|Summary||Background: Renal transplantation (RTx) is one of the great options for hemodialysis (HD) patients to improve their life expectancy, however, little is known about outcomes of renal transplantation patients who underwent percutaneous coronary intervention (PCI). The purpose of the present study was to elucidate the impact of RTx on clinical outcomes after PCI.
Methods: Consecutive 50 RTx patients undergoing PCI from 2002 to 2017 were enrolled. To evaluate the effectiveness of RTx, we retrospectively reviewed HD patients who underwent PCI at the same period. Propensity score matching was performed using logistic regression to control for differences in baseline characteristics. The primary outcome was the incidence of major adverse cardiac event (MACE: a composite of all cause death, non-fatal myocardial infarction [MI] and target vessel revascularization [TVR]).
Results: After propensity matching, 100 patients were classified into the RTx (n=50) and HD (n=50) groups. Median follow up period: 53.5 months (interquartile range, 23.8-79.3). Kaplan-Meier analysis revealed that the incidence of MACE in RTx group was significantly lower than in HD group (P< 0.0001). Moreover, RTx group was associated with lower risk for all cause death (odds ratio [OR]: 0.23; 95% confidence interval [CI]: 0.05 to 0.72; p = 0.01) and TVR (OR: 0.12; 95% CI: 0.04 to 0.29; p < 0.0001).
Conclusion: Our present results suggest that RTx may improve not only life expectancy but also TVR after PCI.
