Abstract

Objective: Although chronic kidney disease (CKD) and diabetes are important prognostic factors in patients with peripheral artery disease, there are limited data regarding the outcomes of endovascular treatment (EVT) according to the severity of CKD, especially in the presence of diabetes. This study sought to compare clinical outcomes of lower limb EVT between patients with and patients without CKD according to the presence of diabetes. Methods: Patients were enrolled from the Korean multicenter EVT registry and were divided according to the presence of diabetes, then further stratified by CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2). The primary outcome was major adverse limb events (MALEs; a composite of reintervention for target limb, reintervention for target vessel, and unplanned major amputation) at 2 years. Results: A total of 3045 patients were eligible for analysis: 1277 nondiabetic patients (944 without CKD, 333 with CKD) and 1768 diabetic patients (951 without CKD, 817 with CKD). CKD was associated with a significantly increased risk of MALEs after EVT in diabetic patients (14.4% vs 9.9%; adjusted hazard ratio, 1.60; 95% confidence interval, 1.28-2.01; P <.001) but not in nondiabetic patients (7.6% vs 9.7%; adjusted hazard ratio, 0.78; 95% confidence interval, 0.53-1.14; P =.203; interaction P =.018). In analysis stratified by the severity of CKD among diabetic patients, end-stage renal disease was significantly associated with an increased risk of MALE. Conclusions: CKD was associated with a significantly higher risk of MALEs after EVT in diabetic patients but not in nondiabetic patients. The increased risk of MALEs was mainly driven by patients with end-stage renal disease.
