MECKI Score (CPET-anchored HF Prognosis)
MECKI score: a CPET-anchored model estimating the 2-year risk of cardiovascular death, urgent transplant, or LVAD in systolic heart failure from hemoglobin, sodium, LVEF, percent-predicted peak VO₂, VE/VCO₂ slope, and MDRD-eGFR.

Example
- Hemoglobin
- 10 g/dL
- Sodium
- 132 mEq/L
- LVEF
- 25 %
- Peak VO₂
- 40
- VE/VCO₂ slope
- 40
- MDRD-eGFR
- 45 mL/min/1.73 m²
Result: MECKI 40.7% — estimated 2-year risk of cardiovascular death, urgent transplant, or LVAD; higher-risk range (≥ 30%).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Meaning
- The score is the model’s estimated 2-year risk of cardiovascular death, urgent transplant, or LVAD. Higher = worse; a CPET-anchored prognostic estimate, not a transplant or device order.
What you enter
- Hemoglobin
- Sodium
- LVEF
- Peak VO₂ (% predicted)
- VE/VCO₂ slope
- MDRD-eGFR
How this is calculated
- Formula
- LP = 10.3464 − 0.0262·ppVO₂ + 0.0472·(VE/VCO₂ slope) − 0.1086·Hb − 0.0615·Na − 0.0699·LVEF − 0.0136·eGFR; score = 1/(1+e^−LP) as a percentage.
