Abstract
Context: Acute dyspnea is a frequent complaint in patients attending the emergency department (ED).
Objective: To evaluate the accuracy of PCT, MR-proANP, MR-proADM, copeptin and CT-proET1 for the risk-stratification of severe acute dyspnea patients presenting to the ED.
Methods: Multicenter prospective study in adult patients with a chief complaint of acute dyspnea. Pro-hormone type biomarkers concentrations were measured on arrival. Combined primary endpoint was a poor outcome.
Results: Three hundred and ninety-four patients were included, 137 (35%) met the primary endpoint. MR-proADM was the only biomarker associated with the primary endpoint (odds ratio 1.43 [95%CI: 1.13–1.82], p = 0.003) as were the presence of paradoxical abdominal breathing (odds ratio 2.48 [95%CI: 1.31–4.68]) or cyanosis (odds ratio 3.18 [1.46–6.89])
Conclusions: In patients with severe acute dyspnea in the ED, pro-hormone type biomarkers measurements have a low added value to clinical signs for the prediction of poor outcome.
