Objective: Cardiac transplantation (OHT) using diabetic donors (DDs) is thought to adversely influence survival. We attempt to determine if adult OHT can be safely performed using selected DDs.
Methods: The United Network for Organ Sharing (UNOS) database was examined for adult OHT from 2000 to 2010.
Results: Of the 20,348 patients undergoing OHT, 496 (2.4%) were with DDs. DDs were older (39.6 vs 31.3 years; P < .001), more likely female (41.5% vs 28.3%; P < .001), and had a higher body mass index (BMI) (29.9 vs 26.4; P < .001). Recipients of DD hearts were older (53.4 vs 51.8; P = .004) and more likely to have diabetes (18.9% vs 14.9%; P = .024). The 2 groups were evenly matched with regard to recipient male gender (78.0% vs 76.1%; P = .312), ischemic time (3.3 vs 3.2 hours; P = .191), human leukocyte antigen mismatches (4.7 vs 4.6; P = .483), and requirement of extracorporeal membrane oxygenation (ECMO) as a bridge to transplant (0.8% vs 0.5%; P = .382). Median survival was similar (3799 vs 3798 days; P = .172). On multivariate analysis, DD was not associated with mortality (hazard ratio [HR], 1.155; 95% confidence interval [CI], 0.943-1.415; P = .164). As previously demonstrated, donor age, decreasing donor BMI, ischemic time, recipient creatinine, recipient black race, recipient diabetes, race mismatch, and mechanical ventilation or ECMO as a bridge to transplant were associated with mortality. On multivariate analysis of subgroups, neither insulin-dependent diabetes (1.173; 95% CI, 0.884-1.444; P = .268) nor duration of diabetes for more than 5 years (HR, 1.239; 95% CI, 0.914-1.016; P = .167) was associated with mortality.
Conclusions: OHT can be safely performed using selected DDs. Consensus criteria for acceptable cardiac donors can likely be revised to include selected DDs.
