Background: Reduced kidney function is an independent risk factor for cardiovascular disease in the general population. However, the association between post-transplantation graft function and subsequent cardiovascular disease remains uncertain. Therefore, we investigated the outcomes of transplantation in kidney transplant recipients.
Methods: A total of 2,419 kidney transplant recipients in a multicenter cohort were included to evaluate the effects of post-transplant graft function on major adverse cardiovascular events (MACE: cardiac death, nonfatal myocardial infarction, or coronary revascularization), graft failure, and mortality. Recipients were classified into 3 groups according to their estimated glomerular filtration rate (eGFR): group 1 (eGFR ≥ 60 mL/min/1.73 m2, n=1,441), group 2 (30 ≤ eGFR < 60 mL/min/1.73 m2, n=907), and group 3 (eGFR < 30 mL/min/1.73 m2, n=71). Multivariate Cox hazard model was used to explore the association of eGFR with MACE.
Results:Median age was 42 years and 58.8% were male. Median eGFR was 63.6 mL/min/1.73 m2. In 2,419 participants, there were 93 cases of MACE, 214 cases of graft failure, and 76 patient deaths over a median of 6.1 years. The cumulative rates of MACE were higher in the group of lower graft function. In multivariate Cox regression, lower graft function was significantly associated with the occurrence of MACE (hazard ratio 1.5, 95% confidence interval 1.0–2.3, P[thinsp]=[thinsp]0.04) compared to higher graft function.Additionally, cumulative rates of graft failure and mortality were also significantly higher in recipients with lower graft function.
Conclusion:Post-transplant graft function independently correlates with MACE, graft failure, and mortality, suggesting management of graft function may improve the patient and graft survival and cardiac outcome of kidney transplant recipients.
