Accuracy of Point-of-Care B-Line Lung Ultrasound in Comparison to NT-ProBNP for Screening Acute Heart Failure.

AIM The objective of this pilot study was to determine the accuracy of point-of-care B-line lung ultrasound in comparison to NT Pro-BNP for screening acute heart failure. MATERIALS AND METHODS An 8-zone lung ultrasound was performed by experienced sonographers in patients presenting with acute dyspnea in the ED. AHF was determined as the final diagnosis by 2 independent reviewers. RESULTS Contrary to prior studies, B-line ultrasound in our study was highly specific, but moderately sensitive for identifying patients with AHF. There was a strong association between elevated NT-proBNP levels and an increased number of B-lines. CONCLUSION In conclusion, point-of-care lung ultrasound is a helpful tool for ruling in or ruling out important differential diagnoses in ED patients with acute dyspnea.
