[Epidemiology of patients presenting to the emergency room for dyspnea in Belgium].

Studies about patients' profile presenting to the emergency department for dyspnea are scarce in Europe, and even more in Belgium. We analyze here a cohort of patients with acute dyspnea in three Belgian centers, as to the epidemiology of this dyspnea, the tests carried out, the diagnoses retained, the treatments administered, the hospitalization and survival rates. The secondary objective is to compare this Belgian cohort with a European population resulting from a large multicenter study.
