Predicting Survival After Impella Implantation in Patients with Cardiogenic Shock: The J-PVAD Risk Score

Eur J Heart FailPublished

  • Risk prediction model development and validation study (registry)
  • nationwide registry
  • random derivation/validation split
  • backward stepwise logistic regression

Authors' conclusion

The J-PVAD risk score can be calculated using variables easily obtained in routine clinical practice. It helps the accurate stratification of mortality risk and facilitates clinical decision-making.
