Outpatient inotropic therapy in heart transplant candidates: should its use influence waiting list priority status?

Abstract

This study suggests that heart transplant candidates who require maintenance outpatient intravenous inotropic therapy represent a subgroup of UNOS status 2 candidates with greater waiting list morbidity, but no greater waiting list mortality than candidates who can be maintained on oral heart failure agents alone. However, the current UNOS heart allocation system provides for this increased illness acuity by assigning a higher priority status when necessary. A larger, prospective study is necessary to determine whether a true difference in waiting list mortality rates exists and if an increase in priority status is justified for UNOS status 2 candidates requiring maintenance inotropic therapy.
