Abstract

Background And Aims: The potential impact of peripheral artery disease (PAD) on kidney outcomes is not well understood. The aim of this study was to explore the association between PAD and end-stage kidney disease (ESKD) and chronic kidney disease (CKD).

Methods: Among 14,051 participants (mean age 54 [SD 6 years]) from the Atherosclerosis Risk in Communities study, we categorized PAD status as symptomatic PAD (intermittent claudication or leg revascularization), asymptomatic PAD (ankle-brachial index [ABI] ≤0.90 without clinical history of symptoms), and ABI 0.91-1.00, 1.01-1.10, 1.11-1.20 (reference), 1.21-1.30, and >1.30. We evaluated their associations with two kidney outcomes: ESKD (the need of renal replacement therapy or death due to kidney disease) and CKD (ESKD cases or an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m with a ≥25 % decline from the baseline) using multivariable Cox proportional hazards models.

Results: Over ∼30 years of follow-up, there were 598 cases of incident ESKD and 4686 cases of incident CKD. After adjusting for potential confounders, both symptomatic PAD and asymptomatic PAD conferred a significantly elevated risk of ESKD (hazard ratio 2.28 [95 % confidence interval 1.23-4.22] and 1.75 [1.19-2.57], respectively). Corresponding estimates for CKD were 1.54 (1.14-2.09) and 1.63 (1.38-1.93). Borderline low ABI 0.91-1.00 also showed elevated risk of adverse kidney outcomes after adjustment for demographic variables. Largely consistent results were observed across demographic and clinical subgroups.

Conclusions: Symptomatic PAD and asymptomatic PAD were independently associated with an elevated risk of ESKD and CKD. These results highlight the importance of monitoring kidney function in persons with PAD, even when symptoms are absent.
