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.
