Buessler A, Chouihed T, Duarte K, et al. - Focusing on the utility of various lung ultrasound (LUS) strategies for recognizing acute heart failure (AHF) in the ED, researchers performed this prospective study in four EDs, involving patients with diagnostic uncertainty depending on initial clinical judgment. They quantified a clinical diagnosis score for AHF (Brest score) and then conducted an extensive LUS test according to the 4-point (BLUE protocol) and 6-, 8-, and 28-point methods. Findings revealed that an improved AHF diagnosis accuracy was afforded by the 6-point/8-point LUS method (using the 1 bilateral positive point threshold) on top of the BREST score in patients with diagnostic uncertainty.
