Outcomes of Interventional Management of Coronary Artery Disease in Kidney Transplant Recipients.

ABSTRACT

BACKGROUND: Cardiovascular disease is the most common cause of death among kidney transplant (KT) recipients. Trials routinely exclude patients with end-stage renal disease when assessing the effect of coronary artery revascularization. We looked to compare long-term outcomes in patients who underwent percutaneous coronary intervention (PCI) before KT with those managed medically. METHODS: We identified all patients who underwent coronary artery catheterization before KT from January 2008 to November 2019 at the Cleveland Clinic. The primary endpoint was all-cause mortality. RESULTS: A total of 272 patients were included, of whom 52 (19.11%) underwent PCI, and the remaining 220 patients were managed medically. The median age in the PCI group was 57.4 years (interquartile range [IQR], 46.9-61.2 years), whereas it was 53.9 years (IQR, 44.6-61 years) in the group medically managed. Baseline characteristics including sex, race, hypertension, diabetes, smoking, and hyperlipidemia were comparable in both groups. The median time to KT was 2.4 years (IQR, 1-5 years) in the PCI group vs 1.2 years (IQR, 0.6-3.3 years) in the medically managed group (P = .001). Among patients who underwent PCI, 40.4% had single vessel disease and 59.6% had multivessel disease compared with 16.8% and 28.6%, respectively, in the medically managed group (P < .001). Overall, there was no difference in mortality in the PCI group compared with the medically managed group after 10 years of follow-up (P = .416). CONCLUSIONS: Patients with coronary artery disease can be safely treated with PCI before KT and have comparable outcomes to those who are managed medically.
