Emergency Heart Failure Mortality Risk Grade (EHMRG)

Sum of point bands for age, triage vitals, EMS transport, potassium, creatinine, troponin, cancer, and metolazone.

Age

Systolic blood pressure (triage; scored up to 160 mmHg)

Heart rate (triage; scored between 80–120 bpm)

Oxygen saturation (lowest triage; scored up to 92%)

Creatinine (µmol/L)

Serum potassium

≤3.9 mmol/L (+54) 4.0–4.5 mmol/L (0) ≥4.6 mmol/L (+30)

Transported by EMS (+60) Troponin above upper limit of normal (+60) Active cancer (+45) Metolazone use at home (+60) ST-segment depression on 12-lead ECG (EHMRG30-ST adjunct; +30 teaching)
