简介：
Overview
This protocol targets the limited transplantation organ supply issue by facilitating the evaluation of different cardioprotective conditioning strategies to allow the use of hearts donated after circulatory death. It provides a simple and flexible approach for assessing new conditioning agents or strategies.
Key Study Components
