Nutritional status has been reported to be a predictor of the outcomes of critical limb ischemia. However, there have been no reports of the association between nutritional status and the prognosis of patients with intermittent claudication (IC). The aim of this study was to examine whether or not the geriatric nutritional risk index (GNRI) is independently associated with the long-term outcomes of elderly patients following open bypass for IC.Methods and Results:The preoperative nutritional status of patients aged ≥65 years undergoing infrainguinal bypass for IC between 1991 and 2017 was retrospectively evaluated using the GNRI. Patients were divided into 3 groups based on the GNRI: Group I (normal nutritional risk), GNRI &gt;98; Group II (low nutritional risk), GNRI 92 to ≤98; Group III (moderate to high nutritional risk), GNRI &lt;92. The amputation-free survival (AFS), overall survival, and freedom from cardiovascular death up to 5 years were calculated by Kaplan-Meier method and a multivariate analysis was performed to detect independent predictors of each outcome. Group I showed superior outcomes to Group III for each of the 3 outcomes and the multivariate analysis showed that GNRI was an independent predictor of AFS.
