Abstract

Objective: To describe the characteristics and changes of B-line patterns on lung ultrasound in patients with acute heart failure during treatment. Methods: A descriptive case series was conducted on 45 patients diagnosed with acute heart failure. Lung ultrasound was performed in 4 simplified regions at admission and on subsequent treatment days. Results: The mean B-line index at admission was 23.2 ± 6.9, with positive rates ranging from 86.7% to 100% across regions. The B-line index and the number of B-lines in each region decreased progressively during treatment, with the most significant reduction observed within the first day. Patients in the death/self-discharge group maintained a higher and more fluctuating number of B-lines compared to the discharge/transfer group. Patients with NT-proBNP > 9152.4 pg/mL consistently exhibited higher B-line counts. Those presenting with clinical signs such as crackles, hepatomegaly, and jugular vein distension also had significantly higher B-line numbers. Conclusion: Lung ultrasound is an effective tool for monitoring pulmonary congestion and assessing treatment response in acute heart failure, supporting timely therapeutic decision-making.
