Heart Failure (HF) is a primary diagnosis for hospital admission in adults from the Emergency Department (ED), but not all patients require hospitalization. Emergency Heart Failure Mortality Risk Grade (EHMRG) is designed to estimate mortality in patients with acute HF in ED settings.


To risk-stratify patients with acute HF using EHMRG scores and assess patient safety.


Retrospective cohort analysis of 304 patients with acute HF presenting to an ED at a large tertiary healthcare center. EHMRG scores were calculated per previous thresholds. Mortality and Major Adverse Cardiac Event (MACE) rates were analyzed.


EHMRG risk group respective seven-day mortality rates 0.0% in very low and low-risk groups. Mortality and MACE rates are significantly less in lower-risk groups at 30 days.


ED risk stratification with EHMRG has the potential to revolutionize care for patients with acute HF. Lower-risk patients may be safely discharged or treated in ED observation units (EDOUs).
