86%, specificity 78%) in the HFrEF group. Conclusions B-lines were significantly correlated with the more established parameters of ADHF. The correlation between B-lines and E/eʹ was better, especially in the HFpEF group.
