Nevertheless, inotropes have been associated with direct cardiac toxicity. Our study evaluated whether the use of high‐dose inotropic support in potential donors was associated with increased early myocardial necrosis (MN) and worse clinical outcomes after cardiac transplantation. Methods: The UTAH Cardiac Transplant Program (UCTP) and Intermountain Donor Services databases were queried for records between 1996 and 2009. The high‐dose donor inotropic support (HDIS) group was defined as patients on dopamine >10 μg/kg/min. The incidence of early MN, intensive care unit (ICU) length of stay, length of ventilator support, and mortality was evaluated. Results: Two hundred and forty‐four recipients undergoing transplant met study criteria. The average donor age was 27 yr. The incidence of MN in the HDIS (n = 29) and non‐HDIS (n = 204) groups was 14.8% and 6.7%, respectively, OR 2.67. Total ischemic time, ventilator support time, ICU stay, and actuarial survival were similar between both groups. Conclusion: The use of high‐dose inotropic support to maintain donor stability appears to have a higher trend for early post‐transplant MN without an impact on clinical outcomes. With the current growing shortage of organ donors, it appears reasonable to use donors on high‐dose inotropic support.
