BACKGROUND: There are little available data about the impact of geriatric nutritional risk index (GNRI) on clinical outcomes following endovascular therapy (EVT) in chronic limb-threatening ischemia (CLTI) regarding the severities of renal dysfunction (RD).
AIMS: The aim of this study is to evaluate the impact of GNRI on clinical outcomes following EVT in CLTI regarding the severities of RD.
METHODS: We enrolled 705 consecutive CLTI cases treated with EVT between January 2010 and December 2019 at our hospital. The GNRI on admission was calculated as follows: [14.89 × albumin (g/dL)] + [41.7 × (body weight/ideal body weight)]. Study population were divided into 2 groups based on the median GNRI: low group (GNRI < 92) and high group (GNRI ≥ 92). Next, study population was divided to 3 groups according to estimate glomerular filtration rate (eGFR), which was defined as early RD group (60 ≤ eGFR), advanced RD group (15 ≤ eGFR < 60), and end-stage renal dysfunction (ESRD) group (eGFR < 15). The primary endpoint was 2-year amputation-free survival (AFS).
RESULTS: The median follow-up duration was 25.2 months. Amputation-free survival was significantly lower in the low GNRI group regardless of any severities of RD (59.1% vs 90.2%, Log Rank P<0.001 in early RD group, 59.6% vs 80.8%, Log Rank P=0.011 in advanced RD group, 32.8% vs 61.1%, Log Rank P<0.001 in ESRD group).
CONCLUSION: The decrease of GNRI could predict clinical outcomes in CLTI following EVT regardless of any severities of RD based on eGFR.Clinical ImpactThe decrease of geriatric nutritional risk index was associated with worse outcomes in chronic limb-threatening ischemia following endovascular therapy regardless of any severities of renal dysfunction. Because both renal dysfunction and chronic limb-threatening ischemia could potentially have any inflammation, the geriatric nutritional risk index, which can reflect both nutrition-related risks and inflammation severity, can be a plausible marker in predicting adverse events after endovascular therapy in chronic limb-threatening ischemia patients with renal dysfunction.
