    ObjectivesInvestigating whether it is safe or not to administrate diuretics to patients arriving at emergency departments in a stage of acute dyspnea but without a final diagnosis of acute heart failure.MethodsWe analyzed an unselected multinational sample of patients with dyspnea without a final diagnosis of acute heart failure from Global Research on Acute Conditions Team (France, Lithuania, Tunisia) and Basics in Acute Shortness of Breath Evaluation (Switzerland) registries. Thirty-day all-cause mortality and 30-day postdischarge all-cause readmission rate of treated patients with diuretics at emergency departments were compared with untreated patients by unadjusted and adjusted hazard and odds ratios. Interaction and stratified analyses were performed.ResultsWe included 2505 patients. Among them, 365 (14.6%) received diuretics in emergency departments. Thirty-day mortality was 4.5% (treated/untreated = 5.2%/4.3%, hazard ratio: 1.22; 95% confidence interval, 0.75-2.00) and 30-day readmission rate was 11.3% (14.7%/10.8%, odds ratio: 1.41; 95% confidence interval, 0.95-2.11). After adjustment, no differences were found between two groups in mortality (hazard ratio: 0.86; 95% confidence interval, 0.51-1.44) and readmission (odds ratio: 1.15; 95% confidence interval, 0.72-1.82). Age significantly interacted with the use of diuretics and readmission (P = 0.03), with better prognosis when used in patients >80 years (odds ratio: 0.27; 95% confidence interval, 0.07-1.03) than in patients ≤80 years (odds ratio: 1.56; 95% confidence interval, 0.94-2.63).ConclusionsDiuretic administration to patients presenting to emergency departments with dyspnea while they were undiagnosed and in whom acute heart failure was finally excluded was not associated with 30-day all-cause mortality and 30-day postdischarge all-cause readmission rate.
