Prediction of Donor Heart Acceptance for Transplant and Its Clinical Implications: Results From The Donor Heart Study

Circ Heart FailPublished Retrospective cohort study

Authors' conclusion

Predictors of donor heart acceptance for transplantation have changed significantly over the last 2 decades, likely reflecting evolving evidence regarding their impact on posttransplant outcomes.

Main finding

As reported in the abstract

Predictors of donor heart acceptance

Older age increasingly predictive of discard over time (time interaction)

0.0001

Drug use, infection and mild cardiac diagnostic abnormalities less influential over time (time interaction)

<0.05 for all

Observational data: associations, not effects.
