Emergency Heart Failure Mortality Risk Grade calculator
Enter the published formula inputs below to calculate and interpret this score.
Clinical inputs
Allowed range: 18–120 years
Allowed range: 40–300 mmHg
If the value is above 160 mm Hg, 160 is used.
Allowed range: 20–250 bpm
A rate below 80 uses 80. A rate above 120 uses 120.
Allowed range: 50–100 %
If the value is above 92%, 92 is used.
Allowed range: 0.1–20 mg/dL
The equation multiplies mg/dL by 20. A value in µmol/L is divided by 88.4 first.
Allowed range: 1–9 mmol/L
4.0 to 4.5 scores 0. 4.6 or higher scores 30. 3.9 or lower scores 5. A value above 4.5 and below 4.6 has no printed row.

Lee DS et al. Prediction of heart failure mortality in emergent care. Ann Intern Med. DOI: 10.7326/0003-4819-156-11-201206050-00003. PMID: 22665814. EHMRG = 2×age + 60 if transported by EMS − capped systolic pressure + clamped heart rate − 2×capped oxygen saturation + 20×creatinine in mg/dL + potassium points + 60 if troponin is above the upper limit + 45 if active cancer + 60 if metolazone is taken at home + 12. Systolic pressure above 160 uses 160. Heart rate below 80 uses 80 and above 120 uses 120. Saturation above 92% uses 92. Creatinine in µmol/L is divided by 88.4. Potassium 4.0–4.5 scores 0, 4.6 or higher scores 30, and 3.9 or lower scores 5. Not for dialysis-dependent patients. (2012)
