Methods: An observational study of 240 consecutive non-critical patients \u226550 years admitted with dyspnoea was conducted. Unstable AHF cases were deemed ineligible. Each modality was evaluated at the population level with area under the curve (AUC), sensitivity, and specificity, and compared at the patient level using conditional odds ratio for the association to AHF adjudicated by blinded cardiologists. Congestion was defined by LUS as (a) \u22653 B-lines bilaterally, or (b) B-lines combined with pleural effusion, and (c) CXR, interpreted by two thoracic radiologists, using (d) LDCT as an objective comparator. Results: Among 240 patients (66 with cardiologist-adjudicated AHF, 58 with chronic heart failure), LUS (b) demonstrated a diagnostic accuracy at population level of AUC = 0.82 (sensitivity = 80%, specificity = 84%), while CXR (c) achieved AUC = 0.80 (sensitivity = 68%, specificity = 91%), with CXR showing a modest but statistically significant difference over LUS at the patient level (OR = 1.51, p = 0.03). Incorporating pleural effusion into LUS increased its AUC from 0.67 to 0.82 (a vs. b, p &lt; 0.001). The objective comparator, LDCT (d), achieved an AUC = 0.92 (sensitivity = 74%, specificity = 96%). In patients with chronic heart failure, LUS (b) and CXR (c) performed comparably (p = 0.87), whereas in those without chronic heart failure, CXR was superior (p = 0.04). Conclusions: In non-critical, diagnostically challenging patients with dyspnoea, in whom critical AHF cases were not eligible, including pleural effusion improved LUS accuracy for AHF. Diagnostic performance differed by heart failure history, with CXR superior in new-onset heart failure, while LUS and CXR performed comparably in chronic heart failure.<\/jats:p>","DOI":"10.3390\/diagnostics15233047","type":"journal-article","created":{"date-parts":[[2025,12,2]],"date-time":"2025-12-02T15:31:46Z","timestamp":1764689506000},"page":"3047","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Lung Ultrasound Versus Chest Radiography for Acute Heart Failure: Impact of Heart Failure History and Pleural Effusion"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9544-6114","authenticated-orcid":false,"given":"Kristina Cecilia","family":"Miger","sequence":"first","affiliation":[{"name":"Department of Cardiology, Copenhagen University Hospital\u2013Bispebjerg and Frederiksberg, 2200 Copenhagen, Denmark"},{"name":"Department of Clinical Medicine, University of Copenhagen, 2200 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7783-7357","authenticated-orcid":false,"given":"Anne Sophie","family":"Overgaard Olesen","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Copenhagen University Hospital\u2013Bispebjerg and Frederiksberg, 2200 Copenhagen, Denmark"},{"name":"Department of Clinical Medicine, University of Copenhagen, 2200 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5511-4668","authenticated-orcid":false,"given":"Johannes","family":"Grand","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Copenhagen University Hospital\u2013Amager and Hvidovre, 2650 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8774-6563","authenticated-orcid":false,"given":"Mikael Ploug","family":"Boesen","sequence":"additional","affiliation":[{"name":"Department of Clinical Medicine, University of Copenhagen, 2200 Copenhagen, Denmark"},{"name":"Department of Radiology, Copenhagen University Hospital\u2013Bispebjerg and Frederiksberg, 2200 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3621-3775","authenticated-orcid":false,"given":"Jens Jakob","family":"Thune","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Copenhagen University Hospital\u2013Bispebjerg and Frederiksberg, 2200 Copenhagen, Denmark"},{"name":"Department of Clinical Medicine, University of Copenhagen, 2200 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3532-9431","authenticated-orcid":false,"given":"Olav","family":"Wendelboe Nielsen","sequence":"additional","affiliation":[{"name":"Department of Clinical Medicine, University of Copenhagen, 2200 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1569","DOI":"10.1093\/ehjci\/jead169","article-title":"Lung ultrasound in acute and chronic heart failure.
