BACKGROUND: We previously reported that the incidence of 1-year major adverse cardiac events (MACE) in patients treated with paclitaxel-eluting stents (PES) was lower than that in the sirolimus-eluting stents in dialysis patients. However, it remains unclear whether there are differences in clinical outcomes between everolimus-eluting stents (EES) and PES. METHODS: Between February 2010 and September 2013, 102 maintenance dialysis patients with 135 lesions treated with EES were compared to 107 maintenance dialysis patients with 147 lesions treated with PES. One-year clinical outcomes were investigated. RESULTS: Diabetes mellitus was present in 64.7% in the EES group and 71.0% in the PES group (p = 0.33). Heavy calcification was in 27.4% vs. 34.0% (p = 0.23). Rotational atherectomy was undergone in 11.1% vs. 23.1% (p < 0.01). Total stented length was not significantly different (23.5 ± 14.6 mm vs. 24.4 ± 13.2 mm, p = 0.60). One patient in the EES group was lost to follow up. At 12 months, MACE occurred in 13.2% in the EES group and 17.4% in the PES group (p = 0.25). Target lesion revascularization (TLR) was observed in 9.5% vs. 10.4% respectively (p = 0.77). Mortality was 11.8% vs. 13.1% (p = 0.35). Cardiac death was 5.0% vs. 7.7% (p = 0.09). Definite stent thrombosis was observed in 2.0% vs. 0% (p = 0.14). Subgroup analysis in patients with diabetes mellitus revealed no significant differences in MACE (12.7% vs. 14.9%, p = 0.36), TLR (8.3% vs. 7.4%, p = 0.42), mortality (13.7% vs. 13.2%, p = 0.28), and cardiac death (6.3% vs. 8.0%, p = 0.15) between the two groups. CONCLUSIONS: One-year clinical outcomes following EES and PES implantations are similar in dialysis patients.
