Aim: Acute heart failure can be a life‐threatening medical condition. Delaying administration of intravenous furosemide (time‐to‐diuretics) has been postulated to increase mortality, but prior reports have been inconclusive. We aimed to evaluate the association between time‐to‐diuretics and mortality in the international REPORT‐HF registry. Methods and results: We assessed the association of time‐to‐diuretics within the first 24 h with in‐hospital and 30‐day post‐discharge mortality in 15 078 patients from seven world regions in the REPORT‐HF registry. We further tested for effect modification by baseline mortality risk (ADHERE risk score), left ventricular ejection fraction (LVEF) and region. The median time‐to‐diuretics was 67 (25th–75th percentiles 17–190) min. Women, patients with more signs and symptoms of heart failure, and patients from Eastern Europe or Southeast Asia had shorter time‐to‐diuretics. There was no significant association between time‐to‐diuretics and in‐hospital mortality (p > 0.1). The 30‐day mortality risk increased linearly with longer time‐to‐diuretics (administered between hospital arrival and 8 h post‐hospital arrival) (p = 0.016). This increase was more significant in patients with a higher ADHERE risk score (pinteraction = 0.008), and not modified by LVEF or geographic region (pinteraction > 0.1 for both). Conclusion: In REPORT‐HF, longer time‐to‐diuretics was not associated with higher in‐hospital mortality. However, we did found an association with increased 30‐day mortality, particularly in high‐risk patients, and irrespective of LVEF or geographic region.
