BACKGROUND: Coronary artery disease is a major cause of death in patients with chronic kidney disease. Moreover, due to the high prevalence of risk factors for atherosclerosis, many of these patients require percutaneous coronary intervention (PCI) even after renal transplantation. The aim of this study is to report the late follow-up of patients with renal transplantation treated with PCI and stenting. METHODS: Patients > 18 years of age, with prior kidney transplantation, and treated with PCI were included. Clinical follow-up was evaluated by medical record analysis and telephone contact. The study endpoint was the incidence of major adverse cardiac events (MACE) during follow-up. RESULTS: Twenty-nine patients were included. Mean age was 54.8 ± 8 years and the majority male (72.4%). The prevalence of hypertension was 89.7%, dyslipidemia 69% and diabetes 51.7%. Most of them had multivessel disease (2-vessel: 44.8%; 3-vessel: 41.4%). Lesion complexity was high, being 84.3% type B2 or C lesions and 27.5% bifurcation lesions. Procedural success rate was 100%. Bare metal stents were used in 96.6% of cases. The follow-up time was 1,378 ± 977 days. The mortality rate was 25.1%, target vessel revascularization rate was 15.9% and none of the patients presented non-fatal infarction. The incidence of MACE during follow-up was 34.5%. CONCLUSIONS: Late follow-up after PCI in renal transplantation patients demonstrated a high probability of clinical events. However, the study population was a sample of high clinical and angiographic complexity.
