Intervention / Treatment
Detailed Description
Study protocol After the initial standard work-up, which includes past medical history, history of the present illness, physical examination, ECG, and arterial blood gas analysis, the emergency physician responsible for patient care will be asked to categorize the diagnosis as ADHF or non-cardiogenic dyspnea.
Then, the patient will be assigned to one of the experimental arms. In the LUS arm, the same emergency physician will perform LUS, and express the new integrated presumptive etiology ("LUS-implemented" diagnosis). All patients will then undergo CXR.
In the CXR arm, patients will undergo CXR, and the new integrated etiology will be record after CXR and NT-proBNP results will be available.
After hospital discharge, two expert emergency physicians, blinded to LUS results, will independently review the entire medical record, and indicate the final diagnosis. In case of disagreement, a cardiologist will review the medical records, and adjudicate the case.
Statistical analysis The accuracy of each diagnostic tool will be expressed as sensitivity, specificity, predictive values and likelihood ratios obtained using 2 x 2 tables. "Positive" and "negative" results will be considered, for each test, the diagnosis of ADHF or non-cardiac dyspnea, respectively. Receiver operating characteristic (ROC) and area under curve (AUC) statistics will be also shown.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Lung Ultrasound
In Patients allocated to this arm Lung ultrasound for detection of interstitial syndrome will be performed before chest radiography.
|
Lung ultrasound evaluation is performed after clinical assessment and before chest radiography
|
Experimental: Chest Radiography
In Patients allocated to this arm chest radiography will be performed for the detection of indirect signs of pulmonary congestion/ADHF without ultrasound evaluation.
|
Chest Radiography is performed after clinical evaluation without using ultrasound assessment

Measure Description |
Time Frame |
---|---|---|
Accuracy of Lung Ultrasound and Chest Radiography in dyspnoeic patients
Time Frame: Accuracy will be measured at the end of clinical evaluation in the Emergency Department, an expected average of 2 hours.
|
Accuracy of lung ultrasound and chest radiography will be measured using as gold standard the independent evaluation of the entire medical records by two expert emergency physicians blinded to the lung ultrasound results and radiographic reports (digitalized chest radiography images will be available).
|
Accuracy will be measured at the end of clinical evaluation in the Emergency Department, an expected average of 2 hours.
