BIOmarkers of Dyspnea IN Emergency Room

Prognostic Value of Novel Biomarkers in Patients With Shortness of Breath Attending an Emergency Department

The purpose of this study is to evaluate the capacity of some novels biomarkers Procalcitonin (PCT), Midregional Proadrenomedullin (MR pro ADM), Midregional pro-atrial natriuretic peptide (MR pro ANP), Copeptin (CT pro arginine vasopressin), Pro endothelin to stratify the risk in severe dyspnea.

In emergency department shortness of breath (SOB)is a common symptom and its cause is not easy to be identified. The risk stratifying remains a challenge, Prognostic value of biomarkers might be helpful.
