The role of gender in heart transplantation.

Abstract

The effect of donor and recipient gender on the outcome of heart transplantation (HT) remains uncertain. One hundred seventy-four patients who underwent HT were divided into four groups according to donor and recipient gender. Group A consisted of 81 men who received male donor hearts, group B of 18 women who received female donor hearts, group C of 21 women who received male donor hearts, and group D of 54 men who received female donor hearts. All patients were treated by the same group of surgeons according to standard HT protocols. Comparisons were made between groups with regard to short- and long-term outcomes. Donor gender and recipient gender did not affect outcomes significantly. Overall, donor-recipient gender mismatching significantly increased the number of rejection episodes and reduced creatinine clearance, survival, and censored survival in the first year after HT (p < 0.05). More specifically, among female recipients, donor-recipient gender mismatching significantly increased the number of rejection episodes and decreased creatinine clearance in the first year after HT (p < 0.05); among male recipients, donor-recipient gender mismatching significantly reduced 1-year survival and censored survival to date after HT (p < 0.05). Donor-recipient gender matching plays a significant role in determining HT outcomes.
