BACKGROUND: This study investigates the impact of end-stage renal disease (ESRD) on systemic and localized outcomes in peripheral artery disease (PAD) patients following endovascular therapy (EVT), with a focus on major adverse cardiac and cerebrovascular events (MACCEs). METHODS: This retrospective cohort study included symptomatic PAD patients, categorized by the Rutherford classification, who underwent EVT at a single tertiary medical center from May 2018 to May 2021. Patients were divided into ESRD and non-ESRD groups. A propensity score-matched (PSM) analysis was performed to minimize confounding factors. The primary outcome was the occurrence of MACCEs, while the secondary outcome was the incidence of major adverse limb events (MALEs). RESULTS: ESRD patients exhibited significantly worse systemic outcomes, with higher MACCE rates compared to non-ESRD patients in both the entire cohort (79.9% vs. 39.9%; HR: 2.69; 95% CI: 1.80-4.02; p < 0.001) and the matched cohort (HR: 3.88; 95% CI: 2.30-6.53; p < 0.001). They also had higher rates of all-cause mortality and myocardial infarction (MI). For localized outcomes, MALEs were more frequent in the ESRD group in the entire cohort (61.0% vs. 34.9%; HR: 1.84; 95% CI: 1.22-2.76; p < 0.001), but no significant difference was observed in the matched cohort (HR: 1.23; 95% CI: 0.76-1.99; p = 0.40). ESRD was identified as the sole independent predictor of increased MACCE risk (HR: 2.49; 95% CI: 1.65-3.75; p < 0.001). CONCLUSIONS: PAD patients with ESRD face significantly worse systemic outcomes, particularly elevated MACCE rates, after EVT. Preventing MACCEs, especially MI, is essential in this high-risk population. Despite more severe limb conditions, ESRD alone did not significantly increase MALE risk after PSM.

背景:本研究调查终末期肾病(ESRD)对接受血管内治疗(EVT)的外周动脉疾病(PAD)患者全身和局部预后的影响,重点关注主要不良心脑血管事件(MACCEs)。 方法:这项回顾性队列研究纳入了根据卢瑟福分类法分类的有症状的PAD患者,这些患者于2018年5月至2021年5月在一家三级医疗中心接受了EVT。患者分为ESRD组和非ESRD组。进行倾向评分匹配(PSM)分析以尽量减少混杂因素。主要结局是MACCEs的发生,次要结局是主要不良肢体事件(MALEs)的发生率。 结果:在整个队列(79.9%对39.9%;HR:2.69;95%CI:1.80 - 4.02;p < 0.001)和匹配队列(HR:3.88;95%CI:2.30 - 6.53;p < 0.001)中,ESRD患者的全身预后明显更差,MACCE发生率高于非ESRD患者。他们的全因死亡率和心肌梗死(MI)发生率也更高。对于局部预后,在整个队列中ESRD组的MALEs更常见(61.0%对34.9%;HR:1.84;95%CI:1.22 - 2.76;p < 0.001),但在匹配队列中未观察到显著差异(HR:1.23;95%CI:0.76 - 1.99;p = 0.40)。ESRD被确定为MACCE风险增加的唯一独立预测因素(HR:2.49;95%CI:1.65 - 3.75;p < 0.001)。 结论:ESRD的PAD患者在EVT后全身预后明显更差,尤其是MACCE发生率升高。在这个高危人群中预防MACCEs,尤其是MI,至关重要。尽管肢体状况更严重,但在PSM后单独的ESRD并未显著增加MALE风险。 临床试验编号:不适用。
