Outcomes of Renal Transplant Recipients after Percutaneous Coronary Intervention.

Renal transplantation (RT) can improve life expectancy in hemodialysis (HD) patients. However, little is known about the outcomes of renal transplant recipients after percutaneous coronary intervention (PCI). This study aimed to elucidate the effect of RT on clinical outcomes after PCI. Renal transplant recipients who underwent PCI from 2002 to 2017 were enrolled. To evaluate the effectiveness of RT, we retrospectively reviewed HD patients who underwent PCI. 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 events. After propensity matching, patients were classified into the RT (n=50) group and HD (n=50) group. Kaplan-Meier analysis revealed that the incidence of major adverse cardiac events was significantly lower in the RT group than in the HD group (p < 0.0001). Moreover, RT was associated with a lower risk for all-cause death (odds ratio 0.04; 95% confidence interval 0.002 to 0.03; p=0.0054) and target vessel revascularization (OR 0.27; 95% CI 0.07 to 0.79; p=0.015). RT may improve clinical outcomes after PCI, and it is encouraged for HD patients to increase life expectancy and reduce the occurrence of adverse events after PCI. Further research would be warranted to support this finding.
