Abstract | OBJECTIVES: METHODS: This retrospective observational study evaluated 142 consecutive hemodialysis patients with symptomatic PAD who underwent EVT (men: n = 103, age: 74 ± 8 years). Patients were divided into 3 groups in accordance with the reason for hemodialysis: hypertensive nephrosclerosis (HTN [n = 26]), diabetic nephropathy (DN [n = 85]), and chronic glomerulosclerosis (CGN [n = 31]). The primary outcome was major adverse event(s) (MAEs), including target lesion revascularization, major amputation, and all-cause death. Clinical characteristics and outcomes were compared among the 3 groups. RESULTS: Patients with HTN were older (81 ± 6 years vs. 72 ± 8 years vs. 74 ± 8 years; P < 0.001) and had a shorter hemodialysis vintage (2.4 years vs. 6.8 years vs. 11.2 years; P < 0.001) than those with DN and CGN. Critical limb ischemia (CLI) affected 15 (58%) patients in the HTN group, 52 (61%) in the DN group, and 10 (32%) in the CGN group. Target lesion length was longer in patients with HTN than in those in the other groups (155 ± 101 mm vs. 108 ± 77 mm [DN] vs. 98 ± 76 mm [CGN]; P = 0.020). During a median follow-up period of 372 days (interquartile range, 198-730 days), Kaplan-Meier curve analysis revealed that HTN was associated with an increased risk for MAEs (χ2 11.6; P = 0.003). Furthermore, multivariate Cox regression analysis revealed that CLI, HTN, and B-type natriuretic peptide levels were independent predictors of MAE (hazard ratio 3.91, 2.88, and 1.00; P < 0.001, P < 0.001, and P = 0.001, respectively). CONCLUSIONS: Among hemodialysis patients with PAD, HTN was associated with an increased risk for MAEs after EVT.
